gpt-5 is the best coding model in the world and is now the default in @cursor_ai. youtube.com/watch?v=PQUcIb…
The wait is over! As the leading AI code review tool, CodeRabbit was given early access to OpenAI's GPT-5 model to evaluate the LLM's ability to reason through and find errors in complex codebases! Our evals found GPT-5 performed up to 190% better than other leading models!
I’ve been using gpt-5 for a bit now. This model broke me. It is so good. I didn’t know what the price was. I assumed it would be o3-pro priced because it is that smart. Nope. Truly insane. Videos coming very soon.
These models are amazing!
gpt-oss is out! we made an open model that performs at the level of o4-mini and runs on a high-end laptop (WTF!!) (and a smaller one that runs on a phone). super proud of the team; big triumph of technology.
We achieved gold medal level performance on this year's IMO! Our model thinks and writes proofs in clear, plain‑English - no formal code required. Unlike the narrower systems used in past competitions, our model is built to reason broadly, far beyond contest problems.

1/N I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).
My happy place

Great day to be a Plus user.
GPT-4.5 is singularly leading on the Style Control leaderboard, showing its strength in both style and substance.
GPT-4.5 topped all categories across the board, with a clear leadership in Multi-Turn. 🥇 Multi-Turn 💠 Hard Prompts 💠 Coding 💠 Math 💠 Creative Writing 💠 Instruction Following 💠 Longer Query
I had early access to GPT-4.5. I found it to be by far the highest verbal intelligence model I've ever used. It's an outstanding writer and conversationalist, and excels at what I call "concretizing vibes": things like recommending a particular list of movies or songs for a very…
Last week, @OpenAI asked me if I'd like to alpha test GPT 4.5 Honored to be chosen, I'm going to share some visual comparisons to their older models below.
Just an FYI: I was an early tester of GPT-4.5. Whatever the benchmarks say *do not* tell the whole story. Big model smell is there…
i've been testing gpt 4.5 for the past few weeks. it's the first model that can actually write. this is literally the midjourney-moment for writing. (comparison to gpt 4o below)
welcome, gpt-4.5 i've spent a lot of time playing with this model recently, and it's left me feeling the agi some thoughts
