HybridAgent reasons in latent space, acts via text — 2x faster, 3x cheaper, open-sourced
zainhas · x · 2026-10-15
James Zou's team (with Together AI and UIUC) introduces HybridAgent, a new agent architecture where the LLM thinks in latent space and only emits text when acting.
Key points:
- Smarter than standard LLM agents, 2x faster and 3x cheaper
- Latent thoughts are fully readable, not a black box
- One unified multi-turn flow with two modes; any LLM can become a HybridAgent
- RL and SFT training pipelines are open-sourced
