Grok
Snappy + real-time — the X-native model.
What is Grok?
Grok is the xAI frontier model with a 256,000 tokens context window, released 2026-04. Tagline: Snappy + real-time — the X-native model..
Pricing detail. Bundled with X (Twitter) Premium subscription — no per-token bill for end users, no individual API pricing for the chat product.
How I use it inside the Agent OS. Used for real-time content workflows where the model needs current X timeline context. Standalone bench scoring pending.
What I built with Grok
Every model on Goldie Bench gets the same fixed prompt set — one shot, single HTML file out — and I score the result 0–10 inside the Agent Operating System. Here's what Grok shipped on the bench: 13 one-shot demos across 256,000 tokens of context. Of those, 0 are scored against the field with my honest 0–10 from the source guides at agentos.guide.
Strengths
- Real-time access to X timeline data — unique signal no other model has
- Snappy latency on shorter prompts
- 256K context window keeps pace with the open-weights field
Trade-offs
- 13 demos on the bench but zero have curated 0–10 verdicts yet — currently unranked
- API access is gated behind X Premium, awkward for backend agent loops
Best for
- Workflows that need live X / Twitter context
- Snappy prompts where latency matters
- Researchers comparing X-native models against the rest of the field
