Maia 200: make data movement programmable
Microsoft's accelerator paper starts with a practical problem: a chip can perform many calculations yet still sit idle waiting for data. Maia explicitly programs how data moves through specialized memories and processing engines. The aim is to keep inference hardware productive while reducing the cost of moving information.

Original paper: Maia 200: A Software Defined Dataflow System for Large-scale AI Acceleration
- Introduces a software-defined dataflow architecture that coordinates memory and computation explicitly.
- Describes low-precision inference hardware with high-bandwidth memory and large-scale parallelism.
Where the result may not travel
Architecture specifications and vendor-reported efficiency do not establish broad customer adoption or matched-workload total cost against competing platforms.
Evidence to watch
Compare accepted tasks per dollar, utilization and porting effort on the same model. Track deployment scale rather than peak FLOPS alone.

Google TPU: five generations of scale
Google reviews five TPU generations to explain how a relatively stable chip architecture can scale into much larger training systems. The paper treats memory, communication, fault recovery and power efficiency as part of the product, rather than judging an accelerator only by its calculation speed.

Original paper: Google's Training Supercomputers from TPU v2 to Ironwood: Architectural Stability, Scale, Resilience, Power Efficiency, and Sustainability Across Five Generations
- Documents improvements in memory capacity, bandwidth and system scale across successive TPU generations.
- Explains how optical circuit switching and fault-recovery mechanisms support useful work at large scale.
Where the result may not travel
This is a Google-authored history of its own systems. Cross-generation improvements do not prove superior customer economics against every current GPU workload.

OpenRouter: where the tokens actually go
This study uses real interactions routed through OpenRouter to examine AI usage across models, tasks, places and time. It shifts the question from which model wins a test to where developers and users choose to send work. That is useful for testing whether better capability becomes recurring demand.
Read original paper ↗INVESTMENT TRANSMISSIONInference / cloud Demand validationPersistent paid workload growth could offset falling token prices; volume alone cannot establish this offset.

Original paper: State of AI: An Empirical 100 Trillion Token Study with OpenRouter
- Analyzes more than 100 trillion tokens of interactions on one multi-model inference platform.
- Studies usage patterns during the move toward reasoning models and multi-step inference.
Where the result may not travel
OpenRouter users are a selected population. Token volume is not revenue, profit, active users or the entire AI market; free traffic and differing tokenizers complicate comparisons.
Evidence to watch
Track comparable routed token volume alongside price, paid retention and workload mix. Do not turn developer nationality into user geography.

METR: how long can an agent work?
METR measures task difficulty in a familiar unit: the time a skilled person typically needs. Its 50% completion horizon describes tasks an AI can finish half the time. This makes progress easier to interpret, while exposing the gap between a convincing short demo and reliable autonomous work.

Original paper: Measuring AI Ability to Complete Long Software Tasks
- Combines human task timings with model success rates across software and reasoning tasks.
- Documents historical growth in the measured horizon and discusses limits to extrapolating that trend.
Where the result may not travel
A 50% success threshold is not production reliability. The task sample, scaffolding and human baselines constrain generalization to jobs and company-wide productivity.
Evidence to watch
Monitor high-reliability success thresholds, human review time and cost per accepted task, not just the longest demonstrated task.

DeepSeek-R1: learning to reason
DeepSeek shows how reinforcement learning can encourage a model to check its work and change strategy on problems with verifiable answers. It also transfers reasoning behavior into smaller models. The investment question is whether extra computation at inference produces enough useful work to justify its cost.
Read original paper ↗INVESTMENT TRANSMISSIONInference compute More work per requestReasoning may increase tokens and server time per query; smaller models and better accuracy can offset the cost.

Original paper: DeepSeek-R1: Incentivizing Reasoning Capability in LLMs via Reinforcement Learning
- Reports emergent reasoning behavior from reinforcement learning without relying on human-written reasoning traces at every step.
- Shows that large-model reasoning can help train smaller models through distillation.
Where the result may not travel
Strong math and coding results do not establish reliability in open-ended business tasks. Smaller distilled models can lose capability, and longer reasoning can increase latency and token costs.
Evidence to watch
Measure success-adjusted cost and latency under a fixed task budget. More tokens are valuable only when they improve accepted outcomes.

DeepSeek-V3: doing more with less compute
V3 uses a mixture of experts so each token activates only part of a large model. It combines that approach with compressed attention memory and low-precision training. The central idea is to make each unit of useful computation cheaper through coordinated model and systems design.
Read original paper ↗INVESTMENT TRANSMISSIONCompute / cloud Lower unit cost; demand uncertainCheaper useful inference can pressure price per token while making more applications economic. Total accelerator demand depends on the demand response.
NVDA · AMZN · GOOGL Memory / networking Different bottleneck mixExpert routing and large model weights can preserve memory and communication constraints despite lower active arithmetic.

