  • A new benchmark for multimodal LLMs that focuses on core visual perception abilities that other benchmarks don’t cover.
  • Most tasks in this benchmark can be solved by humans in just a “blink”, but current multimodal LLMs struggle - while humans get 95.70% accuracy on average, GPT-4V and Gemini only achieve accuracies of 51.26% and 45.72%.

Learn Your Reference Model for Real Good Alignment

  • Introduces a new Direct Preference Optimization (DPO) algorithm called Trust Region DPO (TR-DPO), which updates the reference policy (commonly the Supervised Fine Tuning model) during training.
  • Outperforms DPO by up to 19%.

Megalodon: Efficient LLM Pretraining and Inference with Unlimited Context Length

  • Introduces Megalodon, a neural architecture for efficient sequence modeling with unlimited context length.
  • Based on Mega.
  • Comparable to Llama-2B and 13B.
  • Code

HF medical leaderboard

  • LLMs have shown promise in healthcare settings, such as medical Q/A. But the stakes are much higher when using an LLM based tool in a clinical setting - mistakes can be harmful or fatal.
  • The benchmark covers general medical knowledge, clinical knowledge, anatomy, genetics, and more, to help bridge the gap between LLM potential for medical use cases and proper evaluation.

  • Backend uses Eleuther AI Language Model Evaluation Harness.

HF coding leaderboard

  • A new benchmark for assessing LLM code generation capabilities
  • Contains a standard code generation task, as well as more difficult tasks for more robust, next-generation AI assistant capability testing:

    1. Code Generation: Standard task to generate a correct solution to a natural language description.
    2. Self Repair. Generate a code fix given error feedback.
    3. Code Execution: Predict the output of a program on a given input.
    4. Test Output Prediction: Same as Code Execution, but the program is not actually implemented, only described.
