Four models compared on the same prompt for code-generated animation
Using one prompt, GPT-6.1 Sol, Astra, Sonnet 5.5 and Opus 5.5 each generated a code-based animation; the author rates Opus as the best value, with Sonnet and Opus clearly ahead on quality.
Same prompt for all 4 tests, 100% code generated animation. GPT 6.1 Sol vs GPT 6 Astra vs Sonnet 5.5 vs Opus 5.5 Despite the huge price difference between the final results, if this was a blind test, we would not even say that Sol and Astra are on the same level as Sonnet and Opus. On price, Sol was much cheaper than all other models, and maybe even better than Astra quality wise. On quality alone, Opus and Sonnet were above (by a lot), including richer details, camera movements, effects, being more fluid and engaging overall. And if we consider Price and Quality, Opus is the overall winner, costing 12$ vs 18$ from Sonnet, finishing in 1h and 16m vs 1h and 36m.
