I'd argue that for whatever other faults they have, Composer 2.5 is pretty competitive as an implement-planned-work model. It's several times faster than Sonnet 5, cheaper, and performance is comparable.

Ears wide open for a model that does better for the same parameters. Pareto efficiency is important, but Anthropic doesn't seem to care about it. They desperately need a Haiku 5, IMO.
