Grok 4.5 (launched July 8, 2026) costs $2 per million input tokens and $6 per million output tokens on the API, with cached input discounted about 85%. Consumers get it through SuperGrok, which runs $10 to $300/mo. The sticker price sits mid-pack, but because 4.5 finishes agentic tasks in roughly a quarter of the tokens of rival flagships, the effective cost per completed task is unusually low. Here's every plan.

API pricing

The API is where Grok 4.5 shines for builders. Input is $2/M, output is $6/M, and cached input drops to roughly $0.30-$0.50/M — an ~85% cache discount that adds up fast in repeated agent runs. The context window is 500K tokens. There's no published batch discount for 4.5 yet, unlike the 20% offered on the older Grok 4.3.

The real advantage is hidden in the token count. xAI reports 4.5 resolving engineering tasks in about 15,954 output tokens versus 67,020 for a max-effort Opus 4.8 run — roughly 4.2× fewer. Multiply the lower output rate by far fewer tokens and Grok 4.5 often finishes a task for a fraction of what a pricier-per-token model costs. Developers can also draw up to $175/mo in free API credits via xAI's data-sharing program.

SuperGrok & X plans

For non-developers, access runs through subscriptions. SuperGrok Lite ($10/mo), launched March 2026, is the entry paid tier with Grok Imagine and one AI agent. SuperGrok ($30/mo, or $300/year for ~17% off) is the cheapest standalone path to full Grok. SuperGrok Heavy ($300/mo) adds the multi-agent Heavy tier.

If you already live on X, X Premium ($8/mo) and X Premium+ ($40/mo) bundle Grok with platform perks. Premium+ is the better value there, layering fuller Grok access on top of the X benefits.

Which plan gets Grok 4.5

Rollout was staged. SuperGrok Heavy was the only consumer plan with confirmed full Grok 4.5 access at launch, while standard SuperGrok and X Premium+ received it in phases through July 2026. If you specifically need 4.5 immediately, the API is the surest route, since it exposed the model directly on day one.

Is it worth it?

For developers, yes — clearly. Between the low output rate, the 85% cache discount, the ~4× token efficiency, and up to $175/mo in free credits, Grok 4.5 is one of the cheapest ways to run serious agentic and coding workloads in 2026. If your app makes lots of tool-driven calls, it can meaningfully cut your bill versus higher-per-token rivals.

For consumers, it depends on use. SuperGrok Lite ($10) is a fine casual entry; SuperGrok ($30, or $300/yr) is the standalone sweet spot for heavy users; Heavy ($300) is niche, for people who want the multi-agent tier.

Frequently Asked Questions

How much does the Grok 4.5 API cost?

Grok 4.5 costs $2 per million input tokens and $6 per million output tokens, with cached input discounted to roughly $0.30-$0.50 per million (an ~85% cache saving). It has a 500K context and no published batch discount.

What are the SuperGrok plans?

SuperGrok Lite is $10/mo, SuperGrok is $30/mo (or $300/year), and SuperGrok Heavy is $300/mo. X Premium at $8 and X Premium+ at $40 also bundle Grok access alongside X platform perks.

Which plan gets full Grok 4.5?

SuperGrok Heavy was the first consumer plan with confirmed full Grok 4.5 access. Standard SuperGrok and X Premium+ received it in stages after the July 8, 2026 launch, and the API has it directly.

Is there a free way to use Grok 4.5?

Developers can draw up to $175/mo in free API credits through xAI's data-sharing program. Casual users get limited Grok access via the standard X app, with heavier use gated behind the paid tiers.

Is Grok 4.5 cheaper than GPT-5.6?

Yes, substantially. GPT-5.6 Sol runs $5/M input and $30/M output, versus Grok 4.5's $2/$6. Combined with Grok's token efficiency, the cost gap per completed task is large in Grok's favor.

Does annual billing save money?

On SuperGrok, yes — $300/year works out to about 17% off the $30/mo rate. The other tiers are billed monthly, and API usage is pay-as-you-go with the cache discount doing most of the saving.
