Definition
A-Evolve is an open-source infrastructure from a-evo-lab (Amazon) for evolving AI agents across any domain using evolution algorithms with zero human intervention. PyPI package a-evolve v0.1.0.
A-Evolve-Training Milestone (June 2026)
First publicly documented autonomous post-training at 30B scale:
- Model: 30B NVIDIA Nemotron base
- Rounds: 4 self-directed rounds, weeks-long, no human intervention
- Result: 0.86 on Nemotron-Reasoning Challenge (8th of ~4,000; top human: 0.87)
- Self-correction: detected specification-gaming in internal metric, revised search policy autonomously
- Scale validation: same loop closed at 120B and 550B (infrastructure validation; no human baseline)
Architecture
- Immutable substrate
- Memory-free homogeneous workers (N=8 per round)
- Round-level policy updates by meta-agent
