1. OpenAI Open-Sources Symphony, a Spec for Orchestrating Codex Agents on Issue Trackers

OpenAI. Symphony is an Apache-2.0 reference spec that turns a project board (Linear, Jira) into a control plane for coding agents: every open task gets an agent, agents run continuously in their own workspaces, monitor CI, and prepare diffs for human review. OpenAI says the design grew out of an internal bottleneck where engineers could juggle only three to five concurrent Codex sessions before context-switching dominated their day, and reports a 500% increase in landed PRs on some teams once orchestration was off-loaded to Symphony. The spec defines the contract a coordination service must implement, not a product — anyone can build a compliant orchestrator. Source

2. OpenAI Details the WebRTC Stack Behind Real-Time Voice

OpenAI. A new engineering post walks through how OpenAI rebuilt its WebRTC stack to deliver low-latency, globally distributed Voice AI with seamless turn-taking. The piece is one of the more detailed public looks at how a frontier lab handles transport, jitter buffering, and conversational handoff for production voice agents — relevant reading for anyone building real-time speech interfaces against the Realtime API.

3. OpenAI Launches a $4B+ Enterprise “Deployment Company” with PwC

OpenAI. OpenAI announced a tie-up with PwC to “reimagine the office of the CFO” — automating finance workflows, forecasting, and controls with AI agents — alongside reporting that OpenAI has raised more than $4 billion to seed a new enterprise-deployment joint venture. The move mirrors Anthropic’s same-day announcement of an enterprise-services company with Blackstone, Hellman & Friedman, and Goldman Sachs, and signals that the frontier labs now see distribution and integration muscle as a strategic moat rather than something to leave to consultancies.

4. Musk-OpenAI Trial Heats Up: Expert Testimony and Disclosed Texts

OpenAI. Two filings from the Musk-vs-OpenAI proceedings landed Monday. OpenAI alleges Elon Musk sent threatening texts to Greg Brockman and Sam Altman after a settlement ask, warning executives “will be the most hated men in America.” Separately, Musk’s only listed expert witness — AI researcher Stuart Russell — testified that competitive pressure on OpenAI and others is driving a dangerous AGI arms race. The case continues to be the most consequential legal venue testing how much restructuring OpenAI can do without breaking its founding promises. Source
