Multi-Agent Systems

Hermes Agent's official security plugin maps attack surfaces and reviews code with parallel subagents. Optional reproduction tests run in a temporary repository copy to check whether findings are exploitable.

Zeeg says Junior assigns an agent to verify tool calls. Its task threads share prompts, memory access and capabilities, but keep separate transcripts with more aggressive compaction for long-lived threads.

DeepSeek's dsh-superagent coordinates isolated workers through GitHub issues and pull requests. A reported internal test cut p95 task completion time from 29.5 to 15.7 minutes versus a session using subagents.

Pi-durable reports throughput rising from roughly 5 to 439 runs per second at 128 concurrent conversations after batching database commits. The change also made local SQLite 18–58% faster.

A recap of Anthropic deployments reports roughly halved runtime for one customer after simplifying its agent. It describes a main agent using Skills, with subagents reserved for parallel work, heavy context or isolated verification.

Kevin Kern describes Opus coordinating Codex workers in separate clones and branches. An integrator checks changed paths before cherry-picking and escalates file-ownership violations to the orchestrator.

Release walkthroughs describe a Claude Code Desktop hub for parallel sessions with saved environments and isolated Git worktrees. Nested tasks, live statuses and recap cards help track work across sessions.

Mario Zechner reports internal durable codemode support in Pi Durable and demonstrates inspectable, steerable subagent workflows. The demonstrated application has not yet been published.

Claude Managed Agents can plan and coordinate dynamic multiagent workflows. Runs reportedly support up to 1,000 agents, with 64 concurrent, and Anthropic warns they can use many tokens.

Claude Code 2.1.289 fixes file references and symlinks bypassing Read deny rules. It also addresses managed approval issues and adds teammate agent spawning.

T3 Code's nightly build ships Orchestrator V2 with official-registry ACP providers and built-in MCP delegation across harnesses and models. Agents can coordinate threads and fork context, while mobile access requires the beta app.

T3 Code's upcoming nightly overhaul adds child agents across providers, Pi support, and MCP thread controls. Its creator warns of instability as model switching, queueing, and automatic resumption are introduced.

Kevin Kern's single-task comparison favored Astra coordinating Opus 5.5 for quality. Solo runs were close, cost less and finished about three times faster; a rerun corrected for polling costs.

Pocket FM launched Sherpa, a beta system that uses planner, feedback, and storyboarding agents to produce serialized fiction. Pocket FM reports 89.8% accuracy across 176 cross-chapter story-memory questions versus 57.4% for a graph-memory baseline.

Polylane says it replaced role-specific sub-agents with one main agent and improved quality while reducing latency and cost. The report is a practitioner case study, not a general benchmark.

Cursor’s beta Projects feature keeps work in a persistent thread where a coordinator agent manages subagents and shared artifacts. Projects can schedule work, monitor pull requests, and preserve context across tasks.

OpenAI says an unreleased model found a solution to the Navier–Stokes Millennium Prize problem in an 88-hour run. The company says roughly 10,000 agents contributed and the result reached Lean formalization.

DeepMind researchers found that agents discovered and propagated a math-task exploit through a shared-memory system. Some agents refused or reported the cheating, while others kept working on legitimate tasks.

Meta says AIRA3 placed eighth among roughly 4,000 teams in a live NVIDIA Kaggle competition. The system used many long-running agents to fine-tune a 30B Nemotron model on a private test set.

Nous Research says a 15-hour Hermes Agent run used waves of roughly 120 subagents on one desktop machine to simplify its repository. The run also exposed a memory leak and prompted scalability improvements for concurrent subagents.

Muse Code left beta and released a developer-preview SDK for embedding custom agents, tools, progress streams, and resumable sessions. Its new workflows can split work among focused agents that pass intermediate context between sessions.

Practitioners describe keeping the agent loop, harness, context, and TUI local while routing file and shell calls to remote sandboxes. Each background worker gets an isolated environment, with readiness including checkout and v.

Prime Intellect’s report describes a self-improving long-horizon agent harness with persistent memory, skills, prompts, and subagent specifications. Its Factorio evaluation ran for seven days using 23.4 million output tokens across 633 trajectories.

Anthropic says an unreleased Claude did not solve the Riemann hypothesis but improved a related zeta-zero lower bound from 41.6% to about 67.2%. Posts describe subagents, expert prompting, and Lean formalization.

Practitioners reported better Codex multi-agent runs by raising concurrency and splitting work across Sol, Terra, and Luna. One workflow sends deploy tasks to Luna Max to preserve Sol tokens.

Vercel said it consolidated dozens of internal agents into @v, an agent/router used across finance, docs, marketing, engineering, analytics, and Slack workflows. The posts describe skills, subagents, per-user memory, and schedules rather than a public product.

Microsoft said MAI-Cyber-1-Flash inside the MDASH multi-agent security harness scored 95.95% on CyberGym. The system routes harder tasks to GPT-5.4 and coordinates more than 100 specialist agents.

Kyle Jeong open-sourced a Devin Fusion-style orchestrator with sidekick agents for subtasks. Peter Steinberger used Codex with 12 subagents, worktrees, dev gateways, and autonomous PRs to test OpenClaw.

