OpenAI Buys Ona to Power Long-Running Codex Tasks

June 11 deal: OpenAI acquires Ona, the Kiel, Germany cloud-platform startup that gives AI agents secure, pre-configured execution environments with tools, systems and context preloaded.
Ona's team folds into the Codex effort, which now serves 5M weekly active users — up from 3M in April; Ona has supported 2M developers with reproducible cloud workspaces.
Strategic angle: Codex gets the runtime to take on multi-step, long-horizon work — Bloomberg frames it as OpenAI grabbing the compute layer for agents before Anthropic does.
Terms undisclosed; transaction subject to standard closing. Top HN comment: 'compute layer ownership is going to be critical going forward.'

SPCX starts trading June 12 after pricing Thursday at a fixed $135/share, raising $75B and blowing past Saudi Aramco's $29.4B 2019 record by 2.5×.
Implied valuation ~$1.77T, above Tesla and the seventh-largest US company by market cap; 555.6M Class A shares hit the float.
Includes xAI, absorbed by SpaceX in February at a $1.25T combined value — public investors now own the Grok/Colossus compute stack alongside Starlink.
$17.5B of legacy debt from X and xAI rolls into the SPCX balance sheet; S-1 launched with blank price fields and skipped the traditional book-build range.

June 11 launch: built-in `/marketplace` catalog in Grok Build CLI, with browse-install-update flow that never leaves the terminal.
Launch plugins: MongoDB (data + query tuning), Vercel (deploys), Sentry (stack-trace debugging), Chrome DevTools (live browser control), Cloudflare (Workers/DO), and Superpowers (agentic workflows).
A plugin bundles skills, slash commands, agents, hooks, MCP servers and LSPs in one installable package — mirrors the Claude Code / Codex skill pattern.
Open catalog at `xai-org/plugin-marketplace` on GitHub; pull requests welcome. Caveat: still gated behind the $299/mo SuperGrok Heavy plan.

June 11 update: average review drops from ~5 minutes to ~90 seconds; 90% of runs finish under three minutes.
Finds 10% more bugs per review (0.62 vs 0.56) at ~22% lower cost — gains attributed to Composer 2.5 training progress.
New `/review`, `/review-bugbot`, `/review-security` commands run pre-push; syncs with the GitHub/GitLab Bugbot so the same diff isn't re-reviewed.
Smart PR re-reviews now focus only on what's new since the last pass. Available in Cursor 3.7+ and at cursor.com/agents; CLI support coming.

Audio model built on Gemini 3 Pro: streaming speech-to-speech translation in 70+ languages with auto source-language detection.
Preserves speaker intonation, pacing and pitch; translates mid-sentence instead of waiting for the speaker to finish — the gap that killed earlier real-time tools.
Rollout: public preview via Gemini Live API and AI Studio for developers; enterprise private preview in Google Meet; consumer rollout in Google Translate on Android and iOS.
Launch partners Agora, LiveKit, Pipecat, Software Mansion and Vision Agents flag latency and pacing as a new bar for live multimedia.
