New benchmark results demonstrate value of Snorkel AI approach to LLM alignment

We have some cool news to share! Snorkel AI ranked 2nd, behind only GPT-4 Turbo, in our recent submission to AlpacaEval 2.0 LLM leaderboard. This benchmark measures the ability of well-known LLMs such as Gemini, Claude 2, Llama 2, Mixtral, etc. to follow general user instructions. This result was achieved with only an open-source 7B parameter model, thanks to Snorkel AI’s state-of-the-art methods for LLM customization.

Snorkel AI has long championed the idea that AI teams can get better results faster by replacing highly manual data annotation with programmatic approaches that more efficiently capture and apply subject matter expertise. Snorkel Flow is our data development platform that helps companies like Wayfair and BNY Mellon to fine-tune and align generative models with these programmatic approaches, and today’s result demonstrates the value of a key component of that technology.

Alignment methods such as reinforcement learning from human feedback (RLHF) and direct process optimization (DPO) are typically used as the last step in LLM development to customize a model to match user preferences. That preference data has historically been collected in the form of manual annotations, which are then used to train a reward model for RLHF. DPO has recently emerged as a more stable and performant alternative that utilizes pairs of annotated responses directly. With programmatic alignment, we use a hybrid approach aimed at getting the best of both worlds. First, users rapidly supervise a custom reward model with programmatic labels generated in Snorkel Flow. Second, that reward model is used in conjunction with the LLM being aligned to create high volumes of high quality pairs for use with DPO. The result is a model that is aligned to your preferences, on your data, without a slow and expensive manual labeling process.

AlpacaEval is a general-purpose benchmark, so an off-the-shelf, general-purpose reward model (we used PairRM) sufficed to achieve this strong result without any additional task-specific programmatic data development. The model was fine-tuned and trained using Microsoft Azure A100 GPUs. Ongoing work includes building on this result with publicly shareable demonstrations of the full programmatic alignment pipeline in more business-specific use cases that are not well-represented by general-purpose benchmarks such as AlpacaEval.
