Anthropic's Claude Sonnet 4 Now Supports 1M Tokens
Anthropic Breaks New Ground with 1M Token Support for Claude Sonnet 4
Artificial intelligence company Anthropic has made a significant leap forward by announcing 1 million token context support for its Claude Sonnet 4 language model. This development positions Anthropic as only the second major AI provider after Google Gemini to offer such extensive context capabilities.
Expanded Capabilities for Developers
The previous 200,000 token limit has been increased fivefold, allowing developers to submit:
- Entire codebases (75,000+ lines)
- Large research documents
- Complex datasets
Availability and Pricing Structure
The long-context feature is currently in public testing through:
- Anthropic's API
- Amazon Bedrock
- Coming soon to Google Cloud Vertex AI
Pricing tiers have been introduced:
- Under 200K tokens: $3/M input, $15/M output tokens
- Over 200K tokens: $6/M input, $22.5/M output tokens Developers can reduce costs through batch processing (50% discount available).
Competitive Landscape Shifts
The move creates pressure on OpenAI, whose executives recently stated during a Reddit AMA that they're monitoring demand for long-context features. OpenAI's Michelle Pokrass revealed that GPU limitations prevented implementing similar capabilities in GPT-5.
Key Points:
- Industry-first: Second provider after Google to reach 1M token support
- Developer impact: Enables processing of entire code repositories at once
- Cost considerations: Tiered pricing reflects increased computational demands
- Market dynamics: Forces competitors to reevaluate product roadmaps
