Official announcement of GPT-5.5 release with detailed features and capabilities, indicating a significant update in AI technology.
OpenAI released GPT-5.5, its new frontier model for complex coding, computer use, knowledge work, and early scientific research, plus GPT-5.5 Pro for harder questions and higher-accuracy work, shipping with stronger safeguards and High capability treatment in Biological/Chemical and Cybersecurity under the Preparedness Framework
- Delivers a step up in agentic coding, computer use, knowledge work, and early scientific research, matches GPT-5.4 per-token latency, uses fewer tokens to complete the same Codex tasks, and reaches state-of-the-art results on Terminal-Bench 2.0, GDPval, OSWorld-Verified, and Tau2-bench Telecom, with strong gains on SWE-Bench Pro
- Rolling out to Plus, Pro, Business, and Enterprise users in ChatGPT with GPT-5.5 Pro for Pro, Business, and Enterprise tiers, available in Codex for Plus, Pro, Business, Enterprise, Edu, and Go plans with a 400K context window and a Fast mode at 1.5x speed for 2.5x cost
- API access coming soon at $5 per 1M input and $30 per 1M output tokens for gpt-5.5 and $30 per 1M input and $180 per 1M output tokens for gpt-5.5-pro, both with a 1M context window, Batch and Flex at half the standard rate, Priority at 2.5x
- OpenAI also launched a Bio Bug Bounty scoped to GPT-5.5 in Codex Desktop only, offering $25,000 for the first universal jailbreak that clears all five bio safety questions from a clean chat without prompting moderation, under NDA
I have been focusing more on infrastructure and DevOps work recently, and after testing GPT-5.5 on xhigh in Codex for a while now it handles everything I give it, the only limitation is the speed of my reviews and my available time
