Shared compatibility

  • Python · JetStream: Python runtime · flashinfer: Python runtime

Choose JetStream if…

  • Tags unique to JetStream: gemma, gpt, inference, jax.
  • * You are working with large language models (LLMs) that require efficient inference on hardware supported by XLA, particularly TPUs.
  • Leaner open-issue backlog (25).

When NOT to use JetStream

  • * If your primary compute platform is not an XLA-compatible device such as TPU; JetStream's current focus is on systems that are supported by XLA.
  • * When you need immediate support for GPUs, since GPU functionality is marked as a future potential enhancement.

Choose flashinfer if…

  • Tags unique to flashinfer: attention, cuda, distributed-inference, jit.
  • Also covers LLM Frameworks.
  • When aiming to deploy large language models efficiently using CUDA capabilities, maximizing GPU utilization with FlashInfer can be advantageous.

When NOT to use flashinfer

  • If the project does not involve large-scale language models or has limited GPU resources, FlashInfer’s specialized features may offer fewer benefits.
  • For those preferring frameworks integrated closely with other deep learning APIs beyond PyTorch, considering alternatives might better align with diverse tooling requirements.
