Constructing your Generative AI apps with Meta’s Llama 2 and Databricks

In the present day, Meta launched their newest state-of-the-art giant language mannequin (LLM) Llama 2 to open supply for industrial use¹. It is a vital growth for open supply AI and it has been thrilling to be working with Meta as a launch accomplice. We had been capable of attempt Llama 2 fashions upfront and have been impressed with it’s capabilities and all of the potential purposes.

Earlier this yr, Meta launched LLaMA, which considerably superior the frontier of Open Supply (OSS) LLMs. Though the v1 fashions will not be for industrial use, they drastically accelerated generative AI and LLM analysis. Alpaca and Vicuna demonstrated that with high-quality instruction-following and chat information, LLaMA may be nice tuned to behave like ChatGPT. Based mostly on this analysis discovering, Databricks created and launched the databricks-dolly-15k instruction-following dataset for industrial use. LLaMA-Adapter and QLoRA launched parameter-efficient fine-tuning strategies that may nice tune LLaMA fashions at low value on client GPUs. Llama.cpp ported LLaMA fashions to run effectively on a MacBook with 4-bit integer quantization.

In parallel, there have been a number of open supply efforts to provide related or greater high quality fashions than LLaMA for industrial use to allow enterprises to leverage LLMs. MPT-7B launched by MosaicML turned the primary OSS LLM for industrial use that’s similar to LLaMA-7B, with extra options, such asALiBi for longer context lengths. Since then, now we have seen a rising variety of OSS fashions launched with permissive licenses like Falcon-7B and 40B, OpenLLaMA-3B, 7B, and 13B, and MPT-30B.

Newly launched Llama 2 fashions is not going to solely additional speed up the LLM analysis work but additionally allow enterprises to construct their very own generative AI purposes. Llama 2 contains 7B, 13B and 70B fashions, educated on extra tokens than LLaMA, in addition to the fine-tuned variants for instruction-following and chat. 

Full possession of your generative AI purposes

Llama 2 and different state-of-the-art commercial-use OSS fashions like MPT provide a key alternative for enterprises to personal their fashions and therefore totally personal their generative AI purposes. When used appropriately, use of OSS fashions can present a number of advantages in contrast with proprietary SaaS fashions:

• No vendor lock-in or pressured deprecation schedule
• Potential to  fine-tune with enterprise information, whereas retaining full entry to the educated mannequin
• Mannequin habits doesn’t change over time
• Potential to serve a personal mannequin occasion inside trusted infrastructure
• Tight management over correctness, bias, and efficiency of generative AI purposes

At Databricks, we see many purchasers embracing open supply LLMs for numerous Generative AI use instances. As the standard of OSS fashions proceed to enhance quickly, we more and more see clients experimenting with these fashions to match high quality, value, reliability, and safety with API-based fashions.

Growing with Llama 2 on Databricks

Llama 2 fashions can be found now and you may attempt them on Databricks simply. We offer instance notebooks to indicate how one can use Llama 2 for inference, wrap it with a Gradio app, effectively nice tune it together with your information, and log fashions into MLflow.
