Grok 4.5 is now an official xAI API model for coding, agentic tasks, and knowledge work. The pricing is the headline: $2 per 1M input tokens and $6 per 1M output tokens.
Why developers should care
Coding and agentic workloads can become expensive quickly because they often involve long context, tool calls, retries, and iterative planning. A lower API price point makes Grok 4.5 worth testing for agents, code analysis, internal tools, and workflow automation.
| Input price | $2 / 1M tokens |
| Output price | $6 / 1M tokens |
| Use case | Coding, agentic tasks, knowledge work |
AILinkBase take
Grok 4.5 should enter Best AI Coding Models and Best Low-Cost AI APIs review queues. It should not jump rankings automatically. Real-world tool use, reliability, context behavior, and enterprise governance still matter more than launch pricing alone.
