Hello,
Today, we’re launching Claude 3.5 Sonnet—the first release in our Claude 3.5 model family. Claude 3.5 Sonnet raises the industry bar for intelligence, outperforming competitor models and Claude 3 Opus on a wide range of evaluations.
The model is now available for free on claude.ai and on the Claude iOS app. Claude Pro and Team plan subscribers benefit from significantly higher rate limits than the free plan and gain priority access during high-traffic periods.
What’s new? 
Frontier intelligence
Claude 3.5 Sonnet sets new industry benchmarks for graduate-level reasoning (GPQA), undergraduate-level knowledge (MMLU), and coding proficiency (HumanEval). It shows marked improvement in grasping nuance, humor, and complex instructions and is exceptional at writing high-quality content with a natural, relatable tone.
2x speed
Operating at twice the speed of Claude 3 Opus, Claude 3.5 Sonnet is ideal for complex tasks like code generation, writing high-quality content, summarizing lengthy documents with improved accuracy, creating insights and visualizations from unstructured data, and more. 
State-of-the-art vision
Claude 3.5 Sonnet is our strongest vision model, performing an average of ~10% better than Claude 3 Opus on all vision benchmarks. These step-change improvements are most noticeable for tasks that require visual reasoning, like interpreting charts and graphs. Claude 3.5 Sonnet can also accurately transcribe text from imperfect images.
Introducing Artifacts—a new way to use Claude
We’re also introducing Artifacts on claude.ai, a new feature that expands how you can interact with Claude. When you ask Claude to generate content like code snippets, text documents, or website designs, these Artifacts appear in a dedicated window alongside your conversation. This creates a dynamic workspace where you can see, edit, and build upon Claude’s creations in real-time, seamlessly integrating AI-generated content into your projects and workflows.
Get started
You can start using Claude 3.5 Sonnet for free today at claude.ai and on the Claude iOS app. For inspiration, visit our YouTube channel to watch demo videos and see our new Artifacts feature in action.
If you’re interested in building applications with Claude 3.5 Sonnet, you can also access it through our API.
As always, we look forward to seeing what you create and discover with Claude.
