MiMo V2.6 Pro RL — Hardware Requirements & GPU Compatibility

ChatFunctions

MiMo V2.6 Pro RL is Xiaomi's largest open-weight language model, a sparse mixture-of-experts design with roughly 1.02 trillion total parameters and about 42 billion active per token. It is tuned for chat and function-calling, with heavy reinforcement-learning post-training behind its name. Only the active parameters compute per token, keeping decoding efficient, but the full weight set must fit in memory, putting it in server-class territory best reached through a hosted endpoint. The model supports a 1,048,576 token context window, suited to very long documents or agent sessions. It is released under the MIT license, one of the most permissive open licenses, with no restrictions on commercial use. Published in September 2026, its post-training relied on large-scale, fully asynchronous reinforcement learning (GRPO).

Frequently Asked Questions

How much VRAM does MiMo V2.6 Pro RL need?

MiMo V2.6 Pro RL requires 612.5 GB of VRAM at Q4_K_M, or 2040.5 GB at BF16. Full 1049K context adds up to 112.5 GB (725.0 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 1020B × 4.8 bits ÷ 8 = 612 GB

KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead ≈ 113 GB (at full 1049K context)
