A benchmark screenshot claims Claude Opus 5 is the best default choice for FrontierCode at medium reasoning settings.
- On the leaderboard shown in the image, Fable 5 leads the overall ranking, but Opus 5 is close behind at medium reasoning.
- The image and caption argue that default Opus 5 → Medium gives the best practical tradeoff.
- The post frames this as a useful “alpha” for coding-agent workflows rather than a general model ranking.
