原标题：Claude Opus 5.5, GPT-6 Sol, GPT-6 Luna, and a new price war
AI 摘要
Anthropic 发布 Claude Opus 5.5，约一小时后 OpenAI 发布 GPT-6 Sol 和 GPT-6 Luna。GPT-6 Sol 和 Luna 价格仅为 GPT-5.6 同级模型的一半，GPT-6 Luna 输入/输出定价低至 $0.10/$0.50 每百万 token；Claude Opus 5.5 相比 Opus 5.0 降价 20% 至 $4/$20。作者实测发现 Claude Opus 5.5 在 max 思考级别下因输出 token 超限而无法完成简单 SVG 任务，并认为当前价格战主要影响中端模型层级。
