Description

Grok 4.5 is SpaceXAI’s smartest model, designed to excel at coding, agentic workflows, engineering tasks, and knowledge work. The model was trained on large-scale datasets covering coding, science, engineering, and math, with additional reinforcement learning focused on multi-step software engineering. It is built to perform well on real engineering workflows, including debugging, terminal-based tasks, complex code generation, Rust and C/C++ development, and app building from minimal prompts. Grok 4.5 is served at fast-model speeds while using fewer output tokens on comparable coding tasks, helping teams complete technical work more quickly and cost-effectively. The model is also available in Grok Build, where it can help create Excel models, PowerPoint presentations, Word documents, diagrams, business review decks, and research-supported productivity assets. Developers can access Grok 4.5 through the SpaceXAI API, Cursor, and Grok Build, with simple API key setup and support for direct integration into coding and automation workflows. Its pricing is positioned for high-intelligence work at scale, with per-million-token rates for both input and output usage. Grok 4.5 is also trained for agentic execution, allowing it to handle longer technical rollouts and multi-step problem solving more effectively. For developers, engineering teams, and knowledge workers, Grok 4.5 provides a powerful AI model for software creation, office automation, technical reasoning, and production-grade agent workflows.

Description

Solar Pro 4 is an advanced AI model designed to effectively complete real-world tasks such as document analysis, tool execution, and deliverable production, ceasing operations when there is insufficient evidence. This model is specifically tailored for extensive and intricate workloads that span multiple documents, run commands in a terminal, and coordinate numerous tool interactions over several steps. With a remarkable 512K context window and the capacity for up to 128K output tokens, it enables the seamless incorporation of contracts, reports, and data files into a single workflow without the need for division. It can process both input and output in English, Korean, and Japanese, while users have the flexibility to adjust reasoning levels for either in-depth analysis or swift, real-time responses. Designed for precision, Solar Pro 4 maintains accuracy across lengthy documents, multi-turn tool applications, and terminal operations, ensuring that values and conclusions remain consistent throughout sequential deliverables, including Excel spreadsheets, comprehensive reports, and presentation slides. Moreover, its architecture supports collaborative projects by allowing teams to work simultaneously on various aspects of a task, enhancing overall productivity and efficiency.
