Grok 4 with real-time X/Twitter access.
xAI's Grok models have built-in access to real-time X (Twitter) data, which no other frontier lab offers. Good pick when questions depend on what's happening on X right now — brand mentions, trending topics, influencer activity. Otherwise, Grok is a solid general-purpose model competitive with GPT-5 and Claude.
XAI_API_KEYGo to console.x.ai and sign up. xAI is currently invite-friendly — most sign-ups are approved immediately.
Open Billing and add a card. xAI requires an active payment method before any API key works.
In console.x.ai, open the API Keys tab. xAI lets you create multiple keys with different ACL scopes.
Click Create API Key, name it Admaxxer, and grant it the models and endpoints permissions. The key starts with xai- and is shown once.
Open Settings then AI Providers, find the xAI (Grok) row, paste the key, and click Connect.
grok-4 is our recommended pick — best reasoning and the flagship tier. Use grok-4-fast-reasoning for faster chain-of-thought, grok-3 if you need an older stable pin.
Confirm the key starts with xai-, billing is active, and the key has the chat and models scopes granted.
Once you've pasted your key into /settings/ai-providers, hit Test. Admaxxer makes a single no-cost call against the provider's /v1/models (or equivalent) endpoint and reports back:
These are the pinned model IDs Admaxxer tests against. The model picker in chat will show these plus any live-catalog entries the provider returns.
| Model ID | Display name | Context | Tools | Best for |
|---|---|---|---|---|
grok-4 |
Grok 4 (recommended) | 256K | Yes | Flagship — best reasoning, 256K context, real-time X access. Default pick. |
grok-4-fast-reasoning |
Grok 4 Fast Reasoning | 256K | Yes | Faster reasoning-tuned variant. Good for agent loops where latency matters. |
grok-3 |
Grok 3 | 131K | Yes | Previous-gen flagship. Use as a stable pin if you need reproducibility across deploys. |
When it happens: On Connect if the key is wrong, revoked, or missing the needed scopes.
Fix: Regenerate at console.x.ai and grant it the chat and models scopes on creation.
When it happens: If billing is off or the card was declined.
Fix: Open console.x.ai/billing and confirm the payment method is active.
When it happens: Under concurrent load on grok-4.
Fix: Request a rate-limit increase in xAI console, or drop to grok-4-fast-reasoning.
When it happens: If you pick a retired Grok build.
Fix: Use grok-4, grok-4-fast-reasoning, or grok-3 — the current supported tiers.
When it happens: During peak demand — xAI capacity varies.
Fix: Retry with backoff. For mission-critical flows, fail over to a secondary provider via OpenRouter.
