Anthropic launches Claude Sonnet 5 with 1M-token context window
Anthropic has launched Claude Sonnet 5 as its new mid-size frontier model with 1 million tokens context window and improved agentic capabilities for planning, browser, and terminal tools. The model is available across all Claude platforms with introductory pricing at $2 per million input-tokens and $10 per million output-tokens through early September. The launch also includes Claude Desktop for Linux in beta and upgrades to Managed Agents with improved observability.
WHY IT MATTERS
Sonnet 5 represents a significant upgrade to Anthropic's mid-tier offering with agentic abilities that previously required larger models, and aggressive pricing signals intensifying competition in the frontier model market.
