Description

Claude Fable 5.1 is a frontier AI model from Anthropic built for demanding coding, research, knowledge work, and autonomous multi-step workflows. It delivers higher performance than Claude Fable 5 across benchmarks covering scientific research, terminal-based coding, business automation, computer use, multidisciplinary reasoning, and agentic software development. The model is particularly suited to long-running tasks where it must investigate problems, use tools, maintain context, verify intermediate work, and continue operating with limited supervision. Early evaluations highlighted improvements in areas such as root-cause analysis, code review, browser automation, financial research, document drafting, slide creation, and complex engineering workflows. Fable 5.1 also introduces lower cache-read pricing, which Anthropic says can reduce costs by roughly 25% for typical workloads and considerably more for context-heavy agentic tasks. Enterprise customers can use new privacy-oriented safeguard options that are designed to support zero-data-retention-style deployments while still maintaining misuse protections. Cybersecurity safeguards have also been refined to intervene less often on legitimate defensive work while continuing to restrict higher-risk activities such as exploit generation. Anthropic offers the model through Claude Code, Claude Cowork, Claude.ai, the Claude API, and supported cloud platforms. Claude Fable 5.1 is intended for developers, researchers, enterprises, and professional teams that need strong reasoning and coding performance without relying on Anthropic’s most restricted-access model tier.

Description

Fugu-Ultra v1.1 represents the enhanced multi-agent orchestration model developed by Sakana AI, designed for intricate coding tasks, agentic functions, and sophisticated reasoning capabilities. Instead of depending on a singular model, it adeptly manages a variety of cutting-edge models, strategically selecting and merging specialized agents tailored for individual tasks, all while offering a unified model interface. The latest orchestration upgrade in v1.1 features the inclusion of newer frontier models, resulting in improved performance metrics across all monitored benchmarks, achieving enhancements of up to 7.9 points compared to v1.0, with particularly notable successes on ProgramBench and Terminal Bench 2.1. In addition, Fugu can now seamlessly integrate within Claude Code through endpoints that are compatible, allowing a collaborative ensemble of models to function within the user-friendly terminal environments for coding, debugging, reviewing, and executing scripts. Users can easily set up this integration using a one-command installer on Ubuntu and macOS, while alternative manual configurations are provided for Windows and other systems, ensuring accessibility across diverse platforms. This advancement not only streamlines workflows but also enhances productivity by leveraging the strengths of multiple specialized agents.
