Lean Verified Tokenizers Lean Verified Agent Tokenizers Lean Verified Tokenizers 🔗 Agent harnesses play a major role in the AI stack, allowing models that generate tokens to control complex real-world systems. This control is mediated through messages: structured commands parsed from those tokens that coordinate tool calls. The prominence of harnesses has brought renewed attention to tokenization in LLMs. The quirks of tokenization interact with harnesses in surprising ways, leading to a new class of nasty training bugs. In this blog, we build a formally verified tokenization pipeline with the goal of mitigating harness bugs. The blog is…
What people said about Lean Verified Tokenizers on X
Love seeing ideas from Miles' Token-In-Token-Out work inspire new research! Instead of just testing that training sees the exact tokens the model generated, Sasha takes it a step further, formally verifying key properties of a Rust tokenizer in Lean. That's the kind of rigor agentic RL needs. Fascinating work,…
