Overview
- OpenAI launched the GPT‑5.6 model family and the ChatGPT Work agent on Thursday, making desktop access broadly available and phasing web and mobile access to paid tiers first.
- The GPT‑5.6 family includes Sol as the flagship for the hardest tasks, Terra as a balanced option, and Luna as a fast, low‑cost choice with token pricing published for each model.
- ChatGPT Work combines ChatGPT and Codex to pull context from connected apps and files, execute multi‑step workflows, and produce finished deliverables such as documents, spreadsheets, presentations, and web apps.
- OpenAI said the rollout followed a government review, includes layered safeguards and red‑teaming, and will gate the most cyber‑capable features behind Trusted Access for Cyber and hardware‑backed passkey requirements.
- The company is pitching Sol’s benchmark and efficiency gains as a way to undercut rivals like Anthropic on cost and speed, a move that could cut running costs for enterprises and shift how teams use AI for production work.
