Opus 4.6 vs. Minimax M2.5 Prompt: Build an interactive solar system from scratch. Opus 4.6 tried to create a beautiful UI, but the sun’s shadow ruined it. Minimax M2.5 built a simple version that works beautifully. The winner is: 🥇 Minimax M2.5 🥈 Opus 4.6

Claude models are too expensive. Hope Chinese models destroy claude.

this is what i want. chinese open source models are on par with anthropic's models while being 10-20x cheaper

Try Minimax M2.5 on Okara

like it or not, opus 4.6 is better, only small issue is the square yellow of the sun, otherwise? 100% better than Minimax M2.5

A sun with a shadow is the ultimate metaphor for modern AI. We are training models to be poets and artists before they even understand basic physics. Reliability will always beat a pretty UI that does not actually work.

do you use opencode/claudecode/pi ?

depends on the mood tbh. i use opencode, cursor and claude code

Chinese open source just lapped Anthropic on real coding tasks while costing 1/10th. Price & physics > pretty shadows. M2.5 gang rising.

What are your thoughts on SWE-rebench though?

Bravo 👏

Real opinion from someone who's been using agents for over a year: M2.5 is one beast of a model, their coding plan is very affordable. I'm sure Opus 4.6 is still better in general, but look how far open-source has come. Google was right.

pretty amazing

Customers always ask when we present open models: “Are they as good as ChatGPT?” The honest answer: it depends on the benchmark. The real question is different — Do you want to rent Einstein every month… or run von Neumann on hardware you already own?

Guys remember, opus 4.6 is about $15 per million output tokens. Minimax is $1 per hour. That means if you output 20 million tokens in an hour, you only spend $1/20 million tokens. You can’t beat that for a SOTA model. Literally, it’s impossible.

Real life projects are different tho

Hot take most teams do not need more tools. They need harder standards and cleaner execution.

This is amazing!

Opus 4.6 is an Architect; M2.5 is a Senior Dev. This is exactly why MiniMax M2.5 is dominating the 2026 dev stack. It prioritizes the Executable Logic over the 'Visual Vibes.' Opus tried to give you a masterpiece and failed; M2.5 gave you a tool and won. We see this on Canvas.cheetahai co daily: the 'Premium Intelligence' tax for Opus often just buys you more complex bugs. M2.5 is proof that 'Intelligence too cheap to meter' is finally here.

Opus mogged here let's not lie

Happy new year!

minimax at $1/hr is wild. been using it for bulk coding tasks and it honestly handles 90% of what opus does for like 1/15th the cost. the value gap is closing fast

Nice comparison-functionality wins here. Did you run both in the same environment and browser, or were there any setup differences that might’ve affected the shadow/rendering?

I just asked it in claude and my version of the solar system is awesome. I asked Minimax about who made it and it said this … I am Claude, an AI assistant made by Anthropic, a U.S.-based AI safety company.

did you just cherry pick it?

Open weight models are going head to head with Opus? This month has been insane.

Do the US hogging the best chips didn’t slow development of the smartest and cheapest models?

Opus 4.6
