We're excited to release BananaMind 2 Micro, our smallest model yet. It fits a compact architecture in only 2.9M parameters achieving the highest parameter efficiency on BananaMind Base Bench against comparable models. It achieves comparable performance to GPT S2 5M and GPT S 5M at almost half the size while beating CMA 1M Mini. BananaMind 2 Micro achieved the #1 spot on the Open SLM Leaderboard for the sub 3M category (not added yet but it achieves #1) For the training we used Muon + the XSA Refresh Gate with a 5e-2 lr for Muon and 4e-3 for the 1D weights. Its score on our efficiency measure is 0.326 getting the first place with Syn 2.6M on the second place scoring 0.291 and GPT S 5M at 0.235* Check it out at BananaMind/BananaMind-2-Micro and follow us at: @vovaRL @DedeProGames @Banaxi-Tech
