Stateful Agentic Engineering Copilots with Letta: Core Memory, Shared State, Semantic Retrieval, Custom Tools, Streaming, and Portable Agent Workflows

In this tutorial, we build a stateful engineering copilot with Letta that demonstrates how agentic memory extends beyond conventional prompt-based conversations. We begin by creating inspectable core memory blocks that the agent can autonomously update, then expose those blocks for programmatic state synchronization and shared access across multiple agents. We further extend the architecture with archival vector memory for semantic retrieval, a custom server-side tool for deterministic risk est

OpenAI's latest AI models are coming to Google Cloud and Antigravity

Google would certainly prefer that everyone used its Gemini models with Google Cloud services, but soon, you'll have more options. OpenAI and Google have come to an arrangement that will see the former's frontier models arrive in Google Cloud services. Perhaps more importantly, GPT models will soon appear in Antigravity, Google's agent-powered coding tool. For enterprise customers and AI enthusiasts, OpenAI's latest model will appear in Google's "Model Garden" in the coming weeks, adding to its

Apple releases iOS and macOS 27.2 with new Siri AI features, new Music logo

Today, Apple rolled out the 27.2 updates for its operating systems, including iOS, macOS, watchOS, tvOS, visionOS, and so on. Let's start with iOS 27.2. This update is heavily focused on Siri AI. It adds a memory feature to Siri, so it can "recall your past conversations" and reference them when chatting with you. It also expands what data sources Siri can access when giving responses to include voicemails, Messages attachments, and more.Read full article Comments

Anthropic says one AI agent beats many subagents now that models can handle complexity alone

Anthropic says companies should evaluate whether they can consolidate sub-agents into a single agent that loads context on demand. In one architecture comparison, the single-agent setup ran about twice as fast. Anthropic has published a migration kit on GitHub to help teams make the transition. The article Anthropic says one AI agent beats many subagents now that models can handle complexity alone appeared first on The Decoder.

Anthropic Launches OSS Scanner, a Free AI Vulnerability Scanner

Anthropic has launched OSS Scanner, a free, opt-in vulnerability scanner for critical open-source projects. The Anthropic OSS Scanner runs the company’s strongest models, including Claude Mythos, against enrolled codebases. Reports go straight to maintainers without human review. That trade delivers faster findings, but shifts triage work onto project teams. 11 days after the October 8 launch, Anthropic reported 77 critical and 803 high model-rated findings. TL;DR Scale: 114 projec

OpenMobile-2 proves open-source smartphone agents can rival proprietary models

Smartphone agents don't get better by processing more data. They improve by training on as many different apps as possible. The researchers behind OpenMobile-2 built an open training environment with more than 110 applications, including 35 replicas of popular apps. On real Android devices, their model scores highest among open agents, the authors say.
