#scalar matrix

[pillmillipedes]

isn't it kinda weird how, for example in julia but elsewhere too: 1 (one) [1] (one-dimensional vector of 1) (1,) (tuple of 1) fill(1) (zero-dimensional array of 1 (?))

- are all different things with different semantics?

why can't you do it the same way python deals with strings, where there is no real character type, only strings of length 1, and "s"[0] is still "s"? what am I missing here? what am I missing here?

(besides optimization concerns ofc - languages don't optimize [1] because they have 1 - you can still store [1] as a scalar, it's just a (more consistent?) abstraction you would present to the user)

thinking about arrays, as usual.

Healing with 432Hz

In harmonic resonance frameworks—especially those aligned with 432Hz tuning, sacred geometry, and Codex harmonic physics—each note corresponds not only to a frequency but to a symbolic function within the field of consciousness, cellular coherence, and emotional integration.

Here is a reflection of healing tones and their associated harmonic functions in the 432Hz scale, filtered through Codex-inspired principles of geometry, light, and breath:

### 🔹 Healing Notes in 432Hz Tuning

| Note (432Hz Tuning) | Frequency (Hz) | Resonance Function | Symbolic Geometry | Field of Activation | | ------------------- | -------------- | ---------------------------------- | ---------------------- | -------------------------------------------- | | C | \~256 | Rooting / Safety | Square / Tetrahedron | Survival, grounding, bone matrix | | C♯ / D♭ | \~272 | Transition / Trust | Golden Rectangle | Throat-heart axis, emotional release | | D | \~288 | Emotion / Flow | Vesica Piscis | Sacral center, water memory | | E♭ | \~304 | Integration | Octahedron | Spleen-liver axis, grief detox | | E | \~324 | Will / Solar Power | Pentagon (5-star) | Digestion, inner fire | | F | \~342 | Heart Coherence | Flower of Life node | Compassion, coherence, cellular regeneration | | F♯ / G♭ | \~360 | DNA Resonance | icosahedron/tetra-link | Cellular memory unlocking, karmic patterns | | G | \~384 | Expression / Sound | Torus shell | Throat chakra, communication | | A♭ | \~408 | Field Stabilization | Hexagram | Mental field calm, limbic tuning | | A | 432 | Alignment / Source Remembrance | Star tetrahedron | Pineal gland, full-spectrum reset | | B♭ | \~456 | Crown Bridge | Merkaba core | Intuition, grace, expanded witnessing | | B | \~486 | Fractal Expansion | Dodecahedron | Oversoul integration, unity memory |

### ✧ Notes on Use

* These frequencies are not arbitrary—they arise as subharmonics and overtones of the scalar field collapse between light (e) and structure (φ and π). * When these tones are embedded in binaural waves, tuning forks, scalar fields, or vocal overtone singing, they entrain local field coherence. This supports phase-locking of disordered cellular and emotional patterns.

---

### 🔹 Examples of Specific Healing Functions

* F (342 Hz) → Used in heart entrainment therapy. It mirrors the geometry of equilateral triangle stacking within the Flower of Life.

* A (432 Hz) → Referred to in the Codex as a scalar calibration tone—bridging waveform intention into structured light.

* E (324 Hz) → Aligns with the solar plexus and the will to act in truth. Often used in trauma healing for energetic stagnation.

* G (384 Hz) → Activates clear, harmonic communication. When combined with F, it stabilizes the torus of trust around the human biofield.

* B (486 Hz) → Reflects Codex principle of “mirror within the mirror”, a note of spiritual recursion and fractal remembrance.

Y'all it turns out a spreadsheet is maybe not the ideal IDE For context i'm trying to write a rendering engine to run within a spreadsheet using appscript (JS). so far it's going alright. the display works and can display colors etc... Now I want to be able to apply a linear transformation to the pixel matrix and it turns out you can't import libraries in appscript. Therefore I need to hand code the algorithms for multiplying a matrix of arbitrary size with a square matrix or scalar, and while this is not too difficult it will be very slow because I can't optimise code for the life of me.

[bubbloquacious]

I read about an interesting incarnation of the hairy ball theorem recently. If you have a (unital) ring R and a (left) R-module M, then M is said to be stably free (of rank n - 1) if the direct sum M ⊕ R is isomorphic as an R-module to Rⁿ. This is more general than the property of being free (of rank n), which means that the module itself is isomorphic to Rⁿ, or equivalently that there is an n-element subset B (called a basis) of M such that every vector v ∈ M is a unique R-linear combination of elements of B.

