What is Claude 3.7 Sonnet?

Claude 3.7 Sonnet model is a large language model developed by Anthropic and introduced as the first hybrid reasoning model in the market. Claude 3.7 Sonnet shows particularly strong improvements in coding and front-end web development. Claude 3.7 Sonnet model has two different generation modes. Claude 3.7 Sonnet model's normal generation mode is ideal for generating output quickly, while its extended mode shows the step-by-step generation process and is ideal for reasoning tasks.

Claude 3.7 Sonnet is a model that combines both ordinary LLM capabilities and reasoning models in a single AI tool. You can pick when you want the model to answer normally and when you want it to think longer before answering. The standard Claude 3.7 Sonnet model has higher performance than its predecessor Claude 3.5 Sonnet model.

How to Access Claude 3.7 Sonnet?

Claude 3.7 Sonnet is now available on all Claude plans including Free, Pro, Team, and Enterprise, as well as the Anthropic API, Amazon Bedrock, and Google Cloud’s Vertex AI. In other words, you can access Claude 3.7 Sonnet via Anthropic’s AI chatbot. However, the Claude Free plan only supports Claude 3.7 Sonnet normal mode, not Claude 3.7 Sonnet extended mode. Another way to access Claude 3.7 Sonnet is to add it as an API to your AI tool. You can also access Claude 3.7 Sonnet using Google Cloud’s Vertex and Amazon Bedrock tools.

Claude 3.7 Sonnet Pricing

To access the Claude 3.7 Sonnet model, you need to have one of the paid Claude plans. Pricing for the Claude plans includes:

• Claude Pro: $20 / Month (with an annual subscription of $18 / month)
• Claude Team: $30 / Month (with an annual subscription of $25 / month)
• Claude Enterprise: Custom Pricing

The Claude 3.7 Sonnet model has the same API pricing as its predecessor, the Claude 3.5 Sonnet model. API pricing of the Claude 3.7 Sonnet model is as follows;

• Input: $3 / million tokens
• Prompt caching write: $3.75 / million tokens
• Prompt caching read: $0.30 / million tokens
• Output: $15 / million tokens

Claude 3.7 Sonnet Features

Claude 3.7 Sonnet model is a hybrid LLM that offers users advanced performance and new features. With the Claude 3.7 Sonnet model, you can both complete reasoning tasks and use it like conventional LLMs. Let’s discover advanced and new features of Claude 3.7 Sonnet together!

Claude 3.7 Sonnet Extended Thinking

Claude 3.7 Sonnet model's extended generation mode generates thinking content blocks that explain the parameters running in the background for users. Claude 3.7 Sonnet extended thinking mode provides high performance for reasoning, math, and coding tasks. When you activate this mode, you get more accurate outputs, although your response time will be longer.

You can set Claude 3.7 Sonnet extended mode from AI chatbot settings. Also, to use it as an API, you just need to enter the thinking parameter. Also, your “budget_tokens” parameter must always be higher than your “max_tokens” parameter. Otherwise, the model will not work with extended mode, and you will not be able to get output.

Claude 3.7 Sonnet Performance & Benchmarks

The Claude 3.7 Sonnet model offers more advanced coding and reasoning skills than its predecessor. Anthropic developed the Claude 3.7 Sonnet model by training it with less for math and computer science competition problems, and more real-world tasks, and based it on how businesses use LLMs. The Claude 3.7 Sonnet model can produce production-ready code with superior design taste and minimal error output.

Claude 3.7 Sonnet model has scores competitive with OpenAI o1, o3-mini, DeepSeek R1 and Grok 3 Beta in 64K extended thinking mode. The Claude 3.7 Sonnet model has scores of 78.2% and 84.8% in the Graduate-level reasoning (GPQA Diamond) test in 64K extended mode, 86.1% in the MMLU benchmark, 86.1% in the MMMU benchmark and 96.2% in MATH 500 benchmark.

Claude Code

Developed by Anthropic and powered by Claude 3.7 Sonnet, the Claude Code feature works as an AI coding assistant that you can directly integrate into your terminal or codebase. It can understand your codebase and helps you generate code, debugging through natural language commands. By integrating directly with your developer environment, Claude Code streamlines your coding workflow without requiring additional setups or programs.
