OpenAI released GPT-6.1 Sol on September 29, pricing the model at $2 per million input tokens and $10 per million output tokens through its API. The company positions the model between its existing GPT-6 Sol and flagship GPT-6 Astra. OpenAI says the new version approaches Astra on coding, computer-use and professional-work evaluations while charging one-fifth of Astra’s standard input and output prices. Why it matters: Developers running agents repeatedly pay for long prompts, tool results and generated output. A lower price at near-flagship capability can change which model they leave active for routine work and which tasks still justify Astra. ...

PostHog released a reasoning-based decision model while OpenAI expanded its developer, pricing and enterprise-distribution offers. Community discussions focused on privacy measurements, data-centre economics and possible restrictions on Chinese open weights. » Why it matters: The day’s lower-ranked releases and discussions show where AI products are being packaged for routine work—and where users still lack independent evidence about performance, privacy and cost. In brief PostHog adds reasoning to a decision model. Jeeves is a 9-billion-parameter, Jev-compatible model that answers yes-or-no, multiple-choice and rating questions after an optional reasoning stage. PostHog released weights, code and data and reports stronger results than Jev on selected public tests; those results remain developer-run. It is worth watching because it combines a constrained decision interface with a slower reasoning path instead of sending every classification task to a general chatbot. Source ...
