🔥 New! ChatLLM - Abacus AI Agent

Company

About Us

Abacus.AI builds the state-of-the-art agentic platform for work: frontier models, autonomous agents and an organizational memory that let a company run on AI rather than merely use it. Thousands of enterprises, including several of the Fortune 500, and 3 million professionals and small businesses run on Abacus.AI.

What we build

Abacus.AI Enterprise

Abacus.AI Enterprise exists to maximize revenue and efficiency. State-of-the-art agents connect to your systems of record and take mission-critical processes end to end, from pipeline and pricing to operations and support, with a person in the loop exactly where you want one. Beneath them is an AI brain that learns across the organization: every document, decision and workflow compounds into shared institutional knowledge, so each agent starts where the last one left off. Security and compliance are the foundation rather than a feature: single sign-on, granular permissions, full audit trails, and deployment in your cloud or ours.

Research

Our AI research lab works on model capability and how to measure it. LiveBench, a contamination-free benchmark that can't be gamed, is widely used in the industry and serves as an objective benchmark to score AI models. The benchmark also serves as a reference to our agentic platform, which uses the best model for the task and optimizes for efficient human-agent teams.

Our Smaug line of models is fine-tuned for agent work on human-curated traces and synthetic data grounded in hard examples, then released on Hugging Face. We work with top enterprises to create custom models that may be plugged into our state-of-the-art agentic platform.

Our mission is simple: give every professional and every enterprise a super assistant that automates all their work.