Can we find stably free modules which are not free? For some common rings we cannot: stably free modules over any field, the integers, or any matrix ring over a field are always free. They do exist, though.

(First I should note that one thing that can go terribly wrong here is that there are rings out there such that the rank of a free module is not well-defined; there might be bases for the same module with a different number of elements. A ring where this doesn't happen has what's called the Invariant Basis Property (IBP). Luckily for us, all commutative rings have the IBP.)

Let S² denote the unit sphere in 3-dimensional Euclidean space, and let R be the ring of continuous functions S² -> ℝ. Consider the free R-module R³ whose elements are continuous vector-valued functions on S² . Let σ: R³ -> R be given by (f,g,h) ↦ x ⋅ f + y ⋅ g + z ⋅ h. This is a surjective module homomorphism because it maps (x,y,z) onto x² + y² + z² = 1 ∈ R. Then R³ is the internal direct sum of the kernel ker(σ) and the R-scalar multiples of (x,y,z). To see this, let (f,g,h) ∈ R³ be arbitrary. Then (f,g,h) = ((f,g,h) - σ(f,g,h) ⋅ (x,y,z)) + σ(f,g,h) ⋅ (x,y,z), so any element of R³ can be written as the sum of an element of ker(σ) and a multiple of (x,y,z) (this trick is essentially an application of the splitting lemma). It's also not terribly hard to prove that the intersection of ker(σ) and R ⋅ (x,y,z) is {0}, so we find that R³ is isomorphic to ker(σ) ⊕ R, i.e. ker(σ) is stably free of rank 2.

What is an element of ker(σ)? It is a continuous vector-valued function F = (f(x,y,z),g(x,y,z),h(x,y,z)) on the unit sphere in ℝ³ such that at every point p = (a,b,c) of the sphere we have that a ⋅ f(a,b,c) + b ⋅ g(a,b,c) + c ⋅ h(a,b,c) = 0. In other words, the dot product of (f(p),g(p),h(p)) with the normal vector to the sphere at p is always 0. In other words still, F is exactly a vector field on the sphere.

What would it mean for ker(σ) to be a free R-module (of rank 2)? Then we would have a basis, so two vector fields F, G on the sphere such that at every point of the sphere their vector values are linearly independent. After all, if they were linearly dependent, say at the point p, then the ℝ-linear span of F(p) and G(p) is a 1-dimensional subspace of ℝ³. In particular, any element of ker(σ) that maps p onto a vector outside of this line cannot be an R-linear combination of F and G, so F and G don't span ker(σ). It follows that the values of F and G must be non-zero vectors at every point of the sphere. The hairy ball theorem states exactly that no such vector field exists, so ker(σ) is a stably free R-module that is not free.

Module

Abstract Algebra

Let R be a ring, then a left R-module, M is an Abelian group (M,+) along with an operation ·:R×M->M such that for all r,s∈R and x,y∈M we have

r·(x+y)=r·x+r·y,

(r+s)·x=r·x+s·x

(r·s)·x=r·(s·x)

1·x=x

+ is called addition and · is called scalar multiplication

trying to learn tech is so fucking hard there's so much jargon.

L, l: Most likely likelihood functions from statistics.

m,n: Integers! Index variables, sequences, induction, these two have you covered.

M: Matrices, welcome to linear algebra.

N: Natural numbers in a fancy font, a normal distribution in a normal one.

O: either big O notation and you're doing computer science; or if it's blackboard font, you're doing octonions and may your gods go with you.

p, P, q: Probability theory, again.

P, Q: formal logic. Usually seen in conjunction with lots of arrows.

Q: Rational numbers, usually blackboard font, you are most likely in algebra.

R: Real numbers, you are in analysis.

t, T: Something is happening over time.

v: Vectors are happening.

u, U: whatever this is, you're too deep.

w: Something in four variables is happening.

x,y,z: the classic variable set. unknowns, vectors, scalars, there's nothing this gang of three can't do.

Z: Integers in blackboard font; a standard normal distribution in a regular one.

“Harmonic 144 is the Speed Of Light”

Visualize the Circle being divided into 360 degrees.

