SAN FRANCISCO--(BUSINESS WIRE)--Predibase, the developer platform for fine-tuning and serving LLMs, today launched the Fine-Tuning Index to showcase how fine-tuning open source LLMs dramatically improves their performance for production applications, ranking the top LLMs by performance for various tasks. Drawing from over 700 fine-tuning experiments, this comprehensive resource is designed to aid enterprise AI teams in selecting the optimal open-source model for their specific applications and reports the performance of 13 of the most popular open-source LLMs across 31 distinct tasks compared to leading commercial LLMs. View the index here.
“Most organizations recognize that open-source LLMs are closing the performance gap between commercial models like GPT-4, but many are surprised when they learn that open-source LLMs already significantly outperform GPT-4 when fine-tuned for specific applications,” said Dev Rishi, co-founder and CEO of Predibase.
Furthermore, teams often don’t know which open-source LLM will perform best for their set of tasks. While there may be a general feeling that certain LLMs may be more performant out of the box, the nuances in performance between base models and fine-tuned LLMs across different task types has never been studied and reported on in aggregate. The Fine-Tuning Index helps teams more confidently select the most appropriate open-source LLM for a given application so they can spend less time in trial and error comparing model results and get to production faster with the right fine-tuned LLM.
Key findings from the research powering the Fine-Tuning Index include:
- Outperformance of GPT-4: The majority of fine-tuned open-source models exhibited superior performance compared to GPT-4 and GPT-4o, with Llama 3, Phi-3, and Zephyr leading the pack.
- Cost-Effectiveness: Fine-tuned models proved to be not only more cost-effective but also faster to train and serve, with GPT-4 costing orders of magnitude more per month for a given enterprise use case. Plus, fine-tuning each LLM for a typical task only cost about $8 in terms of compute.
- Specialized Task Superiority: Fine-tuned LLMs excel in specialized tasks, such as legal contract review and medical classification, surpassing the performance of GPT-4 on 85% of tested tasks.
- Optimal Base Models: Llama 3, Phi-3, and Zephyr architectures emerged as the top choices for fine-tuning, offering superior performance across various tasks.
These findings are discussed in greater detail in a report recently published by the Predibase research team titled “LoRA Land: 310 Fine-tuned LLMs that Rival GPT-4, A Technical Report.” Predibase's research not only showcases the capabilities of open-source LLMs but also provides valuable insights and tools for organizations looking to leverage these models effectively. By democratizing access to advanced language models and empowering developers with cost-effective solutions, Predibase is paving the way for teams bringing AI products to market.
