Anthropic

AI safety research company developing Claude family of large language models, with research contributions in agent systems and multi-agent architectures according to the 2026 agentic engineering synthesis. [source: agentic-engineering-trends-2026-synthesis]

Research Contributions

Anthropic is cited in the 2026 synthesis as contributing to multi-agent research systems and agent harness engineering, with publications on effective harnesses for long-running agents and multi-agent research methodologies.

Multi-Agent Work

The synthesis references Anthropic’s research on multi-agent systems for breadth-first research tasks, though notes these measurements are workload-specific rather than universal.

The primary source is now in raw/: Anthropic’s 2025 account of its orchestrator-worker Research system, reporting a 90.2% improvement over single-agent Claude Opus 4 on its internal research eval and ~15× token usage versus chat. See multi agent orchestration. [source: anthropic-multi-agent-research-system-2025]

Containment & Safety Engineering

Anthropic’s 2026 engineering posts document containment architectures across claude.ai (ephemeral gVisor containers), Claude Code (human-in-the-loop sandbox plus classifier-gated auto mode), and Cowork (local VM), including disclosed failures such as pre-trust-dialog config execution and exfiltration through an allowlisted domain. See agent containment and blast radius. [source: anthropic-engineering-how-we-contain-claude-2026]

Claude Managed Agents Platform

In 2026, Anthropic launched claude managed agents, a hosted infrastructure suite decoupling agent reasoning loops from containerized sandbox execution, exposing stateful event streams for tool use, prompt caching, and human-in-the-loop permission gates.
