So according to the benchmarks somewhere in between Opus 4.7 and Mythos

GPT 5.4 is already better than Opus 4.7 to me. But, then again, Opus 4.7 is a massive disappointment. I hope they don't discontinue 4.6.

Depends in goals. For long free-firm discussions I find Opus 4.7 Adaptive better/deeper than Opus 4.6 Extended. But usual caveats apply: first week of use and token budget seems generous now on Max 5X.

I had the opposite experience. Opus 4.6 extended feels like the first genuinely intelligent model to converse with, Opus 4.7 adaptive feels like slightly smarter LinkedIn slop.

I’ve had great experience using opus 4.7 in cursor. Works for everything including iOS frontend

Cursor is what I daily-drive. 4.7 has been terrible for my mostly python-driven work (whereas Opus 4.6 was literally revolutionary to me). Our frontend folks are also complaining.
