Claude Opus 4 has become part of my daily workflow. The reasoning is sharp, the writing is clean, and it rarely loses the thread on long prompts. Worth every penny.

Decent, hit or miss

Works well for drafting, less so for math or precise dates. Good tool overall, just don't trust it blindly. Cautiously recommended.

Decent, hit or miss

It's a useful assistant. The rate limits and occasional refusals are annoying, but the core quality is there. Your mileage may vary.
