Ifanr tested the newly launched MiniMax M3.1 Flash Preview against Claude Opus 5.5 by reusing public prompts from well-known Opus front-end cases in MiniMax Code. Across a 15-second motion design portfolio, a hand-drawn short film, an ink-style animation, an interactive New York skyline timeline, and game prototypes, M3.1 Flash showed front-end creation ability comparable to Opus 5.5, with the author preferring its visual consistency in some tasks. The piece argues that as Flash-tier models blur the split between flagship and budget tiers, speed and cost advantages matter more for agent workflows with dozens of model calls.
