  • Designed for high-volume tasks (a "workhorse"), now default for consumers, enterprises, and developers.
  • Enhanced understanding of user intent and capable of interpreting multimodal content (videos, sketches, audio).
  • Slight uptick in token costs, but benchmarks indicate strong value.
• Timestamps: [02:00]–[02:33]

2. China Achieves Milestone in Semiconductor Tech

• Shenzhen scientists, largely former ASML engineers, completed a prototype of an extreme ultraviolet lithography (EUV) machine—previously a Western monopoly.
  • The machine, part of Huawei's secretive "LED Manhattan Project," is vital for advanced chipmaking.
  • Despite engineering the machine, mass chip production with EUV isn't expected before 2028–2030.
  • “These achievements stem from a six-year Huawei LED Manhattan Project to gain semiconductor independence…” (Robb Dunewood, 02:37)
• Timestamps: [02:33]–[03:00]

3. FTC Probes Instacart AI Pricing

• The U.S. Federal Trade Commission issued a civil investigative demand to Instacart over their AI-based pricing tool, Eversight.
  • Study cited possible overcharging of up to 23% for some users; average case around 7%.
  • Instacart argues increases are a result of short-term randomized tests, denies dynamic pricing tied to user data.
  • “The FTC expressed concern over Instacart's alleged pricing practices. Instacart claimed the variances were from limited, short-term and randomized tests conducted by retail partners using Eversight…” (Robb Dunewood, 03:12)

  • “YouTube's global head of music Lyor Cohen stressed that the platform believes all plays should be counted equally and hopes to resolve the issue…” (Robb Dunewood, 04:22)
• Timestamps: [04:08]–[04:29]

6. Micron Predicts Persistent RAM Shortages Due to AI

• Micron Technology foresees ongoing RAM shortages and price increases, driven by manufacturers prioritizing high bandwidth memory (HBM) for AI servers.
  • Strong Q1 2026 financials: $13.64 billion revenue, $5.2 billion net income.
  • CEO expects margins to remain high due to outstripped supply.
• Timestamps: [04:30]–[05:03]

7. OpenAI Launches ChatGPT App Directory

• App integrations announced for ChatGPT (now on iOS, Android, and web).
  • Connects with services like Booking.com, Spotify, Dropbox, Apple Music, DoorDash.
  • “These apps extend ChatGPT's functionality for tasks such as ordering groceries or summarizing documents… This move is part of OpenAI's strategy to create a more versatile ecosystem.” (Robb Dunewood, 05:11)
