What specific problem does this solve?

Currently, Roo Code does not support the OpenAI gpt-5-chat-latest model. This limits users who want to leverage the latest conversational AI capabilities for non-reasoning use cases, such as code assistance, content generation, and advanced chat functionalities. Supporting this model will enable users to access improved performance and new features provided by gpt-5-chat-latest, keeping Roo Code competitive and up to date with leading AI technology.
