Our Commentary ​

OpenAI continues to iterate quickly. Improving Sol's accuracy is always welcome, but the expanded free access to Luna is the real headline here. It feels like a strategic move to keep users engaged and broaden their reach, especially as competition heats up. I wonder what the "unlimited everyday chats" really means in practice.
