Claude Agent SDK Sub-Agent 自定义模型问题

最近在用 Claude Agent SDK 开发，由于公司安全限制，只能使用百炼模型，因此我设置了

ANTHROPIC_BASE_URL=https://dashscope.aliyuncs.com/apps/anthropic
ANTHROPIC_MODEL=qwen3-max
ANTHROPIC_SMALL_FAST_MODEL=qwen-plus

但是触发 Sub-Agent 时（比如 Explore ），强制使用 qwen3-max 会报错，导致 Sub-Agent 无法使用。大家遇到这个问题了吗？有什么解法吗？
