Description

Claude Fable 5.2 is a frontier artificial intelligence model developed by Anthropic for advanced reasoning, autonomous software development, scientific discovery, and complex professional workflows. The model improves on Claude Fable 5.1 with stronger performance in programming, visual analysis, mathematical problem-solving, and agent-driven task execution. Its software engineering capabilities support large-scale codebase analysis, feature implementation, debugging, performance optimization, automated testing, and complex software migrations. Claude Fable 5.2 can coordinate multiple AI agents to complete long-running engineering projects and delegate simpler operations to smaller language models. The model also supports scientific research, hardware design, robotics-related reasoning, data analysis, and technical investigations that require iterative experimentation and evaluation. Configurable reasoning effort allows developers to balance computational cost, response time, and problem-solving depth according to task requirements. Anthropic reports a 49.1% score on FrontierCode 2.0, 69.9% on FrontierSWE v2, and 74.2% on Humanity's Last Exam with tools. Claude Fable 5.2 generates output up to 30% faster than its predecessor and offers an optional fast mode with up to 2.5 times faster generation, alongside safeguards for high-risk cybersecurity and biological research. The model is available through Claude applications, Claude Code, Anthropic's API, Amazon Web Services, Google Cloud, and Microsoft Azure, with standard API pricing of $8 per million input tokens and $40 per million output tokens.

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.
