SpaceXAI and Cursor Release Grok 4.5 with Opus-Class Performance
What happened
SpaceXAI, in partnership with Cursor, has launched Grok 4.5, a new large language model positioned as an 'Opus-class' frontier model specifically for coding and agent workflows. This release emphasizes capability-per-dollar, touting significantly lower pricing and high performance comparable to leading models like Claude Opus 4.8 and GPT 5.5.
Why it matters
AI Engineers and ML Directors should consider integrating Grok 4.5 into coding and agent development workflows due to its competitive performance, 80 tokens/second speed, and significantly lower pricing of $2/$6 per million tokens compared to rivals.
