PentAGI can run on it via the custom LLM provider — see [Atlas Cloud (OpenAI-compatible)](#atlas-cloud-openai-compatible).

 This setting is required by some LLM providers (e.g., Moonshot) that return errors like "thinking is enabled but reasoning_content is missing in assistant tool call message" when reasoning content is not included in multi-turn conversations. Enable this setting if your provider requires reasoning content to be preserved.
 
+#### Atlas Cloud (OpenAI-compatible)
+
+[Atlas Cloud](https://www.atlascloud.ai/?utm_source=github&utm_medium=link&utm_campaign=pentagi) is OpenAI-compatible, so it plugs into PentAGI through the `LLM_SERVER_*` custom-provider variables — a single endpoint for DeepSeek, Qwen, GLM, Kimi, MiniMax, and more.

+```bash
+LLM_SERVER_URL=https://api.atlascloud.ai/v1
+LLM_SERVER_KEY=your_atlascloud_api_key
+LLM_SERVER_MODEL=deepseek-ai/deepseek-v4-pro
+LLM_SERVER_PROVIDER=openai
+```
+
+`deepseek-ai/deepseek-v4-pro` is a reasoning model and works with PentAGI's default structured reasoning format (`LLM_SERVER_LEGACY_REASONING=false`). Any other Atlas chat model id can be used the same way.

 ### Ollama Provider Configuration
 
 PentAGI supports Ollama for both local LLM inference (zero-cost, enhanced privacy) and Ollama Cloud (managed service with free tier).
