Reinforcement Learning 
from Human Feedback (RLHF)

Train a safer, more accurate model by aligning with human preferences.

Developing RLHF-trained 
language models with Toloka

  • Adapt a language model to 
    your business applications 
    by fine-tuning with human 
  • Automate RLHF flows for 
    continuous model training 
    that aligns model output 
    with human values.
  • Get on-demand access to 
    Toloka's global crowd and 
    capture human preferences 
    at any scale.
  • Use negative examples 
    in your model training.
