History
Grok 3 Beta became available via the xAI API on 2025-04-09.
Training & availability
Training data has a knowledge cutoff of 2025-02-28 — information about events after that date is unlikely to appear in the model's responses. xAI has not released the underlying model weights — access is via their hosted API only.
Capabilities
-
Context window: 131K tokens.
-
Input modalities: text.
Limitations
-
The knowledge cutoff is 13 months old — this model will not know about recent events, releases, or API changes.
-
Text-only — cannot process images, audio, or video inputs.
Pricing
- Input: $3.0000 per 1M tokens
- Output: $15.0000 per 1M tokens

Quick start
Minimal example using the OpenRouter API. Copy, paste, replace the key.
from openai import OpenAI
client = OpenAI(
base_url="https://openrouter.ai/api/v1",
api_key="sk-or-...",
)
resp = client.chat.completions.create(
model="xai/grok-3-beta",
messages=[{"role": "user", "content": "Explain quantum computing in one sentence."}],
)
