Leaderboards to Compare LLMs: Navigating the Ever-Evolving Landscape

LLMs are always changing, as new models keep appearing. While having lots of options is exciting, it can also be a bit overwhelming for developers, researchers, and tech enthusiasts. To help with this changing landscape, LLM leaderboards give us a clear picture of how different language models perform.

Let's take a look at some of them.

Open LLM Leaderboard

The HuggingFace Open LLM Leaderboard is a platform designed to track, rank and assess LLMs and chatbots as they gain popularity. It is unique because it is open to the community, allowing anyone to submit their model for automatic evaluation on the HuggingFace GPU cluster. The only requirement is that the model is a HuggingFace Transformers model with weights available on the Hub. They also allow for model evaluations with delta-weights for non-commercial licensed models, like the original LLaMa release. Users can easily filter models based on their type, whether pre-trained, fine-tuned, instruction-tuned or RL-tuned.

HuggingFace Open LLM Leaderboard

Chatbot Arena Leaderboard

The evaluation process used by the Chatbot Arena Leaderboard involves three benchmarks: 1Chatbot Arena, MT-Bench, and MMLU (5-shot). Models compete on Chatbot Arena in randomized settings, answer multi-turn questions on MT-Bench, and undergo a rigorous multitask accuracy test on MMLU (5-shot) across 57 tasks. The leaderboard is meticulous in its calculation of ratings and scores.

Open Source Model Development Challenges

Open-source development for Large Language Models (LLMs) brings numerous advantages, like collaboration, transparency, and innovation. However, building and maintaining these models presents its share of challenges, including:

  1. Cost: Developing and maintaining open-source models can be financially burdensome, particularly for smaller teams and individual developers.

Companies like MosaicML and Databricks are trying to make fine-tuning more accessible through their platforms. Others, like Lambda, are working on reducing GPU costs. Still, cost-related issues persist.

  1. Privacy Issues: Navigating sensitive data collection and storage within open-source models poses privacy hurdles demanding careful management.
  2. Bias/Fairness: Eliminating biases and fostering impartial outcomes in open-source models is a pivotal challenge for achieving equitable AI.
  3. Model Interpretability: Enhancing interpretability of intricate models is vital, particularly as open-source models can resemble "black boxes," obscuring decision-making transparency.
  4. Version Control and Compatibility: The collaborative nature of open-source development introduces hurdles in maintaining version control and ensuring cross-platform compatibility.

Choosing the Right LLM - Best Practices

electing the appropriate Large Language Model (LLM) for your business use case requires a systematic approach. Here's a short step-by-step guide to help you make the right choice:

  1. Identify Your Needs: Define your specific use case and objectives. Are you aiming for content generation, sentiment analysis, translation, or something else?
  2. Analyze Data Requirements: Assess the amount and nature of data available for training and fine-tuning the model. Some LLMs require substantial data for optimal performance.
  3. Consider Model Size: Choose a model size that aligns with your computational resources and performance needs. Larger models might offer better accuracy but come with increased resource demands.
  4. Evaluate Pre-trained Models: Investigate existing pre-trained models that match your use case. Models like GPT-3, BERT, and T5 offer different strengths, such as language understanding or generation.
  5. Customization Flexibility: Determine if the model allows fine-tuning for domain-specific language and nuances. Some models offer greater customization options.
  6. Check Interpretability: Ensure the model provides insights into its decision-making process. Transparent models are crucial for understanding and troubleshooting.
  7. Assess Bias and Fairness: Examine how the model addresses bias in language generation. Consider models that prioritize fairness and inclusivity.
  8. API and Integration: Evaluate the availability and ease of using the model's API. Compatibility with your existing systems is essential for seamless integration.
  9. Resource Requirements: Consider the hardware and computational resources needed to run the model effectively. Choose a model that aligns with your infrastructure.
  10. Test and Validate: Before finalizing, conduct testing and validation to ensure the chosen model performs well on your specific tasks.
  11. Monitor Performance: Regularly assess the model's performance in real-world scenarios and fine-tune if necessary to maintain accuracy and relevance.

What's Next for Open Source LLMs: Summary

Looking ahead, spanning 2023 and beyond, we can expect the open-source LLM landscape flourishing with the regular introduction of new models.

The 11 models that we’ve listed have made powerful language processing accessible, overcoming cost and proprietary hurdles.

However, they also face a multitude of challenges like cost, privacy, bias, and scalability. Users must consider these against benefits like customization, cost savings, and security, compared to proprietary LLMs that offer support but with fees and less flexibility.

Yet, the open-source community is committed to ethical, user-centric models. As technology evolves, these LLMs will progress, driving innovative, collaborative, and responsible AI-driven language processing.

We are excited to see what lies ahead for the AI community and hope you are, too!
