OpenAI (or Compatible) Language Models

To use a language model hosted on OpenAI (or compatible), specify the openai path in the from field.

For a specific model, include it as the model ID in the from field (see example below). The default model is gpt-4o-mini.

models:
  - from: openai:gpt-4o-mini
    name: openai_model
    params:
      openai_api_key: ${ secrets:OPENAI_API_KEY } # Required for official OpenAI models
      tools: auto # Optional. Connect the model to datasets via SQL query/vector search tools
      system_prompt: "You are a helpful assistant." # Optional.

      # Optional parameters
      endpoint: https://api.openai.com/v1 # Override to use a compatible provider (i.e. NVidia NIM)
      openai_org_id: ${ secrets:OPENAI_ORG_ID }
      openai_project_id: ${ secrets:OPENAI_PROJECT_ID }

      # Override default chat completion request parameters
      openai_temperature: 0.1
      openai_response_format: { "type": "json_object" }

Configuration

from

The from field takes the form openai:model_id where model_id is the model ID of the OpenAI model, valid model IDs are found in the {endpoint}/v1/models API response.

Example:

curl -H "Authorization: Bearer $OPENAI_API_KEY" https://api.openai.com/v1/models

{
  "object": "list",
  "data": [
    {
      "id": "gpt-4o-mini",
      "object": "model",
      "created": 1727389042,
      "owned_by": "system"
    },
...
}

name

The model name. This will be used as the model ID within Spice and Spice's endpoints (i.e. http://localhost:8090/v1/models). This can be set to the same value as the model ID in the from field.

params

Param	Description	Default
endpoint	The OpenAI API base endpoint. Can be overridden to use a compatible provider (i.e. Nvidia NIM).	https://api.openai.com/v1
tools	Which tools should be made available to the model. Set to auto to use all available tools.	-
system_prompt	An additional system prompt used for all chat completions to this model.	-
openai_api_key	The OpenAI API key.	-
openai_org_id	The OpenAI organization ID.	-
openai_project_id	The OpenAI project ID.	-
openai_temperature	Set the default temperature to use on chat completions.	-
openai_response_format	An object specifying the format that the model must output, see structured outputs.	-

Supported OpenAI Compatible Providers

Spice supports several OpenAI compatible providers. Specify the appropriate endpoint in the params section.

Azure OpenAI

Follow Azure AI Models instructions.

Groq

Groq provides OpenAI compatible endpoints. Use the following configuration:

models:
  - from: openai:llama3-groq-70b-8192-tool-use-preview
    name: groq-llama
    params:
      endpoint: https://api.groq.com/openai/v1
      openai_api_key: ${ secrets:SPICE_GROQ_API_KEY }

NVidia NIM

NVidia NIM models are OpenAI compatible endpoints. Use the following configuration:

models:
  - from: openai:my_nim_model_id
    name: my_nim_model
    params:
      endpoint: https://my_nim_host.com/v1
      openai_api_key: ${ secrets:SPICE_NIM_API_KEY }

View the Spice cookbook for an example of setting up NVidia NIM with Spice here.

Parasail

Parasail also offers OpenAI compatible endpoints. Use the following configuration:

models:
  - from: openai:parasail-model-id
    name: parasail_model
    params:
      endpoint: https://api.parasail.com/v1
      openai_api_key: ${ secrets:SPICE_PARASAIL_API_KEY }

Refer to the respective provider documentation for more details on available models and configurations.
