Model tuningPreview
Use the fine-tuned YandexGPT Lite and classifiers to make responses more accurately reflect the specifics of your tasks.
Invoking functions
Work with external tools and APIs to, for example, form a function call to find out about the last order or product availability, and then use this data in a chatbot’s response.
YandexGPT-based classifiers
Solve tasks like determining the tone of reviews or sorting requests. Just formulate the rules, describe the classes, and the classifier will be ready to work.
Text vectorization
Embeddings select vectors for words with similar meanings, and can be used to compare and contrast texts, or to organize a knowledge base search.
