Anthropic Unveils Claude 3.7 Sonnet AI Model

On Monday, Anthropic launched its latest artificial intelligence model, Claude 3.7 Sonnet, now available to all users of the Claude platform. This upgraded version is touted as the company’s most intelligent model yet, emphasizing advanced reasoning capabilities. A key feature of this release is Claude Code, Anthropic’s inaugural agentic coding tool designed to tackle a wide range of backend coding tasks.
Anthropic Releases New AI Model and Its First AI Agent
In an official announcement, Anthropic introduced the Claude 3.7 Sonnet model, marking its first hybrid AI model. This innovative design allows the model to function both as a standard language model and a reasoning model. Reasoning models enhance their output by utilizing test-time compute functions, which enable them to reassess responses, explore alternative solutions, and verify information before finalizing an answer.
With Claude 3.7 Sonnet, users can seamlessly switch between standard and reasoning functions within the same AI model. Anthropic explained their rationale for adopting a hybrid approach, stating, โWe believe reasoning should be an integrated capability of frontier models rather than a separate model entirely.โ Early access by Gadgets 360 staff revealed that the responses generated by this model are notably more sophisticated than those from the previous Sonnet version, although improvements remain incremental, as is common with iterative AI advancements.
Enhanced Features and User Experience
The Claude 3.7 Sonnet model introduces a new Thinking Mode feature, allowing users to choose between Normal and Extended modes. The Normal mode delivers near-instant responses, while the Extended mode focuses on reasoning-based outputs. Currently, the Extended mode is exclusive to Pro subscribers, providing them with deeper insights and more thoughtful responses.
Developers utilizing the model through the application programming interface (API) can now control the duration of the model’s reasoning process before it generates an output. This control is achieved by setting a specific token value, which can reach up to 128,000 tokens, the maximum limit for this model. Anthropic emphasized that this level of granularity will enable developers to create more targeted and effective products.
Performance Metrics and New Coding Tool
In terms of performance, Claude 3.7 Sonnet achieved a score of 62.3 percent in the SWE-bench verified benchmark, surpassing its predecessor, the 3.5 Sonnet, as well as OpenAI’s o1 model, according to Anthropic’s internal testing. Additionally, it outperformed o1 in the TAU-bench benchmark, which assesses agentic tool usage.
Alongside the new AI model, Anthropic also introduced Claude Code, its first agentic coding tool, currently available in a limited research preview. This tool is capable of executing a variety of coding tasks, including searching and reading code, editing files, writing and running tests, and managing code on GitHub. Internal testing revealed that Claude Code could complete complex tasks that typically require over 45 minutes of manual effort in a single attempt. Interested users can access the preview of this innovative tool through Anthropic’s platform.
