In a strategic pivot, OpenAI has released its first open-weight large language models since 2019—gpt-oss-120b and gpt-oss-20b—under the permissive Apache 2.0 license. This empowers developers to freely run, modify, and monetize the technology, addressing criticisms of proprietary dominance and fueling innovation in emerging markets. Early tests reveal near-parity with closed models but flag high hallucination risks, signaling a complex new chapter for accessible AI.
