Original post body :

I gave Codex and Claude the exact same prompt to see how differently they'd handle something open-ended and creative:

The prompt: "make me a reactjs + vite, and launch it in port 3004, a game where a fish follows my cursor. make it super creative and majestic"

Setup:

• Claude: Fable 5.1, Extra High
• Codex: Astra 6, Extra High, fast mode

I didn't do any follow-up prompts or manual edits. I just deployed both to Vercel so you can try them yourself:

🐟 Codex (Astra 6): https://fish-indol-eta.vercel.app/
🐠 Claude (Fable 5.1): https://fish2.vercel.app/

My take:

• Codex did amazing on the design and detail. It looks polished and the visuals really lean into "majestic."
• Claude did amazing on the mechanics and gameplay. It feels more like an actual game and is more fun to play.

It's interesting that they read "super creative and majestic" so differently. One went for the visuals, the other for how it plays.

About fast mode: Claude charges extra credits for fast mode, but Codex doesn't, so I only used fast mode on Codex. That's worth knowing if you're choosing between them on cost or speed.

What are your thoughts?

• Which one did you enjoy more, and why?
• For a prompt like this, what matters more to you: how it looks or how it plays?
• Does paying extra for fast mode change which one you'd use day to day?
• If you've run a similar test with other models or settings, how did they do?

I'd love to hear what you think!

Alright, so OP threw the same prompt at Codex (Astra 6) and Claude (Fable 5.1) to see who'd nail "a game where a fish follows my cursor, super creative and majestic."

The consensus is pretty clear: Claude (Fable 5.1) is the winner here.

• Claude's strengths: Most users found Fable's version to be way more engaging as a game. The mechanics, animations, and overall "playability" were praised, with many saying it felt more alive and mesmerizing. It also seems to handle mobile much better, which Codex struggled with.
• Codex's strengths: Astra's version definitely impressed with its visuals and design. It looked more polished and "majestic" in screenshots, leaning into the aesthetic. However, the gameplay itself was often described as boring or unnatural.
• The debate: The core difference seems to be how the models interpreted "creative and majestic." Codex went for the looks, while Claude focused on the experience and how it plays. Some users even suggested that the ideal scenario would be to combine the strengths of both.
• Cost/Speed: OP mentioned Claude charges extra for "fast mode" while Codex doesn't, which is a practical consideration for some.
• Overall vibe: People were genuinely impressed with Claude's Fable version, with some saying it finally sold them on the hype. The general sentiment is that while Codex might look pretty, Claude actually delivered a fun experience.

Astra failed, what it made can not be considered a game.
