Perplexity Launches “Model Council” to Cross-Validate AI Answers Across Top Models - Perplexity has launched Model Council, a new multi-model research feature that runs a single query across leading AI systems like GPT-5.2, Claude Opus 4.6, and Gemini 3.0, then synthesizes where the models agree and where they differ. Designed for high-stakes research, investment analysis, and verification workflows, the feature introduces structured cross-model validation directly within the platform.

Why it matters: As enterprises deploy AI into consequential decision processes, multi-model comparison could become an important governance guardrail — reducing blind spots, bias risk, and overreliance on any single system.

Reddit Tells Investors AI Search Could Become Major Revenue Opportunity - Reddit told investors its AI-powered search engine could become a major product and revenue opportunity as it merges Reddit Answers with its traditional search experience. Weekly active users of Reddit Answers grew from 1 million in Q1 2025 to 15 million in Q4, as the company works to modernize its interface, expand languages, and integrate dynamic AI agents.

Why it matters: As generative AI reshapes how users search for information, Reddit is positioning its community-driven data as a foundation for AI-powered answers — potentially expanding beyond advertising into new monetization streams.

The Waymo World Model: A New Frontier For Autonomous Driving Simulation - Waymo has introduced the Waymo World Model, a new simulation system designed to improve how autonomous vehicles are trained and validated. The model aims to generate realistic driving scenarios at scale, helping Waymo test rare, complex, and safety-critical situations in virtual environments before vehicles encounter them on public roads.

Why it matters: As autonomous driving companies expand operations, high-fidelity simulation is becoming essential for safety validation, regulatory confidence, and scaling robotaxi services without relying solely on real-world miles.

ElevenLabs Launches AI Audiobook Creation Toolkit - ElevenLabs has introduced Audiobooks in ElevenCreative, a toolkit that allows creators to generate, refine, and publish audiobooks using lifelike AI voices — from first draft to distribution. Users can choose instant one-click creation for rapid iteration or studio-level controls for detailed voice direction, then publish directly to ElevenReader for distribution across major listening platforms.

Why it matters: By compressing production timelines and eliminating traditional studio barriers, ElevenLabs is lowering the cost and complexity of audiobook creation — expanding access for independent authors, storytellers, and publishers scaling audio content.

Harness engineering: leveraging Codex in an agent-first world - OpenAI has introduced Harness Engineering, a framework designed to strengthen how AI systems are evaluated, tested, and improved. The approach focuses on structured testing environments that help engineers measure performance, identify failure modes, and iterate more reliably as models are deployed into real-world workflows.

Why it matters: As AI systems move into enterprise and high-stakes environments, structured evaluation frameworks like Harness Engineering could become foundational for reliability, governance, and responsible deployment at scale.

Take your training doc and prompt Claude/ChatGPT with "Turn this into a three-minute training video script for an AI-generated avatar. Only include text overlays with bullets. The avatar can be seated, standing, head-on, etc."

Save the script as a text file and go to Synthesia.io > Create New Video > Create from AI > Upload the script file, with objective and audience description

Choose a template and click Create Outline. Review the outline and follow the steps to generate your video. It should take 10-25 minutes to generate

When the video is complete, you can download and embed it somewhere like Notion or Google Docs
