Introducing Databricks Llama 2 70B Chat: A Cutting-Edge Language Model for Interactive Applications
Databricks is excited to introduce the Llama 2 70B Chat, a state-of-the-art 70 billion parameter language model developed by Meta AI. Optimized for chat and interactive applications, this model excels in tasks such as summarization, question-answering, and dialogue.
Availability and Support
The Llama 2 70B Chat model is currently available on the Databricks Marketplace and can be easily deployed using the Databricks Lakehouse AI platform. However, please note that this model is planned for retirement and will no longer be supported after October 30, 2024. Users are encouraged to plan accordingly and consider transitioning to newer models such as Meta Llama 3.1.
Capabilities and Performance
With a context length of 4,096 tokens, Llama 2 70B Chat delivers high-quality performance comparable to leading models like OpenAI's ChatGPT. It is particularly strong in tasks requiring robust reasoning capabilities and is optimized for dialogue use cases.
Deployment and Integration
The model can be fine-tuned and deployed on private model serving endpoints using Databricks Lakehouse AI, wrapped in MLflow for seamless deployment and evaluation. Additionally, it can be accessed via MosaicML Inference for enterprise-grade reliability, security, and performance.
Centralized Governance and Management
Databricks ensures centralized governance through Unity Catalog, providing auditing and lineage tracking. The MLflow AI Gateway supports centralized management of LLM credentials and deployments, offering standardized interfaces and cost management.
Limitations and Recommendations
Like other large language models, Llama 2 70B Chat may sometimes omit facts or produce false information. For scenarios requiring high accuracy, Databricks recommends using retrieval augmented generation (RAG).
With the upcoming retirement of the Llama 2 70B Chat model, now is the perfect time to explore newer alternatives like Meta Llama 3.1, ensuring continuous support and cutting-edge performance.
