Claude 3.5 Sonnet

Claude 3.5 Sonnet is a large language model from Anthropic’s Claude family, introduced on 20 June 2024. At launch it outperformed the previous most capable model, Claude 3 Opus, across a wide range of evaluations, while operating about twice as fast and at a lower price.

The model is multimodal — it takes text and images (photos, charts, documents) and produces text responses. It supports a 200,000-token context window and was described as Anthropic’s strongest vision model at launch. It launched alongside the Artifacts feature in claude.ai (an interactive window for generated content).

On 22 October 2024 Anthropic released an upgraded Claude 3.5 Sonnet (claude-3-5-sonnet-20241022) with markedly better coding results (SWE-bench Verified 49.0%) and a new, experimental “computer use” capability in public beta — the model can operate a computer interface (view the screen, move the cursor, click, type).

API pricing was USD 3 per 1M input tokens and USD 15 per 1M output tokens. The model was available via the Claude API, claude.ai (and the iOS app), Amazon Bedrock and Google Vertex AI. Claude 3.5 Sonnet is now a previous-generation model, superseded by newer Claude models.
