Fixing Tool-Call Accuracy in vLLM
Summary
Ubicloud's blog post examines tool-call accuracy in vLLM for open-weight models, introduces constrained decoding to guarantee schema-adherence, and shares benchmarks (K2VV) and Ubicloud's practical implementation achieving 100% tool-call schema accuracy. It explains tool-call schemas, constrained decoding, and the impact of inference engines on model output quality.
