# OpenAI Releases Open-Weight Reasoning Models Under Apache 2.0 License

OpenAI has announced the release of two new open-weight AI models: gpt-oss-120b and gpt-oss-20b. The company shared the news via its official Twitter account, marking a significant shift in its approach to model accessibility.

**What's New**

The two models differ in size, with gpt-oss-120b containing 120 billion parameters and gpt-oss-20b featuring 20 billion parameters. Both are described as "reasoning models," suggesting they're designed for complex problem-solving tasks rather than simple text generation.

**The License Change**

Most notably, these models are released under the Apache 2.0 license, one of the most permissive open-source licenses available. This means developers can use, modify, and distribute the models with minimal restrictions, though
