FlashInfer
3.0Toolkit of acceleration techniques for large language model deployment and serving.
About
FlashInfer is an open toolkit that introduces techniques for accelerating large language model deployment. It provides optimized kernels and runtime solutions for LLM inference and serving — the layer where attention, sampling, and memory movement determine how fast and how cheaply a model can serve users. FlashInfer is aimed at engineers who deploy LLMs and need better throughput and latency than stock inference stacks provide.
Key Features
Pricing & Fees
- Pricing: Not publicly listed on the pages we reviewed; check the official site for current plans.
- Open source: FlashInfer is distributed as open-source kernels for LLM inference, with code available on GitHub under the flashinfer-ai organization.
- Platform availability: The project targets GPU-based deployment of large language models and provides documentation, papers, and release posts on its official site.
Who It's For
FlashInfer is for ML infrastructure engineers running LLM inference at scale, framework developers building serving systems, and researchers who need fast, reproducible kernels for attention and decoding experiments.
