- GPT-5-Codex promises greater performance and successful rates
- It is included for Plus, Pro, Business, Edu and Enterprise users
- The model can use 93.7% less tokens in light tasks
Operai has shared more details about GPT-5-Codex, an specially designed version of GPT-5 specifically optimized for the coding of agent and software engineering of the real world, and we are in a pleasure when it comes to reliability and performance.
The Chatgpt manufacturer affirmed a Swe-Bench verified reference rate of 74.5%, with a refactorization performance improving 51.3% (compared to 33.9% in GPT-5).
Like GPT-5, GPT-5-Codex will dynamically adjust the reasoning time for faster performance in small tasks and a more complete reasoning in the complexes, and has already been tested working independently for more than seven hours in large refractors.
GPT-5-Codex is a great update
Operai says that GPT-5-Codex is strong in code reviews, capturing critical errors before launch, but can also handle the border work with visual inspection, screenshots and improvements in mobile web design.
The news occurs only a couple of months after Operai launched Codex Cli (in April) and Codex Web (in May), before combining them in a “unified experience … connected by … Chatgpt” at the beginning of September.
It is included with Chatgpt Plus, Pro, Business, Edu and Enterprise plans, and works at terminal, IDES, on the web, in Github and the iOS application.
The company also detailed how GPT-5-Codex uses 93.7% less tokens than GPT-5 in light interactions, but will also spend twice as much reasoning, editing, testing and it is necessary if necessary.
Equally important for developers, the tool will provide records, appointments and test results for transparency. Developers used Codex Cli through the API key will also get access to API to GPT-5-Codex “soon.”
“Codex is becoming the coding partner that we have always imagined, a faster, more reliable and deeply integrated in the tools it already uses,” Openii wrote.
In addition, Edu and Business plans have enough to cover “some coding sessions focused every week”: users who need more should update Pro for “a complete work week in multiple projects.” Business accounts pay what they use through a shared credit group.