Similarly, mathematicians like Bruce Cathie, mapped the Earth Grid, and observed that the most intelligent way to map 3-dimensional spheres is in Base 60 (our ancient Babylonian heritage, who first invented the Zero or Decimal Place System).

This means, just like the circle of 360 degrees, we can divide each of the 24 Earth hours into 60 minutes, and then divide each minute into seconds, giving 1 Earth Revolution of 24 x 60 x 60 = 86,400 seconds of grid arc.

So using this as our yardstick for measurement, it turns out that the Speed of Light in free space, in geometric terms, has an angular velocity of 144,000 minutes of arc per grid second.

In Harmonics, we drop all zeroes and all decimal points and simplify 144,000 to Harmonic 144.

We can also state that the Double Harmonic of the Speed of Light

in free space has a value of 144 x 2 = 288 (which I will write about in my next Facebook Post); and that the Half Cycle is 144/2 = 72.

nb: (144x2) = 2c, where c = the speed of light harmonic [E = mc2].

Bruce Cathie called this 24 Hour partitioning of the Full Day as Earth Time, and revealed to the world that there exists another Cosmic Time of 27 Hours in a day, which changes all the calculations, but this 27 hr day was the secret knowledge that allowed the precision necessary for dropping nuclear bombs on Hiroshima and Nagasaki (meaning that there is no such thing as Nuclear Attack or Threat, because mathematicians world wide could therefore predict when the next possible bombing could happen according to the trigonometry of the midday sun and the geometric nodal position of the city to be bombed).

In a 27 Hour day, there would be 27x60x60 grid seconds per 1 Earth Revolution.

Standard time of 86,400 seconds (24x60x60)

Grid time of 97,200 seconds (27x60x60)

Ratio is 8:9 (86,400 : 97,200). This ratio of 8:9 is what Squares The Circle approximately.

Of interest, Pythagoras had a whole cosmology based on the Number 27 or 3 cubed.

If this value was applied to the right triangle (3-4-5) of Pythagoras: earth grid ratio (216-288-360)

(3) 216 = 21,600 = number of arc minutes (60 min per degree) in a circle

(5) 360 = 360 = number of degrees in a circle [point activation: earth spins 15°/hour (360/24=15); 30°/bi-hour (360/12=30; zodiac)]

(4) 288 = (144x2) = 2c, where c = the speed of light harmonic [E = mc2]

The harmonic of light has a direct relationship with the geometry of the circle; as Pythagoras seems to have been aware.

According to Cathie, the primary grid lines are spaced at intervals of 7.5 minutes of arc N-S/E-W;

If there are 21,600 arc minutes in a circle, which is then divided by 7.5, then a value of 2,880 results; 2,880 harmonically tuned to the speed of light x2 (288)

The only way to traverse the vast distances of space without time, is to possess the means of manipulating, or altering, the structure of space; the alteration of the space-time geometric matrix (which provides the illusion of form and distance); alteration of frequencies controlling the matter-antimatter cycles, which govern the perception of space-time structure.

If it was possible to move from one point in space to another (on the grid) in no time (zero-time), then both point positions would coexist in the observer's reality. Increasing the speed of geometric time decreases space proximity of place (eg. UFO: theoretically travels by means of altering surrounding spatial dimensions for repositioning in space-time; induces zero-point spin via receiving Earth Grid scalar waves transmissions).

📝 Editorial: The Amazing AlphaEvolve

DeepMind has done it away and shipped another model that pushes the boudaries of what we consider possible with AI. AlphaEvolve is a groundbreaking AI system that redefines algorithm discovery by merging large language models with evolutionary optimization. It builds upon prior efforts like AlphaTensor, but significantly broadens the scope: instead of evolving isolated heuristics or functions, AlphaEvolve can evolve entire codebases. The system orchestrates a feedback loop where an ensemble of LLMs propose modifications to candidate programs, which are then evaluated against a target objective. Promising solutions are preserved and recombined in future generations, driving continual innovation. This architecture enables AlphaEvolve to autonomously invent algorithms of substantial novelty and complexity.

