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
Inkling 2 Small is a general-purpose multimodal AI model developed by Thinking Machines Lab for software engineering, advanced reasoning, visual analysis, and autonomous agent applications. The model features a sparse mixture-of-experts architecture containing 594 billion total parameters, with approximately 17 billion parameters activated during inference. Its one-million-token context window supports processing large documents, software repositories, extended conversations, and complex collections of information. Inkling 2 Small accepts text and image inputs and generates text outputs, enabling visual reasoning, programming assistance, document analysis, and multimodal problem-solving. Its agentic coding capabilities support autonomous software development, code debugging, repository modifications, application creation, and verification of completed engineering tasks. The model can also perform extended research workflows involving machine learning experimentation, GPU kernel optimization, data analysis, and iterative scientific problem-solving. Configurable reasoning effort allows users to balance response speed and computational resources against the complexity of individual tasks. Thinking Machines Lab reports benchmark scores of 25.4% on FrontierCode 2.0, 72.1% on DeepSWE 1.1, and 86.3% on SWE-Bench Pro v2 Hard. Inkling 2 Small is available for inference and fine-tuning through Tinker, with model weights scheduled for release under the Apache 2.0 license after additional safety evaluations.
