Grok 4.5 Leads Frontier Models in Speed
Daniel_Farinax · x · 2026-07-15
Grok 4.5 is described as significantly outpacing GPT-5.5 Sol and Claude Fable 5 in speed: - Throughput is around **80–112 TPS**, compared to roughly **55–70 TPS** for the Claude series. - **First token latency is under 1 second**. - For coding and agent tasks, overall end-to-end time is typically **2x faster**. - Processing time is halved, and it consumes fewer tokens. The original post concludes that it is the reigning "speed king" among frontier models.
