What is Grok 4.5?

Grok 4.5 is an advanced AI model from SpaceXAI built for coding, agentic tasks, engineering workflows, and knowledge work. It is presented as SpaceXAI’s strongest model to date and is designed to perform well on real-world software engineering tasks rather than only short benchmark prompts. The model was trained on datasets spanning coding, science, engineering, and math, with heavy investment in data filtering, deduplication, quality scoring, and domain-focused selection. Its reinforcement learning process focuses on multi-step software engineering, technical problem solving, automated grading, model-based evaluation, and long-running agentic rollouts. Grok 4.5 can work on challenging development tasks across languages and environments, including Rust, C/C++, terminal workflows, debugging, bug fixing, and end-to-end app generation. The model is also capable of building polished applications from a single prompt, such as interactive simulations, modern interfaces, and functional web experiences. In addition to coding, Grok 4.5 supports knowledge work inside Grok Build, including Excel model creation, web research, multi-sheet formulas, PowerPoint slide design, native diagram creation, and Word document drafting. It is designed for speed and efficiency, with fast serving, strong token efficiency, and pricing based on input and output token usage. Developers can access Grok 4.5 through the SpaceXAI API console, Cursor, and Grok Build, making it usable across coding tools, productivity environments, and custom applications. The model is positioned for teams that need intelligent technical execution at a lower cost and with fewer steps than some competing frontier models. By combining engineering-focused training, agentic reasoning, fast inference, office productivity skills, and broad developer access, Grok 4.5 gives users a capable model for building, automating, debugging, researching, and shipping complex work.

What is GPT-6 Luna?

GPT-6 Luna is OpenAI’s efficiency-focused GPT-6 model for developers and users who need capable reasoning, coding, computer use, and agentic workflows at very low inference cost. It is positioned below GPT-6 Sol and GPT-6 Astra in the model family while bringing many of the GPT-6 generation’s improvements to applications that prioritize scale and affordability. The model supports configurable reasoning effort so developers can allocate additional computation to complex tasks while keeping simpler interactions fast and economical. GPT-6 Luna can power business automation across applications used for sales, marketing, finance, operations, customer support, and human resources. Its coding capabilities support work on real software repositories, including multi-step engineering tasks that require analysis, modification, testing, and iteration. Luna can also operate in computer-use environments, allowing agents to navigate graphical interfaces and complete extended workflows across software applications. OpenAI reports that GPT-6 Luna substantially improves factual reliability compared with GPT-5.6 Luna and can approach the capabilities of more expensive models on some tasks when used at higher reasoning levels. The model also benefits from GPT-6’s improved collaboration style, with clearer technical communication, less unnecessary jargon, and fewer low-value details. Enhanced prompt caching allows applications to reuse previously processed context at a discount while preserving cache reuse when reasoning effort or available tools change. These efficiency improvements make Luna suitable for high-volume agents, coding assistants, automated workflows, customer-facing applications, and other systems where per-request cost is important. GPT-6 Luna is available through the OpenAI API as gpt-6-luna, as well as through ChatGPT Work, Codex, and supported ChatGPT desktop experiences.
