I thought I’d try Composer 1.5, after an amazing week with Opus 4.6.
I loved Composer 1 - the fast/accuracy balance was superb.
The pattern with 1.5 is:
Me - “do a thing”
Composer 1.5 - “here’s how to do the thing”
Such a shame; the harness seems to be off, making it ‘lazy’ (like when we initially had GPT5-Codex).
