About
Arcee AI is a scrappy open-source model lab that bet nearly half its total funding on a single 33-day training run on 2,048 NVIDIA B300 Blackwell GPUs to train Trinity-Large-Thinking — a 400 billion parameter model released under Apache 2.0 license in April 2026. The model hit #1 on OpenRouter's most-used open model ranking and peaked at 80.6 billion tokens served per day — making it one of the most-used open-weight models from a non-Chinese AI lab.
ChatGPT surpassed 400M weekly active users in February 2025 and launched GPT-4o with voice, image, and real-time reasoning — the world's most-used AI product.
