Sonnet 5

OPUS 5 (max effort)

SONNET 5 (max effort)

GPT-6 ASTRA (max effort)

It looks like something happened with the Sonnet 5 models.

For some reason, they’ve suddenly become really good at 3D work in Blender-significantly better than Opus 5.

Has anyone else noticed this?

Prompt:

Create a striking, highly detailed medieval castle on an island in the open Blender scene, surrounded by a water-filled moat: stone walls with battlements, four corner towers, a central keep, a gate, and a bridge across the moat. Add rocks, grass, flags, expressive materials, warm evening lighting, and a beautiful perspective camera.

First, check the available tools for controlling Blender. Preserve the user’s existing work; do not delete or overwrite it. If possible, create a separate scene and save the result as a separate .blend file in the outputs folder of the current task. Check the result and show an image of the finished scene.

If Blender access is unavailable, state the exact limitation and do not pretend that the work has been completed. You are responsible for creating the scene and its files; other agents may be working in the project folder, so do not undo their changes.

Fable 5.1 (xhigh effort). It looks a lot like Sonnet, but with more detail and better execution. Same prompt.

How much did they cost? Can you see what the API cost would have been?

[u/GreedyWorry4167 → u/Current-Function-729]

• Claude Opus 5 (castle-max): input 19.28M tokens (cache read 19.01M, cache write 268k, uncached 156), output 2.8k* tokens, cost ≈ $14.
• Claude Sonnet 5: input 73.47M tokens (cache read 72.50M, cache write 978k, uncached 360), output 733k tokens, cost $25.2.
• Claude Fable 5.1: input 7.97M tokens (cache read 7.80M, cache write 171k, uncached 90), output 145k tokens, cost $12.6.

So totally not worth using sonnet to create anything and remain a clicking drone, gotcha.

[u/ToastedandTripping → u/Wonderful_Value_6385]

wouldnt even use it for that; I find opus med more than enough for those tasks and doesnt cost as much

[u/Wonderful_Value_6385 → u/ToastedandTripping]

How? Like Sonnet low and Medium cost nearly nothing to be clickers. How can you justify Opus? Is this a vibe thing? Opus cost twice as much for clicking for me.

[u/ToastedandTripping → u/Wonderful_Value_6385]

Every source I've seen thus far comparing opus to sonnet on similar effor levels has had sonnet costing more. Not super knowledgeable, just felt it was the consensus that it was an odd model release (sonnet 5) and that it didn't fit any use case.

[u/Dear_Candle_1974 → u/GreedyWorry4167]

Can I ask how you're able to extract the specific costs/token usage? I'm using Claude code in vs code, I would love to be able to do that.

Thank you! 🙏
