Physical Intelligence has launched a beta API that lets developers upload data, fine-tune the company's π0 and π0.5 robotic foundation models on managed compute, and access the resulting models through a hosted gateway for inference. The company says the system removes the need for developers to build their own ML infrastructure or data pipelines when adapting general-purpose robot models to new tasks, environments, or hardware. It is testing the API with partner companies across industries to gauge how broadly the models generalize.

404 Media reports that multiple contractors hired to improve OpenAI's models were terminated after being caught using AI tools to complete their training tasks, citing internal documents and interviews with contractors. One worker shared a termination letter citing concerns about the 'authenticity' of their work, while sources said such firings are common across a workforce of thousands. Two of the contractors worked through Mercor, a staffing firm reportedly in talks with Nvidia for a $20 billion valuation.

An independent researcher used supervised fine-tuning and agentic reinforcement learning to train a small 4B-parameter open-weights language model to generate PostgreSQL execution plans. On a set of 113 join-heavy queries, the tuned model cut latency by 44.7% on average compared to Postgres's default planner, even though the base model initially failed to produce valid plans for 99 of those queries. The project also involved building a custom measurement rig to reduce caching noise and a modified GRPO reinforcement learning method for scoring plans in a noisy environment.

OpenAI is temporarily lowering the price of its GPT-5.6-Sol model, with the discount running until at least November 21. Separately, the company is phasing out its fine-tuning platform, closing it to new users while letting existing customers keep submitting training jobs for a limited time. Models already fine-tuned will still work for inference until their underlying base models are retired.
