20‑Year‑Old Transformer Co‑author Open‑Sources a 218‑Billion‑Parameter Model

Cohere’s Command A+ model, built by Transformer co‑author Aidan Gomez and backed by Nick Frosst, packs 218 billion parameters but activates only 25 billion at inference, uses a lossless 4‑bit quantization scheme, offers native citation support, runs on a single B200 or two H100 GPUs, and is released under an Apache 2.0 license, marking a major shift toward truly open‑source, enterprise‑ready large language models.
