Install with npm install g @garuda agent/garuda ; it works with Claude, OpenRouter, and local OpenAI compatible models…
Xiamen University et al. open ProgramGym: 1,648 verifiable C/C++/Go/Rust environments built from GitHub repos for agents that rebuild programs from black box behavior, plus a role isolated Program Agent harness. Fine tuning Qwen3.8 27B on its trajectories raised ProgramBench from 34.87% to 42.84%; with Program Agent the SFT model hit 56.25%…
