GPT-4o got another update in ChatGPT. This is a somewhat frustrating way to announce a new model. @OpenAI on Twitter just now:
GPT-4o got an another update in ChatGPT!
What's different?
- Better at following detailed instructions, especially prompts containing multiple requests
- Improved capability to tackle complex technical and coding problems
- Improved intuition and creativity
- Fewer emojis 🙃
This sounds like a significant upgrade to GPT-4o, albeit one where the release notes are limited to a single tweet.
ChatGPT-4o-latest (2025-0-26) just hit second place on the LM Arena leaderboard, behind only Gemini 2.5, so this really is an update worth knowing about.
The @OpenAIDevelopers account confirmed that this is also now available in their API:
chatgpt-4o-latestis now updated in the API, but stay tuned—we plan to bring these improvements to a dated model in the API in the coming weeks.
I wrote about chatgpt-4o-latest last month - it's a model alias in the OpenAI API which provides access to the model used for ChatGPT, available since August 2024. It's priced at $5/million input and $15/million output - a step up from regular GPT-4o's $2.50/$10.
I'm glad they're going to make these changes available as a dated model release - the chatgpt-4o-latest alias is risky to build software against due to its tendency to change without warning.
A more appropriate place for this announcement would be the OpenAI Platform Changelog, but that's not had an update since the release of their new audio models on March 20th.
