When to choose it
- 想要 GPT-5.6 这一代的能力但预算敏感:$0.2/$1.2 每百万 token,是同代 Sol($5/$30)的约 1/25
- 105 万上下文、能看图、能调用工具,规格上并没有为省钱砍掉这些
Caveats
- 同代三个型号(Luna / Terra / Sol)的差异我们没有实测过,只能告诉你价格与规格的差异,不能替你判断质量差多少

Not yet on any leaderboard we track. That does not mean the model performs poorly — it means we have not taken this snapshot for it yet, and we do not publish a score we have not measured.
