Cursor v0.51 has been out for a few days now, but the official download page still doesn't have the v0.51 download links. Here are the official download links for the latest Cursor version v0.51.12that I found on Github (domain: downloads.cursor.com). Feel free to download and try it out if you want to give it a spin.
Cursor now supports the DeepSeek R1 0528 model, but it's not enabled by default. You need to go to Cursor Settings -> Models, find "deepseek-r1-0528", and check it to enable it.
Cursor error message: We're experiencing high demand for Claude 4 Sonnet right now. Please switch to the 'auto-select' model, another model, or try again in a few moments.
