New in Qwen 2.5 72B over Qwen2 is the combination of broader knowledge, stronger instruction following, longer text generation, and structured JSON output. The 72B variant remains a dense, text-only instruct model without a Mixture-of-Experts design.

The open repository handles up to 131,072 tokens and can generate up to 8,192 tokens. Qwen’s official Qwen2.5 announcement gives up to 18 trillion training tokens for the series, not as a separate figure for this checkpoint. Qwen 3 32B belongs to the later Qwen3 generation and has 32.8 billion parameters according to its model card.
