Everyday Claude agent model for coding, planning, browsing, and general work
Claude Sonnet 5 by anthropic is offered by 40 providers on this page. Public prices are shown for 37 of them. Its official list price is $2.00 per 1M input tokens and $10.00 per 1M output tokens. The lowest paid channel is UnoRouter at $1.44 / $7.20 per 1M, about 2.1× below the list price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it. It also has 1 free ($0) channel; free tiers usually carry rate limits, and subscription-covered access bills $0 per token only after the subscription fee.
Artificial Analysis rates it 38.2 on the Intelligence Index, with 71.5 for coding and 43.6 for agentic tasks. Against its lowest blended price of $2.88 per 1M, that is roughly 13 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 86 tokens per second, with 205.17s to the first token. Running one task of the Artificial Analysis suite costs about $5.0912, which reflects how many tokens its reasoning consumes rather than the unit price alone.
The context window is 1,000,000 tokens, with an output limit of 128,000 tokens. It supports reasoning, tool use, and structured output. Accepted input modalities are Text, Image, and PDF. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2026-01-31.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

Sorted by blended price (input×0.75 + output×0.25) asc. The official channel always shows regardless of rank. Whether a gateway's low price is actually usable can't be verified.
Interleaved thinking (reasoning between tool calls) is declared by 3 of 40 providers.
4 / 40 providers expose no reasoning control (reasoning_options: []).
1 more channels offer $0 (Kenari); free tiers usually have rate limits and no SLA, excluded from ranking.

The same benchmark scores very differently across harness / dataset, so the qualifying conditions must be shown together.
Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
