In this video, I'll be telling you about Anthropic's new Programmatic Tool Calling capability, or PTC, and how it's changing the way agents handle multi-step tasks while using fewer tokens and delivering better results. -- Key Takeaways: š§ Anthropic introduced Programmatic Tool Calling (PTC), a new capability available in Claude Opus and Sonnet 4.6. ā” PTC lets Claude write code that orchestrates multiple tool calls inside a container, reducing round-trip overhead. š PTC improved accuracy by 11% on average while using 24% fewer input tokens across benchmarks. š Opus 4.6 with PTC is currently ranked number one on LMArena's Search Arena benchmark. š§ PTC is now built into the web search tool on the API by default, so you get the benefits automatically. š You still keep full control through tool handlers for logging, inspection, and human approval. š Overall, PTC gives you the best of both worlds: the composability of code and the control surface of tools.
