Kimi K2 Base supports a 131K token context window, while MiMo-V2-Omni supports 262K tokens. MiMo-V2-Omni offers a larger context window. Filling a larger window bills more input tokens, so the cheaper-per-million model can still cost more on long documents.
Shared benchmark scores for Kimi K2 Base and MiMo-V2-Omni are still limited. Check the comparison table for the evals each model has published. Check the comparison table for GPQA Diamond, SWE-bench, MMLU, HLE, and the other evals we track. Token price and benchmark score together are the usual LLM comparison, not either number alone.
Both Kimi K2 Base and MiMo-V2-Omni are production API models. For cost-sensitive production traffic, MiMo-V2-Omni has better economics on the blended 1M-in + 1M-out scale. For maximum capability, weight the benchmark table for your domain.

List rates are the latest published OpenRouter API pricing and OpenRouter API pricing, quoted per million tokens. Official rate sheets: https://openrouter.ai/moonshotai/kimi-k2 and https://openrouter.ai/xiaomi/mimo-v2.5. Prompt caching, batch APIs, and committed-use discounts can change the invoice.
