Grok 4.7 is Out: 2.1T Parameters That Cut API Costs in Half (Benchmark Breakdown)

SpaceXAI has officially released Grok 4.7 (grok-4.7), expanding to a massive 2.1-trillion parameter foundation that runs twice as fast at half the cost of comparable frontier models. In this comprehensive technical breakdown, we examine the verified receipts: its 38.0% score on Terminal-Bench 4.0, how it crushed Claude and GPT on the Harvey Legal Agent benchmark at 19.6%, the full arithmetic of its $2.00/1M pricing structure, and the production routing blueprint you need to deploy it in Cursor and Grok Build today. 📌 TIMESTAMPS: 00:00 - The 2.1-Trillion Parameter Shockwave 01:27 - Architecture Deep Dive: Scaling to 2.1 Trillion Parameters 03:11 - The 500k Context Window & Tiered Pricing Architecture 04:49 - The Benchmark Showdown: Terminal-Bench 4.0 & Harvey Legal 06:45 - Grok Build & Cursor Integration: The Terminal Agent Harness 08:11 - API Economics & The Frontier Disruption Curve 09:46 - The Top 1% Developer Blueprint & Final Verdict 📊 KEY BENCHMARK RECEIPTS: • Terminal-Bench 4.0 (xHigh Reasoning): Grok 4.7: 38.0% (+87% relative jump over Grok 4.6) GPT-5.6 Sol Max: 37.3% Grok 4.6: 20.3% Claude Fable 5.1 Max: 57.9% • Harvey Legal Agent Benchmark: Grok 4.7: 19.6% (Nearly 3x Claude, ~8x GPT-5.6 Sol) Grok 4.6: 15.8% Claude Fable 5.1 Max: 6.7% GPT-5.6 Sol Max: 2.5% 💰 API PRICING SCHEDULE (xAI Developer API): • Standard Grok 4.7 (under 200k context): Input: $2.00 / 1M tokens ($0.50 cached input) Output: $6.00 / 1M tokens • Standard Grok 4.7 Long-Context (200k+ context): Input: $4.00 / 1M tokens ($1.00 cached input) Output: $12.00 / 1M tokens • Grok 4.7 Fast (Dedicated Cursor & Grok Build Tier): Below 200k: $4.00 input ($1.00 cached) / $12.00 output Above 200k: $6.00 input ($1.50 cached) / $18.00 output 🔗 OFFICIAL PRIMARY SOURCES & DOCUMENTATION: • SpaceXAI Launch Announcement: https://x.ai/news/grok-4-7 • SpaceXAI Developer Documentation: https://docs.x.ai/overview • xAI API Pricing Schedule: https://docs.x.ai/developers/pricing • Grok Build Agent Reference: https://docs.x.ai/build/overview • xAI Newsroom Index: https://x.ai/news 💬 JOIN THE CONVERSATION: Are you switching your primary coding harness or agent pipelines over to Grok 4.7?