Original paper: DeepSeek-V3 Technical Report
- Reports 671 billion total parameters with 37 billion activated per token.
- Combines Multi-head Latent Attention, expert routing and FP8 training to improve computational efficiency.
Where the result may not travel
Reported training compute is not a complete corporate R&D budget. Sparse activation does not eliminate the need to store model weights, move data or coordinate expert servers.
Evidence to watch
Compare utilization, interconnect traffic and total cost at matched output quality; avoid interpreting a single training bill as an industry spending forecast.

Test-time compute: when thinking longer pays
Instead of using the same inference effort on every question, this paper asks when a model should spend more time revising or searching for an answer. Its key point is that the best use of extra compute depends on the difficulty of the problem and the method used to check candidate answers.
Read original paper ↗INVESTMENT TRANSMISSIONInference / cloud Variable resource intensityHard tasks can become more compute-intensive while easy tasks are routed cheaply, changing capacity planning and pricing.

Original paper: Scaling LLM Test-Time Compute Optimally can be More Effective than Scaling Model Parameters
- Compares approaches for allocating additional computation when answering a prompt.
- Finds that adapting the strategy to prompt difficulty can use the compute budget more effectively than a uniform sampling baseline.
Where the result may not travel
The result is task- and verifier-dependent. Extra search cannot always compensate for missing knowledge or weak evaluation, and end-user latency may limit adoption.
Evidence to watch
Track quality at a fixed total budget, including verifier and retry costs, and distinguish latency-sensitive products from offline work.

FlashAttention-3: keep the GPU working
The attention step in a language model moves large amounts of information between memory and calculation units. FlashAttention-3 overlaps those operations and uses Hopper hardware features more effectively. It demonstrates how software can extract more useful performance from an already-installed accelerator.
Read original paper ↗INVESTMENT TRANSMISSIONGPU / cloud More output per installed chipBetter utilization can reduce required GPUs for a fixed workload or enable more demand at a lower price; the net hardware effect is conditional.

Original paper: FlashAttention-3: Fast and Accurate Attention with Asynchrony and Low-precision
- Uses asynchronous execution and low-precision techniques to improve attention-kernel utilization on H100 GPUs.
- Reports gains against earlier attention implementations under the paper's hardware and workload settings.
Where the result may not travel
An attention-kernel speedup is not the same as the speedup of a complete application. Benefits vary with sequence length, batch size, numerical format and other bottlenecks.
Evidence to watch
Benchmark complete inference and training jobs, measuring tokens per second, latency and power at matched quality rather than copying kernel headline gains.

Mamba: a different way to remember
Mamba explores an alternative to storing and attending over every earlier token. It maintains a compact state that selectively updates as new information arrives. The architecture targets long sequences with more favorable computational scaling while trying to preserve the ability to use relevant content.
Read original paper ↗INVESTMENT TRANSMISSIONMemory / compute Possible intensity changeIf adopted at comparable quality, recurrent or hybrid designs can change the balance between cache memory, arithmetic and bandwidth per token.
MU · NVDA · AMD Cloud / applications New feasible workloadsCheaper long-sequence processing could expand document, audio and other streaming applications; commercial demand still needs validation.

Original paper: Mamba: Linear-Time Sequence Modeling with Selective State Spaces
- Introduces input-dependent selection within a state-space sequence model.
- Pairs the architecture with a hardware-aware implementation to process long sequences efficiently.
Where the result may not travel
Efficient scaling does not guarantee equal retrieval or reasoning quality on every task. Results for the studied models do not establish wholesale replacement of Transformers.
Evidence to watch
Compare long-context retrieval accuracy and total serving cost with current Transformer and hybrid systems on the same workload.

PagedAttention: fit more work into memory
When many people use a language model together, each request needs a growing memory of earlier tokens. PagedAttention manages that memory in smaller blocks, similar to virtual memory in an operating system. The vLLM serving system uses this approach to fit more useful work into the same hardware.
Read original paper ↗INVESTMENT TRANSMISSIONInference / cloud Lower serving costMore concurrent requests per device can improve provider margins or be passed through as lower API prices.
AMZN · MSFT · GOOGL Memory / accelerators Demand response uncertainA fixed workload can need fewer devices, while cheaper access can expand usage. Hardware spending follows the combined effect.

Original paper: Efficient Memory Management for Large Language Model Serving with PagedAttention
- Reduces wasted key-value cache space and supports sharing cache blocks where appropriate.
- Demonstrates higher serving throughput than the comparison systems at comparable latency in the paper's experiments.
Where the result may not travel
The paper's 2023 baselines are historical. Actual gains depend on workload, scheduling, context length and hardware; eliminating fragmentation does not eliminate memory demand.
Evidence to watch
Measure sustained throughput under a latency service-level objective, including realistic request lengths, and track whether savings become margin or price cuts.
