Grok Build 0.1

Current

$2.70 a month

$0.0018 for one request, and $0.09 a day at 50 requests a day.

Show the maths
  • New input: 1,000 tokens × $1.00 per million = $0.001
  • Output: 400 tokens × $2.00 per million = $0.0008
  • 1,500 requests a month × $0.0018 = $2.70

  • Caching half the input would save about $0.60 a month

    That uses the published cache-read price of $0.20 per million tokens. It assumes half of these input tokens are already in a cache. Writing the cache can cost extra, and that write price is not included.

  • A reply half as long would save about $0.60 a month

    Output tokens are often the expensive part. Asking for a shorter answer cuts that cost directly.
