我目前是用的CPA反代，codex已经在用户目录里修改了config文件了 
具体修改情况如下： 
approval_policy = "never"
approvals_reviewer = "user"
model = "gpt-5.6"
model_auto_compact_token_limit = 350000
model_context_window = 1050000
model_provider = "cliproxyapi"
model_reasoning_effort = "xhigh"
review_model = "gpt-5.6-terra"
sandbox_mode = "danger-full-access"
plan_mode_reasoning_effort = "xhigh"

但是在重启打开后仍然没有看到新模型，请问有uu指导一下吗 
是否还要修改别的...
