Its very difficult to work with SVGs with Fable and Opus, Astra is way ahead.

A developer found it challenging to work with SVGs using Fable and Opus for a procedurally animated agent avatar project. They spent significant time trying to generate SVGs with Fable 5.1 and Opus, but the results were unsatisfactory. Ultimately, they used GPT-2.5 to conceptualize the mascot and Astra to generate the SVG, which produced a more polished outcome, suggesting Astra's superiority in this specific task.

This developer's direct comparison highlights Astra's superior SVG generation for animated avatars compared to Fable 5.1 and Opus, which produced much worse results.
