An Infographic Overview of Architecture, Market Implications, and Competitive Landscape
MoE combined with 4‑bit quantization delivers high efficiency, enabling single‑GPU deployment while maintaining competitive performance, and a dramatic cost advantage that fuels open‑weight adoption.
OpenAI’s decision to release gpt‑oss‑120b and gpt‑oss‑20b under an Apache 2.0 license marks a calculated pivot. By giving developers on‑premise flexibility, OpenAI aims to lead the democratization wave, build an ecosystem that offsets API revenue, and position itself as a thought leader in safety and interpretability through raw Chain‑of‑Thought access. This move also sends a strong signal to competitors, forcing a re‑evaluation of how much capability is safe or desirable to open‑source.
