Consistently useful

Claude Opus 4 is fast and accurate for most of what I throw at it. Brainstorming, refactoring, summarizing dense docs — it just works. Worth every penny.

Handles complex prompts well

For research and long-form writing Claude Opus 4 is excellent. Context handling is strong and the answers feel thought-through, not generic. Would recommend to a colleague.

My daily driver for writing

I use Claude Opus 4 for drafting, summarizing, and debugging. It nails tone and gives well-structured answers. Occasional slips but nothing serious.

Useful, still hallucinates

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