Model insights
- 01 The weakest Opus: same $5/$25 price as opus-4-8 but 4.5 points less accurate, with a heavy "optimistic" tilt (17 under vs 1 over) and false "safe" calls on 2026-02-18, 02-25 and 07-05.
- 02 Its misses cluster in the Feb-Mar stretch where it kept answering "low" against a "medium" consensus.
