BFCL v4 results show PTC matching or beating JSON tool calling on 11 of 14 models, with the GPT-5.6 family up 10.6% and better stability under context degradation and parallel execution. Most agent frameworks hard-code structured output as the default. On current models that default costs you accuracy.
