The Unknown Tech that Enables AGI: Claude Mythos and NVIDIA's Next Generation
April 23, 2026
AI Summary
5 min readIn March 2024, Jensen Huang pulled a slab of metal out of his pocket on stage at NVIDIA’s GTC conference. It was the Blackwell chip, with 208 billion transistors, and the crowd treated it like the future had arrived. Nearly two years later, that chip powered Claude Mythos—the Anthropic model that found decade-old security flaws overnight, scared the federal government, and sent top banks into emergency meetings. The episode’s central argument is that AGI-level models are already here; we just haven’t powered up the GPUs that enable them. The hardware is not a supporting player—it is roughly 70% of the influence on how intelligent a model becomes.
The lag between chip announcement and model release

What you'll learn
- 1 (00:08) **Claude Mythos and the Blackwell Backend** - The hosts introduce the episode's core thesis: the Claude Mythos model, which found decade-old security flaws, was powered by NVIDIA's Blackwell chip announced in March 2024, highlighting the hardware's role in enabling AGI-like models.
- 2 (01:19) **AGI Is Here, Just Not Distributed** - The core claim: AGI-like models already exist but haven't been deployed because the GPUs enabling them haven't been powered up yet.
- 3 (02:19) **Timeline: From Blackwell Announcement to Model Release** - A detailed chronology of how NVIDIA's chip announcements translate into real-world models, showing a consistent 6-12 month delay.
- 4 (04:06) **Hopper to Blackwell: Software Efficiency Gains** - The hosts compare GPT-4 and GPT-5.4, both trained on older Hopper chips, to show how software improvements have increased hardware throughput.
- 5 (05:33) **NVIDIA's Chip Roadmap: Vera Rubin, Rubin Ultra, Feynman** - The hosts present a chart showing the projected compute multiples for future NVIDIA chips, with no software progress assumed.
- 6 (06:30) **Intelligence Per Density and Cost Declines** - The improvements are not just speed but cost efficiency: each successive chip makes training the same intelligence cheaper.
- 7 (07:57) **Projected Intelligence Multiples by Year** - A forward-looking table shows hardware-only improvements: 10-15x by 2027 (Vera Rubin), 30-50x by 2028, and 100-200x by 2029.
