What the numbers mean

What this model is

BAPO 32B was published by Fudan University,Shanghai Qiji Zhifeng, in China, in October 2025. It comes out of academia,Industry.

It works in Language, and is recorded as doing language modeling/generation, Question answering.

Its starting point was Qwen2.5-32B — most models at this scale are adapted from an existing base rather than built from nothing.

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

Answers

BAPO 32B — common questions
