GOOGLE'S NEW CHIP FOR GEMINI

Google reportedly developed a server chip called Frozen v2 for a potential 2028 release, targeting six to ten times more tokens per unit of power than its existing AI hardware. The project reflected a broader push to reduce inference costs and reliance on Nvidia.

SPARSE BY DESIGN

Kimi K3 activates 16 of 896 experts per token. While the total parameters have grown, the active parameters have barely grown at all over the past three releases. The strategy appears to be to keep per-token compute roughly flat while relentlessly inflating total capacity. At a fixed training compute budget, more experts means lower loss, and the model learns more from the same FLOPs. The open source labs have discovered that the cheapest way to buy intelligence is to spend capacity.

ON KIMI K3: ITS CAPABILITIES AND RELATED DISCONTENTS

Kimi K3 is a very good model with excellent benchmarks. It is the largest (soon-to-be) open model so far, at 2.8T parameters, which explains many of its gains. The model is somewhat distilled, and its performance looks jagged, but it will likely fit well into many workflows. At the current rate of development, China appears capable of releasing a Mythos-level open model by the end of the year.

INTRODUCING COSMOS 3 EDGE

NVIDIA Cosmos 3 Edge is a 4-billion-parameter open world model that helps robots and vision AI agents understand their surroundings, reason in real time, and generate robot actions on edge devices. It is now available on Hugging Face. The model delivers memory-efficient, high-throughput inference across NVIDIA edge computers. It connects understanding, prediction, simulation, and action through a shared world representation. The model can be used as a reasoner or an action generator.

XIAOMI-ROBOTICS-1

Xiaomi-Robotics-1 is a ready-to-use robot foundation model trained on over 100K hours of real-world manipulation trajectories. It combines large-scale embodiment-free pre-training with a modest amount of real-robot data in a post-training stage. It serves as a strong robot foundation model for downstream applications and can learn new tasks with high data efficiency. Footage of robots operating on the model performing household tasks is available in the post.

LANGUAGE MODEL HARNESSES ARE COMPOSITIONAL GENERALIZERS

Scaling data will remain the biggest driver of progress. The machine that we feed that data into and its inductive biases are what will determine the coefficients of that scaling. Better returns on scaling require compositional generalization. The capacity for compositional generalization seems to largely live in harnesses.

WHY YOUR AI BILL WENT UP EVEN THOUGH TOKEN PRICES ARE FALLING

Token prices dropped significantly, yet many enterprises exceed AI budgets. A unit of inference cost $60 per million tokens in 2020, now just pennies. The discrepancy suggests inefficiencies despite lower token costs.
