GPT-6 Astra 图像生成对比：质量与成本优势显著
原标题：The Pelican comparison grid for Astra is pretty interesting
AI 摘要
Simon Willison 在 2026 年 9 月 4 日获得 GPT-6 Astra 的访问权限，并用它生成不同推理级别的自行车鹈鹕 SVG 图像，与 GPT-5.6 Sol、Terra 和 Luna 进行对比。结果显示 Astra 生成的图像质量明显优于其他模型，且成本效率更高，低推理级别下仅需 9.55 美分即可获得比 Sol 任何级别更好的结果。此外，Astra 和 Luna 的输入 token 数相同，暗示两者可能关系更密切。

The Pelican comparison grid for Astra is pretty interesting 4th September 2026 I got access to GPT-6 Astra this afternoon, so naturally I used it to generate SVGs of pelicans riding bicycles—at low, medium, high, xhigh and max reasoning levels (Astra doesn’t support reasoning=none). Then I rendered those pelicans in a comparison grid with GPT-5.6 Sol, Terra, and Luna, and beyond being fun the result was surprisingly useful. See the grid for full quality images.
