Detecting end-of-parameter in constrained JSON decoding with Qwen3-0.6B
Al-Khobza · reddit · 2026-09-15
A developer building function-calling on Qwen3-0.6B with constrained decoding faces a tricky problem: knowing when the model has finished predicting a parameter name without over-generating tokens.
Tried so far:
- Forcing <|imend|> endings — didn't work;
- Cutting at commas or curly braces — breaks when parameter values contain those characters;
- Special tokens like <eos> seem ideal since they never appear in text.
They're asking how best to detect completion or force the model to emit an <eos> token reliably.
