Choose flashinfer if…
- Tags unique to flashinfer: attention, cuda, distributed-inference, gpu.
- 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.
Choose Star-Attention if…
- Tags unique to Star-Attention: attention-mechanism, large language models.
- For applications requiring handling very large input sequences
- Leaner open-issue backlog (0).
When NOT to use Star-Attention
- If your use case involves short sequence processing only
- In scenarios where traditional attention mechanisms yield adequate results without performance loss
