Estimate · grok-tokenizer-estimate · ≈3.85 chars/token Auto-counts as you type
This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.

Frequently asked.
Grok Code Fast 1 pricing questions, with archive status separated from token math.
Q · 01 What was Grok Code Fast 1's API price? +
This archive page uses
$0.2/M input, $0.02/M cached input, and $1.5/M output. Use it for historical billing and migration math, not fresh production routing.Q · 02 Is Grok Code Fast 1 still available? +
xAI's May 15, 2026 retirement guide lists
grok-code-fast-1 as retired. After retirement, requests route to grok-4.3.Q · 03 What should replace it? +
Use
grok-4.3. xAI's current pricing page lists Grok 4.3 at $1.25/M input, $0.20/M cached input, and $2.50/M output.Q · 04 Does prompt caching apply? +
The archive row includes cached input at
$0.02/M. The effective blend assumes 82% cache hits; set cache to off in the calculator for fresh-input workloads.Q · 05 Why keep an archive page? +
Retired model prices still matter for old invoices, migration plans, benchmarks, and generation-to-generation price history. The page is marked as archive so it does not imply current endpoint availability.
Q · 06 How accurate is the tokenizer estimate? +
The widget uses
4.875 characters per token as a planning estimate. Exact billing can vary with language, hidden reasoning, cached prompt boundaries, and tool usage.
