Session brief
Building State of the Art Open Weights Tool Use: The Command R Family: Sandra Kublik
Overview
This talk introduces the Command R family of open-weight models, highlighting their capabilities in retrieval augmented generation (RAG), tool use, and sequential reasoning. The models are designed to be competitive with leading proprietary models like GPT-4 Turbo and Claude Opus, while being significantly smaller and more cost-effective. The presentation emphasizes the engineering decisions behind these models, focusing on addressing challenges in prompt sensitivity, model bias, and steering knowledge to improve performance in RAG and tool-use scenarios.
Who should watch
- AI Engineers
- Product Managers
- Developers building AI applications
- Those interested in open-source LLMs
- Builders working with RAG and tool-use functionalities
- Individuals seeking cost-effective, high-performance LLMs
Key takeaways
- The Command R and Command R+ models offer state-of-the-art performance in RAG and tool use, competitive with models like GPT-4 Turbo but at a fraction of the cost.
- Command R is optimized for RAG and scalability, while Command R+ excels in tool use and advanced RAG, gaining significant traction in the open-source community.
- Key engineering challenges addressed include prompt sensitivity, overcoming model bias towards the beginning of documents, and balancing pre-trained knowledge with external information for RAG.
- A major focus has been on fine-grained citations to enhance transparency and reduce hallucinations, allowing users to verify information sources.
- The open-source UI toolkit, built with Next.js, provides plug-and-play components for building chat interfaces with RAG and tool-use capabilities, supporting various model access methods.
- The Command R family supports both single-step and multi-step tool use, with the multi-step API enabling complex, sequential actions and self-correction.
- *The models are designed to be affordable but powerful enough to cover many use cases.*
- *Command R+ offers competitive performance to GPT-4 Turbo but is three to five times cheaper.*
