Grok 2 is xAI's conversational model — the one powering Grok on X. Blunter and more willing to take a stance than the big-lab models, with its own ingest of recent events. On Faceb.ai you get it without a Premium X subscription.
Less hedged, more opinionated tone

Similar ballpark to GPT-4o per message.
Grok 2 is xAI's conversational model — the one powering the Grok assistant on X (formerly Twitter). Released in August 2024, positioned as less filtered and more willing to take a stance than the big-lab models.
No. Faceb.ai gives you Grok 2 on your regular plan — no X subscription required.
You get 50k credits on signup. A Grok 2 message is in the GPT-4o cost ballpark, so the bonus covers a handful of messages.
Grok is tuned to be more opinionated and less hedged. Some prompts that GPT-4o refuses or waffles on, Grok will answer directly. Quality-wise it's in the frontier tier but slightly behind GPT-4o and Claude on benchmarks.
131,000 tokens — comparable to GPT-4o.
On Faceb.ai we use the standard Grok 2 API which has the model's training-time knowledge. The real-time X/Twitter integration is an X-product feature, not available through the API.
Decent but not a top pick — for code, Claude 3.5 Sonnet and DeepSeek V3 are stronger. Grok is better for general chat and opinion-heavy tasks.
Yes — model slug: x-ai/grok-2-1212. OpenAI-compatible at https://api.faceb.ai/v1.
Grok 2 Vision is a separate model; the picker has both the text-only and vision variants.
Roughly mid-2024, with periodic refreshes from xAI.
We route through the xAI API, not the X product. xAI's developer API terms don't include training on customer traffic.
As soon as xAI ships it publicly and our upstream aggregator lists it, yes.
