Inkling Small (by Thinkingmachines) and MiMo-V2.5 (by Xiaomi) are compared below. Here is how they stack up on benchmarks, price, and capabilities, and which one to pick in 2026.
There are not enough shared, protocol-compatible benchmark results to declare a performance leader.
MiMo-V2.5 is about 3.6× cheaper on a blended 3:1 input/output basis ($0.18 vs $0.64 per 1M tokens).
MiMo-V2.5 has the larger context window (1,050,000 tokens vs 524,288 tokens).
Choose Inkling Small if…
- • your own prompt tests favor its output; shared comparable evidence does not identify a unique advantage
Choose MiMo-V2.5 if…
- • lower blended API cost matters for your workload
- • you work with longer documents, transcripts, or codebases
The benchmark count includes only results measured with a matching benchmark version and protocol. Arena scores are shown separately. Missing, preliminary, and incompatible data is not treated as a controlled win. Published point-score comparisons are labeled separately when protocol details are incomplete. For text-output models, the verdict also compares token pricing and context windows.
