What the Benchmarks Tell Us
Banc SWE Vérifié is like a test where the AI has to fix real problems from GitHub (a website where people store code). Sonnet 4.6 got 79.6%, and Opus 4.6 got 80.8%. The difference is very small, so both are excellent at coding. For comparison, older versions scored like this: Sonnet 4.5 was 77.2%, and Opus 4.5 was 80.9%. That means Sonnet 4.6 has improved a lot and is now very close to Opus.
GPQA Diamond is a very hard test with science questions (physics, chemistry, biology) at a graduate level. Here the difference is big: Opus 4.6’s 91.3% vs Sonnet 4.6’s 74.1% represents a 17-point chasm — the single largest performance difference between the two models. So if you need the AI to solve very difficult science or deep thinking questions, Opus is much stronger.
OSWorld-Verified tests how well the AI can use a computer—like clicking buttons, opening apps, and finishing tasks step by step. Both models scored almost the same (72.5% vs 72.7%). Since Sonnet costs much less (about 5 times cheaper), Sonnet is the better deal for computer-using tasks.
ARC-AGI-2 tests how well the AI can solve new kinds of puzzles it hasn’t seen before. Sonnet 4.6 got 60.4%, which is pretty good. But we can’t compare it directly to Opus 4.6 here, because Opus’s score wasn’t shared.
Pricing Breakdown —— Per-Token Costs
| Modèle | Entrée | Sortie | Effective Cost Multiplier |
| Sonnet 4.6 | $3 / 1M tokens | $15 / 1M tokens | 1x (baseline) |
| Opus 4.6 | $15 / 1M tokens | $75 / 1M tokens | 5x |