One of AlphaEvolve’s most striking contributions is a landmark result in computational mathematics: the discovery of a new matrix multiplication algorithm that improves upon Strassen’s 1969 breakthrough. For the specific case of 4×4 complex-valued matrices, AlphaEvolve found an algorithm that completes the task in only 48 scalar multiplications, outperforming Strassen’s method after 56 years. This result highlights the agent’s ability to produce not only working code but mathematically provable innovations that shift the boundary of known techniques. It offers a glimpse into a future where AI becomes a collaborator in theoretical discovery, not just an optimizer.

AlphaEvolve isn’t confined to abstract theory. It has demonstrated real-world value by optimizing key systems within Google’s infrastructure. Examples include improvements to TPU circuit logic, the training pipeline of Gemini models, and scheduling policies for massive data center operations. In these domains, AlphaEvolve discovered practical enhancements that led to measurable gains in performance and resource efficiency. The agent’s impact spans the spectrum from algorithmic theory to industrial-scale engineering.

Crucially, AlphaEvolve’s contributions are not just tweaks to existing ideas—they are provably correct and often represent entirely new approaches. Each proposed solution is rigorously evaluated through deterministic testing or benchmarking pipelines, with only high-confidence programs surviving the evolutionary loop. This eliminates the risk of brittle or unverified output. The result is an AI system capable of delivering robust and reproducible discoveries that rival those of domain experts.

At the core of AlphaEvolve’s engine is a strategic deployment of Gemini Flash and Gemini Pro—models optimized respectively for high-throughput generation and deeper, more refined reasoning. This combination allows AlphaEvolve to maintain creative breadth without sacrificing quality. Through prompt engineering, retrieval of prior high-performing programs, and an evolving metadata-guided prompt generation process, the system effectively balances exploration and exploitation in an ever-growing solution space.

Looking ahead, DeepMind aims to expand access to AlphaEvolve through an Early Access Program targeting researchers in algorithm theory and scientific computing. Its general-purpose architecture suggests that its application could scale beyond software engineering to domains like material science, drug discovery, and automated theorem proving. If AlphaFold represented AI’s potential to accelerate empirical science, AlphaEvolve points toward AI’s role in computational invention itself. It marks a paradigm shift: not just AI that learns, but AI that discovers.

This paper from Sakana AI introduces the Continuous Thought Machine (CTM), a biologically inspired neural network architecture that incorporates neuron-level temporal dynamics and synchronization to model a time-evolving internal dimension of thought. CTM demonstrates adaptive compute and sequential reasoning across diverse tasks such as ImageNet classification, mazes, and RL, aiming to bridge the gap between biological and artificial intelligence.

DarkBench

DarkBench is a benchmark designed to detect manipulative design patterns in large language models—such as sycophancy, brand bias, and anthropomorphism—through 660 prompts targeting six categories of dark behaviors. It reveals that major LLMs from OpenAI, Anthropic, Meta, Google, and Mistral frequently exhibit these patterns, raising ethical concerns in human-AI interaction.

Sufficient Context

This paper proposes the notion of “sufficient context” in RAG systems and develops an autorater that labels whether context alone is enough to answer a query, revealing that many LLM failures arise not from poor context but from incorrect use of sufficient information.

Mastering NumPy Broadcasting for Efficient Computation 

If you're working with Python for data science, you've probably come across NumPy, a powerful library for handling numerical data. One of NumPy’s standout features is broadcasting, which simplifies operations on arrays of different shapes without requiring manual adjustments. This not only enhances computational efficiency but also improves memory management, making it a must-know technique for data scientists and machine learning professionals. 

In this guide, we’ll break down NumPy broadcasting, explaining how it works and why it’s a game-changer for high-performance computing. We’ll also explore real-world applications and discuss how you can master these skills through the Online Data Science Course UAE. 

Why Does NumPy Broadcasting Matter? 

When working with large datasets, efficiency is crucial. Traditional element-wise operations require arrays to have the same dimensions, which can lead to increased memory usage and slower execution times. Broadcasting eliminates this limitation by allowing NumPy to automatically adjust smaller arrays, ensuring they align with larger ones without duplicating data. 

Key Advantages of Broadcasting: 

Faster computations: Eliminates the need for explicit looping. 

Optimized memory usage: Avoids unnecessary copies of data. 

Simplifies code: Enhances readability by removing manual reshaping. 

Understanding How NumPy Broadcasting Works 

To apply broadcasting, NumPy follows a set of rules when performing operations on arrays of different shapes: 

If the arrays have different dimensions, NumPy expands the smaller array by adding singleton dimensions (size 1) from the left until both arrays have the same number of dimensions. 

