Anthropic releases Claude 3.5 Sonnet
Anthropic released Claude 3.5 Sonnet, with state-of-the-art results on coding, reasoning, and vision benchmarks at one-fifth the cost of Claude 3 Opus, plus a 200k context window and an upgraded Artifacts workspace.
Why it matters
Claude 3.5 Sonnet set a new cost-to-capability ratio for frontier models and became the default for many coding-agent products, so its release reshaped pricing across the API market.
