Dub swaps Jev-based AI emoji picker for an Upstash vector index

Dub first built its AI emoji picker with Jev, but feeding the full emoji catalog consumed many input tokens, so it refactored to a simple Upstash vector index and costs became nearly negligible.

Fun fact: We actually built our AI emoji picker @dubdotco with Jev at first, but since we had to feed the entire emoji catalog into Jev, it consumed a lot of input tokens. Refactored to a simple vector index on @upstash vector, and costs became nearly negligible 🤯 Just shipped this to prod – h/t @pedrooladeira 👏
