Overview

Anthropic: Claude Sonnet 5 is a large language model API from Anthropic, part of its Claude Sonnet model family. Priced at $2.00 per million input tokens and $10.00 per million output tokens, it occupies the mid-range, balancing capability against running cost. Output tokens cost about 5× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. An exceptionally large 1M-token context window (≈1,500 pages of text) means entire repositories or document collections can be processed without chunking. Beyond plain text it also accepts Image, File input, so it can be applied to multimodal tasks rather than text alone. On Artificial Analysis's Intelligence Index it scores 53 (A grade), a useful proxy for its general reasoning strength relative to the other models tracked here. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
