Claude Sonnet 4.6 vs Claude Sonnet 5
Published LiveBench scores across all seven categories, live list pricing, context windows, and the measured cost of a point of capability — for both models, side by side.
Claude Sonnet 5 wins outright — it scores higher and costs less.
Claude Sonnet 5 leads by 3.0 points overall while listing 1.5× cheaper per blended million tokens. There is no trade-off to reason about here; the only reason to pick the other is a constraint this table does not show, like an existing contract, a region, or a provider you are already on. The two cost measures disagree here, which is worth knowing: Claude Sonnet 5 has the lower sticker price, but Claude Sonnet 4.6 earns each point of capability for less — $0.1561 against $0.2691 — because per-token rates do not predict how many tokens a model actually spends on a task.

Which gives better value for money, Claude Sonnet 4.6 or Claude Sonnet 5?
Claude Sonnet 4.6. Cost per point divides the measured dollars LiveBench spent running the benchmark by the score it earned, so it captures something token pricing misses: a reasoning model can emit many times more tokens than its per-token rate suggests. Claude Sonnet 4.6 works out at $0.1561 per point and Claude Sonnet 5 at $0.2691.
Does Claude Sonnet 4.6 or Claude Sonnet 5 have a bigger context window?
They are effectively the same — 1M for Claude Sonnet 4.6 and 1M for Claude Sonnet 5.
Do Claude Sonnet 4.6 and Claude Sonnet 5 support prompt caching?
Both publish a cached-input rate: $0.300 per million for Claude Sonnet 4.6 and $0.200 for Claude Sonnet 5, against full input rates of $3.00 and $2.00. On a workload with a long stable prefix — a system prompt, a tool schema, a retrieved corpus — that changes the economics more than the headline price does.

How these numbers are produced
- Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
- Scores — LiveBench release 2026-06-25, using their own category map. Each model shows its strongest published run. A blank means “not evaluated”, never “bad”.
- Cost per point — the measured dollars LiveBench spent on the run, divided by the score it earned.
- “Win” — awarded only past a threshold: one full point on a benchmark score, 10% on a price, 25% on a context window. Anything tighter reports as a tie, because effort settings alone move a LiveBench score by more than that.
