I GAVE MINIMAX M3.1 FLASH A REPO WITH TWO HIDDEN BUGS AND ONE PROMPT, IT FIXED BOTH IN 27 SECONDS FOR LESS THAN A CENT Space Bunny, the stealth model that sat at #1 on OpenRouter for 10 days, was M3.1 Flash all along -> now it has a name, a price and a terminal. My test: a FIFO PnL tracker with 2 of 6 tests red and no hints about where the bugs are. • What it did on its own > Ran the tests, read the code, found that sells were matching the newest lot instead of the oldest and the buy fee was added to PnL instead of subtracted. > Edited http://pnl.py twice, reran pytest, then ran the CLI on the sample CSV to double check. Tests untouched, 6 passed. • What the run cost > 19.3K input tokens, 2.1K output, 116K served from cache. > At $0.15 in / $0.60 out per 1M that is about $0.006 for a fixed bug, benchmarked at 73.7% on DeepSWE next to Opus 5 at 74.0. Unlimited M3.1 Flash in MiniMax Code until Oct 25 and M Plan 50% off the first month through Oct 31 -> paste one failing test into @MiniMax_AI's terminal and watch what a cent buys you now.
