This post introduces a head-to-head comparison of Kimi K2.6 on Cerebras hardware against Google's Gemini 3.5 Flash for AI inference speed. It presents benchmark results for output tokens per second, end-to-end response time, and time-to-first-token for voice agents. The post highlights that Kimi K2.6 on Cerebras achieves 981 tokens/s (5.4x faster than Gemini 3.5 Flash), completes tasks in 5.6 seconds (vs. 17.5 seconds), and achieves 452ms time-to-first-token (vs. 960ms for Gemini 3.5 Flash), making it suitable for real-time voice applications. It attributes Cerebras's performance to storing the entire model on-chip.
