We present ChatDev 2.0: DevAll (hereafter DevAll), a no-code platform for building, executing, and inspecting heterogeneous MAS that delivers both high expressiveness and ease of use. In terms of expressiveness, DevAll pairs a declarative executable graph abstraction with a cycle-aware execution engine, so that heterogeneous agents and dynamic and cyclic interactions can be represented and executed within a single framework. For ease of use, an integrated visual interface lets users author, run, monitor, and inspect MAS, including human-in-the-loop steps, entirely without writing code. Experiments demonstrate that DevAll reproduces state-of-the-art MAS across three representative tasks at competitive performance and without task-specific orchestration code, highlighting its effectiveness as a general-purpose platform for LLM-based MAS. DevAll is available at https://github.com/OpenBMB/ChatDev.", "url": "https://wpnews.pro/news/chatdev-2-0-a-no-code-multi-agent-platform-for-developing-everything", "canonical_source": "https://www.machinebrief.com/news/chatdev-20-a-no-code-multi-agent-platform-for-developing-eve-8gy6", "published_at": "2026-09-02 04:00:00+00:00", "updated_at": "2026-09-02 04:25:20.398333+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-tools", "ai-research"], "entities": ["OpenBMB", "ChatDev 2.0", "DevAll"], "alternates": {"html": "https://wpnews.pro/news/chatdev-2-0-a-no-code-multi-agent-platform-for-developing-everything", "markdown": "https://wpnews.pro/news/chatdev-2-0-a-no-code-multi-agent-platform-for-developing-everything.md", "text": "https://wpnews.pro/news/chatdev-2-0-a-no-code-multi-agent-platform-for-developing-everything.txt", "jsonld": "https://wpnews.pro/news/chatdev-2-0-a-no-code-multi-agent-platform-for-developing-everything.jsonld"}}
