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

NVIDIA Nemotron 3.5 Super VL is a multimodal foundation model developed for AI agents that require reasoning, visual understanding, coding, and multistep task execution. Its 120-billion-parameter mixture-of-experts architecture activates approximately 12 billion parameters per token, enabling efficient inference while maintaining substantial model capacity. The model processes text, images, documents, and video within a unified system that combines multimodal interpretation with instruction following and tool use. Its document intelligence capabilities include extracting information from tables, analyzing charts, interpreting page layouts, and processing multipage documents. Video understanding features support visual information retrieval, content review, incident analysis, and reasoning across recorded sequences. The model also supports software engineering tasks such as code analysis, error identification, debugging, testing, and recommending fixes. Developers can customize Nemotron 3.5 Super VL using NVIDIA NeMo for supervised fine-tuning, low-rank adaptation, and reinforcement learning with domain-specific data. Its inference optimizations include speculative decoding, context reuse, multi-token prediction, and NVFP4 quantization to improve throughput and reduce computational requirements. The model is available with open weights and supports deployment across compatible local hardware, enterprise data centers, and cloud infrastructure.
