About
Dolphin is Cognitive Computations' lineage of uncensored instruction-tuned LLMs led by Eric Hartford. The family started with Llama and Mistral bases, expanded through Mixtral, Yi, Phi, and Qwen releases, and combines open instruction data for chat, coding, math, function-calling, and agent workflows. Dolphin models are optimized for user steerability and broad task compliance while intentionally leaving alignment and policy filtering to the deployer, so production use should add external safeguards.
