About Dolphin 2.9.2 Qwen2-72B
Dolphin 2.9.2 Qwen2-72B is Cognitive Computations' uncensored full-weight fine-tune of Qwen2-72B. The model card documents ChatML formatting, initial agentic abilities, and function calling support; it also notes the Qwen2 base has a 128K context window while the fine-tune used 8K training sequences. Because Dolphin removes much of the usual alignment filtering, deployments should add their own moderation and policy layer before exposing it as a public service.
