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.
