Google's ai-generated answers often inaccurate, New York Times investigation reveals.

Google's ai-generated answers often inaccurate, New York Times investigation reveals. The reliability of summaries produced by artificial intelligence has once again become a major concern. This issue is all the more crucial as it pertains to information access for a vast proportion of the global population. A comprehensive study, conducted by The New York Times in collaboration with the startup Oumi, provides essential clarification on this matter. This investigation utilized a corpus of 4,000 questions to precisely evaluate the performance of AI...

Oumi aims to simplify and automate custom AI model development.

Oumi aims to simplify and automate custom AI model development. Oumi PBC, a startup promoting an open artificial intelligence platform built in concert with researchers from some of the world's most prominent universities, today introduced a platform designed to automate the development of custom AI models, positioning it as a way for enterprises to move beyond reliance on large, general-purpose offerings. The announcement builds on what the company says is the momentum its earlier open-source project has built, including nearly 9,000 positive ratings on GitHub and adoption by dozens of research institutions. The new platform targets a broader audience, particularly enterprise teams that lack the time or expertise to build models from scratch. The company's pitch centers on automating what has traditionally been a complex, multistep process. Enterprises increasingly want to move away from large, closed models toward "small language models," specialized alternatives tailored to their specific needs, said Chief Executive Manos Koukoumidis (pictured). "We've seen a wave of enterprises that started with large, off-the-shelf models but now want to move to open specialized SLMs," which offer benefits such as greater relevance to specific projects, lower cost and lower latency, Koukoumidis said. That transition has been slowed by the difficulty of building custom models, a process that can take months, he said. End-to-end automation. Oumi's platform is designed to address that barrier by automating the end-to-end workflow, including data generation, evaluation, training and iteration, which are "all the steps that an AI engineer takes to develop a custom model," Koukoumidis said. The company claims the system can build custom AI models up to 100 times faster than conventional processes, reducing weeks or months of human effort to hours or minutes. Oumi said it can also reduce the technical barriers to model generation by allowing users to define a task in natural language. "All you need to do is say, 'I want to build a model,' and then you kick it off," Koukoumidis said. The platform then automates key tasks such as defining evaluation metrics, generating synthetic data and refining models based on performance gaps. "It analyzes the results for you, automatically synthesizes data, fine-tunes the model and keeps iterating," he said. "It automates all the steps of an engineer." The system supports a wide range of open models. Pricing is based on usage, including compute and tokens for training and inference. Oumi said the cost is offset by reduced engineering effort. "The amount of human effort that it saves is much higher than the bill you're going to get to train," Koukoumidis said. Oumi, which operates as a public benefit corporation, frames the platform as part of a broader effort to decentralize AI development. Koukoumidis said the company's goal is to "democratize the use of AI and put the future of AI in the hands of enterprises." Photo: oumi.

Ai Lie Detector: How Halloumi’S Open-Source Approach To Hallucination Could Unlock Enterprise Ai Adoption

Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn More. In the race to deploy enterprise AI, one obstacle consistently blocks the path: hallucinations. These fabricated responses from AI systems have caused everything from legal sanctions for attorneys to companies being forced to honor fictitious policies. Organizations have tried different approaches to solving the hallucination challenge, including fine-tuning with better data, retrieval augmented generation (RAG), and guardrails. Open-source development firm Oumi is now offering a new approach, albeit with a somewhat ‘cheesy’ name.The company’s name is an acronym for Open Universal Machine Intelligence (Oumi). It is led by ex-Apple and Google engineers on a mission to build an unconditionally open-source AI platform.On April 2, the company released HallOumi, an open-source claim verification model designed to solve the accuracy problem through a novel approach to hallucination detection
