@AIatMeta says it is releasing Muse Spark Open, which it calls “the most capable US open-weight model to date.” The quoted post says the model is built for coding and agentic work and lists 816B total and 42B active parameters, plus a 1M token [context window](https://t.co/yAtoxNeYJm). Nathan Lambert reacts: “Okay now I really gotta blog 🎉” https://t.co/uKl5X18Xpw
Ethan Mollick says Gemini 4 is a big improvement over earlier Gemini models and the first non-OpenAI or Anthropic model to pass the Fable/Mythos/Astra bar. He finds it more pleasant and agentic, with a distinct personality, while noting that it lags in complex multi-agent work and can be overly certain and lazy. His post also links to three city-builder demos.
François Chollet congratulates the release, saying Gemini 4 Argon looks like a fantastic model. In the quoted announcement, Sundar Pichai says it is available globally today for developers and enterprises in the paid tier of the Gemini API and the Gemini platform, for Ultra subscribers in Google Antigravity, and for Ultra and Pro subscribers in the Gemini app and Search.

muse wonder over a cheeky pint at some point in this video i get my annual performance review live on camera -- a truly tender moment 🥹
Had some early access to Muse Wonder, but did not get a chance to use it a ton. From limited testing, it seems like a good model. Perhaps more impressive is the progress since April on my drowned neogothic city twigl shader test. Very fast progress from Meta in a short time.
🍉 MUSE WONDER 🍉 @hdubugras says Alex and Meta are on a roll, and that the model has replaced Astra/Opus in a variety of their workflows. They say it handles day-to-day tasks efficiently and quickly, and offer congratulations. Alexandr Wang’s reaction: “🍉 MUSE WONDER 🍉”
If you announce a model's benchmarks without releasing it (weights, product, api, etc "later"), feels like almost a sure thing that someone releases a better model in your category before you get it out.
Nano Banana announced Nano Banana 2.1, claiming improvements over its previous models across the board, including visual design, mask-based editing, subject consistency, and more natural-looking imagery. It is available in @GeminiApp, @GoogleAIStudio, and more. Josh Woodward commented, “Mask-based editing is my favorite from today, much more coming soon!” https://twitter.com/NanoBanana/status/2107521202466046453
Why it matters: The announcement frames the upgrade around visual design, editing, subject consistency, and natural appearance, providing a concrete comparison with previous models.
Mistral AI announced Mistral Large 4, aka Le Chonk, with 1T parameters, 49B active, and native multimodality, available via API today with an open weights release planned for the end of October. It claims the model leads open weights models from the US or Europe on aggregated benchmarks and surpasses closed frontier models on visual grounding. Arthur Mensch adds that it took groundwork, was trained and served on their own compute, and that RL shows no sign of saturation.
Why it matters: The announced API availability and end of October open weights release give teams distinct timelines for accessing the model through hosted infrastructure or its weights.
