OpenAI Launches Open-Weight Reasoning Models Optimized for Laptop Use

/in /tarafından

OpenAI announced on Tuesday the release of two open-weight language models designed for advanced reasoning tasks and optimized to run efficiently on laptops, delivering performance comparable to its smaller proprietary reasoning models. Unlike fully open-source models, open-weight models provide publicly accessible trained parameters (weights) but do not include full source code or training data, allowing developers to run and fine-tune them locally or behind their own firewalls.

OpenAI co-founder Greg Brockman highlighted that the ability to operate these models locally offers users greater control over security and infrastructure. The two models, gpt-oss-120b and gpt-oss-20b, differ in size: the larger model runs on a single GPU, while the smaller one can run directly on personal computers. Both excel at coding, competitive mathematics, and health-related questions, having been trained on text-focused datasets with an emphasis on science and math.

Separately, Amazon Web Services (AWS) announced that OpenAI’s open-weight models are now available on its Bedrock generative AI marketplace—a first for OpenAI on the platform. Bedrock director Atul Deo praised the models as strong open-weight options for AWS customers.

This launch marks OpenAI’s first release of open models since GPT-2 in 2019, entering a competitive landscape that includes Meta’s Llama series and China’s DeepSeek-R1, both of which have influenced open-weight and open-source AI development trajectories this year.

OpenAI, backed by Microsoft and valued at around $300 billion, is currently seeking to raise up to $40 billion in a funding round led by Softbank Group.

U.S. Agency Approves OpenAI, Google, and Anthropic for Federal AI Vendor List

/in /tarafından

The U.S. General Services Administration (GSA) has approved OpenAI’s ChatGPT, Google’s Gemini, and Anthropic’s Claude as official AI vendors for federal agencies, the agency announced Tuesday. This move supports the Trump administration’s push to expand AI adoption across government sectors.

The approvals come as part of a broader AI blueprint released on July 23, which seeks to ease environmental regulations and increase AI exports to allied countries to help the U.S. maintain its technological edge over China.

With the GSA’s approval, these AI tools will be accessible to federal agencies through a platform that streamlines contracts and usage terms. The agency emphasized that it prioritizes AI models that ensure truthfulness, accuracy, transparency, and freedom from ideological bias.

President Donald Trump has described the AI race as a defining challenge of the 21st century. His administration’s AI plan includes around 90 recommendations focused on promoting U.S. AI software and hardware exports, while rolling back state laws seen as restrictive to AI innovation.

This approach contrasts sharply with the Biden administration’s “high fence” policies, which placed more stringent safeguards on AI use within federal agencies, including monitoring and assessing AI’s impact on the public. Biden also signed an executive order aimed at fostering competition, protecting consumers, and combating misinformation—measures that were later rescinded by Trump.

Orange to Harness OpenAI’s Latest AI Models for African Languages

/in /tarafından

French telecom giant Orange announced plans to leverage OpenAI’s cutting-edge AI models to advance African language technology. Despite the continent’s rich linguistic diversity—over 2,000 languages—the benefits of AI have largely bypassed African languages due to scarce data and limited computing resources, according to researchers from Cornell University and the journal Nature.

Operating in 18 African countries, Orange signed a deal last year with OpenAI to access pre-release AI models and fine-tune large language models for regional African language translation tasks. The company began deploying OpenAI’s Whisper speech model this year for speech recognition but aims to expand into more sophisticated applications with the latest models.

OpenAI’s open-weight models provide publicly accessible parameters, enabling developers like Orange to customize models for specific needs without needing the original training datasets. Orange plans to fine-tune these models using its own collected samples of African languages and roll them out locally.

Steve Jarrett, Orange’s Chief AI Officer, told Reuters the company intends to provide these fine-tuned models free of charge to local governments and public authorities. He emphasized that the initiative serves as a blueprint for bridging the digital divide through AI, fostering collaboration with local startups and communities to elevate African languages as “first-class citizens” in the AI landscape.
