Is the version number a retcon of 4.5? On OpenAI's models page the names appear completely reasonable [1]: The o1 and o3 reasoning models, and non-reasoning there is 3.5, 4, 4o and 4.1 (let's pretend 4o makes sense). But that is only reasonable as long as we pretend 4.5 never happened, which the models page apparently does

Hey OpenAI if you ever need a Version Engineer, I’m available.

  We will also begin deprecating GPT‑4.5 Preview in the API, as GPT‑4.1 offers improved or similar performance on many key capabilities at much lower cost and latency. GPT‑4.5 Preview will be turned off in three months

Here's something I just don't understand, how can ChatGPT 4.5 be worse than 4.1? Or the only thing bad is that the OpenAI naming ability?

The better the benchmarks, the worse the model is. Subjectively for me the more advanced models dont follow instructions, and are less capable of implementing features or building stuff. I could not tell a difference in blind testing SOTA models gemini, claude, openai, deepseek. There has been no major improvements in the LLM space since the original models gained popularity. Each release claims to be much better the last, and every time i have been disappointed and think this is worse.

First it was the models stopped putting in effort and felt lazy, tell it to do something and it will tell you to do it your self. Now its the opposite and the models go ham changing everything they see, instead of changing one line, SOTA models rather rewrite the whole project and still not fix the issue.

Two years back I totally thought these models are amazing. I always would test out the newest models and would get hyped up about it. Every problem i had i thought if i just prompt it differently I can get it to solve this. Often times i have spent hours prompting starting new chats, adding more context. Now i realize its kinda useless and its better to just accept the models where they are, rather then try and make them a one stop shop, or try to stretch capabilities.

I think this release I won’t even test it out, im not interested anymore. I’ll probably just continue using deepseek free, and gemini free. I canceled my openai subscription like 6 months ago, and canceled claude after 3.7 disappointment.

Excited to see 4.1 in the API. The Nano model pricing is comparable to Gemini Flash but not where we would like it to be: https://composableai.de/openai-veroeffentlicht-4-1-nano-als-...

Lots of improvements here (hopefully), but still no image generation updates, which is what I'm most eager for right now.

Big focus on coding. It feels like a defensive move against Claude (and more recently, Gemini Pro) which became very popular in that regime. I guess they recently figured out some ways to train the model for these "agentic" coding through RL or something - and the finding is too new to apply 4.5 on time.

I'm wondering if one of the big reasons that OpenAI is making gpt-4.5 deprecated is not only because it's not cost-effective to host but because they don't want their parent model being used to train competitors' models (like deepseek).

it's worse than 4.5 on nearly every benchmark. just an incremental improvement. AI is slowing down
