请问各位大佬，我已经升级到最新的sub2api，看官方说已经支持了fast模式，并且我已经开成透传 
 [image] 
codex的config.toml已经配置了 
[features] 
service_tier = “fast” 
plan_tool = true 
view_image_tool = true 
streamable_shell = false 
rmcp_client = true 
skills = true 
parallel = true 
unified_exec = true 
shell_snapshot = true 
steer = true 
multi_agent = true 
prevent_idle_sleep 
为什么codex还是显示不了fast
