dejavucoder · x · 2026-07-25
The shared testing charts illustrate Claude Opus 5's performance on the FrontierCode benchmark. Data reveals that "medium thinking" is the sweet spot for Opus 5, outperforming other settings by a massive margin in coding capabilities. Interestingly, "extra-high thinking" performs similarly to "low thinking". The author jokingly notes that Opus 5, much like humans, operates best in a flow state and burns out when overthinking.
