Best for
- Computer-use and tool-calling agents at half GPT-6.1 Sol's price
- High-volume reasoning work that stays under the 272K long-context threshold
Watch out for
- Prompts over 272,000 input tokens bill the whole request at $2 input and $7.50 output per 1M tokens
- Reads text and images only: audio and video input are not supported
MiMo-V2.6-Flash
Where it leads
- Lower input and output prices, $0.14 and $0.28 vs $1 and $5 per 1M tokens
- Accepts audio and video input
- Open weights you can run yourself
- Cheaper cached input, $0.0028 vs $0.05 per 1M tokens
- Batch pricing, $0.07 input and $0.14 output per 1M tokens
Best for
- High-frequency multimodal calls
- Low-cost agent workloads
Watch out for
- Xiaomi's own table puts it well behind the Pro model on exploitation tasks (ExploitBench 25.3 against 47.9)
- The API checkpoint (RL or MOPD weights) is not identified
