NVIDIA's Polar Enables Agentic RL on Any Harness at Scale
SergioPaniego · x · 2026-08-20
The post discusses a new work, "Polar: Agentic RL on Any Harness at Scale," which turns existing agent harnesses (like Codex, Claude Code, Qwen Code) into RL training environments without modifying their internals. This approach is credited for the high performance of frontier agents. The post also links to related blog posts and a full worked example using GRPO.
