Grok API Pricing (November 2026)
Grok API prices run from $1 to $6 per million tokens across 8 current models. The cheapest is Grok Build 0.1 at $1.00 input and $2.00 output per million tokens. The flagship, Grok 4.7, costs $2.00 input and $6.00 output per million tokens. Every rate below was read on SpaceXSI's own pricing page, on the date shown in its row.

US dollars per million tokens, list rates on SpaceXSI's own API. Cache read is the price of a cached input token. Batch is the asynchronous API, where the vendor offers one. The date in each row is when we last read it on the vendor's pricing page; it links to that page.
Grok API monthly cost estimates
What light use (10M input + 2M output tokens a month), medium use (100M input + 20M output tokens a month), heavy use (1B input + 200M output tokens a month) costs on each current model, at list price with no caching and no batch discount.
| Model | Input / output per 1M | Light · 10M + 2M | Medium · 100M + 20M | Heavy · 1B + 200M |
|---|---|---|---|---|
| Grok Build 0.1* | $1.00 / $2.00 | $14.00 | $140 | $1,400 |
| Grok 4.3, 4.20 (0309) Reasoning, 4.20 (0309) Non-Reasoning, 4.20 Multi-Agent (0309)* | $1.25 / $2.50 | $17.50 | $175 | $1,750 |
| Grok 4.7, 4.6, 4.5* | $2.00 / $6.00 | $32.00 | $320 | $3,200 |
* Assumes every prompt stays under 200K tokens; above that the model bills its higher long-prompt rates. Prompt caching and the Batch API cut these figures; the next sections show by how much. For your own token counts, use the LLM API cost calculator.

console.x.ai + docs.x.ai — the direct API, OpenAI-compatible Chat Completions plus a Responses API. A US regional endpoint, us.api.x.ai, keeps inference in the United States at 1.1x the rates for Grok 4.7 and 4.6. SpaceXSI's docs also list OpenRouter, Vercel and Cloudflare as gateways serving Grok 4.7.
grok.com for standalone chat, X (Twitter) for in-feed integration. Since October 2026 sold as The X Subscription, one plan for Grok, Cursor and X: Plus at $8/mo, Premium at $30, Super at $100, Ultra at $200, above a Free tier. SuperGrok is no longer sold to new customers; existing plans continue.
AGENT · HOSTEDSpaceXSI's work agent — persistent bots on a hosted cloud computer, not a coding tool. Sold with no price of its own: included from Premium up on The X Subscription, on the one weekly pool it shares with Cursor and the Grok apps.
AGENT · TERMINALSpaceXSI's coding agent — the one the name Grok Bot is mistaken for. Runs locally in a project directory, harness and TUI open source under Apache-2.0, and included on every tier of The X Subscription including the free one. Its allowance is not its own: one weekly pool covers Chat, Imagine, Voice, Grok Bot, Cursor and Build together, and the API is billed outside it.
CLOUD · RESELLERSSpaceXSI announced Grok 4.6 on Amazon Bedrock (Aug 19, 2026), Gemini Enterprise Agent Platform (Aug 21), Microsoft Foundry (Aug 26) and GitHub Copilot (Aug 14); the docs add OpenRouter, Vercel and Cloudflare as gateways for Grok 4.7. Each platform bills at its own rates, which are not the vendor rates on this page.
INFRA · COMPUTESpaceXSI's own supercluster in Memphis, TN. Built in 122 days, then doubled in 92 more to 200,000 H100s in a single interconnected cluster, drawing 150 MW at peak, with a stated roadmap to 1M GPUs. Training and inference capacity, not a customer-facing endpoint.
OpenAI
Bigger surface area (image / audio / video / embeddings under one roof), bigger consumer brand. GPT-6 Astra, OpenAI's top model, lists at $10.00 input per 1M against Grok 4.7's $2.00. SpaceXSI wins on per-token cost; OpenAI wins on multimodality and ecosystem.
CODING LEADERAnthropic
The coding-agent incumbent. Claude Opus 5 lists at $5.00 input and $25.00 output per 1M against Grok 4.7's $2.00 and $6.00, and Anthropic publishes a Responsible Scaling Policy. On per-token price alone, Grok is the cheaper bet.
CLOUD GIANTAudio and video in, which Grok has nowhere. Gemini 3.8 Flash takes text, images, audio and video, keeps a 1M window, and at $0.75/$3.75 per 1M it undercuts Grok 4.7 — price is not SpaceXSI's edge at this tier. Distribution through Workspace and Vertex is the other gap.
