  • In a groundbreaking move, Together AI has announced the availability of two revolutionary open-weight reasoning models, gpt-oss-120B and gpt-oss-20B. These state-of-the-art models, released under Apache 2.0 licensing, promise to democratize AI deployment across industries, communities, and countries globally.

    Developed by OpenAI, these models have undergone rigorous testing and evaluation, including safety training and fine-tuning exercises, to ensure they meet the highest standards for enterprise deployment. The development process was informed by extensive listening sessions across the globe, with feedback gathered from emerging markets, resource-constrained sectors, and smaller organizations.

    According to Together AI, gpt-oss-120B and gpt-oss-20B are "purpose-built open-weight reasoning models" designed specifically for reasoning tasks. These models differ significantly from scaled-up versions of existing models, instead offering a new paradigm for open-source AI development.

    The launch of these models marks a significant milestone in the evolution of open-source AI, enabling developers and researchers to access cutting-edge reasoning capabilities without barriers. With Together AI's proven infrastructure and comprehensive developer tooling, users can now fine-tune, distill, and deploy these models with ease.

    "The availability of gpt-oss-120B and gpt-oss-20B on Together AI's production-ready infrastructure is a game-changer for the open-source AI community," said Nick Huber, AI Ecosystem Lead at Quora. "We've been consistently impressed by Together AI's ability to quickly provide us with access to the latest open source models - often on day 1 of release - all while delivering exceptional performance and cost-efficiency."

    This move is expected to have far-reaching implications for industries such as government, education, and research, where reasoning capabilities will be invaluable. Moreover, emerging markets and resource-constrained sectors will benefit from the accessibility and affordability of these models.

    With Together AI's commitment to open-source innovation, developers and researchers can now unlock the full potential of gpt-oss-120B and gpt-oss-20B, pushing the boundaries of what is possible in AI-driven applications. As the frontier AI cloud continues to expand its capabilities, we can expect even more groundbreaking developments on the horizon.
