gpt-oss-120b
OpenAI · Released Aug 2025
An open-weight 120B parameter model from OpenAI released before the gpt-oss-20b, larger and less compute-efficient than its successor.
- Strengths
- Handles long contexts and complex reasoning tasks with its 131k token window and larger parameter count.
- Best for
- Scenarios where model capacity matters more than inference speed or cost, or where the larger parameter count addresses specific capability gaps.
- Limitations
- The gpt-oss-20b successor offers better efficiency with fewer active parameters, making this model less practical for most deployments.
