Large language models (LLMs)

Leading ML teams are quickly capitalizing on the latest advances in large language models (LLMs) as a powerful starting point for their NLP use cases. However, they often realize that these base models need to be specifically tailored for their use case and have to be retrained with contextual annotated data in order to build production-grade AI.


Learn how ML teams in industries such as healthcare, retail, and beyond can enable breakthroughs faster with Labelbox, whether it’s summarizing medical research papers, categorizing customer sentiment, or delivering chatbots with human-like interactions.

Powering intelligent applications from leading enterprises

Labeling apps for reinforcement learning with human feedback (RLHF)

Use off-the-shelf labeling apps or build custom ones with the Labelbox SDK for reinforcement learning with human feedback (RLHF) use cases. Advance state-of-the-art language models that align with human preferences so that your applications can best understand what your customers and users want.


Fine-tune your pre-trained LLM models to output human-like responses faster with a complete set of labeling editors that can be tailored for summarization, code completion, sentiment detection, and beyond.

Label faster than ever with automation

Label faster than ever with automation

Achieve up to 65% in labeling efficiency gains with model-assisted labeling – use your large language model to pre-label data, and let your team of labelers focus on corrective actions to generate ground truth so they don’t need to start from scratch.


Save time by uploading your foundational model predictions directly into your annotation experience. Simply pick any foundational model (GPT, BERT, etc) including ones that have already been re-trained which are closest to your use case (KeyBERT, finBERT, LEGAL-BERT).
