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. ## News - [2026/06] Deep dive into the design and optimization of TokenSpeed-Kernel.
