SpaceXAI Unveils Grok 4.7: Enhanced AI Performance at an Unchanged Price

Introducing Grok 4.7: A Leap Forward in AI Capabilities

The central development is this: SpaceXAI has officially launched Grok 4.7, its latest and most powerful artificial intelligence model designed to excel in complex coding, sophisticated agentic tasks, and extensive knowledge work. This new flagship model arrives with significant architectural enhancements and a longer, more rigorous training regimen, yet remarkably maintains the same competitive pricing and operational speed as its predecessor, Grok 4.6. Developers and enterprises can now leverage a more intelligent and robust AI solution without an increase in cost, marking a significant step in accessible advanced AI.

What’s New Under the Hood?

Meanwhile, Grok 4.7 isn’t just an incremental update; it features several fundamental improvements that contribute to its enhanced performance:

• A New, Larger Base Model: Unlike previous iterations, Grok 4.7 is built upon an entirely new, more expansive foundational architecture, moving beyond the Grok 4.6 base.
• Extended Reinforcement Learning: The model underwent a longer reinforcement learning (RL) run, with a task mix heavily weighted towards problems requiring many hours to complete, leading to deeper understanding and problem-solving capabilities.
• Improved Self-Verification and Long-Context Handling: SpaceXAI reports that Grok 4.7 is designed to check its own work more carefully, leading to greater accuracy and significantly better handling of long-context prompts.
• Native Grok Bot Harness Support: The model was specifically trained to understand and integrate seamlessly with the Grok Bot harness, optimizing its performance for conversational and knowledge-based applications.

Key Technical Specifications

Grok 4.7 boasts impressive technical specifications, making it a versatile tool for a wide range of applications:

• Model Name: grok-4.7
• Context Window: A substantial 500,000 tokens, allowing for incredibly long and complex inputs.
• Knowledge Cutoff: May 2026, ensuring access to very recent information.
• Modalities: Supports both text and image input, with text output.
• Reasoning Effort: Offers flexible reasoning levels: low, medium, high (default), and xhigh.
• APIs: Accessible via Responses API and Chat Completions.
• Tools: Integrates function calling, web search, X search, and code execution capabilities.

Benchmarking Grok 4.7’s Performance

In practical terms, In comparative benchmarks against leading models like Grok 4.6, GPT-5.6 Sol Max, and Fable 5.1 Max, Grok 4.7 demonstrates significant advancements, particularly in areas crucial for professional and development tasks.

Where Grok 4.7 Excels

• EEBench: Achieved a leading score of 64.0%, an 11-point increase over Grok 4.6.
• Harvey Legal Agent Benchmark: Scored 19.6%, substantially outperforming Fable 5.1 Max (6.7%) and GPT-5.6 Sol Max (2.5%).
• Terminal-Bench 4.0: Showed a remarkable jump from 20.3% (Grok 4.6) to 38.0%.
• GDPval: Scored 1,695 Elo at xhigh effort, improving on Grok 4.6’s 1,605. SpaceXAI also notes its superior ability in document and presentation creation.

Competitive Landscape and Price-Performance

While Grok 4.7 shows strong improvements, it operates in a highly competitive market. Fable 5.1 Max still leads in four out of seven benchmarks, including a top score on Terminal-Bench 4.0, and GPT-5.6 Sol Max holds the highest DeepSWE v1.1 result. However, Grok 4.7’s true strength lies in its exceptional price-performance ratio.

It offers enhanced capabilities at a fraction of the cost of its rivals; for instance, Fable 5.1 Max costs 5x more for input and approximately 8.3x more for output, while GPT-5.6 Sol Max is 2x more for input and 3.3x more for output. This positions Grok 4.7 as a highly cost-effective option at the frontier of AI innovation.

Enhanced Safety and Cybersecurity Measures

For example, Grok 4.7 introduces an entirely new safeguard stack, which SpaceXAI touts as its strongest yet in terms of refusal capabilities and resistance to jailbreaking attempts.

• Biosafety: It topped LatchBio’s biosafety benchmark with a score of 62.4%.
• HackerBench v0.3: On SpaceXAI’s own benchmark for risky cyber tasks, the model allowed only 3.3% of risky dual-use prompts to pass, demonstrating robust control while still supporting legitimate security research. Select cybersecurity partners are now being granted invite-only access to its red-team capabilities for advanced defense research.

Pricing and Availability

Grok 4.7 is designed for broad accessibility, maintaining its predecessor’s pricing model.

• Standard Grok 4.7: Available at $2 per million input tokens and $6 per million output tokens.
• Availability: It can be accessed through the xAI API, Cursor (on all plans), Grok Build (where it is the default model), OpenRouter, Vercel, and Cloudflare.
• Grok 4.7 Fast: For users requiring even greater speed, Grok 4.7 Fast offers twice the output speed at twice the price. This variant is exclusively available in Cursor and Grok Build and is not accessible via the public xAI API or Grok Build’s free tier.
• Regional Endpoint: A US regional endpoint is available at https://us.api.x.ai/v1, incurring a 10% premium for inference kept within the United States.
