Puntos de conexión de la API de REST para la inferencia de modelos
Usa la API de REST para enviar una solicitud de finalización de chat a un modelo especificado, con o sin atribución organizativa.
Acerca de la inferencia de GitHub Models
Puedes usar la API de REST para ejecutar solicitudes de inferencia mediante la plataforma GitHub Models.
La API admite:
- Obtener acceso a los modelos principales desde OpenAI, DeepSeek, Microsoft, Llama, etc.
- Ejecutar solicitudes de inferencia basadas en chat con control total sobre los parámetros de muestreo y respuesta.
- Finalización de streaming o sin streaming.
- Seguimiento de uso y atribución de la organización.
Run an inference request attributed to an organization
This endpoint allows you to run an inference request attributed to a specific organization. You must be a member of the organization and have enabled models to use this endpoint.
The token used to authenticate must have the models: read permission if using a fine-grained PAT or GitHub App minted token.
The request body should contain the model ID and the messages for the chat completion request. The response will include either a non-streaming or streaming response based on the request parameters.

Typical usage begins with a chat message for the System role that provides instructions for the behavior of the assistant, followed by alternating messages between the User and Assistant roles. | ||||||||||

role string RequeridoThe chat role associated with this message Puede ser uno de los siguientes: |
content string RequeridoThe content of the message |
frequency_penalty number A value that influences the probability of generated tokens appearing based on their cumulative frequency in generated text. Positive values will make tokens less likely to appear as their frequency increases and decrease the likelihood of the model repeating the same statements verbatim. Supported range is [-2, 2].
max_tokens integer The maximum number of tokens to generate in the completion. The token count of your prompt plus max_tokens cannot exceed the model's context length. For example, if your prompt is 100 tokens and you set max_tokens to 50, the API will return a completion with a maximum of 50 tokens.
modalities array of strings The modalities that the model is allowed to use for the chat completions response. The default modality is text. Indicating an unsupported modality combination results in a 422 error.
Supported values are: text, audio
presence_penalty number A value that influences the probability of generated tokens appearing based on their existing presence in generated text. Positive values will make tokens less likely to appear when they already exist and increase the model's likelihood to output new tokens. Supported range is [-2, 2].
response_format object The desired format for the response.

stop array of strings A collection of textual sequences that will end completion generation.
temperature number The sampling temperature to use that controls the apparent creativity of generated completions. Higher values will make output more random while lower values will make results more focused and deterministic. It is not recommended to modify temperature and top_p for the same completion request as the interaction of these two settings is difficult to predict. Supported range is [0, 1]. Decimal values are supported.

tools array of objects A list of tools the model may request to call. Currently, only functions are supported as a tool. The model may respond with a function call request and provide the input arguments in JSON format for that function.

type string Valor: function
top_p number An alternative to sampling with temperature called nucleus sampling. This value causes the model to consider the results of tokens with the provided probability mass. As an example, a value of 0.15 will cause only the tokens comprising the top 15% of probability mass to be considered. It is not recommended to modify temperature and top_p for the same request as the interaction of these two settings is difficult to predict. Supported range is [0, 1]. Decimal values are supported.
