Abi

ABI, short for Agentic Brain Infrastructure, is an open source AI operating system from Naas. It connects an organization's data sources, such as CRMs, code repositories, databases and financial systems, maps the relationships between entities into a knowledge graph, and grounds AI agents in that ontology so they understand the context of the work. Naas positions it as an open source alternative to Palantir. It is aimed at technical teams that want to build and own their AI system rather than rent a closed one. ABI offers three ways in: Nexus UI for chat, agents, workspaces and the graph; an API that exposes every agent, workflow and pipeline as an endpoint; and a CLI for chatting with the supervisor agent in the terminal. The supervisor routes each request to the right model, domain agent or the knowledge graph, and supports ChatGPT, Claude, Gemini, Grok, Mistral and Perplexity through APIs, as well as local models such as DeepSeek, Qwen and Gemma through Ollama. More than 20 prebuilt domain expert agents ship with their own ontology, tools and workflows. The code is MIT licensed and can be self hosted. The pricing page lists Open Source, free forever, with full CLI access, local development and unlimited agents. Personal costs $10 per month with 350 credits included, a cloud workspace, a personal AI assistant and a Chrome extension. Pro costs $50 per user per month with 1,800 credits per user, custom assistants, team collaboration, API access and SSO. Enterprise is custom priced. Additional credits are consumed at $0.03 each for AI models and infrastructure services. Naas also offers an enterprise arrangement in which it operates ABI together with the customer.
