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.

Description

GLM-5.3 is Z.ai’s advanced coding and agentic reasoning model built through scaled post-training on top of the GLM-5.2 base model. The release focuses on frontier coding, long-horizon software engineering, agent tasks, cyber evaluation, and reinforcement learning at scale. GLM-5.3 improves significantly over GLM-5.2 on complex coding benchmarks, real-world engineering environments, Terminal Bench 3.0, DeepSWE, Agents’ Last Exam, and Z.ai’s internal Code Bench. The model is trained on environments that resemble real professional work, including tasks involving codebases, infrastructure, documentation, compute clusters, experiments, bottleneck diagnosis, implementation, testing, and measurable optimization. Z.ai’s post-training stack includes IndexShare for efficient long-context processing, SAO for reinforcement learning on long-horizon tasks, and slime for large-scale asynchronous training. GLM-5.3 supports three thinking effort levels, including low, high, and max, with max recommended for coding tasks. The model also demonstrates emergent cyber capabilities across vulnerability discovery and exploitation benchmarks, prompting continued safety evaluation and hardening before weights are released. GLM-5.3 can be used through the GLM Coding Plan, ZCode, Claude Code, OpenCode, and other coding agent workflows. By combining stronger coding performance, long-horizon task execution, post-training scale, cyber evaluation, reasoning effort controls, and coding-agent integrations, GLM-5.3 supports advanced developer and research workflows.
