README.md

TokenSpeed is a speed-of-light LLM inference engine designed for agentic workloads, with TensorRT-LLM-level performance and vLLM-level usability. Our goal is to be the most performant inference engine for production agentic workloads.

Core components:

• Modeling layer: local-SPMD design with a static compiler that generates collective communication from module-boundary placement annotations, so users do not hand-write parallelism logic.
• Scheduler: C++ control plane and Python execution plane. Request lifecycle, KV cache ownership, and overlap timing are encoded as a finite-state machine, with safe KV resource reuse enforced by the type system at compile time.
• Kernels: pluggable, layered kernel system with a portable public API and a centralized registry including one of the fastest MLA (Multi-head Latent Attention) implementations on Blackwell for agentic workload.
• Entrypoint: SMG-integrated AsyncLLM for low-overhead CPU-side request handling.
