Developer abhijithneil hit a wall while benchmarking a 31B Gemma model: flashinfer's attention backend didn't support 512 headdim. He forked the vLLM project, applied a custom patch, and managed to break through the benchmark speed ceiling. His takeaway: there's still a huge amount of work to be done in inference frameworks.