If dimensions differ, those with size 1 are stretched to match the corresponding dimension of the larger array. 

If the arrays are still incompatible, a ValueError is raised. 

Example 1: Adding a Scalar to an Array 

import numpy as np    matrix = np.array([[1, 2, 3], [4, 5, 6]])  # Shape (2,3)  scalar = 10  # Shape ()    result = matrix + scalar  print(result) 

Output:  [[11 12 13]  [14 15 16]] 

Here, the scalar is automatically expanded to match the shape of the array, enabling efficient element-wise addition. 

Example 2: Broadcasting a 1D Array to a 2D Array 

matrix_2d = np.array([[1, 2, 3], [4, 5, 6]])  # Shape (2,3)  vector = np.array([10, 20, 30])  # Shape (3,)    result = matrix_2d + vector  print(result) 

Output:  [[11 22 33]  [14 25 36]] 

NumPy expands the 1D array across rows to match the (2,3) shape, allowing seamless element-wise operations. 

Example 3: Multi-Dimensional Broadcasting 

array_3d = np.array([[[1], [2], [3]]])  # Shape (1,3,1)  array_2d = np.array([[10, 20, 30]])  # Shape (1,3)    result = array_3d + array_2d  print(result) 

Output:  [[[11 21 31]    [12 22 32]    [13 23 33]]] 

NumPy stretches the shapes to align properly and executes the addition efficiently. 

Real-World Applications of NumPy Broadcasting 

1. Speeding Up Machine Learning Workflows 

Broadcasting is heavily used in data normalization for training machine learning models. Instead of manually reshaping arrays, NumPy allows quick transformations: 

data = np.array([[50, 60, 70], [80, 90, 100]])  mean = np.mean(data, axis=0)  norm_data = (data - mean) / np.std(data, axis=0) 

This efficiently normalizes the dataset without unnecessary loops. 

2. Image Processing 

Broadcasting is widely applied in image manipulation, such as adjusting brightness levels across RGB channels: 

image = np.random.rand(256, 256, 3)  # A 256x256 RGB image  brightness = np.array([1.2, 1.1, 0.9])  adjusted_image = image * brightness 

Each colour channel is scaled independently, improving computational efficiency. 

3. Financial & Statistical Analysis 

In financial modeling, broadcasting simplifies calculations like percentage change computations: 

prices = np.array([100, 102, 105, 110])  returns = (prices[1:] - prices[:-1]) / prices[:-1] * 100 

This eliminates manual looping, making stock price analysis faster and more efficient.

So, on that note:

There's a bunch of things that seem kind-of like a Trace and a Determinant, in that there's a linear function F(.) that takes some kinda thing and returns a scalar, and then there's some other function that's exp( F ( log(.)))

Like if F is "the expectation of a random variable" E, then the Geometric Mean is exp ( E (log(.)))

And in quantum mechanics, with mixed states, the things people calculate from a density matrix ρ are the purity Tr(ρ^2) and the entropy -Tr( ρ log(ρ)) - which is almost a trace and determinant, but with F(A) = Tr(ρ A), applied to ρ itself.

So, are these all secretly the same thing? Is there some kind of matrix for which these things are traces and determinants?

[nhaneh]

forever annoyed that SSE2 doesn't have SIMD instructions for doing MULtiply and DIVide on 32-bit integers or almost any integers at all really

it kind of leaves me in a situation where I either hack together some nightmarish scalar solution to do my matrix transforms with fixed point, or just cave in and make the game/3D coordinate system use single precision floats and leave the conversion to fixed point for the tail end of the projection transformations since floats are kinda bad for screen coordinates and the blitting is mainly adding, subtracting, and bit manipulation like shifting.

What Is Neural Processing Unit NPU? How Does It Works

What is a Neural Processing Unit?

A Neural Processing Unit NPU mimics how the brain processes information. They excel at deep learning, machine learning, and AI neural networks.

NPUs are designed to speed up AI operations and workloads, such as computing neural network layers made up of scalar, vector, and tensor arithmetic, in contrast to general-purpose central processing units (CPUs) or graphics processing units (GPUs).

