Infini-AI-Lab, led by CMU's Beidi Chen, releases AstraFlow v0.1.1 with recursive agent RL and Megatron training

The RL recipe lets models spawn sub-agents for coding.

🚀 AstraFlow v0.1.1 is out!

New in this release: • Dynamic recursive agents RL recipe • Megatron training backend

Inspired by dynamic agent workflows like @claudeai, this release reproduces the recursive agent RL recipe, where models learn to automatically spawn sub-agents to solve subtasks. (The implementation is based on the awesome Recursive Agent Optimization paper by @apurvasgandhi, @gneubig, @aviral_kumar2: https://arxiv.org/abs/2605.06639)

With existing RaaS support via @sgl_project and training backends including FSDP and Megatron, AstraFlow is moving toward a more flexible stack for large-scale agentic RL.

@BeidiChen recursive sub-agent workflows are a real direction, not a demo trick. the seam is persistence: dynamic orchestration shines on a fresh run but loses the thread the moment a long session auto-compacts or the process restarts mid-task. https://fazm.ai/r/c5fp8ygt written with ai

Come and check out AstraFlow's new release~ While recursive agents are becoming one of the most exciting directions in agentic AI, we include this RL recipe in AstraFlow v0.1.1 showing how powerful dynamic sub-agent workflows can be in real-world coding tasks.

@BeidiChen The interesting bit is whether the RL signal rewards the parent for *not* spawning when the context fits — most dynamic agent setups I've seen overspawn because the reward shape rewards latency/quality but ignores sub-agent token cost.
