Grok 3 ai - AI Language Models Tool

Overview

Grok 3 is xAI’s flagship language-model family introduced in February 2025 as an upgrade to Grok 2. xAI describes Grok 3 as trained on a much larger compute budget (the company cites roughly 10× the compute of prior models) and refined with large-scale reinforcement learning to improve multi-step reasoning, mathematics, coding, and instruction following. ([x.ai](https://x.ai/blog/grok-3)) The Grok 3 family includes full-sized Grok 3 (reasoning-enabled), a cost-efficient Grok 3 mini, and specialized “Think”/“Big Brain” reasoning modes that apply extra test-time compute for harder multi-step problems. The release also introduced DeepSearch — an AI-powered research feature that scans the public web and X (formerly Twitter) to synthesize current information for answers — and multimodal capabilities for image understanding (with voice mode announced as coming soon). ([x.ai](https://x.ai/blog/grok-3)) Grok 3 was rolled out to X (Grok) users and into xAI’s API offering, with premium X subscribers getting earlier access; xAI and third-party press reported API pricing and token limits when the API launched. While xAI highlights strong benchmark performance and an exposed chain-of-thought inspection for reasoning runs, the product has also faced safety and moderation scrutiny related to image-generation misuse, prompting platform restrictions and regulatory attention. Readers should consult official docs and recent news before production use.

Key Features

• Big Brain / Think modes: extra test-time compute for longer multi-step reasoning runs.
• DeepSearch: scans and synthesizes live web + X content for research-style answers.
• Chain-of-thought inspection: users can view intermediate reasoning steps for transparency.
• Multimodal inputs: image understanding with planned/available voice mode on mobile apps.
• Grok 3 mini: lower-cost variant for cost-efficient STEM reasoning and quick tasks.
• Improved coding: tuned for code-generation and debugging, with competitive LiveCodeBench scores.
• API access with high token limits (published API supports large contexts up to 131k tokens).

Example Usage

Example (python):

import os
import requests

# Example: send a chat request to xAI's Grok API.
# Verify model name and endpoints in the official docs: https://docs.x.ai/

XAI_API_KEY = os.environ.get("XAI_API_KEY")  # set your xAI API key in env
if not XAI_API_KEY:
    raise RuntimeError("Set XAI_API_KEY environment variable with your API key")

url = "https://api.x.ai/v1/chat/completions"  # check docs.x.ai for the current endpoint
headers = {
    "Authorization": f"Bearer {XAI_API_KEY}",
    "Content-Type": "application/json",
}

payload = {
    "model": "grok-3",                # confirm exact model id in xAI docs
    "messages": [
        {"role": "user", "content": "Explain Bayes' theorem with a short example."}
    ],
    "max_tokens": 512
}

resp = requests.post(url, headers=headers, json=payload)
resp.raise_for_status()
print(resp.json())

# NOTE: model names, endpoints, and parameters can change; always consult xAI developer docs.
# Official docs: https://docs.x.ai/ (Quickstart and API Reference).

Pricing

xAI / Grok access has been distributed via X Premium tiers and a paid Grok offering; xAI launched a developer API with per-token pricing. Press reporting (TechCrunch, April 2025) lists Grok 3 API prices around $3 per million input tokens and $15 per million output tokens for standard Grok 3 (faster tiers are priced higher), with Grok 3 Mini substantially cheaper per token. xAI also rolled Grok 3 features into X Premium/Premium+ access tiers for consumers; TechCrunch and CNBC reported Premium+ early access and SuperGrok subscription plans during launch coverage. Users should check xAI’s official pricing page and console for current commercial terms and any regional/subscription differences.
