Available Models - OneFirewall Documentation

The Secure AI Gateway provides a unified interface to multiple top-tier AI models. You can specify the model using the model parameter in your API requests.

Model ID	Provider	Description
`openai/gpt-4o-mini`	OpenAI	Fast and cost-effective for simple tasks
`openai/gpt-4o`	OpenAI	Most capable OpenAI model
`openai/gpt-5.2`	OpenAI	The best model for coding and agentic tasks
`google/gemini-2.5-flash`	Google	Fastest and most cost-efficient multimodal model
`google/gemini-2.5-pro`	Google	Most capable Google model with advanced reasoning
`xai/grok-4-1-fast-reasoning`	xAI / Reasoning	Fast reasoning and problem solving
`deepseek/deepseek-reasoner`	DeepSeek	Advanced reasoning model
`deepseek/deepseek-chat`	DeepSeek	Fast and efficient chat model (V3)
`openai/o1`	OpenAI	Advanced reasoning and problem-solving
`minimax/MiniMax-M2.1`	MiniMax	Reasoning model with tool support

Model Selection

To use a specific model, pass its ID in the request body:

{
  "model": "deepseek/deepseek-reasoner",
  "messages": [...]
}

Capabilities Mapping

Feature	Support
Text Generation	All models
Visual Input (Vision)	`openai/gpt-4o`, `openai/gpt-5.2`, `google/gemini-2.5-pro`, `xai/grok-4-1-fast-reasoning`

API Endpoints (OpenAI Compatible)

The Secure AI Gateway mimics the OpenAI API structure, meaning standard clients can fetch available models dynamically.

`GET /api/v1/models`

Retrieves a list of all currently supported models in the standard OpenAI response format. Example Request:

curl http://localhost:3000/api/v1/models \
  -H "Authorization: Bearer YOUR_API_KEY_HERE"

`GET /api/v1/models/[model]`

Retrieves information about a specific model. Model IDs with slashes (e.g. openai/gpt-4o) are fully supported. Example Request:

curl http://localhost:3000/api/v1/models/openai/gpt-4o \
  -H "Authorization: Bearer YOUR_API_KEY_HERE"
