Overview
- OpenAI began rolling out GPT-5.5 to ChatGPT Plus, Pro, Business and Enterprise users as well as Codex customers, while keeping the public API closed for now to finish safety checks with partners.
- The model is built to plan, use software tools, verify its own work and carry multi-step tasks to completion with less hand-holding from users.
- OpenAI reports strong benchmark results, including 84.9% on GDPval for autonomous knowledge work and 78.8% on OSWorld-Verified for operating real computer environments, with latency similar to GPT-5.4 and lower token use.
- OpenAI published new API rates for GPT-5.5 at $5 per million input tokens and $30 per million output tokens, roughly double the listed prices for GPT-5.4.
- GPT-5.5 powers new cloud “workspace agents” that keep working when users step away and share context across teams, pointing to a push toward a single, work-focused app in a crowded AI race with Anthropic and Google.
