The Complete GPT-OSS Guide
Everything you need to know about OpenAI's revolutionary open-weight models: gpt-oss-120b and gpt-oss-20b. From architecture to deployment, benchmarks to real-world applications.
What is GPT-OSS?
OpenAI's groundbreaking open-weight language models released under Apache 2.0 license
GPT-OSS models utilize a cutting-edge Mixture-of-Experts (MoE) Transformer architecture, activating only a subset of parameters per token for maximum efficiency.
- 117B total parameters (120b model)
- Only 5.1B active parameters per token
- 128,000 token context length
Released under Apache 2.0 license, enabling unrestricted commercial use, modification, and redistribution for maximum innovation potential.
- Commercial use permitted
- Full model weights available
