OpenAI weighs funding round above $1.2T valuation

Speaking on the a16z show, OpenAI president and co-founder Greg Brockman argued developers have been "retooling the world" to make software accessible to AI agents, and that computer use offers a simpler path.

A r/ClaudeAI user created a skill for Risograph-style illustrations after seeing a Claude Opus 5 animation post, then compared outputs from GPT-6 Astra and Fable 5.1. Results were shared as a Reddit gallery.

Koa was post-trained on Nvidia's open-weight Nemotron 3 Super using a synthetic dataset drawn from nearly three decades of enterprise CRM deployments. It ships as an option in Salesforce's Agentforce platform, pitched as an open-weight alternative that uses fewer tokens and never ingests customer data.

OpenShell's dev note describes writing formal proofs with the open-source Z3 library that a policy change proposed by an agent stays inside what the operator approved. The team argues human supervision stops scaling once hundreds of agents run for hundreds or thousands of hours.

A Reddit user built a wrapper that renders Matrix-style digital rain in the terminal while the Claude CLI agent is busy. Run it as "matrix claude" with normal Claude parameters; source is on GitHub under Apache 2.0.
