Claude Opus 5.5 vs MiniMax M3.1 Flash

Only numbers stated in each post. “—” means the post doesn’t say.

• Running elephant animation, 3 modelsOpus 5.5 still has the richest scene, with DeepSeek keeping up and the gap closing fast.— the author’s view, @pipeline_os (paraphrased)
• Paper receipt and fabric under pressure, four modelsMiniMax M3.1 Flash did best: the receipt kept its shape and legible text. DeepSeek got sharp folds in motion, Opus’s paper was too soft, GLM’s too rigid.— the author’s view, @sakatayasha (paraphrased)
• 3D villa construction, three modelsDeepSeek beat MiniMax M3.1 Flash, but the author disagrees that it is close to Claude Opus 5.5 at 3D modeling.— the author’s view, @AI_Screening (paraphrased)
• Three jelly bears under a pressSame end result, but MiniMax stays clear under the press while Opus goes duller, and it costs a fraction: the one to run every day.— the author’s view, @semichenkko (paraphrased)
• Animated rocket race explainer in one HTML fileClaude Opus 5.5 is best by a mile; the cheap models are drafts, and Gemini gives about 80% of Opus for under a third of the price.— the author’s view, @HeyAIpenguin (paraphrased)
• One-file Minecraft game, 4 modelsClaude Opus 5.5 wins this round; the author points to its water at the end.— the author’s view, @davit__yan (paraphrased)
• 3D Hall of Supreme Harmony, three modelsOpus won all three tasks; MiniMax M3.1 Flash and DeepSeek 1017 were about even, and MiniMax ringed the square with trees.— the author’s view, @xiaoyu_agi (paraphrased)
• Whale breach in Three.js, four models one-shotOnly DeepSeek V4.1 Flash made a real ocean and MiniMax M3.1 Flash’s breach held up; GPT-6.1 Sol’s ocean shader didn’t compile and Opus 5.5 crashed on load.— the author’s view, @elliscrosby (paraphrased)
• Sliceable jelly toy, MiniMax vs OpusMiniMax went full agent mode, started rewriting the physics engine and died on an insufficient-balance error with no jelly; Claude just made a jelly you can slice.— the author’s view, @ottollm (paraphrased)
• Rube Goldberg machine, Opus vs Space BunnyOpus built a full 3D workshop with a rocket finale; Space Bunny made a flat 2D board with labels and confetti. It runs, but it is not frontier.— the author’s view, @mkeremturhan (paraphrased)
• 3D lab with rewritable laws of physicsMiniMax has a ways to go; Opus is crazy with physics.— the author’s view, @RezAIT00 (paraphrased)
• Tesla Roadster POV drive, four modelsOpus 5.5 is the quality winner; MiniMax came out worst visually.— the author’s view, @RafaCrackYT (paraphrased)
• Flying Tesla Roadster, MiniMax vs OpusOpus still wins on realism, but MiniMax got most of the way there for less than a coffee.— the author’s view, @narushima_ (paraphrased)

Build a fully interactive 3D laboratory where the user can rewrite the laws of physics in real time. Make heavy objects fall upward, reverse friction, redirect collision momentum sideways, and create fluids that repel one another. The lab must strongly emphasize true 3D spatial simulation with depth-rich environments, volumetric liquids, rotating rigid bodies, layered test chambers, gravity zones, and emergent interactions visible from every angle. Every altered law must remain mathematically consistent across the entire 3D world, turning the experience into a believable sandbox of impossible physics. — @RezAIT00
