I said speed was great, Cerebas and Groq can provide better performance, likewise Fast versions of Cursor's Composer and Claude.

The reported speed like benchmarks is only a reported number on paper, we'll see how it holds up in real world usage, so far OpenRouter is only reporting 73tps

for reference, it's the 2nd fastest model tracked in the "Highlights" section of https://artificialanalysis.ai/
