LLMs' fanciness and increasing intelligence don't change the reality—ultimately, they're just API calls. As such, they suffer from the same problems as API calls, such as throttling, timeouts, and exponential delays. 🔌 ⚡️ ➡️ But you can use clever ways to make LLM calls faster.

"Redis is the fastest vector database, but my dataset is large and I don't want to use big machines with lots of RAM as it is expensive, or having to shard my data with clustering." Fair enough. That's why for use cases like this you should use Redis Flex.
