Fine-tuning
Supported Models
A list of all the models available for fine-tuning.
The following models are available to use with our fine-tuning API. Get started with fine-tuning a model!
-
Training Precision Type indicates the precision type used during training for each model.
- AMP (Automated Mixed Precision): AMP allows the training speed to be faster with less memory usage while preserving convergence behavior compared to using float32. Learn more about AMP in this PyTorch blog.
- bf16 (bfloat 16): This uses bf16 for all weights. Some large models on our platform use full bf16 training for better memory usage and training speed.
- For batch sizes of 1, Gradient accumulation 8 is used, so effectively you will get batch size 8 (iteration time is slower).
- Long-context fine-tuning of Llama 3.1 (8B) Reference, Llama 3.1 (70B) Reference, Llama 3.1 Instruct (70B) Reference for context sizes of 32K-131K is only supported using the LoRA method.
- For Llama 3.1 (405B) Fine-tuning, please contact us.