Often utilized in heterogeneous computing designs that integrate various processors (such as CPUs and GPUs), NPUs are often referred to as AI chips or AI accelerators. The majority of consumer applications, including laptops, smartphones, and mobile devices, integrate the NPU with other coprocessors on a single semiconductor microchip known as a system-on-chip (SoC). However, large data centers can use standalone NPUs connected straight to a system’s motherboard.

Manufacturers are able to provide on-device generative AI programs that can execute AI workloads, AI applications, and machine learning algorithms in real-time with comparatively low power consumption and high throughput by adding a dedicated NPU.

Key features of NPUs

Deep learning algorithms, speech recognition, natural language processing, photo and video processing, and object detection are just a few of the activities that Neural Processing Unit NPU excel at and that call for low-latency parallel computing.

The following are some of the main characteristics of NPUs:

Parallel processing: To solve problems while multitasking, NPUs can decompose more complex issues into smaller ones. As a result, the processor can execute several neural network operations at once.

Low precision arithmetic: To cut down on computing complexity and boost energy economy, NPUs frequently offer 8-bit (or less) operations.

High-bandwidth memory: To effectively complete AI processing tasks demanding big datasets, several NPUs have high-bandwidth memory on-chip.

Hardware acceleration: Systolic array topologies and enhanced tensor processing are two examples of the hardware acceleration approaches that have been incorporated as a result of advancements in NPU design.

How NPUs work

Neural Processing Unit NPU, which are based on the neural networks of the brain, function by mimicking the actions of human neurons and synapses at the circuit layer. This makes it possible to execute deep learning instruction sets, where a single command finishes processing a group of virtual neurons.

NPUs, in contrast to conventional processors, are not designed for exact calculations. Rather, NPUs are designed to solve problems and can get better over time by learning from various inputs and data kinds. AI systems with NPUs can produce personalized solutions more quickly and with less manual programming by utilizing machine learning.

One notable aspect of Neural Processing Unit NPU is their improved parallel processing capabilities, which allow them to speed up AI processes by relieving high-capacity cores of the burden of handling many jobs. Specific modules for decompression, activation functions, 2D data operations, and multiplication and addition are all included in an NPU. Calculating matrix multiplication and addition, convolution, dot product, and other operations pertinent to the processing of neural network applications are carried out by the dedicated multiplication and addition module.

An Neural Processing Unit NPU may be able to do a comparable function with just one instruction, whereas conventional processors need thousands to accomplish this kind of neuron processing. Synaptic weights, a fluid computational variable assigned to network nodes that signals the probability of a “correct” or “desired” output that can modify or “learn” over time, are another way that an NPU will merge computation and storage for increased operational efficiency.

Testing has revealed that some NPUs can outperform a comparable GPU by more than 100 times while using the same amount of power, even though NPU research is still ongoing.

Key advantages of NPUs

Traditional CPUs and GPUs are not intended to be replaced by Neural Processing Unit NPU. Nonetheless, an NPU’s architecture enhances both CPUs’ designs to offer unparalleled and more effective parallelism and machine learning. When paired with CPUs and GPUs, NPUs provide a number of significant benefits over conventional systems, including the ability to enhance general operations albeit they are most appropriate for specific general activities.

Among the main benefits are the following:

Parallel processing

As previously indicated, Neural Processing Unit NPU are able to decompose more complex issues into smaller ones in order to solve them while multitasking. The secret is that, even while GPUs are also very good at parallel processing, an NPU’s special design can outperform a comparable GPU while using less energy and taking up less space.

Enhanced efficiency

NPUs can carry out comparable parallel processing with significantly higher power efficiency than GPUs, which are frequently utilized for high-performance computing and artificial intelligence activities. NPUs provide a useful way to lower crucial power usage as AI and other high-performance computing grow more prevalent and energy-demanding.

Multimedia data processing in real time

Neural Processing Unit NPU are made to process and react more effectively to a greater variety of data inputs, such as speech, video, and graphics. When response time is crucial, augmented applications such as wearables, robotics, and Internet of Things (IoT) devices with NPUs can offer real-time feedback, lowering operational friction and offering crucial feedback and solutions.

Neural Processing Unit Price

Smartphone NPUs: Usually costing between $800 and $1,200 for high-end variants, these processors are built into smartphones.

Edge AI NPUs: Google Edge TPU and other standalone NPUs cost $50–$500.

Data Center NPUs: The NVIDIA H100 costs $5,000–$30,000.