Meta
Muse Glimmer is the self-hostable one — 30B parameters, Apache 2.0, and Meta says it runs on a single GPU. Its frontier Muse Spark line is API-only, so the trade is the mirror of SpaceXSI's: Meta gives you weights at the small end, SpaceXSI gives you none (Grok 1 was released in 2024, nothing since).
Alibaba (Qwen)
The Qwen (Tongyi Qianwen) model family from Alibaba Cloud's Tongyi Lab. First released in 2023, Qwen is the most-downloaded open-weight model family in the world — most tiers ship under Apache 2.0 on Hugging Face and ModelScope, while the proprietary Max tier is served through Alibaba Cloud's Model Studio.
GLM ARCHITECTZhipu (Z.ai / GLM)
The Beijing lab behind the GLM models, also operating internationally as Z.ai. Spun out of Tsinghua University in 2019, Zhipu ships strong coding/agentic models, multiple free tiers, and open weights — and was the first of China's "Six Tigers" to pursue an IPO. It also sits on the US Entity List.
Grok API pricing FAQ
Practical questions about SpaceXSI, the Grok lineup, the SpaceX merger, and how text-only frontier pricing actually shakes out.
Q · 01 Which Grok model should I start with?
+
Q · 02 Does Grok support vision, audio, or image generation?
+
Q · 03 Did SpaceX really acquire xAI?
+
Feb 2, 2026 at a $250B xAI valuation ($1.25T combined entity). The deal was framed as funding for orbital data centres and giving xAI more capital runway against OpenAI / Anthropic infrastructure spend. The lab has since been renamed twice, to SpaceXAI in July 2026 and to SpaceXSI (SpaceX Super Intelligence) in October 2026, while the console at console.x.ai, the API docs at docs.x.ai and the Grok product line carry on unchanged. Q · 04 Does SpaceXSI offer EU data residency?
+
us-east-1, us-west-2, us-central-1), and the one regional option on the pricing page is a US endpoint. Grok 4.5 did become available in the API console for EU users in July 2026, but that is availability, not EU processing. Since August 2026 Grok 4.6 is also sold through Amazon Bedrock, Microsoft Foundry and the Gemini Enterprise Agent Platform; whether any of them offers Grok in an EU region is that platform's answer to give, and we have not verified it. If EU data residency is a hard requirement, pick Claude on Bedrock EU, Gemini on Vertex EU, or Mistral. Q · 05 What happened in the May 15, 2026 retirement wave?
+
grok-4.3 and bill at Grok 4.3 pricing ($1.25/$2.50). That left four active text models at the time; Grok Build 0.1, Grok 4.5, Grok 4.6 and Grok 4.7 have been added since. Migration guide: docs.x.ai/developers/migration/may-15-retirement. Q · 06 Can I get a discount?
+
Q · 07 How does Grok compare to Claude and GPT?
+
SpaceXSI was founded by Elon Musk on March 9, 2023 as X.AI Corp, with 11 founding researchers (including ex-DeepMind's Igor Babuschkin). The pitch: build a maximally truth-seeking AI inside Musk's ecosystem — X (Twitter) for data and distribution, Tesla / SpaceX for compute and capital. CEO: Elon Musk.
The lab moved fast. Grok 1 shipped November 2023 (weights later open-sourced). Grok 2 in August 2024 added image generation. Grok 3 in February 2025 introduced the reflection / reasoning mode that anchors the current line. Grok 4 in July 2025 was the first frontier-tier Grok ($3/$15) and shipped alongside SuperGrok Heavy, a $300/mo consumer tier that exposed early access to the largest variants. Grok 4.3 on May 12, 2026 cut input prices ~40% to $1.25/$2.50 and the next-generation Grok 4.20 family arrived in 03-09 snapshot form.
The defining infrastructure asset is the Memphis Colossus supercluster, brought online in December 2024 after a remarkable 122-day build. Peak draw 150 MW; expansion plans target 1M+ GPUs.
The corporate structure changed dramatically in 2026. On Feb 2, 2026, SpaceX acquired xAI at a $250B xAI valuation and $1.25T combined-entity valuation — the largest tech merger by valuation on record. Stated rationale: orbital data centres + more capital runway for AI buildout against OpenAI and Anthropic. The lab kept its own API surface and was renamed twice after the deal: SpaceXAI in July 2026, then SpaceXSI (SpaceX Super Intelligence) in October 2026.
Compared to Anthropic and OpenAI: cheaper per token at the frontier (Grok 4.7 at $2.00/$6.00 per 1M against Claude Opus 5 at $5.00/$25.00), a narrower surface (the Grok text models take text and image input and return text, while image generation, video and voice live in the separate Imagine and Voice APIs), and tied to the X / Twitter brand for better and worse.
