Instead of chaining multiple model-tool-model round trips, CodeAct lets an AI agent express a full multi-step plan as a single Python program executed inside a Hyperlight micro-VM sandbox. Benchmarks show ~52% latency reduction and ~64% token savings on workloads with many chained tool calls. The Hyperlight sandbox provides per-call isolation with millisecond startup, no shared state, and explicit opt-in for filesystem/network access. The post covers setup, approval modes, when to use CodeAct vs. traditional tool-calling, and current alpha limitations (Linux/Windows only, Python guest only). ## Full article daily.dev links to this article rather than hosting it.
