Show HN: Metis – An agent harness pushing DeepSeek to Opus-tier coding (82%) (github.com)

Metis, a new coding agent that integrates features of DeepSeek, has recently been launched as a standalone application for both macOS and Windows. This tool operates through a built-in Metis CLI and Server runtime, enabling it to search, remember, execute, and verify coding tasks directly across terminal and desktop environments. Notably, it boasts an innovative recursive multi-agent system that facilitates better delegation and task management, allowing for seamless transitions between planning and building workflows. The significance of Metis in the AI/ML community lies in its impressive performance improvements over existing models, achieving an accuracy of 82.02% on benchmark tasks, compared to 67.42% for other systems like OpenCode. Its architecture incorporates durable SQLite memory, allowing it to retain project knowledge across sessions, and includes automated verification gates that enhance reliability. Additionally, its extensibility with various LLM providers and customizable interfaces makes it a versatile tool for developers, setting a new standard for coding assistants and potentially accelerating software development across industries.
