Performance Improvement - The challenge is to accelerate the token generation speed of a GPT model from 100 tokens in 42 seconds, aiming for a 5x improvement [1] Interview Scenario - The scenario involves an AI Engineer interview at OpenAI, highlighting the importance of understanding optimization techniques beyond simply allocating more GPUs [1]

KV caching speeds up inference by computing the prompt's KV cache before generating tokens.This is exactly why ChatGPT takes longer to generate the first token than the rest.This delay is known as time-to-first-token (TTFT).Improving TTFT is a topic for another day! https://t.co/wYaYa5paNj ...

This is called KV caching!To reiterate, instead of redundantly computing KV vectors of all context tokens, cache them.To generate a token:- Generate QKV vector for the token generated one step before.- Get all other KV vectors from cache.- Compute attention.Check this👇 https://t.co/TvwvdoXJ6m ...
