What happened
Grok 4.5 launched at $2 per million input tokens. Tokens are the small chunks of text an AI reads and writes. Output text costs $6 per million tokens. Reused text, called cached input, costs just $0.50. Those prices sit well below many rival frontier models.
The context
Price is one of xAI's strongest cards. Cheaper access can win over developers who watch costs closely.
