Perplexity Launches Comet: An AI-Powered Browser Set to Challenge Chrome

Perplexity, well-regarded for its AI-driven search engine, is now venturing into the browser space with Comet, an AI-enhanced browser poised to disrupt Chrome's dominance. Comet's key feature is its Comet Assistant, which provides real-time webpage reasoning capabilities, allowing users to summarize YouTube videos, analyze documents, and compare products directly within the browser interface. Comet utilizes a hybrid AI architecture to optimize both speed and privacy, striking a balance between local processing and cloud-based intelligence. Currently, the browser is available to Perplexity Max subscribers. Comet's launch is expected to intensify competition with OpenAI’s rumored AI browser, as well as established browsers like Chrome, potentially transforming how users engage with the web.

Google's Gemini Upgrade: Deep Think and Agent Mode on the Horizon

Google is preparing to enhance its Gemini model with the introduction of Gemini 2.5 Pro Deep Think (kingfall). This enhanced iteration aims to deliver improved output quality, supported by backend toggles designed to fine-tune performance. While the increased complexity may lead to slightly longer response times, the anticipated improvements in accuracy and detail are expected to be substantial. Google is also actively developing an Agent Mode for Gemini, enabling autonomous task handling through Google’s A2A agent stack, empowering Gemini to independently manage intricate tasks. Additionally, Bespoke will provide personalized outputs, and a Learning Mode is being developed specifically for educational applications. The integration of the image-to-video generator for Veo 3 into Gemini will further enhance its multimedia capabilities.

Google Gemini Powers New AI Tools for Developers

Google is also strengthening its suite of developer tools by incorporating Gemini-driven AI modes into Firebase Studio. These include Ask, Agent, and Agent Auto-run features, all designed to streamline the development workflow. The Model Context Protocol and Gemini CLI provide developers with enhanced control and flexibility. While AI-generated code at Google is still evolving, these tools mark a significant advancement. Moreover, Vertex AI Memory Bank seeks to minimize latency and reduce costs by providing efficient data retrieval, further improving the developer experience.
