Faster AI starts with semantic caching
Fastly AI Accelerator
Get better AI performance with intelligent caching that understands your data. Fastly's AI Accelerator boosts the performance of popular LLMs like ChatGPT and Google Gemini by 9x. No rebuild necessary, just one line of code.
Why your AI workloads need a caching layer
AI workloads can be more than an order of magnitude slower than non-LLM processing. Your users feel the difference from tens of milliseconds to multiple seconds — and over thousands of requests your servers feel it too.
Semantic caching maps queries to concepts as vectors, caching answers to questions no matter how they’re asked. It’s recommended best practice from major LLM providers, and AI Accelerator makes semantic caching easy.

Take the stress out of using LLMs and build more efficient applications
Fastly AI Accelerator reduces API calls and bills with intelligent, semantic caching.
Improve performance
Fastly helps make AI APIs fast and reliable by reducing the number of requests and request times with semantic caching.
Reduce costs
Slash costs by reducing upstream API usage, serving the content directly from Fastly cache.
Increase developer productivity
Save valuable developer time and avoid reinventing the wheel by caching AI responses and leveraging the power of the Fastly platform.
