This one's worth opening because Grok finally has a coding model that can compete, and it was co-trained with Cursor. The performance claim is honest: it sits between Opus 4.7 and 4.8, no "we're number one" nonsense. But the price is 6x cheaper than Opus and 3x cheaper than GPT-5.5 per token. If you're a heavy Cursor user, your token bill just got a lot friendlier. The API is open too, so SpaceXAI is serious about courting developers.
Same day, OpenAI pushed GPT-5.6 (Sol, Terra, Luna) to all users. Early testers say Sol is less smart than Fable but far more reliable. Anthropic extended Fable 5 subscription access to July 12—the post doesn't explain the repeated delays, so I'd put a question mark on that. Meta dropped Muse Image and Video; image editing and text rendering look solid, but images still have that AI sheen, and the video model is preview-only.
Read together, today's news signals that the price war for coding models is on. Grok 4.5's pricing puts direct pressure on Anthropic and OpenAI. The question now is whether Opus and GPT-5.5 will match it.
