Grok 4.5, xAI's latest flagship model, can generate a fully functional, end‑to‑end application from just one prompt, shifting AI programming evaluation from code speed to overall product completeness and token‑efficient multi‑step reasoning.
The article benchmarks OpenAI's newly released GPT‑5.6 (Sol, Terra, Luna) against Anthropic's Claude Fable 5 and SpaceXAI's Grok 4.5 by having each model independently develop a football web game in Cursor, comparing pricing, benchmark scores, development speed, bug‑fix cycles, code size, UI quality, and overall suitability for different tasks.
Released on July 8, 2026, xAI's Grok 4.5 outperforms competitors in software‑engineering benchmarks, consumes far fewer tokens, and has been praised by security researchers for its powerful vulnerability‑detection capability, while offering a $2/M‑input‑token pricing and 80 TPS inference speed.
xAI’s newly released Grok 4.5, a 1.5 T‑parameter MoE LLM, matches Claude Opus 4.7 on benchmark scores while delivering up to 80 TPS inference, cutting token costs by more than 60 % and reducing token usage to a quarter of Opus, thanks to revamped training pipelines and massive GPU resources.
SpaceXAI's Grok 4.5 arrives ahead of OpenAI's GPT‑5.6 Sol, delivering terminal‑bench scores of 83.3% and multilingual code‑fixing at 78.0%, while offering a striking $2/$6 per‑million‑token price and 80 TPS inference speed, yet still lagging behind top rivals on the hardest SWE‑Bench Pro tasks.
Recent announcements—including Grok 4.5, ByteDance’s Seedream 5.0 Pro, Meta’s Muse Image/Video, and rumored GPT‑5.6—show that AI competition is shifting from raw size and leaderboard rankings to securing default positions within real‑world workflows such as coding environments, design tools, and social content creation.
Cursor teams up with SpaceXAI to launch Grok 4.5, a model trained on real development data and engineered tasks, whose benchmark scores approach GPT‑5.5 and Opus 4.8, while Musk claims its speed rivals Opus 4.7, and the model is now priced for subscription use across desktop, web, iOS, CLI and SDK.
