gm legends, happy Thursday.
OpenAI open-sourced how they actually run Codex agents; four cryptographers launched the private AI chat you can audit yourself; there's a flyable universe in a browser with no login; and the final two regional events for The Pitch by Deel are coming up.

One agent per ticket

<a href="https://www.producthunt.com/products/openai/launches/symphony-8">Symphony</a> is OpenAI's open-source specification for Codex agent orchestration — it turns a Linear board into a control plane where every open ticket gets an agent running on it continuously until it's done, humans review the output, and accepted PRs land automatically.
🔥 Our Take: The interesting number isn't the 15K GitHub stars — it's the 500% increase in landed PRs OpenAI's own teams saw in the first three weeks. That's not a speedup; it's a restructuring of what the job is. If every ticket has an agent running on it until it resolves, the engineering team is no longer writing code for most tasks — they're reviewing it. Symphony is OpenAI showing, not just saying, what that looks like in practice.

Every ticket gets a Codex agent

<a href="https://www.producthunt.com/products/tinfoil-private-ai-chat/launches/tinfoil">Tinfoil</a> is a private AI chat and inference API from Jules Drean and Sacha Servan-Schreiber — both MIT PhDs who spent years studying trusted hardware and privacy cryptography before building this — plus a former Tor engineer and a Cloudflare cryptographer, running conversations inside hardware secure enclaves so that no one, including Tinfoil, can read them.
🔥 Our Take: Most "private AI" is a privacy policy. This is a different category — hardware enclaves are the same infrastructure that protects bank transactions, and the founders didn't come from AI, they came from security research. The claim isn't "trust us"; it's "here's how you verify it yourself." That's worth paying attention to if you've been self-censoring what you bring to ChatGPT.

The private AI with receipts

<a href="https://www.producthunt.com/products/astrogrid/launches/astrogrid-universe-engine">AstroGrid — Universe Engine</a> is a browser-based 3D space explorer from Velon Space that renders 119,000 catalogued stars using real NASA JPL orbital data, 14,000 deep-sky objects, and gravitational lensing on black holes — fully client-side, no installation, no signup.
🔥 Our Take: Someone built a physics-accurate flyable universe and put it in a browser tab with no server required. It's not a product for a market; it's closer to a demo that shouldn't exist yet. Open it and see how far you get before you notice you've been flying for twenty minutes.

Your browser is a spaceship now
