Anthropic has released Claude 3.7 Sonnet, its best large language model (LLM) for solving real-world coding problems, along with the first agentic coding tool.
The company calls Claude 3.7 Sonnet the first hybrid reasoning model on the market meaning that it can act both as an ordinary and a reasoning LLM.
In standard mode, the model represents an improvement on its previous model, Claude 3.5 Sonnet. In extended thinking mode, it self-reflects before answering, resulting in better performance on various tasks.
According to Anthropic, those who use Claude 3.7 Sonnet through the API can control the “budget” for thinking. For example, users can tell Claude to think for no more than N tokens, allowing one to trade off speed and cost for the quality of the answer.
Improved coding capabilities and a coding agent
The previous version of Anthropic’s LLM was appreciated for its capabilities in coding for its speed.
Claude 3.7 Sonnet further enhances coding performance, including front-end tasks. Anthropic says the new model is optimized for real-world tasks rather than solving math and computer science problems.
The Claude 3.7 Sonnet is available on all Claude plans including the free version, while the Extended thinking mode is included in all plans except the free tier.
Claude 3.7 Sonnet is a significant upgrade over its predecessor. Extended thinking mode gives the model an additional boost in math, physics, instruction-following, coding, and many other tasks.

The company has also released its first agentic coding tool, Claude Code, which, “can search and read code, edit files, write and run tests, commit and push code to GitHub, and use command line tools.”
In early testing, Claude Code completed tasks in a single pass that would normally take 45+ minutes of manual work, Anthropic says in its blog post.
Anthropic is seeking funding
Anthropic is currently seeking $3.5 billion in funding. This would value the company at $61.5 billion, the Wall Street Journal and Reuters reported citing sources familiar with the matter.
The company is seeking funding from Ventur Ferns Lightspeed Venture Partners, General Catalyst, and Bessemer Venture Partners to advance development in the booming AI field.
OpenAI, the company behind ChatGPT, is also in talks for a mega funding round that could value it at up to $300 billion, according to Reuters.
