Radar's take For anyone picking a backend model for tools like Cursor, a price hike on an open-weights alternative nudges the calculus slightly toward other options such as Claude, GPT, or Gemini. That said, this is a single pricing update with no other news attached, so it mainly matters to people actively comparing API costs across models rather than to most day-to-day users.
