CodeAF is an open-source Go coding harness built for open models like DeepSeek, Qwen, and GLM

AgentField's Apache-2.0 CodeAF ships as one 53 MB binary (curl -fsSL https://agentfield.ai/get/codeaf | bash) that turns each request into its own task on its own branch, runs it on a per-task crew of open models via OpenRouter, provider keys, or local Ollama, and claims first place among ten harnesses on DeepSWE with DeepSeek V4 Flash. It's an early preview with anonymous telemetry on by default, which CODEAF_TELEMETRY=off or DO_NOT_TRACK=1 turns off.
