    Observational Memory: The Human-Inspired Memory System for AI Agents, with Tyler Barnes

    Tyler Barnes, founding engineer at Mastra, introduces Observational Memory. It is a new memory system for AI agents that achieves state-of-the-art results on LongMemEval with a completely stable context window. Unlike semantic recall (which uses RAG and invalidates prompt caching), Observational Memory compresses conversations into dense observations while maintaining a stable, fully cacheable context. The result: 94.87% accuracy on LongMemEval with GPT-5 mini. This is the highest score recorded by any memory system to date. In this conversation, Tyler explains how the system works, why it outperforms raw context, and how you can integrate it into your agents in under 20 minutes. We also dive into the research, the benchmarks, and what's next for Observational Memory. 🧰 RESOURCES MENTIONED Observational Memory Launch Blog: https://mastra.ai/blog/observational-memory Full Research Breakdown: https://mastra.ai/research/observational-memory Tyler Barnes on X: https://x.com/tylbar Tyler's Announcement Post (Feb 9 ): https://x.com/tylbar/status/2020924183979397512 📚 MASTRA RESOURCES Mastra: https://mastra.ai Learn Mastra in the world's first MCP-Based Course: https://mastra.ai/course Principles of Building AI Agents (Book): https://mastra.ai/book Patterns for Building AI Agents (New Book): https://mastra.ai/blog/patterns-book https://docs.google.com/forms/d/e/1FAIpQLSduJjc515f6RZJqtkR2ByqJZrB0iP8B7SUKnjjZE9IajH_I8w/viewform MASTRA? Mastra is an open-source TypeScript framework designed for building and shipping AI-powered applications and agents with minimal friction. It supports the full lifecycle of agent development—from prototype to production. You can integrate it with frontend and backend stacks (e.g., React, Next.js, Node) or run agents as standalone services. If you’re a JavaScript or TypeScript developer looking to build an agentic or AI-powered product without starting from first principles, Mastra provides the scaffolding, tools, and integrations to accelerate that process. 00:00 – Intro 00:26 – The Origin Story 01:14 – Previous Memory Systems: Semantic Recall vs Working Memory 02:23 – How Observational Memory Works 03:52 – Human-Inspired Memory System 06:11 – Buffered Observations 06:32 – Research & Benchmarks 10:34 – Live Demo 13:57 – No More Compaction Hell 15:08 – Performance & Cost Benefits 16:42 – Shipped Code vs Research Papers 17:33 – Future Roadmap & Next Ideas

    AI NEWS - Model Wars: Opus 4.6 vs GPT-5.3-Codex + Seedance 2.0 Redefines AI Video

    Shane and Abhi cover top AI stories. This week was absolutely massive! Anthropic aired Super Bowl ads mocking OpenAI's decision to put ads in ChatGPT, Opus 4.6, and GPT-5.3-Codex launched within 15 minutes of each other, and then ClawHub dropped a bombshell: 11.9% of the entire marketplace is malware. We cover everything: Anthropic's competitive jabs, the model war benchmarks, Claude's 1M token context, OpenAI's Frontier platform, the security crisis that's reshaping how people think about agent marketplaces, Kimi K2.5's domination on OpenRouter, ElevenLabs' $500M raise at $11B valuation, and the explosion of AI video generation tools. Plus: Perplexity's Model Council, Roblox 4D generation, Mistral's Voxtral Transcribe 2, and why Swyx finally admits evals actually help. AI Agents Hour is a weekly livestream hosted by Mastra CPO Shane Thomas and CTO Abhi Aiyer. Airing Mondays at 12PM Pacific on YouTube and X, the show covers breaking AI news, agent development techniques, and features interviews with industry experts building AI applications today. 🧰 RESOURCES MENTIONED Anthropic Super Bowl ads: https://x.com/tomwarren/status/2019039874771550516 Opus 4.6 launch: https://x.com/claudeai/status/2019467372609040752 GPT-5.3-Codex launch: https://x.com/sama/status/2019474754529321247 ClawHub malware report: https://x.com/aakashgupta/status/2019885557221061026 Kimi K2.5 #1 on OpenRouter: https://x.com/openrouterai/status/2020199664746971195 ElevenLabs $500M raise: https://x.com/elevenlabsio/status/2019048384011854087 Perplexity Model Council: https://x.com/perplexity_ai/status/2019444886114824219 📚 MASTRA RESOURCES Mastra: https://mastra.ai Learn Mastra in the world's first MCP-Based Course: https://mastra.ai/course Principles of Building AI Agents (Book): https://mastra.ai/book Patterns for Building AI Agents (New Book): https://mastra.ai/blog/patterns-book https://docs.google.com/forms/d/e/1FAIpQLSduJjc515f6RZJqtkR2ByqJZrB0iP8B7SUKnjjZE9IajH_I8w/viewform   MASTRA?
