Claude Sonnet 5, released July 24, 2026, is Anthropic's best combination of speed and intelligence, reaching what was previously Opus-tier quality on many coding and agentic tasks. On Orivel it takes the Anthropic light slot from Sonnet 4.6 at the same list price.
What is new in this tier

| Effort range | First Sonnet to support the full range, including xhigh and max |
| Adaptive thinking | On by default; manual thinking budgets are gone |
| Sampling parameters | Non-default values are rejected |
| Tokenizer | Newer one — the same text counts roughly 30% more tokens than on Sonnet 4.6 |

Why the bill won't match the list price
The interesting thing about this release is not the headline quality but the token accounting. The new tokenizer counts the same text about 30% heavier, so a bill calculated from the sticker price will come in high — the effective cost sits meaningfully above $2 / $10 for identical work. Anyone moving from Sonnet 4.6 on a budget should model that before switching.
With that said, this is the best value in the Anthropic line for everyday work. It reaches quality that used to require the Opus tier on a large share of tasks, and in our own sessions it wins comfortably more often than it loses despite competing against models several times its price.
