Dolly-V2-7B: Open Instruction-Tuned Chat AI by Databricks

Dolly-V2-7B

Open Instruction-Tuned LLM for Business & Research

What is Dolly-V2-7B?

Dolly-V2-7B is an open-source, instruction-tuned large language model developed by Databricks, based on the EleutherAI Pythia-7B architecture. It was fine-tuned using a high-quality, human-generated dataset for instruction following, offering a transparent, modifiable alternative to closed models like GPT-3.5.

This model is designed for enterprise, research, and educational use, delivering good conversational and task-solving performance without the burden of restrictive licensing or cloud APIs.
