Spoken Dialogue Models (SDMs) are at the frontier of conversational AI, enabling seamless spoken interactions between humans and machines. Yet, as SDMs become integral to digital assistants, smart devices, and customer service bots, evaluating their true ability to handle the real-world intricacies of human dialogue remains a significant challenge. A new research paper from China introduced C3 benchmark directly addresses this gap, providing a comprehensive, bilingual evaluation suite for SDMs—emphasizing the unique difficulties inherent in spoken conversations. The Unexplored Complexity of Spoken Dialogue While text-based Large Language Models (LLMs) have benefited from extensive benchmarking, spoken dialogues present a distinct set of challenges: Phonological Ambiguity: Variations in intonation, stress, pauses, and homophones can entirely alter meaning, especially across languages with tonal elements such as Chinese. Semantic Ambiguity: Words and sentences with multiple meanin...

OpenAI has just sent seismic waves through the AI world: for the first time since GPT-2 hit the scene in 2019, the company is releasing not one, but TWO open-weight language models. Meet gpt-oss-120b and gpt-oss-20b —models that anyone can download, inspect, fine-tune, and run on their own hardware. This launch doesn’t just shift the AI landscape; it detonates a new era of transparency, customization, and raw computational power for researchers, developers, and enthusiasts everywhere. Why Is This Release a Big Deal? OpenAI has long cultivated a reputation for both jaw-dropping model capabilities and a fortress-like approach to proprietary tech. That changed on August 5, 2025. These new models are distributed under the permissive Apache 2.0 license , making them open for commercial and experimental use. The difference? Instead of hiding behind cloud APIs, anyone can now put OpenAI-grade models under their microscope—or put them directly to work on problems at the edge, in enterprise...

LLMs are deployed through conversational interfaces that present helpful, harmless, and honest assistant personas. However, they fail to maintain consistent personality traits throughout the training and deployment phases. LLMs show dramatic and unpredictable persona shifts when exposed to different prompting strategies or contextual inputs. The training process can also cause unintended personality shifts, as seen when modifications to RLHF unintentionally create overly sycophantic behaviors in GPT-4o, leading to validation of harmful content and reinforcement of negative emotions. This highlights weaknesses in current LLM deployment practices and emphasizes the urgent need for reliable tools to detect and prevent harmful persona shifts. Related works like linear probing techniques extract interpretable directions for behaviors like entity recognition, sycophancy, and refusal patterns by creating contrastive sample pairs and computing activation differences. However, these methods st...

In this tutorial, we explore how to integrate Microsoft AutoGen with Google’s free Gemini API using LiteLLM, enabling us to build a powerful, multi-agent conversational AI framework that runs seamlessly on Google Colab. We walk through the process of setting up the environment, configuring Gemini for compatibility with AutoGen, and building specialized teams of agents for research, business analysis, and software development tasks. By combining the strengths of structured agent roles and real-time LLM-powered collaboration, we create a versatile system that can execute complex workflows autonomously.

In today’s data-driven world, valuable insights are often buried in unstructured text—be it clinical notes, lengthy legal contracts, or customer feedback threads. Extracting meaningful, traceable information from these documents is both a technical and practical challenge.  Google AI’s new open-source Python library, LangExtract , is designed to address this gap directly, using LLMs like Gemini to deliver powerful, automated extraction with traceability and transparency at its core. Key Innovations of LangExtract 1. Declarative and Traceable Extraction LangExtract lets users define custom extraction tasks using natural language instructions and high-quality “few-shot” examples. This empowers developers and analysts to  specify exactly which entities, relationships, or facts to extract, and in what structure . Crucially, every extracted piece of information is  tied directly back to its source text —enabling validation, auditing, and end-to-end traceability. 2....

Introduction Galileo is an open-source, highly multimodal foundation model developed to process, analyze, and understand diverse Earth observation (EO) data streams—including optical, radar, elevation, climate, and auxiliary maps—at scale. Galileo is developed with the support from researchers from McGill University, NASA Harvest Ai2, Carleton University, University of British Columbia, Vector Institute, and Arizona State University. Galileo aims to provide a unified, generalist solution for critical applications like agricultural land mapping, disaster response, and environmental monitoring. In contrast to prior remote sensing models limited to a single data type or scale, Galileo flexibly fuses multiple sensing modalities and is designed to recognize phenomena ranging from tiny objects (such as fishing boats, measuring just 1–2 pixels) to vast, slowly changing features like glaciers. Key Features and Architecture Multimodal Transformer Design Galileo is based on a Vision Tran...

The tides have turned in the enterprise AI landscape. According to Menlo Ventures’ 2025 “Mid-Year LLM Market Update,” Anthropic’s Claude has overtaken OpenAI as the leading language model provider for enterprise, now capturing 32% of market share compared to OpenAI’s 25%—a dramatic reversal from OpenAI’s dominant 50% share just one year ago. This is more than a leaderboard shuffle: it’s a testament to the maturation of enterprise AI and a signal for what businesses truly value in this next phase. Anthropic’s Strategic Acceleration Anthropic has charted a meteoric rise, catapulting revenues from $1B to $4B in just six months—largely on the strength of enterprise adoption by discerning, high-value customers. Rather than chasing ubiquity, Anthropic doubled down on the complex needs of large organizations, focusing on areas where AI adoption is not a curiosity but a necessity. With robust logic, structured reasoning, and rigorous regulatory compliance, Claude has become the preferred pa...
