OpenAI Releases gpt-oss Language Models

OpenAI has introduced two new open-weight language models, gpt-oss-120b and gpt-oss-20b. These models are designed to deliver strong performance in real-world applications while maintaining low operational costs. Both models are available under the Apache 2.0 license, allowing for flexible use. Notably, they outperform similar-sized open models on reasoning tasks and demonstrate effective tool use.
