How Claude 3.5 Sonnet Tokenization Works
Frontier Intelligence at Twice the Speed
Claude 3.5 Sonnet raises the industry bar, outperforming competitor models and even Claude 3 Opus on a wide range of evaluations. It operates at twice the speed of Opus, making it ideal for complex tasks that demand both intelligence and velocity.
Agentic Coding Pro
In internal tests, Sonnet 3.5 solved 64% of coding problems, outperforming Opus. It can independently write, edit, and execute code, making it perfect for updating legacy apps.
State-of-the-Art Vision
Sonnet 3.5 is Anthropic's strongest vision model, excelling at interpreting charts, graphs, and transcribing text from imperfect images.
Introducing Artifacts: A New Way to Work
Claude 3.5 Sonnet introduces Artifacts, a new feature on Claude.ai that creates a dynamic workspace. When you ask Claude to generate code, documents, or designs, they appear in a dedicated window where you can see, edit, and build upon them in real-time.
Cost-Effective Pricing for Next-Gen Performance
Despite its groundbreaking performance, Claude 3.5 Sonnet is available at the same cost-effective price as its predecessor, making next-generation intelligence highly accessible.
