Grok 4.6 cost & VRAM calculator
What does Grok 4.6 cost to run for your workload, and can you run it on your own hardware? Set your workload below - we compute per-provider API cost live and tell you honestly whether local hardware can run it.
This is where owning stops making sense
Grok 4.6 is a large-billion-parameter model. No rig an individual can buy runs it - so unlike a workstation GPU model, there's no break-even to compute. The honest answer for nearly everyone is the per-provider API cost below.
Proprietary frontier model from xAI (SpaceXAI), built with Cursor. ~1.5T-scale family, an extension of Grok 4.5 focused on long-running agents and ambitious interactive/visual work. 500K context, knowledge cutoff Feb 2026, text + image in, text out, reasoning effort low/medium/high/xhigh. Pricing: $2/1M input, $6/1M output (cached input $0.50/1M) below 200k prompt tokens; double above. Available in Grok Build, Cursor, the API, and partner gateways. Agents on Rails benchmark (Aug 2026, Le Mans round). 82.5% accuracy on 63 runs - tied with ox-alpha, behind only the Opus 5 / Kimi K3 / Fable 5 top cluster. API recall 33.3%, the best of any model that also kept a middling time (10m 50s median). At $0.778 mean cost it is strong accuracy-per-dollar.
Your workload
API cost for your workload
| Provider | Rate ($/1M) | Monthly cost |
|---|---|---|
| xAI may be stale | $2.00 in · $6.00 out | $0.05 cheapest |
Monthly cost is an estimate from list prices and your workload - verify against the provider before committing. Cached fraction applies the cache rate to that share of input.
Can you run it locally?
Grok 4.6 has no published quantization that fits a rig one person can buy, so there's no local-hardware recommendation and no break-even to compute. The honest answer is the per-provider API cost above.
