Good news for @AnthropicAI devs:
We shipped a more token-efficient tool use implementation for 3.7 Sonnet that uses on average 14% less tokens under-the-hood and shows marked improvement in tool use performance.
Use this beta header: "token-efficient-tools-2025-02-19"
Today, we introduced Claude 3.7 Sonnet and Claude Code! Claude 3.7 Sonnet is our smartest model yet and the first hybrid reasoning model on the market. Claude Code is a command line tool for agentic coding, so developers can hand off complex engineering jobs to Claude.
Can't wait for folks to try them out, let me know what you think!
Within Anthropic, Claude Code is quickly becoming another tool we can't do without. Engineers and researchers across the company use it for everything from major code refactors, to squashing commits, to generally handling the "toil" of coding.
After installing Claude Code, simply run the "claude" command from any directory to get started.
Ask questions about your codebase, let Claude edit files and fix errors, or even have it run bash commands and create git commits.
Watch Claude Code in action:
Introducing Claude 3.7 Sonnet: our most intelligent model to date. It's a hybrid reasoning model, producing near-instant responses or extended, step-by-step thinking.
One model, two ways to think.
We’re also releasing an agentic coding tool: Claude Code.
Introducing the Model Context Protocol (MCP)
An open standard we've been working on at Anthropic that solves a core challenge with LLM apps - connecting them to your data.
No more building custom integrations for every data source. MCP provides one protocol to connect them all:
Claude can now view images within a PDF, in addition to text.
This helps Claude 3.5 Sonnet more accurately understand complex documents, such as those laden with charts or graphics.

Beyond inspiring to see the different Anthropic teams come together for this launch — our upgraded Sonnet is even better at coding and other tasks, and we have a beta computer API for you to try as well.
i have never once heard this song and i am so unbelievably chronically online and tapped into pop culture, stop giving this woman awards she doesn’t deserve
