SpaceXAI Unveils Grok 4.7: A New Era in AI Performance and Value
SpaceXAI has officially launched Grok 4.7, positioning it as the company's premier offering for complex coding challenges, sophisticated agentic operations, and detailed knowledge-based assignments. This new model represents a substantial evolution, built upon a more expansive underlying architecture and refined through a prolonged reinforcement learning regimen. Remarkably, it maintains the identical cost structure and operational speed as the previous Grok 4.6 version, emphasizing a strong price-performance proposition.
Immediate deployment of Grok 4.7 is available as a cloud-hosted service. Developers can integrate the grok-4.7 model today through the xAI API, as well as via popular platforms including Cursor, Grok Build, OpenRouter, Vercel, and Cloudflare.
Architectural Enhancements and Core Upgrades
SpaceXAI details several key advancements that distinguish Grok 4.7 from its predecessor:
- Expanded Base Model: Grok 4.7 utilizes an entirely distinct and larger foundational model, diverging from the Grok 4.6 architecture.
- Intensified Reinforcement Learning: Its training regimen incorporated an extended reinforcement learning phase, heavily weighted towards intricate problems requiring substantial computational time for resolution.
- Improved Self-Verification and Context Management: The model now incorporates enhanced self-verification mechanisms, allowing it to scrutinize its outputs with greater precision, alongside superior handling of extensive contextual information.
- Native Grok Bot Harness Integration: Grok 4.7 was specifically engineered to seamlessly interpret the Grok Bot harness, facilitating its utility in conversational AI and complex informational tasks.
The developer documentation specifies the model's technical capabilities:
- Model Name:
grok-4.7 - Context Window: An extensive context window of 500,000 tokens.
- Knowledge Cutoff: May 2026.
- Modalities: Supports both textual and visual input, generating text-based responses.
- Reasoning Effort: Offers adjustable reasoning levels: low, medium, high (default), and xhigh.
- APIs Supported: Responses API and Chat Completions API.
- Integrated Tools: Includes robust functionalities such as function calling, web search, X platform search, and code execution.
Comparative Performance Benchmarks
SpaceXAI's launch table provides a comparative analysis of Grok 4.7 at 'xHigh' effort against Grok 4.6 'High', GPT-5.6 Sol Max, and Fable 5.1 Max. While Grok 4.7's DeepSWE score was evaluated at 'high' effort, all reported scores are from the respective vendors.
Grok 4.7 demonstrates performance enhancements over Grok 4.6 across all measured metrics. The most significant improvement was observed on Terminal-Bench 4.0, where its score climbed from 20.3% to 38.0%. Furthermore, its EEBench score increased by eleven percentage points, reaching 64.0%, the highest among the evaluated models. On Harvey’s legal agent assessment, Grok 4.7 achieved 19.6%, notably outperforming Fable 5.1 Max's 6.7%.
However, Grok 4.7 does not consistently outperform all rivals in every category. Fable 5.1 Max secured the highest scores in four out of seven benchmarks, including a 57.9% on Terminal-Bench. GPT-5.6 Sol Max maintained its lead on the DeepSWE v1.1 benchmark with a 72.7% score.
Cost presents another crucial factor in the comparison. Fable 5.1 Max incurs approximately five times higher input costs and 8.3 times greater output charges compared to Grok 4.7. GPT-5.6 Sol Max also carries a premium, costing twice as much for input and about 3.3 times more for output. SpaceXAI positions Grok 4.7 at the forefront of value for money when considering CursorBench 4.0 cost-per-task, highlighting its strong price-performance ratio.
On the GDPval metric, designed to assess professional knowledge capabilities, Grok 4.7 xhigh scored 1,695 Elo, an increase from Grok 4.6 high's 1,605. While Fable 5.1 Max leads this benchmark at 1,735, Grok 4.7 surpasses GPT-6 Astra Max, which scored 1,542. SpaceXAI also asserts Grok 4.7's enhanced proficiency in document and presentation generation.
Enhanced Safety and Cybersecurity Measures
Grok 4.7 integrates a completely re-engineered safety protocol framework. SpaceXAI characterizes this as the most robust model evaluated concerning content refusal and resistance to 'jailbreak' attempts. It achieved the highest score of 62.4% on LatchBio’s biosafety evaluation.
During assessments on the company’s proprietary HackerBench v0.3, designed for evaluating risky or malicious cyber operations, the model permitted only 3.3% of potentially risky dual-use prompts to proceed. SpaceXAI indicates that Grok 4.7 reportedly seldom impedes valid cybersecurity research. Furthermore, privileged cybersecurity collaborators are granted exclusive, invite-only access to its advanced red-teaming functionalities for defensive research purposes.
Pricing and Diverse Availability Options
Grok 4.7 is priced at $2 per million input tokens and $6 per million output tokens, consistent with its predecessor. It is accessible through all Cursor plans and serves as the default model within Grok Build. Availability extends across the Grok API, OpenRouter, Vercel, and Cloudflare.
For users requiring enhanced speed, Grok 4.7 Fast offers the identical model, deployed on accelerated infrastructure, delivering double the output speed at double the cost. This premium option is exclusively available within Cursor and Grok Build, notably absent from the public xAI API and Grok Build’s free tier.
A dedicated US regional endpoint, accessible at https://us.api.x.ai/v1, ensures that inference remains within the United States, albeit with a 10% cost premium. SpaceXAI advises implementing a prompt_cache_key for optimal cache hit reliability.
