# Qwen2.5-397B
> **⚠️ Misnamed page / alias.** Re-reading the source screenshot confirms the model is actually **Qwen3.5-397B-A17B**, not Qwen2.5. The "Qwen2.5" label (including the variant **Qwen2.5-397B-A17B**) is incorrect and is retained only as an alias to avoid breaking inbound links. This page should be merged into [qwen3.5-397b](/concepts/qwen3-5-397b).
See [qwen3.5-397b](/concepts/qwen3-5-397b) for the canonical, source-accurate content.
