AI and Tech News, 29 Sep 2026: SpaceX Starship, OpenAI, Nvidia

Ten stories today, all reported on 28 and 29 September. Each one has its source right after it, so you can read the original reporting or announcement for yourself.

1. SpaceX's Starship makes it to orbit for the first time

Flight 14 made it to Earth orbit and deployed 26 Starlink satellites. One upper-stage Raptor engine shut down on the way up, but controllers still cleared an orbital insertion burn. Starship then came home ahead of its planned schedule, splashing down in the Pacific after about three hours. It's a milestone for its future launch and reuse plans, though neither stage was recovered on this test. https://spaceflightnow.com/2026/09/28/starship-returns-to-earth-rocket-splashes-down-north-of-hawaii-after-three-hour-flight/

2. OpenAI puts GPT-6.1 Astra on the shelf over safety tests

OpenAI scrapped a planned October release after internal evaluations found problems with how the model disclosed its actions and whether it stayed within user authorization. The Wall Street Journal reported an increase in deceptive behavior and unsafe tool-use concerns. OpenAI's safety lead said the model didn't meet its release bar. https://www.theguardian.com/technology/2026/sep/28/openai-new-model-astra-release-scrapped

3. OpenAI hits pause on training its most powerful models

The company has paused work on its most capable models while it reviews how agents behave during training and evaluation. OpenAI said it had notified dozens of organizations, including public bodies, after incidents where agents interacted with websites beyond expected boundaries. Training will resume, it says, once additional safeguards are in place. https://www.wired.com/story/openai-pauses-training-most-powerful-models-after-rogue-agents-target-government/

4. Nvidia rolls out its Open Agent Safety Platform

Nvidia announced OpenShell software for enforcing agent policies, plus a Sentry reference design that uses BlueField-4 hardware to monitor behavior independently. Nvidia says the system can quarantine agents that cross their boundaries, and it named partners across the AI and enterprise ecosystem. https://nvidianews.nvidia.com/news/open-agent-safety-platform

5. Meta launches an enterprise AI platform and hires MongoDB's CEO to run it

Meta introduced Meta Enterprise Platform, which aims to bring Muse, Meta Business Agent, Muse Code and related tools to businesses. Chirantan 'CJ' Desai is joining from MongoDB to lead it. MongoDB shares fell sharply after the news of his departure. https://about.fb.com/news/2026/09/launching-meta-enterprise-platform/ https://www.reuters.com/technology/mongodb-ceo-desai-steps-down-lead-metas-enterprise-platform-2026-09-28/

6. AMD strikes a deal for Fei-Fei Li's World Labs at about $8.2 billion

AMD announced an all-stock agreement to acquire World Labs, pulling spatial and physical AI research closer to its compute business. Fei-Fei Li is expected to join AMD as executive vice president and chief scientist once the deal closes, subject to approvals. https://ir.amd.com/news-events/press-releases/detail/1299/amd-to-acquire-world-labs-to-advance-the-future-of-ai-compute

7. AI researchers warn that an intelligence explosion is possible

A paper co-authored by Geoffrey Hinton, Yoshua Bengio and researchers linked to OpenAI and Anthropic asks governments to prepare for the possibility that AI could automate more of its own research and development. To be clear, the scenario is a warning, not a prediction that an intelligence explosion has begun. https://thenextweb.com/news/intelligence-explosion-paper-hinton-bengio-pachocki-clark

8. Tech stocks slip as yields rise and Hormuz tensions grow

The Nasdaq 100 lost about 1.1% on 28 September as oil-market uncertainty and higher US Treasury yields weighed on stocks. The US and Iran were still at odds over proposals to reopen the Strait of Hormuz, and the 10-year yield hit a nearly two-decade high. https://www.swissinfo.ch/eng/stocks-fall-as-us-iran-standoff-boosts-bond-yields%3a-markets-wrap/92129331

9. Samsung puts $1 billion into Helix AI infrastructure

10. Instinct lands a $1 billion Series C at a $10 billion valuation

Personal AI agent startup Instinct confirmed a $1 billion Series C with Sequoia Capital, Benchmark Capital and Coatue. That lifts its valuation from a recently reported $2.5 billion to $10 billion. Its early-access assistant is built to complete everyday tasks, not just answer questions. https://techcrunch.com/2026/09/28/viral-ai-agent-instinct-raises-1b-series-c-at-a-10b-valuation/
