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

GLM-Legal is an AI language model developed by Z.ai to support legal analysis, document review, compliance research, and autonomous legal workflows. The model is built on GLM-5.3-Flash and incorporates specialized legal training to improve performance on professional legal tasks. Its contract analysis capabilities help users examine agreements, identify problematic provisions, and recommend revisions based on specific client objectives. GLM-Legal can analyze collections of legal documents, identify contradictions between evidence sources, and connect factual findings to relevant legal arguments. The model also supports regulatory compliance research, including analysis of privacy laws, cross-border requirements, and jurisdiction-specific obligations. Its agentic architecture enables multistep legal workflows involving document ingestion, legal reasoning, source referencing, and structured deliverable generation. Integration with Z.ai's AutoClaw platform is intended to support document editing, tracked changes, comments, and other practical legal work processes. Z.ai reports that GLM-Legal achieved a 19.2% all-pass rate on Harvey's Legal Agent Benchmark and demonstrated competitive performance on LegalBench and PLawBench. The model is intended for law firms, corporate legal departments, legal technology providers, and independent practitioners seeking AI assistance with complex legal work.
