VulcanBench(@VulcanBench):I wanted to share a bit more about the benchmark results of our first voice model comparison with VulcanBench. We asked Grok Voice Think Fast 2.0 and GPT Realtime the same 200 questions, typed vs spoken. Here's the results: Grok: 99.0% text → 95.7% audio (+3.3 pp) GPT Realtime: 97.5% → 93.5% (+4.0 pp) Real, but small. And here's a little thread for anyone that wants to dive deeper into the details. A voice model benchmarking thread 🧵
