# OpenRouterLLMNode - ComfyUI Built-in Node Documentation
> The OpenRouter LLM node sends a text prompt to a curated set of popular language models available through the OpenRouter service and returns the generated text response.
The OpenRouter LLM node sends a text prompt to a curated set of popular language models available through the OpenRouter service and returns the generated text response. It supports models from Anthropic (Claude), OpenAI (GPT), Google (Gemini), xAI (Grok), DeepSeek, Qwen, Mistral, Z.AI (GLM), Moonshot (Kimi), and Perplexity Sonar, and can optionally include images or videos as reference inputs in the request.
## Inputs
When a model is selected in the `model` selector, the node shows model-specific widgets on top of the common inputs — reasoning effort, web search size, and/or reference media slots — depending on the capabilities of the chosen model.

**Notes:**
* **Available models:** The available model options are dynamically built and include models with different capabilities. The full list of 34 models is:
* Anthropic: `anthropic/claude-opus-5`, `anthropic/claude-opus-4.8`, `anthropic/claude-opus-4.7`, `anthropic/claude-fable-5`, `anthropic/claude-sonnet-5`, `anthropic/claude-haiku-4.5`
* OpenAI: `openai/gpt-5.6-sol-pro`, `openai/gpt-5.6-sol`, `openai/gpt-5.6-terra-pro`, `openai/gpt-5.6-terra`, `openai/gpt-5.6-luna-pro`, `openai/gpt-5.6-luna`, `openai/gpt-5.5-pro`, `openai/gpt-5.5`
* Google: `google/gemini-3.5-flash`
* xAI: `x-ai/grok-4.5`, `x-ai/grok-4.20`, `x-ai/grok-4.3`
* DeepSeek: `deepseek/deepseek-v4-pro`, `deepseek/deepseek-v4-flash`, `deepseek/deepseek-v3.2`
* Qwen: `qwen/qwen3.6-max-preview`, `qwen/qwen3.6-plus`, `qwen/qwen3.6-flash`
* Mistral: `mistralai/mistral-large-2512`, `mistralai/mistral-medium-3-5`
* Z.AI: `z-ai/glm-4.6`, `z-ai/glm-5`
* Moonshot: `moonshotai/kimi-k3`, `moonshotai/kimi-k2.6`, `moonshotai/kimi-k2-thinking`
* Perplexity: `perplexity/sonar-pro`, `perplexity/sonar-reasoning-pro`, `perplexity/sonar-deep-research`
* **Image and video constraints:** The maximum number of reference images and videos depends on the selected model. The node raises an error if the total number of images or videos provided exceeds the model's limit. Models without image or video support do not show the corresponding reference slots.
* **Reasoning behavior:** When `reasoning_effort` is set to anything other than "off", the request asks the provider to reason internally without returning the reasoning trace.
* **Seed behavior:** The `seed` parameter has a "control\_after\_generate" behavior, meaning it can be set to automatically change (e.g., randomize, increment, or fixed) after each node execution, depending on the user's widget settings.
* **System prompt:** The `system_prompt` parameter is optional and is marked as an advanced parameter in the user interface.
* **Error cases:** The node raises an error if the prompt is empty after trimming whitespace, if OpenRouter returns an error, if the selected model refuses to respond, or if the response contains no choices or message. A price badge on the node shows an approximate cost estimate per 1K tokens based on the selected model.
## Outputs
| Output Name | Description | Data Type |
| ----------- | ------------------------------------------------------ | --------- |
| `output` | The generated text response from the OpenRouter model. | STRING |
