A researcher says Opus 5 is a strong research peer but still too cautious for coding
_xjdr · x · 2026-07-26
A researcher says Opus 5 feels like an excellent peer for rigorous research, but not necessarily the most charming one.
- The model is described as pragmatic, abrupt, and a bit too cautious, apparently tuned heavily against reviewer-2 style criticism.
- For coding, the poster still prefers Sol High as a daily driver, Sol Ultra for deep technical problems, and Sol Pro as a peer reviewer.
- Opus 5 nevertheless earns a place in the toolbox because it works well as a research collaborator.
