Give any API model a memory.
Point your OpenAI-compatible client at one endpoint. ModelRouters adds a persistent, editable memory layer — your model remembers across sessions, stays under context limits, and costs less. Bring your own key, or use a hosted model.

https://api.modelrouters.net/v1 https://api.modelrouters.net/v1/chat/completionsWorks with the OpenAI SDK, LangChain, or plain curl — just change the base URL and use your ModelRouters key.
How it works
Point to one endpoint
Set your OpenAI-compatible client's base URL to https://api.modelrouters.net/v1. No SDK swap, no rewrite.
Bring your key, or use hosted
Connect DeepSeek or another direct provider, name your models, and route them for free — or use a hosted model with credits.
Memory does the rest
Facts are distilled, injected, and compressed as the chat grows. It's yours — view, edit, or delete any of it, any time.
Why a memory layer
The model stays the same. What changes is that it remembers.
Persistent memory
Your model remembers across sessions — not just within a single context window.
Context compression
Engages before you hit the limit, keeping long chats coherent and cutting token cost.
Yours to edit
User-visible, editable memory and chat history. No black box — read it, change it, delete it.
Encrypted
Per-account encryption at rest. Automated-only handling — no human review of your content.
Any model
Works with any OpenAI-compatible endpoint. Switch providers without losing your memory.
One key, one endpoint
A single ModelRouters key routes to every provider you connect. Drop-in and streaming.
Supported models
Use every provider hosted or bring your own key. Every model gets the same memory layer over the same OpenAI-compatible API.
