Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
Google · Mar 2025
Google's 2025 workhorse flagship — first mainstream thinking model with a 1M context, still widely deployed.
Moonshot AI · Apr 2026
Moonshot's multimodal flagship that ties GPT-5.5 on several coding evaluations at a fraction of the price, with open weights.
The verdict
Kimi K2.6 wins 1 of the 1 benchmarks these models share, against 0 for Gemini 2.5 Pro. Kimi K2.6 is about 2.0x cheaper per blended million tokens (3:1 input:output mix). Gemini 2.5 Pro also takes 1.0M of context versus 262K for Kimi K2.6. And Kimi K2.6 is open-weights (Modified MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
