xAI publicly launched Grok 4.5, a new coding-and-agents-focused frontier model emphasizing capability-per-dollar rather than benchmark supremacy. Elon Musk described it as "Opus-class" but faster, more token-efficient, and lower cost, with a 1.5 trillion parameter size, making it 3x larger than Grok 4.3. The model is priced at $2 per 1M input tokens and $6 per 1M output tokens, with discounts for cache hits and a context window expected to return to 1 million tokens soon. Cursor partnered in training Grok 4.5, highlighting it as their most powerful model yet and expanding beyond software engineering. Early ecosystem support includes Grok Build/API, Hermes Agent, Portal, and OpenRouter.
