Atlas Cloud

Atlas Cloud is an AI API aggregation platform that provides unified access to 300+ AI models through one API key and billing account. Its LLM chat API is OpenAI-compatible, so it integrates with promptfoo using the same request shape as the OpenAI chat provider.

Setup

Create an API key in the Atlas Cloud dashboard.
Set the ATLASCLOUD_API_KEY environment variable:

export ATLASCLOUD_API_KEY=your_api_key_here

You can also pass apiKey directly in the provider config, but using an environment variable is recommended.

Basic Configuration

promptfooconfig.yaml
# yaml-language-server: $schema=https://promptfoo.dev/config-schema.json
providers:
  - id: atlascloud:deepseek-ai/DeepSeek-V3-0324
    config:
      temperature: 0.7
      max_tokens: 500

  - id: atlascloud:qwen/qwen3-32b
    config:
      temperature: 0.2

prompts:
  - 'Answer clearly and concisely: {{question}}'

tests:
  - vars:
      question: 'What is the capital of France?'
    assert:
      - type: contains
        value: 'Paris'

By default, the Atlas Cloud provider sends chat requests to https://api.atlascloud.ai/v1.

Configuration Options

Atlas Cloud supports the standard OpenAI chat options already available in promptfoo, including:

temperature
max_tokens
top_p
presence_penalty
frequency_penalty
stop
response_format
tools
tool_choice

For the full shared option set, see the OpenAI provider documentation.

Custom Base URL or API Key Variable

If you route Atlas Cloud through a proxy or internal gateway, override apiBaseUrl. You can also instruct promptfoo to read the Bearer token from a different environment variable by setting apiKeyEnvar.

promptfooconfig.yaml
providers:
  - id: atlascloud:deepseek-ai/DeepSeek-V3-0324
    config:
      apiBaseUrl: https://proxy.example.com/atlas/v1
      apiKeyEnvar: MY_ATLASCLOUD_TOKEN
      temperature: 0.7

Precedence is:

config.apiBaseUrl if provided, otherwise Atlas Cloud's default https://api.atlascloud.ai/v1
config.apiKeyEnvar if provided, otherwise ATLASCLOUD_API_KEY

Model Examples

Atlas Cloud's catalog changes over time. You should use the exact model ID returned by GET /v1/models. For example, this provider was verified against live Atlas Cloud model IDs such as deepseek-ai/DeepSeek-V3-0324 and qwen/qwen3-32b.

providers:
  - atlascloud:deepseek-ai/DeepSeek-V3-0324
  - atlascloud:qwen/qwen3-32b
  - atlascloud:moonshotai/Kimi-K2-Instruct

Use the exact model ID shown in the Atlas Cloud model library or docs.
