No The core contribution is a novel inference method that needs token-level control of a strong model's prefill and KV-cache behavior, plus research-grade evaluation on benchmarks like τ²-Bench. Calling hosted APIs can approximate the idea but not reproduce the speedup.
What it would actually take: A faithful build needs a local inference stack (e.g., vLLM or SGLang with prefill-only verification and cache reuse) running a small draft model and a large verifier model, plus a tool-execution sandbox that separates read-only calls from state-changing ones. The hard parts are the verification prompt and decision logic that reliably accept or reject drafted trajectories, and the systems work to make single-pass review cheap. This takes ML systems and LLM research expertise and multi-GPU hardware.
