OpenAI released gpt-oss-120B and gpt-oss-20B open-weight reasoning models under Apache 2.0 licensing, now available on Together AI's infrastructure. The 120B model is priced at $0.15 per 1M input tokens and $0.60 per 1M output tokens with 99.9% uptime SLA. Organizations can deploy these models without vendor lock-in, fine-tune for specialized domains, and build commercial applications with full ownership.
OpenAI released two open-weight language models called gpt-oss-120b and gpt-oss-20b under the Apache 2.0 license. The larger model contains 120 billion parameters while the smaller contains 20 billion parameters, both optimized to run on consumer hardware. Users can now deploy these models without licensing restrictions and benchmark them against similarly sized open alternatives on reasoning and tool-use tasks.
OpenAI released two open-weight reasoning models, gpt-oss-120b and gpt-oss-20b, licensed under Apache 2.0. The models have 120 billion and 20 billion parameters respectively. Developers can now access these models for reasoning tasks under open licensing terms.
Researchers tested open-weight large language models by fine-tuning them to maximize capabilities in biology and cybersecurity to identify potential worst-case risks. They evaluated performance across both domains to establish a frontier of what malicious actors could achieve with publicly available model weights. The findings inform decisions about which models should remain restricted versus released as open weights.
A company released its most capable open-weights AI models to increase access to advanced AI technology globally. The models are available for anyone to download, modify, and deploy without restrictions on commercial or research use. This shift aims to distribute AI capabilities more broadly beyond companies with large computational resources.
