Introducing GPT-5 | OpenAI
GPT‑5 not only outperforms previous models on benchmarks and answers questions more quickly, but—most importantly—is more useful for real-world queries. We’ve made significant advances in reducing hallucinations, improving instruction following, and minimizing sycophancy, while leveling up GPT‑5’s performance in three of ChatGPT’s most common uses: writing, coding, and health.

What is the difference between GPT-5 and GPT-5-chat exactly? Why does GPT-5-chat rate so poorly on livebench.ai?
gpt5-chat is basically a highly distilled non-thinking version of gpt5, so it's its own model. it's the reason so many people don't like gpt5 compared to 4o because its roughly on the same intelligence level but much less empathetic and sycophantic (also faster, so likely quantized or just smaller). gpt5-pro is gpt5 with parallel test time compute. how exactly that is implemented is not public knowledge AFAIK but think of it as several gpt5 instances discussing among each other what the best solution is. it's likely the absolute best model available atm.

ChatGPT's GPT-5.2 is here, and it feels rushed
Like its predecessor, it includes two default variants. GPT-5.2 Instant is designed for everyday chatting and web searches. GPT-5.2 Thinking is meant for more complex tasks like long reasoning chains and multi-step problem solving.

August 19, 2025 -
I had the impression that GPT-5-chat was simply a sort of a wrapper that directed prompts to the appropriate level of GPT-5 (per thinking level, or to GPT-5-mini when the user had used up their quota for regular GPT-5).
But according to livebench.ai, GPT-5-chat is much worse than GPT-5 with low thinking and even GPT-5 mini. It's basically at the level of GPT-5-nano, but it is not GPT-5-nano.
What the fuck is GPT-5-chat exactly then?
And while I'm here, what exactly is GPT-5-pro? GPT-5 with high thinking effort?

GPT-5-chat uses the GPT-5 model used in the ChatGPT web interface, which is a non-thinking model called GPT-5-main. The GPT-5 models in the API are actually called GPT-5-thinking. GPT-5-chat scores less in LiveBench because in the model family hierarchy, GPT-5-main is equivalent to GPT-4o and GPT-5-thinking is equivalent to o3. In LiveBench, compare the scores for GPT-4o and o3 and you will see a similar difference in scores.

GPT-5: It Just Does Stuff - by Ethan Mollick
August 7, 2025 - So OpenAI previously made the default ChatGPT use fast, dumb models, hiding the good stuff from most users. A surprising number of people have never seen what AI can actually do because they're stuck on GPT-4o, and don’t know which of the confusingly-named models are better. GPT-5 does away with this by selecting models for you, automatically.

> GPT5 is about lowering costs for OpenAI, not pushing the boundaries of the fronteir It's literally a repainted 4o + o3. Knowledge cutoff is 2024. Voice mode is the exact same. Image generation is the exact same. Plus (pun intended), they got rid of ALL other models, so good luck if you hit usage limits.

August 11, 2025 - So GPT-5 came out, and with it 4 models in the API. I am desperately trying to find information about GPT-5 Chat, but I can not. What’s the difference between GPT-5 and GPT-5 Chat? Does the chat version have reasoning? When I look at the OpenAI description, it says that it does, but when I use it, no matter how I prompt it, it does not seem to take any time to reason, and setting a reasoning_effort parameter doesn’t work on it like it does on GPT-5.
