dabbycastro.com is live. It’s where I put everything I’ve worked on in one place. - CramIt, an AI study platform I started on pre-ChatGPT completion models that now has 2,200+ users. - Ace Signal, a geospatial intelligence app that scores all 42,048 Philippine barangays for ISP deployment using NASA, NTC, and Copernicus data. - The Future Frontiers AI Ideathon I organized and chaired at 17, covered by BusinessWorld. - Code Wraith, a combat platformer I made in two weeks. - and more. If any of that sounds interesting, the full write-ups are on the site #buildinpublic

Andrej Karpathy@karpathy·
Judging by my tl there is a growing gap in understanding of AI capability. The first issue I think is around recency and tier of use. I think a lot of people tried the free tier of ChatGPT somewhere last year and allowed it to inform their views on AI a little too much. This is a group of reactions laughing at various quirks of the models, hallucinations, etc. Yes I also saw the viral videos of OpenAI's Advanced Voice mode fumbling simple queries like "should I drive or walk to the carwash". The thing is that these free and old/deprecated models don't reflect the capability in the latest round of state of the art agentic models of this year, especially OpenAI Codex and Claude Code. But that brings me to the second issue. Even if people paid $200/month to use the state of the art models, a lot of the capabilities are relatively "peaky" in highly technical areas. Typical queries around search, writing, advice, etc. are *not* the domain that has made the most noticeable and dramatic strides in capability. Partly, this is due to the technical details of reinforcement learning and its use of verifiable rewards. But partly, it's also because these use cases are not sufficiently prioritized by the companies in their hillclimbing because they don't lead to as much $$$ value. The goldmines are elsewhere, and the focus comes along. So that brings me to the second group of people, who *both* 1) pay for and use the state of the art frontier agentic models (OpenAI Codex / Claude Code) and 2) do so professionally in technical domains like programming, math and research. This group of people is subject to the highest amount of "AI Psychosis" because the recent improvements in these domains as of this year have been nothing short of staggering. When you hand a computer terminal to one of these models, you can now watch them melt programming problems that you'd normally expect to take days/weeks of work. It's this second group of people that assigns a much greater gravity to the capabilities, their slope, and various cyber-related repercussions. TLDR the people in these two groups are speaking past each other. It really is simultaneously the case that OpenAI's free and I think slightly orphaned (?) "Advanced Voice Mode" will fumble the dumbest questions in your Instagram's reels and *at the same time*, OpenAI's highest-tier and paid Codex model will go off for 1 hour to coherently restructure an entire code base, or find and exploit vulnerabilities in computer systems. This part really works and has made dramatic strides because 2 properties: 1) these domains offer explicit reward functions that are verifiable meaning they are easily amenable to reinforcement learning training (e.g. unit tests passed yes or no, in contrast to writing, which is much harder to explicitly judge), but also 2) they are a lot more valuable in b2b settings, meaning that the biggest fraction of the team is focused on improving them. So here we are.

The degree to which you are awed by AI is perfectly correlated with how much you use AI to code.

Project Hail Mary Updates
Project Hail Mary Updates@HailMaryLogs·
We’re getting a game set in the Project Hail Mary universe, with direct involvement from Andy Weir himself! Project Hail Mary: Journey Among the Stars is a mixed reality and VR experience where we step into the role of Ryland Grace, diagnose failing systems, and work alongside Rocky to keep humanity’s last hope alive. It’s a completely new story that we’ll be able to experience on platforms like Meta Quest 3 and Pico 4. Amazing to see the Project Hail Mary universe expanding beyond the book and the movie.

Earthset. The Artemis II crew captured this view of an Earthset on April 6, 2026, as they flew around the Moon. The image is reminiscent of the iconic Earthrise image taken by astronaut Bill Anders 58 years earlier as the Apollo 8 crew flew around the Moon.

Make new friends, but keep the old. A new photo captures the Moon's near side on the right (the side we see from Earth, identifiable by its dark splotches) and its far side on the left. The Artemis II crew are the first to see the far side with human eyes.

Project Hail Mary Updates
Project Hail Mary Updates@HailMaryLogs·
A small spoiler, so consider this your heads-up. In one of the final scenes, Eva Stratt has a subtle tattoo on her neck: a crossed-out "V". It’s easy to miss, but it carries a lot of meaning. The "V" comes from the French word 'via' ("life"), and the strike through it points to a life that was taken or lost. The detail comes from Andy Weir's idea of where Stratt's story goes after the Hail Mary mission launches. In the book, she predicts her own fate with unsettling clarity: once her role is fulfilled, governments turn on her, stripping of power and ultimately imprisoning in a French prison for the very ruthlessness that made the mission possible. The film quietly extends that arc. The last scene suggests she made it out, and somehow found her way back to the work of saving humanity. All of this was confirmed by the directors in an interview.

A fan created a visualization of how the spin drive works in Project Hail Mary. It’s a beautifully simple cycle. First, a small light tuned to the Petrova frequency attracts Astrophage from the fuel line, coating one side of a transparent triangular mechanism. Then the triangle rotates, exposing that surface to space. The light intensifies and the Astrophage releases its energy, pushing against the surface and generating thrust. Finally, the triangle rotates back inside, the spent Astrophage is scraped off, and the cycle begins again. In the book, the Hail Mary runs 1009 of these in parallel.

Lock in, we’re Moonbound. Artemis II astronauts are more than halfway to their destination, and preparations for lunar flyby are underway. During their trip around the far side of the Moon, they will capture imagery to share with scientists (and you, too!).

NASA pilot Victor Glover CLAPS back after being asked what it means to be the first black man to visit the moon: “It’s the story of humanity, not black history, not women’s history, but that it becomes human history.” “I also HOPE we are pushing the other direction that one day we don’t have to talk about these first. That one day, this is just—and listen to this—that this is the human history.”
