AI Product Updates: New Features and Releases

CoreWeave's AI research and iteration agent ARIA now renders parallel coordinates, parameter importance, run comparer and media panels live in the chat thread.

Vercel Sandbox now runs Scale AI Labs' AgentEnv evals: give an agent a task, execute it in a sandbox, and check how it performed.

Vercel Sandbox commands can now send input to running CLI tools and stdio MCP servers such as agent-browser.

A roundup of 15 Arc projects from last week, including TollyLabs' expanded MCP, TowerExchange's stablecoin execution MCP for Claude, and TryArcStocks' 63-endpoint agent API.

Claude Code version 2.1.311 is announced as about to be released, with no specific changes listed in the post.

Anthropic launched Claude Duet, a standalone AI agent meant to proactively handle work, framed as a shift from chatbots that wait for prompts to agents that take initiative.

Link balance lets users fund an agent with a set spending limit so it can buy tickets, wait for price drops, or order a shopping list unattended, rolling out to Instinct users in eligible US regions.

Cursor releases an Agent SDK that defines agents as code with Markdown prompts and TypeScript tools, deployable on hosted or self-run infrastructure, with built-in evals.

Orbio launched Sage through NEAR AI: any agent can ask yes/no, multiple-choice, or scored questions and get calibrated probabilities back, paid in CREDIT.

Nomina's MCP server is live and open source, letting models research funding-rate arbitrage strategies, with trade execution still to come.

Vercel AI Gateway now serves GPT-6.1 Terra and Terra Fast, pitched as fast models for visual reasoning, computer use, and writing with fewer factual errors.

OpenAI says GPT-6.1 Terra is now available to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, and via the OpenAI API.
