# 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]](/wiki/raw/articles/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](/wiki/multi-agent-orchestration). [[source: anthropic-multi-agent-research-system-2025]](/wiki/raw/articles/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](/wiki/agent-containment-and-blast-radius).

## Claude Managed Agents Platform
In 2026, Anthropic launched [claude managed agents](/wiki/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.
