Snorkel AI is proud to announce a new strategic partnership with Together AI that enables organizations to build custom LLMs on their data in their secure environments. This end-to-end AI development solution spans data development, model training, fine-tuning, and deployment.

“Enterprises today are more interested in GPT-You than GPT-4. They want capable, specialist LLMs that are trained on their data and private to them,” said Snorkel Co-founder and CEO Alex Ratner. “Accomplishing that requires both data-centric operations—which the Snorkel team has been researching and developing for the better part of a decade—and model-centric ones. Together’s training, fine-tuning, and inference cloud is the perfect complement for Snorkel’s data development platform, and we’ve been impressed by their unique technology.”

While publicly-available LLMs yield impressive results on a wide variety of GenAI tasks, their limitations make them an untenable solution for many businesses. Their lack of domain and use-case specialization puts them out of line with enterprise objectives and leaves accuracy on the table. Using the same model as its competitors also prevents a business from taking advantage of the moat that their proprietary data should provide.

Businesses can overcome this challenge by selecting an open source large language model and fine-tuning their own proprietary version of it. Previously, that meant the slow process of building substantial internal tooling and workflows. Now, firms can work with Snorkel and Together to achieve tangible results with business value, faster.

“With Together API, our training, fine-tuning, and inference cloud, every part of the model development process is fully within your business’s control, and you own the weights for your model in the end,” said Together AI Founder and CEO Vipul Ved Prakash. “But training is only half the equation—selecting, labeling, and curating the right data to train on is critical yet one of the biggest stumbling blocks. Snorkel’s track record of innovation and proven enterprise results make them a clear leader, and we’re excited to partner to provide a full-stack solution for AI development.”

Researchers at Snorkel and Together recently collaborated to use the Snorkel Flow data development platform with Together’s APIs to create higher quality instruction tuning datasets for the RedPajama family of open-source large language models. More details on that project will follow in the coming days.
