About

Claude Sonnet 5 is a large language model from Anthropic, listed here with its "Max" configuration (the highest reasoning-effort setting, as referred to by creators). It belongs to the Sonnet tier of the Claude family and is accessed through Anthropic's apps and API.

According to Anthropic's homepage, Claude Sonnet 5.5 is now a "clear upgrade over Claude Sonnet 5", running 30%+ faster and costing up to 30% less for most work. Sonnet 5 has therefore been superseded within the Sonnet line, and newer Opus 5.5, Fable 5.2 and Mythos 5.2 models are also listed.

In cost-per-task comparisons discussed by YouTube creator Matthew Berman, Sonnet 5 Max was described as having roughly the same intelligence as GPT-5.6 Luna max but at about $1.80 per task versus about 6 cents, making it notably more expensive on that chart. These figures come from a third-party commentary and are not official Anthropic benchmarks. Detailed specifications, context window and per-token prices were not available in the provided material.
