OpenAI just introduced GPT-5.5
OpenAI has officially launched GPT-5.5, calling it their smartest and most intuitive model yet.
According to the announcement, GPT-5.5 is built for practical, high-value work like:
- coding
- online research
- data analysis
- document and spreadsheet creation
- multi-step tool use on a computer
Some of the biggest improvements they highlighted are in:
- agentic coding
- knowledge work
- computer use
- early scientific research
OpenAI also says GPT-5.5 keeps GPT-5.4-level speed while improving performance, and in some coding tasks, it can use fewer tokens.
A few benchmark numbers they shared:
- 82.7% on Terminal-Bench 2.0
- 73.1% on Expert-SWE
- 84.9% on GDPval
- 78.7% on OSWorld-Verified
They also mentioned GPT-5.5 Pro, which scores even higher on some harder evaluations.
Availability
- GPT-5.5 is rolling out to Plus, Pro, Business, and Enterprise users in ChatGPT and Codex.
- GPT-5.5 Pro is rolling out to Pro, Business, and Enterprise users.
- API access is said to be coming soon.
OpenAI also says the model went through extensive safety testing, red teaming, and feedback from nearly 200 trusted early-access partners before release.
Honestly, this looks like a serious step forward for people who use AI for actual work, not just casual chat.
What do you think — real upgrade, or just another benchmark-heavy release?
