Description

Hello,

Several people have reported having this issue for the v1.1 model, which wasn't a bug for the v1.0 one. Do you plan on fixing that in the future?

Research direction

The issue names only the v1.1 and v1.0 models and does not identify a file, entry point, or test. Start by locating the inference and stopping-token handling for both model versions, then reproduce the premature termination and add a regression test showing that normal generation does not stop early.
