OpenAI Rolls Out Ultrafast Mode for GPT-6.1 Sol

OpenAI has officially launched "Ultrafast Mode" for its GPT-6.1 Sol model, promising speeds up to 8x faster than previous iterations. The update is rolling out across the API, Codex, and ChatGPT Work, targeting power users and enterprises where latency is a critical bottleneck.

While the speed gains are impressive, the community is already questioning if this optimization comes at the cost of reasoning depth or if it's purely an architectural efficiency win.
