Woofun AI reports that Goldman Sachs maintained its "Buy" rating on MiniMax Group, setting a target price of HK$860. The bank highlighted that MiniMax's M3 model matches the pricing of M2.7 while doubling inference efficiency through architectural upgrades, effectively offsetting parameter costs. Goldman Sachs noted that DeepSeek's planned mid-July V4 launch and peak-hour pricing increase indirectly validate M3's cost-effectiveness. Upcoming M3 series expansions and the H3 video model are identified as further catalysts.
