By OpenAI has officially brought its AI models to AWS for the first time in the cloud AI landscape. Announced on August 5.
This partnership means AWS customers can now have the power of OpenAI models directly within their existing cloud environment.
What makes it even more exciting is that these GPT-OSS models come with open weights under the Apache 2.0 license. That gives developers full freedom to fine-tune on laptops or private servers, boosting performance and maintaining data privacy.
The larger model, gpt-oss-120B, rivals the performance of OpenAI’s o4-mini and can run efficiently on a single GPU. Meanwhile, the smaller gpt-oss-20B is optimized to run on devices with just 16GB VRAM, making advanced AI more accessible.
AWS claims these models are up to three times more cost-effective than competitors like Google’s Gemini and OpenAI’s API models.
For developers, this isn’t just another model drop; it’s a new era.
This launch is a strategic move by AWS, which until now relied primarily on Anthropic’s Claude models for generative AI. This marks a major turning point not just for AWS, but for the cloud AI industry as a whole.
