Background & analysis
On November 10, 2026 at 10:52, a developer published an analysis of Anthropic's model tier selection guide on Juejin. The guide recommends running Opus 5.5 at the low tier first, then rerunning only failed cases at the high tier. Under this two-pass approach, the pass rate is around 97% and cost per question comes to roughly $0.17, which is above what is spent when everything is run at the high tier. The article additionally compares costs across the different tiers, looks at spending on Fable 5.2, and covers settings in Claude Code. It is worth noting that the share of failing prompts that still fail after the second pass, exact prices for each tier, and the release date of the original Anthropic guide are not specified; the only source available at this point is the single breakdown just published.
