ByteDance Open-Sources deer-flow: Long-Horizon SuperAgent Harness for Sandboxed Research & Coding

ByteDance has open-sourced **deer-flow**, a SuperAgent orchestration runtime designed for tasks requiring hundreds of sequential tool calls in ephemeral environments.

Isolated Execution Sandboxes deer-flow automatically boots sandboxed Docker containers for each agent thread, isolating filesystem changes, shell processes, and network requests. Integrated with Qwen3.8 and DeepSeek-V4.1, deer-flow handles multi-day research workflows, scientific paper synthesis, and automated code review pipelines.
