You can’t make up your mind about a model by using it on one task. Especially to say it’s such a bad downgrade after that is ludicrous. I’ve had great experiences with it this morning.

That was more than one task. It was 3.

I also had Opus 4.7 and Opus 4.6 do audits of a very long document using identical prompts. I then had Codex 5.4 compare the audits. Codex found that 4.6 did a far better job and 4.7 had missed things and added spurious information.

I then asked a new session of Opus 4.7 if it agreed or disagreed with the Codex audit and it agreed with it.

I also agreed with it.

It's been dramatically better than any model I have ever used before on my tasks.
