Maker	Anthropic^[1][2]
Thinking	Standard or extended thinking, same price
API price per 1M tokens	$3 input, $15 output (thinking tokens included)

Language model rubric2026 criteria

Estimate from the version's published specs, benchmarks and reviews, 0-5; scores are only comparable within one criteria year. Scored as launched (Claude 3.7 Sonnet, 24 Feb 2025): 200K-token context (OpenRouter model page, released 24 Feb 2025; Willison notes 64K output, 128K in beta); price $3 in / $15 out per 1M tokens including thinking tokens = $6 blended at 3:1 (Anthropic); text and image input. Reasoning null: no launch-version Artificial Analysis Intelligence Index entry was opened (AA now re-scores on v4.1); Anthropic's headline results (SWE-bench Verified 63.7%, 70.3% with its scaffold) have no anchor. Coding null (no Terminal-Bench 4.0). Speed null (no tokens/s). Reviews: Zvi, Tom's Guide (7-prompt face-off vs GPT-4o, page last updated 2 May 2025, original date not shown), Willison, The Decoder.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.

Anthropic called Claude 3.7 Sonnet "our most intelligent model to date and the first hybrid reasoning model on the market": one model that gives near-instant answers or "extended, step-by-step thinking that is made visible to the user"^[1][4]
It went out to every Claude plan - Free, Pro, Team and Enterprise - and to the Claude Developer Platform, Amazon Bedrock and Google Cloud's Vertex AI; extended thinking is on every surface except the free tier^[1][4]
Claude Code, Anthropic's first agentic coding tool, launched with it as a limited research preview that works from the terminal, and the GitHub integration came to every Claude plan^[1]
It cuts unnecessary refusals by 45% against its predecessor and was released under the ASL-2 standard^[1][2]
The version jumped from 3.5 to 3.7, and in February 2025 Claude 3.7 Sonnet began playing Pokémon Red live on Twitch^[3][4]

Notable features

$3 per million input tokens and $15 per million output tokens in both modes, thinking tokens included^[1][4]
API users set a thinking budget of any size up to the 128K-token output limit, trading speed and cost for quality^[1]
Anthropic's charts give 62.3% on SWE-bench Verified (70.3% with a custom scaffold) against 49.0% for the upgraded 3.5 Sonnet, and 81.2% (retail) and 58.4% (airline) on TAU-bench^[1]
Anthropic says it optimized less for maths and coding competitions and more for real-world business tasks^[1]
In standard mode it is an upgraded Claude 3.5 Sonnet; in extended thinking mode it reflects before answering, which helps maths, physics, instruction following and coding^[1]

Pass@1 averaged over several trials (up to 16 for AIME and SWE-bench Verified); a second figure benefits from parallel test-time compute. ¹ o1 TAU-bench results were reported by OpenAI and later deleted; TAU-bench results may not be comparable. ² 62.3% is pass@1 on 500 problems with bash/editor tools plus a "thinking tool"; 70.3% uses internal scoring and a custom scaffold on a reduced subset; DeepSeek R1 uses the Agentless framework. ³ Claude 3.7 Sonnet's high GPQA and AIME 2024 scores use internal scoring with parallel test-time compute; o1's and Grok 3's use majority voting with 64 samples.
