The Sonnet 5.5 on my free account appears to be worse than the one on my paid account? Asked it to one-shot a castle with the same prompt. More below.

>Can you generate an aerial view of a medieval stone castle and the surrounding grounds, early morning light, as a 3d model, in a single html file, allowing zooming and rotating, no words at all, just the scene.  
  
Record the time you started, and finished.  
  
These are the project requirements:  
  
Professional visuals

>Produce finished professional work. Target the quality of an Awwwards-featured website, a commercial CGI campaign, or a published scientific illustration, whichever fits the request.

>Use the strongest appropriate rendering techniques. For realistic offline 3D, default to path tracing and global illumination. For interactive visuals, achieve comparable visual richness within the performance budget.

>Match the subject's real complexity. Include the irregularity, material variation, fine structure, and imperfections visible in its real-world equivalent.

>If the task is a 3D render, pay special attention to the geometry before anything else. Ensure that seams and attachment points look natural. No visual artifacts.

>Make specific artistic choices without waiting for direction. Choose the composition, lighting, camera, palette, and motion needed to make the requested subject compelling.

>Use the reference class that fits the work:

>Web: ready to submit to Awwwards.

>Natural environments: the richness and lighting of a high-end cinematic game environment.

>Objects and organisms: a professional asset shown in a commercial product render or natural-history close-up.

>Shaders and motion: a commissioned motion-design piece for a leading creative studio.

>Offline renders: a finished commercial CGI image, with production-quality geometry, materials, and lighting.

The one on my free account worked for \~5 mins, the paid one \~30 mins.

Thought it was noise, so I tried it 3 more times, and got similar results. Free one took 1-6 mins, paid one 20-35 mins. Similar visual quality as the above vid. After that, I hit limits on the free one, so I didn't go further.  
  
This is on chat, not Claude Code btw. I asked the one on my paid account whether it had access to any of my preferences, skills etc, it said no. I wouldn't trust it fully, but it seems something might be going on.  
  
Can anyone else confirm?
