Claude 3.7 Sonnet Gains Parallel Tool Calling and Improved Agent Reliability

Anthropic updated Claude 3.7 Sonnet to support parallel function calling, allowing agents to invoke multiple tools simultaneously rather than sequentially. Internal benchmarks show up to 60% reduction in round-trip latency for multi-step agentic workflows. The update is live across the Anthropic API and Amazon Bedrock with no pricing changes.
