OpenAI has new, smaller open models to take on DeepSeek - and they'll be available on AWS for the first time

OpenAI and AWS.

• OpenAI’s new models run efficiently on minimal hardware, but haven’t been independently tested for workloads
• The models are designed for edge use cases where full-scale infrastructure isn’t always available
• Apache 2.0 licensing may encourage broader experimentation in regions with strict data requirements

OpenAI has released two open-weight models, gpt-oss-120B and gpt-oss-20B, positioning them as direct challengers to offerings like DeepSeek-R1 and other large language learning models (LLMs) currently shaping the AI ecosystem.
