Another day, another large language model, but news that OpenAI has released its first open-weight models (gpt-oss) with Apache 2.0 licensing is a bigger deal than most. Finally, you can run a version of ChatGPT offline and for free, giving developers and us casual AI enthusiasts another powerful tool to try out.
As usual, OpenAI makes some pretty big claims about gpt-oss’s capabilities. The model can apparently outperform o4-mini and scores quite close to its o3 model — OpenAI’s cost-efficient and most powerful reasoning models, respectively. However, that gpt-oss model comes in at a colossal 120 billion parameters, requiring some serious computing kit to run. For you and me, though, there’s still a highly performant 20 billion parameter model available.
