Benchmark data for GPT-5 (high) and MiMo-V2.5-Pro is coming soon on BenchLM.
Confidence note. This is a partial-evidence comparison with 16 shared benchmark results across 6 evidence categories; 0 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
BenchLM has partial data for these models, but not enough overlapping benchmark coverage to produce a fair score-level comparison yet.
MiMo-V2.5-Pro has the larger context window at 1M, compared with 128K for GPT-5 (high).

Frequently Asked Questions (3)
Can I compare GPT-5 (high) and MiMo-V2.5-Pro on BenchLM yet?
Not fully yet. BenchLM is tracking both models, but the sourced benchmark breakdown for this comparison is still coming soon.
Why does this comparison show “coming soon”?
BenchLM only shows category winners and benchmark-level calls when we have sourced results that can be compared fairly. For these models, the public benchmark coverage is not complete enough yet.
What data is available for GPT-5 (high) and MiMo-V2.5-Pro today?
GPT-5 (high): $1.25 input / $10.00 output per 1M tokens MiMo-V2.5-Pro: Pricing unavailable Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
