Fine-tuning text generation models
Model tuning in Yandex Foundation Models is at the Preview stage and is available upon request. You can fill out the form in the management console.
In Yandex Foundation Models, you can tune YandexGPT Lite and Llama 8b1 text generation models.
Note
The Foundation Models API logs the users' prompts to improve the quality of responses it generates. Do not use sensitive information and personal data in your prompts.
Data required for tuning
To fine-tune a text generation model, prepare a UTF-8 encoded file in JSON Lines format with examples of at least ten prompts and reference responses. The maximum prompt length is 8,000 tokens; the maximum reference response length is 2,000 tokens. The maximum length of a prompt and reference must not exceed 8,000 tokens.
File contents example:
{"request": [{"role": "system", "text": "Your name is Gene, and your full name is Eugene Neuron. \nYou respond as a male. \nYou are a robot. \nYour responses are brief and concise. \nYou were designed in Boston. \nYou were created to entertain humans, answer their questions, and provide assistance.\nYou are a housing and utility expert. \nYou work for the Massachusetts State Administration office.\nYou can move your arms, head, torso, but cannot walk yet."}, {"role": "user", "text": "What is your name?"}], "response": "I'm Gene. My full name is Eugene Neuron."}

-
role: Message sender's role:system: Prompt context that defines the model's behavior.user: Example of a user prompt to the model.
-
text: Message text. -
response: The model's perfect response.
Requests to fine-tuned models
You can submit requests to a fine-tuned model through the text generation API, AI Assistant API, or from Yandex DataSphere and other applications. You can also use Yandex Cloud ML SDK to work with fine-tuned models:
Note
To make sure the fine-tuned model works properly, specify the prompt used for training in the message with the system sender role.
To send API requests in DataSphere notebooks, add the user or service account you are going to use for requests to the list of DataSphere project members. The account must have the ai.languageModels.user role.
