Pollinations Chat Model (Sub-node)

A sub-node designed for use with AI Agents and LLM Chains in n8n. This node provides a language model that can be connected to AI workflow nodes.

Use Cases

• Connect to AI Agent nodes for conversational AI workflows
• Use with LLM Chain nodes for text processing pipelines
• Build custom AI assistants using n8n's AI capabilities

Parameters

Parameter	Required	Description
Model	Yes	The chat model to use (loaded dynamically from API)
Temperature	Yes	Controls randomness: 0 = deterministic, 2 = very creative (default: 1)

Advanced Options

Option	Default	Description
Max Tokens	0	Maximum tokens in response (0 = model default)
Top P	1	Nucleus sampling parameter (0-1)
Frequency Penalty	0	Reduce repetition of token sequences (-2 to 2)
Presence Penalty	0	Increase likelihood of new topics (-2 to 2)
Timeout	60000	Request timeout in milliseconds

How to Use

1. Add an AI Agent or LLM Chain node to your workflow
2. Add a Pollinations Chat Model node
3. Connect the Chat Model output to the Agent/Chain model input
4. Configure your Pollinations API credentials
5. Select a model and adjust parameters as needed

Credentials

To use this node, you need a Pollinations API key.

Creating an API Key

1. Go to enter.pollinations.ai
2. Sign up or log in to your account
3. Navigate to API Keys section
4. Click Create API Key
5. Configure your key:
   • Name: Give your key a descriptive name (e.g., "n8n Integration")
   • Type: Choose between Publishable (pk_) or Secret (sk_)
   • Model Access: Select which models this key can use (see below)
6. Copy the generated key

Configuring Model Access

When creating an API key, you can restrict which models the key has access to. This is useful for:

• Cost control: Limit access to expensive models
• Security: Restrict capabilities of shared keys
• Organization: Create keys for specific use cases

The node automatically filters the model dropdown to show only the models your API key has permission to use. If you don't see a model you expect, check your key's model permissions at enter.pollinations.ai.

Setting up in n8n

1. In n8n, go to Credentials
2. Click Add Credential
3. Search for Pollinations API
4. Paste your API key
5. Click Save

API Key Types

Type	Prefix	Use Case	Rate Limits
Publishable	pk_	Client-side apps, testing	IP-based rate limiting
Secret	sk_	Server-side, production	No rate limits, can spend Pollen

Important: Secret keys (sk_) should never be exposed in client-side code. Use them only in server environments like n8n.

Available Models

Models are loaded dynamically from the Pollinations API, ensuring you always have access to the latest available models.

Image Models

Common models include Flux, Turbo, GPT Image, Kontext, Seedream, and more.

Text Models

Common models include OpenAI GPT-5, Claude, Gemini, DeepSeek, Mistral, and more.

Example Usage

Basic Image Generation

1. Add a Pollinations node to your workflow
2. Select Generate Image operation
3. Select your Pollinations API credentials
4. Enter a prompt like "A beautiful sunset over mountains"
5. Select a model (e.g., Flux)
6. Execute the node

The output will be a binary image that you can:

• Save to disk using the Write Binary File node
• Upload to cloud storage (S3, Google Drive, etc.)
• Send via email or messaging platforms
• Process with other image manipulation nodes

Image-to-Image with Reference

1. Add a Pollinations node to your workflow
2. Select Generate with Reference operation
3. Select your Pollinations API credentials
4. Enter a prompt like "Transform into a watercolor painting"
5. Enter the URL of your reference image
6. Select a model (e.g., Kontext)
7. Execute the node

Use cases for reference images:

• Style transfer: Apply artistic styles to existing images
• Consistent characters: Generate variations of a character for tutorials
• Image editing: Modify specific aspects of an image with text prompts
• Product variations: Create different versions of product images

Basic Text Generation

1. Add a Pollinations node to your workflow
2. Select Generate Text operation
3. Select your Pollinations API credentials
4. Enter a prompt like "Explain quantum computing in simple terms"
5. Optionally add a system prompt to define AI behavior
6. Select a model (e.g., OpenAI)
7. Execute the node

The output will be a JSON object with the generated text and metadata.

AI Agent Integration

1. Add an AI Agent node to your workflow
2. Add a Pollinations Chat Model node
3. Connect the Chat Model to the Agent's model input
4. Configure your Pollinations API credentials on the Chat Model
5. Select a model (e.g., OpenAI, Claude, or DeepSeek)
6. Add tools to your Agent as needed
7. Execute the workflow

This setup allows you to build conversational AI assistants powered by Pollinations models.
