"chatgpt-4o-latest“模型相较于gpt-4o有显著提升，希望能够支持
目前在config.py中手动添加“chatgpt-4o-latest”模型配置并不能被正常解析

Start in config.py and inspect how model configurations are parsed, comparing the existing gpt-4o entry with the requested chatgpt-4o-latest model. Done means the model configuration is parsed normally and the application accepts the new model; verify the behavior using the repository's existing checks if available.
