SpaceXAI (formerly xAI) puts Grok 4.3 on its API, a 1M-token reasoning model at $1.25 per 1 million input tokens and $2.50 per 1 million output tokens, about 40% and 60% cheaper than Grok 4.20; Artificial Analysis scored it 53 at launch.

SpaceXAI releases Grok 4.5, its first model trained jointly with Cursor, for coding, agentic and knowledge work at $2 per 1 million input tokens and $6 per 1 million output tokens; Artificial Analysis ranks it fourth with 54 on its Intelligence Index.

SpaceXAI, formerly xAI, releases Grok 4.7, its most capable model for coding and knowledge work, built on a larger base model and priced like Grok 4.6 at $2 per million input tokens; independent tests still put it well behind Claude Fable 5.1 and GPT-6.

Tesla demonstrated its next-generation Roadster at SpaceX’s McGregor facility on October 15, showing suction-assisted ramp driving and cold-gas-thruster stunts. Consumer production is targeted for 2028; a current production price and public-road approval for the Rocket feature remain unestablished.

Polymarket traders price a 39.5% chance that xAI will release Grok 5 by December 31, 2026, following the release of Grok 4.7 in September.
