Week of 22 April 2026
Notes on an April interview and a cybersecurity research announcement. This is a dated reading record.
Jensen Huang on the wider system
In his interview with Dwarkesh Patel, Huang argued that Nvidia's position depends on software, libraries, and integrated systems as well as chips. Read it as the company's case for its approach, with Patel questioning the assumptions behind it.
Mythos Preview and vulnerability discovery
Anthropic's 7 April research report describes Mythos Preview finding and exploiting software vulnerabilities, including a previously undiscovered 27-year-old OpenBSD bug. These are the developer's reported results. The article explains its testing and coordinated disclosure process; it does not establish a comparison with India's capabilities.
Older chips, more energy
Huang argued that access to energy could help compensate for less advanced manufacturing. That is a claim about the wider computing system. It should not be shortened into a technical assertion that any 7nm chip is equivalent to an Nvidia Hopper accelerator.
Power and construction
The interview also places power and data-centre construction alongside chip supply. The useful question for a project is which of those constraints applies at its proposed site. A general industry argument cannot answer that local question.
Post-training
Huang discusses reinforcement learning and the work done after initial model training. For an introduction to the different methods, see the post-training explainer. Its diagrams distinguish learning from examples, preferences, and reward signals.
