The newsletter for ai builders of all levels. Mini-tutorials, tool reviews, and lay of the land from an exited founder turned investor and forever tinkerer.
Hey folks,

Multiple new launches are possible this week. The rumourland’s buzzing that openai’s open-weight model is likely going to come in two sizes, 20b and 120b. Plus, expect news about opus 4.1, gpt-5 and new gemini stuff this week.
In the meantime, Google quietly dropped Gemini 2.5 Deep Think126. You can only get it if you pay $250/mo for the Gemini Ultra plan, so I haven’t tried it yet. I read Shawn’s post169 that Deep Think’s performance improvement over the base 2.5 Pro seems much larger than o3 Pro’s improvement over base o3.
Google is launching a Game Arena183 (RL environments) via Kaggle to pit models against each other in games, starting with chess. These environments are designed for the models to use text representation of chess moves and test their logical reasoning (instead of just using a code library for predicting chess moves).
