We found a way to scale humanoid control that reduces GPU-hours by more than 1000ร.
Across 129,514 motions, SuperMimic surpasses the state of the art (128 GPUs, 7 days) with 1 GPU in 3 hours.

1/9 Current optimizers are static during training. What if the optimizer could think and react while the network trains?
We let an agent watch the training dynamics and rewrite the optimizer's source code as training goes: a reactive optimizer.
In every language and image setting we tried that has no tuned recipe, it matches or beats the best recipe one can one-shot, and it guards against loss spikes and overfitting by itself. In the near future, optimization decisions may belong to agents, not humans.

For a while now, Kokoro has led in terms of naturalness with only 82M parameters. Weโre open sourcing 2x smaller models that score higher in naturalness, accuracy and come with voice cloning. The gap in naturalness is particularly striking beyond English as shown by the ELO scores below.
A new frontier for on-device speech.
We're open-sourcing Phonon, a suite of TTS models under 50m parameters, setting a new standard for naturalness and accuracy across languages, with the broadest inference support to date.
Phonon-31m is available under Apache 2.0.

Introducing REKI, a 2.4B vision-language-action model pretrained on public data only. With a simple design, it rivals larger models trained on in-house data with complex multi-stage pipelines, setting a new Pareto frontier between performance and size. kyutai.org/reki
Thereโs a new fairness issue I am seeing in public AI leaderboards.
Leaderboards that rank AI systems/models based on evaluations have become so high-profile that systems ranking near the top attract significant attention (and sometimes funding). This has led to silly games like benchmaxxing.
To counter this, modern leaderboards rank systems using a combination of public and private datasets, or entirely private datasets.
However, this shifts the power to leaderboard maintainers.
You could submit a system thatโs better than the current top-k systems, but youโre now at the mercy of the leaderboard maintainers to actually evaluate your system and add it to the rankings.
If leaderboard maintainers have incentives to favor the companies behind the current top-k systems, they can simply take their sweet time evaluating your submission, keeping the top-k rankings unchanged in the meantime.
This means you may never get a fair chance to compete on the leaderboard, regardless of how good your system is.
Iโm writing this from actual experience. I donโt want to name and shame the leaderboard maintainers involved because doing so would likely make things worse for me.

Can diffusion models generate high-quality images without CFG?
Yes! We introduce โจCorrection Training for Diffusion Modelsโจ, which significantly improves sample quality without relying on classifier-free guidance.

DAMNโฆ I tested Gemini 4 Argon on my CrusaderBench and it ranked 1st, beating Opus 5.5 by a margin.
Argon liked the benchmark too: โThis is one of the best-designed game benchmarks I have encounteredโ โบ๏ธ
the benchmark tests how well models can grow an economy in the strategic game Stronghold Crusader. it involves strategic reasoning, planning, computer use, and tool use.
other models need more reruns to filter out noise but so far:
> Opus is a very good strategic player
> Sonnet and Haiku were surprisingly lazy and uncompetitive, often sitting idle too soon before the time reached the end
> GPT models have been consistently good
> Kimi knew well how to utilize different buildings, but the strategy was often poor
> GLM 5.3 flash performed much better than I expected from it, much more competitive than Haiku
> Muse Wonder has been a very good player, though it performed worse than the do-nothing score in one of the maps, which tanked its overall score
> Argon on the other hand, pulled off some of the surprising tricks only pro players usually do, such as increasing the working population by building wells, or relying on bread to grow the economy.
the benchmark doesnโt tell the agents about any tricks, just the game rules. itโs completely up to the creativity of the models, and inferring from the game rules and resource prices to come up with a strategy.
the game is paused while models are thinking, so itโs purely a measure of strategy rather than model speed.
congrats to the @GoogleDeepMind @OfficialLoganK team for the model release.
all the game runs, logs, even screen recording of their playings, harness and benchmark code, prompts, etc are public on the website:
the next plan is to run models on more games, so the scores might change.
itโs in beta so things might go wrong ;)

Argon has this amazing natural understanding of the world. It can do so many things from first principles.
Here's a pelican riding a bike, using fourier epicycles.

Introducing GameGym: The ultimate gaming benchmark for AI agents ๐ฎ
Today we're releasing parts of our internal evaluation environments to track frontier model performance on video games.
It measures two main KPIs: completion rate and speed. Similar to speedrunning, while completion rates may eventually saturate, speed is designed to be an evergreen metric for continuously measuring improvements.
Games are amongst the hardest challenges for AI to master: 3D, real-time, long-horizon, non-deterministic and massively diverse environments.
We believe it is the perfect benchmark built for the endgame.
Check out early results here:

Backprop has been the only credit assignment algorithm capable of training large neural nets.
Introducing Dust, the first zeroth-order method to pretrain transformers to approach and sometimes even *exceed* backprop with large amounts of computation (bitter lesson!)
- Dust is on the order of 1,000 to 10,000x more compute efficient than EGGROLL, the state-of-the-art ES method, for training transformers.
- We chose pretraining transformers because it's arguably the hardest task possible for zeroth-order optimization.
- Search in high dimensions is really misunderstood: zeroth-order usually gets better with overparameterization, not worse, i.e. at a fixed population size, larger models (up to 120x) reach a lower loss than smaller ones.
- Backprop-like gradients emerge from a large population of activation perturbations, and the alignment holds up at every scale we tested, up to 1B tokens, which is critical for scaling.
The core idea is a *virtual population*, which helps scale to large populations in transformers by perturbing activations in parallel.
