Works with any model — your choice, swap anytime.
OpenAI, Claude, Gemini, or open models — ULTRAMEMORY sits in front of all of them. Your memory belongs to you, not to a model vendor, so you can switch whenever you want and keep everything you've remembered.

The model is a choice — not a cage.
Tie your AI's memory to one model vendor and you're stuck — switching means starting over and losing everything it learned. We keep memory separate from the model, so the model is a choice you can change, not a cage.
Works with the models you already use.

Your memory is the constant. The model is a plug-in part.
Your agents talk to ULTRAMEMORY — the durable memory layer — and ULTRAMEMORY talks to whichever model sits in the slot. The memory stays put while the model chip changes.
Your agents → ULTRAMEMORY → a swappable model slot. Rotate through OpenAI, Claude, Gemini, or an open model — the memory layer stays put.

Different models for different jobs.
Use different models for different jobs, spread load across several providers, and fail over automatically if one has a bad day — without touching your memory or your code.
Choose per task
Use a fast model for routine calls and a stronger one for the hard jobs — the same shared memory backs them all.
Balance across providers
Spread load across several providers so no single one becomes a bottleneck.
Auto-failover
If a provider has a bad day, requests roll over automatically — without touching your memory or your code.
One shared memory works the same no matter which model each agent runs — heterogeneous tools, one memory.
Change your mind? Nothing is lost.
Change your mind on a model? Switch in your settings. If it changes how memories are indexed, we quietly re-process them in the background — nothing is lost, nothing breaks.

Quality is in the ranking, not just the model.
At today's quality tier, results depend more on how memories are ranked than on which model embeds them — and ranking is our strength. Want the last few points? Switch on a premium model per workspace.
