supermemory Infinite Chat is a powerful solution that gives your chat applications unlimited contextual memory. It works as a transparent proxy in front of your existing LLM provider, intelligently managing long conversations without requiring any changes to your application logic.

Unlimited Context

No more token limits - conversations can extend indefinitely

Zero Latency

Transparent proxying with negligible overhead

Cost Efficient

Save up to 70% on token costs for long conversations

Provider Agnostic

Works with any OpenAI-compatible endpoint

Getting Started

To use the Infinite Chat endpoint, you need to:

1. Get a supermemory API key

Head to supermemory’s Developer Platform built to help you monitor and manage every aspect of the API.

Done! You can now use your API key to authenticate requests to the supermemory API.

Next up, let’s add your first memory.

2. Add supermemory in front of any OpenAI-Compatible API URL

import OpenAI from "openai";

/**
 * Initialize the OpenAI client with supermemory proxy
 * @param {string} OPENAI_API_KEY - Your OpenAI API key
 * @param {string} SUPERMEMORY_API_KEY - Your supermemory API key
 * @returns {OpenAI} - Configured OpenAI client
 */
const client = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
  baseURL: "https://api.supermemory.ai/v3/https://api.openai.com/v1",
  headers: {
    "x-api-key": process.env.SUPERMEMORY_API_KEY,
  },
});

How It Works

1

Transparent Proxying

All requests pass through supermemory to your chosen LLM provider with zero latency overhead.

2

Intelligent Chunking

Long conversations are automatically broken down into optimized segments using our proprietary chunking algorithm that preserves semantic coherence.

3

Smart Retrieval

When conversations exceed token limits (20k+), supermemory intelligently retrieves the most relevant context from previous messages.

4

Automatic Token Management

The system intelligently balances token usage, ensuring optimal performance while minimizing costs.

Performance Benefits

Pricing

Free Tier

100k tokens stored at no cost

Standard Plan

$20/month fixed cost after exceeding free tier

Usage-Based

Each thread includes 20k free tokens, then $1 per million tokens thereafter

Error Handling

supermemory is designed with reliability as the top priority. If any issues occur within the supermemory processing pipeline, the system will automatically fall back to direct forwarding of your request to the LLM provider, ensuring zero downtime for your applications.

Each response includes diagnostic headers that provide information about the processing:

HeaderDescription
x-supermemory-conversation-idUnique identifier for the conversation thread
x-supermemory-context-modifiedIndicates whether supermemory modified the context (“true” or “false”)
x-supermemory-tokens-processedNumber of tokens processed in this request
x-supermemory-chunks-createdNumber of new chunks created from this conversation
x-supermemory-chunks-deletedNumber of chunks removed (if any)
x-supermemory-docs-deletedNumber of documents removed (if any)

If an error occurs, an additional header x-supermemory-error will be included with details about what went wrong. Your request will still be processed by the underlying LLM provider even if supermemory encounters an error.

Rate Limiting

Currently, there are no rate limits specific to supermemory. Your requests are subject only to the rate limits of your underlying LLM provider.
