📌 关键信息

• **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 &#34
• opus-class&#34
• 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.

🧭 为什么值得关注
