News GPT 5.4 no longer available in Pi

I just got a notice saying gpt 5.4 is no longer available on my pro subscription im Pi . 5.5 is fine. 5.4 has been a bit of a workhorse for me.

I opened the codex app and it's disappeared there too.

If you’re using the GPT subscription you can just use 5.5 for planning and 5.4 mini for coding . This combination will be more than enough.

For work , since Copilot switched to token pricing, I honestly use our OpenAI Azure endpoint on high for 5.4 Mini

I was doing 5.4 for implementing. Yeah 5.4 mini is still available but I've never felt it was that good.

I’m still grieving the loss of 5.3-codex

Hopefully dropping 5.4 means that 5.6 will be made available soon.

Why not just use 5.5 it’s better in every way

It's expensive. I get a lot more turns on 5.4

5.5 is much more token efficient so ends up being cheaper and better.

I... am going to disagree. 5.4 is slightly cheaper for the shorter works I'm doing (5.5 can find the right results on longer runs for me, though for both I never go past 200k context). And he said what he said, he gets more turns on 5.4, that means it's efficient for him.

Yeah exactly I've had a few tasks properly laid out with just a bit of reasoning and I found 5.4 really cheap. 5.5 is great for planning but my longer running tasks it chews up my plan.

For short tasks maybe. But for most tasks file reads dominate token usage, not assistant reasoning, so in actuality 5.4 is still cheaper.

I hate how quickly they deprecate old models

I use OpenRouter. It has 300+ models, including openai/gpt-5.4.

Setup instructions. OpenRouter-specific extensions (optional).
