The Verge reported Thursday that OpenAI announced GPT-5.5, contextualising the release as arriving during an escalating rivalry with Anthropic and days before a federal trial pitting Elon Musk against OpenAI executives Sam Altman and Greg Brockman.
This article draws primarily on The Verge’s coverage. OpenAI’s primary announcement, which provides benchmark detail and early-tester accounts, is at openai.com/index/introducing-gpt-5-5.
OpenAI describes GPT-5.5 as its “smartest and most intuitive to use model yet, and the next step toward a new way of getting work done on a computer,” The Verge reported. The company says the model excels at writing and debugging code, online research, spreadsheets, and documents, and at work spanning multiple tools. According to The Verge, OpenAI said GPT-5.5 will have its “strongest set of safeguards to date” and can use “significantly fewer” tokens to complete tasks in Codex.
“Instead of carefully managing every step, you can give GPT-5.5 a messy, multi-part task and trust it to plan, use tools, check its work, navigate through ambiguity, and keep going,” The Verge quoted OpenAI as saying.
GPT-5.5 rolls out to Plus, Pro, Business, and Enterprise ChatGPT tiers and Codex, with GPT-5.5 Pro going to Pro, Business, and Enterprise users, The Verge reported.
The Verge positioned the release within the OpenAI-Anthropic competition. Anthropic recently released Claude Opus 4.7 and announced Mythos Preview, which Anthropic describes as a non-public model focused on cybersecurity. OpenAI followed with GPT-5.4-Cyber, its own model trained to flag cybersecurity vulnerabilities, according to The Verge. Both companies are competing for AI coding and enterprise business, with OpenAI having recently deprioritised certain features in favour of revenue drivers, The Verge reported.
The timing The Verge highlighted: GPT-5.5’s release comes days before proceedings in the Musk v. Altman case, set to begin Monday in a federal courtroom in Oakland, California.
