AI Product Updates: New Features and Releases

Weekly roundup: n8n launched an Assistant that builds, runs and debugs workflows with execution history, DeepSeek released V4.1-Flash with old model names routing to it, and three payment firms began work on shared Know-Your-Agent principles.

Algorand released AC2, an open protocol for safer AI agent approvals and credential isolation, alongside post-quantum accounts on mainnet and over 2,800 x402 endpoints.

AIHOT added Tibo reset monitoring with a calendar marking full resets and reset cards, automatic group notifications, and a keyless JSON API for use in other tools.

Google released Artemis under Apache-2.0, letting AI assistants and test suites control a real Android phone via screen reading and taps, with MCP support for Claude Code and Cursor and over 99% task completion on AndroidWorld.

Cursor replaced per-task new chats with one persistent thread where the agent remembers project context and runs subagents underneath, which the author calls the biggest AI coding UX shift this year.

Google's Antigravity platform shipped a /boost multi-agent reasoning command, interactive generative UI artifacts, and updated Git and terminal tools, alongside AlphaGenome Atlas Skills and an improved /teamwork-preview.

Pi Desktop v0.6.3 brings SoloHost better app discovery, reliability improvements, new developer tools, and AI agent compatibility for building and testing self-hosted apps.

OpenAI turned the agent runtime behind Codex into an API with automatic context compaction and recovery, native MCP and custom tools, parallel sub-agents, and a built-in Linux sandbox.

An OpenAI staffer said GPT-5.3-Codex-Spark will be retired next week, citing declining usage and significantly better models now available.

OpenAI's developer account announced the Agents API in public beta, letting developers build and run cloud agents with the Codex harness while OpenAI handles orchestration, long-running sessions, and context management.

Unity shipped an official agent plugin, available on the Codex marketplace with a one-command setup, offering 27 skills that pair with Blender MCP to generate models, rig and animate them, and autotest games.
