Adept ACT-1 — Action Transformer
Adept launched in 2022 with a pointed thesis: train a foundation model to take actions in software, not just produce text. ACT-1 was the first public demo of a model that could read a Salesforce page and click buttons to accomplish a goal. Adept was acquired in 2024 — its co-founders and core tech went to Amazon — but ACT-1's vision directly informed Anthropic's Computer Use, OpenAI Operator, and Google Project Mariner.

Frequently asked questions
Is ACT-1 still available?
No. Adept was acquired by Amazon in June 2024; most of the team joined Amazon's AGI org, and the standalone ACT-1 product is no longer offered. The ideas live on in Amazon Nova Act and competitor computer-use agents.
Why is ACT-1 historically important?
It was the first well-publicized demo of a foundation model that took actions rather than producing text. That framing — 'action transformer' — seeded the entire category now dominated by Computer Use, Operator, Mariner, and Nova Act.
Was ACT-1 an LLM?
Yes, but trained with a heavier action-transcript component than conventional text LLMs, so it could predict not just words but UI actions (click this element, type this text).
