With the model layer becoming commoditized, your context should travel seamlessly across models whether you are using OpenRouter or some other model aggregator.
FastRecall offers a simple API that stores your context cheaply and efficiently. In fact, we are so cheap that recalls are entirely free, with generous plans starting at only $2/month!
If you use the same model again, FastRecall respects provider caching to save you inference costs. We also have SOTA model-free compaction of context with FlashCompact, in case you don't need full-fidelity context.
Hopefully this is useful for some of your projects. Let me know what you think!
