| Args: | |
| model (str): The requested model, such as qwen-long | |
| messages (list): The generation messages. | |
| examples: | |
| [{'role': 'user', | |
| 'content': 'The weather is fine today.'}, | |
| {'role': 'assistant', 'content': 'Suitable for outings'}] | |
| stream(bool, `optional`): Enable server-sent events | |
| (ref: https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events) # noqa E501 # pylint: disable=line-too-long | |
| the result will back partially[qwen-turbo,bailian-v1]. | |
| temperature(float, `optional`): Used to control the degree | |
| of randomness and diversity. Specifically, the temperature | |
| value controls the degree to which the probability distribution | |
| of each candidate word is smoothed when generating text. | |
| A higher temperature value will reduce the peak value of | |
| the probability, allowing more low-probability words to be | |
| selected, and the generated results will be more diverse; | |
| while a lower temperature value will enhance the peak value | |
| of the probability, making it easier for high-probability | |
| words to be selected, the generated results are more | |
| deterministic. | |
| top_p(float, `optional`): A sampling strategy, called nucleus | |
| sampling, where the model considers the results of the | |
| tokens with top_p probability mass. So 0.1 means only | |
| the tokens comprising the top 10% probability mass are | |
| considered. | |
| top_k(int, `optional`): The size of the sample candidate set when generated. # noqa E501 # pylint: disable=line-too-long | |
| For example, when the value is 50, only the 50 highest-scoring tokens # noqa E501 | |
| in a single generation form a randomly sampled candidate set. # noqa E501 | |
| The larger the value, the higher the randomness generated; # noqa E501 | |
| the smaller the value, the higher the certainty generated. # noqa E501 | |
| The default value is 0, which means the top_k policy is # noqa E501 | |
| not enabled. At this time, only the top_p policy takes effect. # noqa E501 | |
| stop(list[str] or list[list[int]], `optional`): Used to control the generation to stop # noqa E501 # pylint: disable=line-too-long | |
| when encountering setting str or token ids, the result will not include # noqa E501 | |
| stop words or tokens. | |
| max_tokens(int, `optional`): The maximum token num expected to be output. It should be # noqa E501 # pylint: disable=line-too-long | |
| noted that the length generated by the model will only be less than max_tokens, # noqa E501 # pylint: disable=line-too-long | |
| not necessarily equal to it. If max_tokens is set too large, the service will # noqa E501 # pylint: disable=line-too-long | |
| directly prompt that the length exceeds the limit. It is generally # noqa E501 | |
| not recommended to set this value. | |
| repetition_penalty(float, `optional`): Used to control the repeatability when generating models. # noqa E501 # pylint: disable=line-too-long | |
| Increasing repetition_penalty can reduce the duplication of model generation. # noqa E501 # pylint: disable=line-too-long | |
| 1.0 means no punishment. | |
| api_key (str, optional): The api api_key, can be None, | |
| if None, will get by default rule. | |
