SpaceXAI's smartest model built for coding, agentic tasks, and knowledge work.
Overview
Introducing Grok 4.5
SpaceXAI's smartest model built to excel at coding, agentic tasks, and knowledge work. It's our strongest model ever and was trained alongside Cursor.
Highlights
- Pricing - Grok 4.5 is delivered at an incredibly competitive cost compared to other leading models. Grok 4.5 is priced at $2 per million input tokens and $6 per million output tokens. The model also achieves roughly 2x the token efficiency of comparable leading models, solving tasks in under half the number of steps. Overall, Grok 4.5 delivers the highest intelligence per unit of time and cost.
- Excels at office work- Grok 4.5 now the default model in Grok Build. In addition to its coding proficiency, Grok Build is capable of building complex Excel models that involve research from the web, multi-sheet formula use, and even leaves stickies or notes behind for future reference.In PowerPoint and Word, Grok 4.5 is similarly meticulous. The model is capable of using native PowerPoint shapes to build complex diagrams, designing intuitive slide content, and writing clear prose in Word.
- Real-world engineering excellence: Grok 4.5 was trained on datasets spanning knowledge in coding, science, engineering, and math. With both intelligent and efficient reasoning, Grok 4.5 excels at real engineering tasks and exceeds comparable leading models at these tasks.

Features and programs
Financing for AWS Marketplace purchases
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
Pricing
Pricing is based on the duration and terms of your contract with the vendor, and additional usage. You pay upfront or in installments according to your contract terms with the vendor. This entitles you to a specified quantity of use for the contract duration. Usage-based pricing is in effect for overages or additional usage not covered in the contract. These charges are applied on top of the contract price. If you choose not to renew or replace your contract before the contract end date, access to your entitlements will expire.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.

Dimensions summary
This listing bills through a single contract dimension for Grok 4.5, measured in units. When you purchase, you receive credits applied to your Team ID after account creation. You then draw down those credits as you use the model. Usage is metered by tokens, split between input tokens and output tokens. Optional server-side tools, such as web search, code execution, and file search, add per-call or token-based charges. Storage, downloads, and priority processing also draw from usage. So your cost scales with how much you process and which features you enable, not a fixed per-seat fee.
Top-of-mind questions for buyers
Input tokens cover your query and conversation history. Output tokens cover the model's response. Both are metered per million tokens and billed separately. Output tokens carry a higher rate than input tokens, so response length often drives cost more than prompt length for long generations.
Yes. Once a request's prompt reaches the model's long-context threshold of 200,000 tokens, the long-context rate applies to all tokens in that request, not just the tokens above the threshold. Shorter requests stay on standard rates.
Yes. Priority Processing bills text requests at twice the standard token rate, but only when the response confirms priority service; otherwise standard rates apply. File and collection storage bills per GiB per day, and downloads bill per GiB transferred. These draw from the same usage credits.
