When this model is cost-effective
Claude Sonnet 5 ranks 2 of 11 Anthropic records by combined list price ($12.00 for 1M input plus 1M output tokens). That puts it in the lower-priced third of this provider's committed records.
Cached input reads are listed at $0.200 per 1M tokens, 10% of the fresh input rate, so repeated cached prompts have a lower committed input-token cost than fresh prompts.
The committed context window is 1M; use that as the only long-context signal on this page, not as a quality or latency claim.
