OpenAI Releases Open-Source AI Models with Commercial-Grade Performance

OpenAI has open-sourced two high-performance language models under the permissive Apache 2.0 license, enabling unrestricted commercial use. The gpt-oss-120b requires an 80GB GPU while the gpt-oss-20b runs on consumer hardware with 16GB memory, delivering capabilities rivaling OpenAI's proprietary GPT-4o-mini.

The 120-billion parameter model employs a mixture-of-experts architecture activating only 5.1B parameters per token, achieving benchmark parity with premium offerings. Both models support 128K-token contexts, excelling in mathematical reasoning, coding, and medical applications.

This strategic release coincides with intensifying competition in the open-source AI sector and speculation about GPT-5's development. The MOVE democratizes access to cutting-edge AI, potentially disrupting the commercial AI landscape.
