Dev reverse-engineers the Codex desktop app to run Opus with Codex's native tools, switching models mid-thread

X user almmaasoglu found the Codex desktop app so good they reverse-engineered it to run Opus: subscription logins work for both, Claude and GPT models can be switched within the same thread while keeping context, and all of Codex's native tools remain available. Their take: "It's the age of decompilation and there will be no 'closed source' software anymore after this year."
