Cheap Grok API access

Grok model prices

Workload: a chatbot with 10,000 requests a month (1,500 input + 500 output tokens each). Effective prices use the minimum 2× credit; top-ups of $50, $100 and $200 get 2.2×, 2.35× and 2.5×.

How to cut Grok API cost further

• Start with Grok 4.7 and only move up when quality demands it.
• Keep system prompts short and reuse them so cached input is billed at the lower cache rate.
• Cap output length with max_tokens; output tokens cost several times more than input.
• Top up $200 at once for the 2.5× tier instead of many small top-ups.
