Anthropic's Claude Sonnet 4 Gets 1M Token Boost
Anthropic has updated its Claude Sonnet 4 AI model.
This AI can now understand much longer prompts, like entire books or long coding projects.
This helps developers who want the AI to analyze large amounts of data or code.
While this is useful, it will cost more to use the AI.
Anthropic's Claude Sonnet 4 now features a 1 million token context window.
This expanded context allows for longer prompts, such as 75,000 lines of code.
The update aims to attract developer-focused businesses to the platform.
Claude can now handle complex tasks like large-scale code analysis and document synthesis.
Increased computing power will cause the cost of Claude Sonnet 4 API to increase for certain token ranges.