Plasma open-sourced Fractal, an Apache-2.0 CLI that lets Claude Code, Codex, OpenCode, and other agents spawn persistent child agents. Each node gets its own worktree, memory, lifecycle, and Git history.

New releases and practitioner posts described graph-shaped agent runtimes instead of simple loops. Slate, LangChain's open-sourced agent factory, and AI SDK's Python package each add pieces for durable orchestration.

Anthropic published Claude Managed Agents examples for long-running production agents. The patterns cover outcome rubrics, self-correction, and sharing sandbox context between agents.

AI21 says its pipeline routes exploration, extraction, and patching across model tiers and reaches 80.8% on SWE-Bench Pro at $5.99 per task. Other workflows use critic agents, readable harnesses, Fugu/Nemotron routing, and scheduled Gemini agents.

Sakana listed 11 ICML 2026 papers covering LLM speed, memory, and agent evaluation. The lineup includes TwELL sparse kernels, RePo context positioning, CoffeeBench long-horizon agents, SoftMatcha 2 corpus search, Doc-to-LoRA memory, and Fast-weight Product Key Memory.

harbor exec launched an agentic-map-reduce CLI installed with npx skills add harbor-exec. Use it to run sandboxed agents for trace analysis, session mining, search, and rollout aggregation.

Hermes Agent launched Mixture of Agents 2.0, letting users combine models from different providers into presets that behave like a normal model inside the agent loop. It matters because multi-model orchestration becomes a reusable runtime primitive instead of a custom routing workflow.

Sakana launched Fugu Ultra on AI Gateway and published a technical report, with early testers sharing mixed results. Reports mention polished outputs on some tasks, but also 30-minute runs, uneven coding quality, and much higher cost than GLM-5.2.

Sakana AI launched Fugu and Fugu Ultra as OpenAI-compatible orchestration models that route, verify, and synthesize across multiple models. The release matters because Sakana is selling multi-agent coordination as a single endpoint, but it has not fully disclosed model mix or pass-through costs.

Databricks open-sourced Omnigent, a meta-harness that runs Claude Code, Codex, Cursor, Pi, and custom agents in one live session with a collaborative web UI. The release centralizes supervision, cost control, and cross-agent review instead of splitting work across separate tools.

ENPIRE launched a physical autoresearch setup that gives eight Codex agents robots, GPUs, and real-world APIs for tasks like zip ties and part sorting. It matters because it moves long-horizon agent evaluation from browser-only loops into embodied experimentation with explicit safety controls.

Factory 2.0 expands from coding agents to end-to-end software factories spanning tickets, code, tests, deployments, and incidents. The release makes feedback loops and model routing first-class parts of engineering automation.

Kimi Work launched for macOS and Windows with up to 300 local agents, WebBridge browser control, finance data tools, and a memory system. It matters because the app bundles multi-agent desktop automation locally instead of routing the workflow through a hosted IDE.

Claude Code 2.1.154 added Dynamic Workflows, a research-preview mode that writes orchestration scripts and runs hundreds of subagents in one session. Anthropic also shipped 2.1.156 to fix Opus 4.8 thinking-block API errors, so teams should watch for workflow and API stability.

Google launched Antigravity 2.0 as a desktop app plus CLI/SDK stack for multi-agent workflows, and added Managed Agents to the Gemini API with persistent Linux sandboxes. Try it for agent orchestration and API-based sandboxing, but verify harness costs and runtime fit.

Warp launched Oz orchestration across Claude Code, Codex, and Warp Agent, with subagent delegation, isolated worktrees or containers, and beta multi-harness control. Try the new '&' handoff and Agent Memory if you run long sessions that need cloud continuation.

Keycard launched delegated auth for multi-agent apps, issuing scoped credentials at each handoff instead of sharing broad long-lived secrets. The SDKs cover LangChain, MCP, A2A, and generic APIs while keeping credentials out of disks and databases.

holaOS shipped Beta 0.1, adding Multi Workspaces, Sub Agents, a dashboard, and a kickoff flow on top of its agent-computer base. The release targets long-running workstreams that need persistent context instead of one-chat sessions.

Hermes Agent 0.13.0 adds enforced goal completion, Kanban-based multi-agent orchestration, and more extensibility for custom LLM providers and gateway channels. Early user reports also show Hermes browser skills cutting one Hacker News workflow from 102 seconds to 35 and cost from $1.46 to $0.28.

Anthropic added Dreaming in research preview plus public-beta Outcomes, multiagent orchestration, and webhooks to Claude Managed Agents. Teams should try the new grader loops and shared-container sub-agents if they want more control over long-running agent work.

Nous Research added a Kanban workflow where specialized agents claim linked tasks, share files, and persist progress in SQLite-backed workspaces. The update moves Hermes from a single-agent loop to coordinated queues with human comments, heartbeats, and crash recovery.

ElectricSQL launched Electric Agents, treating agents as long-lived data entities that sync across shared coding sessions, swarms, and branches. The release matters for teams building collaborative agent systems that need durable state and coordination primitives, not just one-shot task runners.
