The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Xiaomi's[5] MiMo-V2.5 post is dated "April 22nd, 2026" and begins "Today, we are releasing MiMo-V2.5"; Decrypt's[6] 22 April article reports the launch of both models that day. The Pro post of 27 April is the open-sourcing of the weights.
The model card: MIT licence, 70 layers (10 global-attention and 60 sliding-window), 384 routed experts with 8 active, three MTP modules, 27T training tokens in FP8 mixed precision, SWE-bench Pro 57.2, SWE-bench Verified 78.9 and Terminal-Bench 2.0 68.4, and the benchmark.jpg comparison table.[1]
Independent evaluation: 26 on the Intelligence Index v4.3.2 (23rd of 117), about 30 output tokens per second, $0.435 per 1 million input and $0.87 output, $0.05 per Intelligence Index task, a 1M-token context.[1]
Xiaomi's[1][5] API model page for V2.5: 1M-token context, 128K max output, CNY 1 / CNY 2 and $0.14 / $0.28 per 1 million input and output tokens, and a banner that V2.5-Pro and V2.5 requests auto-route to V2.6 on 14 Oct 2026 with the old IDs invalid from 21 Oct.
Xiaomi's[1] Pro post (dated 27 April): 1.02T parameters and 42B active, hybrid attention and 1M context, a SysY compiler in Rust finished in 4.3 hours and 672 tool calls at 233 of 233 tests, a video editor of 8,192 lines over 1,868 tool calls, ClawEval at 64% Pass^3 with about 70K tokens per trajectory, and the open-sourcing of the weights, Base models included.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
