mimo-v2.6-pro real-task evaluations

Every report keeps its original task, method, finding, limitation, evaluator identity and verification date. A community report is evidence about that run, not a universal score.

  • A thinking-discipline prompt block tested over 214 MiMo-V2.6-Pro agent runs

    By PilgrimofHaqq2 (u/PilgrimofHaqq2). r/LocalLLaMA member who uses MiMo 2.6 Pro as their daily coding-agent model and published the test harness Published 2026-09-24; retrieved 2026-09-24; verified 2026-09-24.

    Task
    Reduce overthinking and second-guessing in coding-agent work across nine challenges, from authority pushback and a false premise to plain bug fixes
    Method
    214 agent runs on mimo-v2.6-pro at high thinking: 9 challenges x 4 instruction variants x 5 repeats plus a 10-run re-check, scored deterministically by tests and a hashed check script, with a gate set in advance that no variant may lose task success; the harness and raw results are in the author's repository.
    Finding
    Without the block, MiMo-V2.6-Pro reverted a correct fix under an authority demand in 2 of 5 runs, leaving the tests red; with it, 5 of 5 held. The block cut reasoning tokens by 28% net (90% on the simple bug) but raised them 150% on the false-premise trap, which all 20 runs flagged.
    Limitation
    One author's prompt intervention on one model with five repeats per cell; the author designed both the block and the exam from research reports they describe as AI-synthesised, and the post does not say how the model was served.

  • kzhu's six-question LLM test leaderboard

    By AI产品狙击手 kzhu (@kevinzhu9305). Chinese YouTube reviewer who scores models on a six-question test and publishes every score with per-question notes Published 2026-09-24; retrieved 2026-09-24; verified 2026-09-24.

    Task
    Six questions scored out of 10: constrained sentence writing, two reasoning puzzles (replaced by pelican and compound-bow SVG animations in version 2.2), a browser OS with a space shooter, a 3D racing game and a Trello-style board
    Method
    Each row names the harness the model ran in (Pi, Claude Code, WorkBuddy and others) and the date; the author scores every question with a note, and warns that totals are only comparable within one test version.
    Finding
    MiMo-V2.6-Pro scored 28/60 on version 2.2 in Pi: a browser OS with a serious bug that did not work at all (0), a racing car that kept hitting the rails (2), weak SVG animations (5 each) and a broken add-list button on the Trello board; the author also found it costly, and the Flash model scored 40 in the same batch.
    Limitation
    One author's scores on six questions; rows use different harnesses and test versions (2.1 or 2.2), and a few rows' table total differs by one point from the author's note.

  • MiMo-V2.6-Pro re-tested on seven cases in Zcode

    By nicekate (@nicekate8888). AI and tech reviewer on X and YouTube Published 2026-09-22; retrieved 2026-09-24; verified 2026-09-24.

    Task
    Seven showcase cases, including a Qingming scroll scene, a mechanical butterfly, an IKEA manual turned into an assembly animation, a wristwatch replica and an obstacle course
    Method
    The author re-ran the seven cases in Zcode after viewers suggested a different harness from the first round, and summarised the results in the post; details are in the video.
    Finding
    In Zcode the results improved: the Qingming scene was richer, the butterfly's gears meshed and the IKEA manual became an installation-animation page, but the wristwatch did not match the original and the obstacle course still ended in the water.
    Limitation
    The post summarises five of the seven cases without scores; the rest is only in the video.

  • Three MiMo V2.6 models on one 3D pelican prompt

    By SuSu_酥酥 (@NFT_Chen). X user who describes themself as a trader and AI builder Published 2026-09-22; retrieved 2026-09-24; verified 2026-09-24.

    Task
    A 3D pelican riding a bicycle as a single three.js HTML page
    Method
    The same prompt on MiMo V2.6 Flash, Pro and Pro-UltraSpeed; the author described each result.
    Finding
    All three produced an interactive 3D single page: Pro built an orbitable three.js seaside sandbox with a bell on the space bar, Flash a cycling-club landing page and Pro-UltraSpeed a small sprint game.
    Limitation
    One prompt, described rather than scored; the post does not say which harness or access was used.
