FLOPS originally denoted floating point operations per second as a system performance rate, exemplified by the SPARCstation 2's 4.2 MFLOPS. Contemporary usage extends it to absolute floating point operations for algorithms or layers, such as "8 GFLOPS" for a specific layer. This shift reflects a transition from throughput metrics to computational cost quantification in modern contexts.
Carmack highlights the durability of physical books, noting 1959 paperbacks remain readable after decades and archival editions could last centuries, while his Kindles and e-readers failed entirely. He contrasts this with ancient Sumerian tablets enduring 4000 years versus lost software from 50 years ago. This underscores digital storage's fragility, prompting support for preservation efforts like the Internet Archive.
John Carmack discloses owning an underground, blast-proof reading den or library. He explicitly denies any automated resin entombment feature. This reveals a unique personal infrastructure for secure, long-term knowledge preservation.
What order of magnitude are we talking about? How much for text vs images?
John Carmack notes that while precise regurgitation from LLMs is discouraged, their training process can achieve near-lossless compression of vast datasets like the Internet Archive. Unlike the Hutter Prize's bit-accurate compression limited to 1GB, petabyte-scale compression involves different trade-offs. This becomes particularly compelling when exact bit-for-bit accuracy is not required.
John Carmack expresses conditional interest in contributing to AI hardware development. He would likely participate if presented with a robust, well-defined plan. This stance reflects his selective engagement with high-potential technical projects.
A three-species model demonstrates that four-year oscillations in Fraser River sockeye salmon spawning numbers arise as a stable dynamical attractor from strong resonance near a Neimark-Sacker bifurcation. This mechanism accounts for the persistence of cycles matching the fish's generation time, accurately reproduces the empirical abundance sequence within one period, and explains why oscillations occur primarily in sockeye from large oligotrophic lakes and not in species with longer generation times. Prior explanations like stochasticity, depensatory fishing, or genetics are deemed unconvincing.
John Carmack proposes that many evaluation and judging tasks, including literary awards and employee performance reviews, could be significantly improved by utilizing aggregated partial orderings and pairwise comparisons. He suggests an ELO ranking system, similar to those used in chess, to facilitate more efficient and robust assessments, particularly when comprehensive review of all items is impractical.
John Carmack is funding the donation of science fiction book sets to libraries through the LFS Prometheus Awards Collection. This initiative expands access to notable works within the genre, as evidenced by his repeated orders for book batches to fulfill demand.
John Carmack suggests that GPU power draw, obtainable from tools like nvidia-smi, serves as a superior indicator of true GPU utilization compared to traditional metrics like job scheduling or "GPU busy" states. He proposes visualizing this data as heatmaps across data centers to identify inefficiencies. Carmack speculates that while inference and frontier training in major labs are highly efficient, significant GPU capacity might be underutilized due to scheduling issues and suboptimal research code.
Ablative heat shields, historically problematic for the X-15 program due to maintenance demands, are being re-evaluated in the context of modern spaceflight. While Starship’s rapid turnaround goals generally preclude ablatives, their potential for daily flight, given technological advancements, warrants consideration. This suggests a potential trade-off between maintenance intensity and reusability frequency for specific use cases.
Initial efforts to enhance value function generalization using SIGReg on prefinal activations and pre-trained LeWM have not yielded positive results. Both approaches, while aiming to induce independent Gaussian distributions or improve estimation, have demonstrably hurt generalization or resulted in worse value function estimation in early tests. Further investigation is needed as these techniques have not yet provided a performance advantage.

LeWorldModel applies the LeJEPA framework to world models, demonstrating stable end-to-end joint-embedding predictive architecture from pixels. It utilizes a ViT-Tiny vision transformer for latent generation and a ViT-S backbone for prediction. The approach demonstrates effective planning at test time using the Cross-Entropy Method and shows that latent spaces capture physically meaningful quantities, offering an alternative to traditional policy-based learning in imagination.
Elon Musk exhibits a unique combination of profound technical capability, often associated with traits on the autism spectrum, and a genuine enjoyment of collaborative work. This contrasts with a prevalent pattern where highly skilled technical individuals tend towards solitude, which can hinder their overall impact. His conscientiousness further amplifies his ability to execute and build, distinguishing him from others who might share similar cognitive profiles but lack the drive or social inclination.

John Carmack acknowledges Palmer Luckey's superior ability to delegate, contrasting it with his own limitations in this area. This suggests Luckey possesses a crucial leadership quality that Carmack believes he lacks, particularly in brand stewardship. The statement offers insight into the self-awareness of a prominent figure in the tech industry regarding their operational strengths and weaknesses.
John Carmack, a prominent figure in the tech industry, expresses a desire for a shift in the editorial stance of leading technology publications like WIRED and MIT Technology Review. He advocates for a 'Technological Triumphalism' perspective, suggesting a more optimistic and celebratory tone regarding technological advancements. This implies a critique of current tech media for potentially lacking sufficient enthusiasm for innovation.
Bluetooth audio streaming introduces significant quality degradation due to multiple stages of lossy compression and decompression. Audio is initially stream-compressed with Vorbis or AAC, then decoded, and subsequently re-compressed with SBC or AAC for Bluetooth transmission. This multi-layered compression process, highlighted by John Carmack, suggests an inefficient system architecture ripe for optimization breakthroughs.
Traditional corporate advisory boards often serve as superficial "vibe checks" rather than providing substantive guidance. This model is inefficient as it primarily involves presentations and general discussions without directly influencing company decisions. A more effective approach involves engaging advisors on an ad-hoc basis for specific, contentious issues, leveraging their expertise as unbiased external consultants rather than as a standing board.
John Carmack, a prominent figure in open-source, views AI training on open-source code as an amplification of its inherent value, aligning with his original intent of open-source as a "gift to the world." He acknowledges the overlap between open-source and anti-AI sentiments but struggles to reconcile them given his perspective on AI's ability to magnify the utility of open-source contributions.
John Carmack critiques the current platform subsidy and 30% revenue share model, identifying it as inefficient due to "wasteful churn." He advocates for Epic's tiered revenue model, where the first $1M in annual revenue is exempt from platform fees, as a cleaner solution that directly rewards increased economic activity. Carmack suggests a "negative rate 'earned income tax credit'" for initial revenue as a strong incentive, provided exploitation by self-purchase can be prevented.
John Carmack criticizes the "Deep learning and Ethics" chapter in Prince's "Understanding Deep Learning" for its superficial treatment of bias. He highlights the distinction between "illegitimate" factors (societal choices) and "irrelevant" factors (data-driven priors), arguing that the book conflates them. Carmack proposes an alternative approach to exploring bias in ML by swapping neutral feature labels with socially charged ones to analyze generalization credibility.
John Carmack's Keen Technologies is pursuing AGI through reinforcement learning on suites of Atari games, explicitly rejecting LLMs as a sufficient path to general intelligence. His core thesis is that fundamental problems — sequential multitask learning, transfer learning, sparse rewards, and continuous forgetting — remain scientifically unsolved, and that standard RL benchmarks mask this by ignoring real-world constraints like latency and turn-based assumptions. His physical Atari robot demo exposed that state-of-the-art agents like BBF collapse under even modest added latency, and that reward extraction from raw pixels (score reading) remains a surprisingly hard systems problem. He is pushing for a new community benchmark that sequences agents through multiple Atari games and tests for genuine transfer, rather than single-game mastery.
