# MiniMax-M3.1-Flash-Preview — ad-hoc, UNVERIFIED figures

Supplied by the operator on 2026-10-13 with no source URL. Not from Artificial Analysis (the model is not on
that leaderboard yet — see `artificial-analysis/README.md`). Do not use for registry scores until confirmed.

| Item | Figure | Note |
|---|---|---|
| KingBench 3, M3.1 Flash | 66.25% (53/80) | "community and third-party testing"; arithmetic checks (53/80 = 66.25%) |
| KingBench 3, M3 baseline | 31.25% (25/80) | arithmetic checks; the source also mentions "alternative baseline figures depending on the evaluation set" |
| M3 SWE-bench Pro | ~59% | reference baseline for M3, described as official |
| M3 "Browse.com" | 83.5 | benchmark name looks mistyped (BrowseComp?) — confirm before citing |
| M3 Terminal Bench 2.1 | "strong" | no number given |

Caveats: unknown effort level for the KingBench runs (Flash always thinks; server default is max); KingBench 3 is
small (80 items) so one item is 1.25 points; none of these figures share a scale with the AA Intelligence Index
(M3 = 29 there), so they cannot be mixed into one cost-per-intelligence figure.

## TODO(revisit) — placeholder estimate in use (2026-10-13)
`estimates.csv` carries a stop-gap row for M3.1 Flash: cost per task = 90% of M3's ($0.51 -> $0.46) and
intelligence index = M3's AA index (29) scaled by the KingBench-3 ratio (66.25/31.25 = 2.12) = 61.5. That index
would rank it above Claude Opus 5.5 max (58), which is implausible for a Flash-class model — treat both numbers as
rough placeholders. Replace with (a) the Artificial Analysis row when the model is listed, or (b) our own measured
cost per task at each effort level (fixed task set via `ask-minimax-run --output-format json`).
