Image Source

• Public: Kaito maintainers manage the lifecycle of the inference service images that contain model weights. The images are available in Microsoft Container Registry (MCR).

Usage

The inference service endpoint is /chat.

Basic example

curl -X POST "http://<SERVICE>:80/chat" -H "accept: application/json" -H "Content-Type: application/json" -d '{"prompt":"YOUR_PROMPT_HERE"}'

Example with full configurable parameters

curl -X POST \

Parameters

• prompt: The initial text provided by the user, from which the model will continue generating text.
• return_full_text: If False only generated text is returned, else full text is returned.
• clean_up_tokenization_spaces: True/False, determines whether to remove potential extra spaces in the text output.
• prefix: Prefix added to the prompt.
• handle_long_generation: Provides strategies to address generations beyond the model's maximum length capacity.
• max_length: The maximum total number of tokens in the generated text.
• min_length: The minimum total number of tokens that should be generated.
• do_sample: If True, sampling methods will be used for text generation, which can introduce randomness and variation.
• early_stopping: If True, the generation will stop early if certain conditions are met, for example, when a satisfactory number of candidates have been found in beam search.
• num_beams: The number of beams to be used in beam search. More beams can lead to better results but are more computationally expensive.
• num_beam_groups: Divides the number of beams into groups to promote diversity in the generated results.
• diversity_penalty: Penalizes the score of tokens that make the current generation too similar to other groups, encouraging diverse outputs.
• temperature: Controls the randomness of the output by scaling the logits before sampling.
• top_k: Restricts sampling to the k most likely next tokens.
• top_p: Uses nucleus sampling to restrict the sampling pool to tokens comprising the top p probability mass.
• typical_p: Adjusts the probability distribution to favor tokens that are "typically" likely, given the context.
• repetition_penalty: Penalizes tokens that have been generated previously, aiming to reduce repetition.
• length_penalty: Modifies scores based on sequence length to encourage shorter or longer outputs.
• no_repeat_ngram_size: Prevents the generation of any n-gram more than once.
• encoder_no_repeat_ngram_size: Similar to no_repeat_ngram_size but applies to the encoder part of encoder-decoder models.
• bad_words_ids: A list of token ids that should not be generated.
• num_return_sequences: The number of different sequences to generate.
• output_scores: Whether to output the prediction scores.
• return_dict_in_generate: If True, the method will return a dictionary containing additional information.
• pad_token_id: The token ID used for padding sequences to the same length.
• eos_token_id: The token ID that signifies the end of a sequence.
• forced_bos_token_id: The token ID that is forcibly used as the beginning of a sequence token.
• forced_eos_token_id: The token ID that is forcibly used as the end of a sequence when max_length is reached.
• remove_invalid_values: If True, filters out invalid values like NaNs or infs from model outputs to prevent crashes.
