Grok API pricing, October 2026: every xAI model per million tokens
Input, cached and output prices for every Grok model, xAI's list price next to ours, and what a chat turn and a long-document request cost on Grok 4.7, 4.5 and 4.3.
How the Grok API is priced
xAI bills Grok API calls per token, at three rates per million tokens: input, cached input and output. Grok output costs two to three times input, a smaller gap than most flagship models. A request costs its tokens times the rates of the model it named; there is no seat or plan price.
Every Grok model
5 Grok models. Each row shows our price and xAI's list price.
| Model | Input | Cached | Output | List input | List cached | List output |

| Grok 4.6 | $0.60 | $0.15 | $1.80 | $2.00 | $0.50 | $6.00 |
| Grok 4.7 | $0.60 | $0.15 | $1.80 | $2.00 | $0.50 | $6.00 |

USD per million tokens. Ours from the live catalog; list is the price on xAI's pricing page, the read date on each model page.
The lowest price here is Grok 4.3: $0.75 in and $1.50 out.
Two requests, worked
A chat turn of 2,000 input and 500 output tokens, and a long-document request of 50,000 input and 2,000 output. Both sizes are assumptions; nothing is counted at the cached rate.
| Model | Chat turn, list | Chat turn, here | Long document, list | Long document, here |
|---|---|---|---|---|
| Grok 4.7 | $0.007 | $0.0021 | $0.112 | $0.0336 |
| Grok 4.5 | $0.007 | $0.0021 | $0.112 | $0.0336 |
| Grok 4.3 | $0.0038 | $0.0023 | $0.0675 | $0.0405 |
Input tokens times the input rate plus output tokens times the output rate, per million.
Grok 4.7: $0.60 in and $1.80 out here, against $2.00 and $6.00 at list, 70% under on input and 70% on output.
Grok 4.5: $0.60 in and $1.80 out here, against $2.00 and $6.00 at list, 70% under on input and 70% on output.
Grok 4.3: $0.75 in and $1.50 out here, against $1.25 and $2.50 at list, 40% under on input and 40% on output.
Cached input
When a request repeats a prefix the API has seen, such as a long system prompt or a document, the response reports those tokens as cached and they bill at the cached rate in the first table. A model with no cached rate bills them at its input rate.
Calling it
Point the SDK at our base URL with your key. Every Grok id in the table works with the same two values.
from openai import OpenAI
client = OpenAI(
base_url="https://api.uplinkswitch.com/v1",
api_key="sk-uplink-live-...",
)
completion = client.chat.completions.create(
model="grok-4.7",
messages=[{"role": "user", "content": "Summarize this in one line."}],
)
print(completion.choices[0].message.content)More in the SDK guide.
Questions
Is there a subscription? No. Credit is prepaid from $10, and each top-up locks your prices for 30 days. New accounts start with $1 free.
Which Grok model should I use? Grok 4.7 for most work; its input and output prices here match 4.5 and 4.6. Grok 4.3 has the lower output price, so it fits long answers where the newest model isn't needed. Run the same prompt on each and compare.
Where is the full price list? On the Grok pricing page, and every other model on the Models page. To see what your own usage would cost, re-price an export on the savings page.
