Jeremy Howard’s case for accessible deep learning leads to a harder question: how can a language model learn a specialization while retaining its broader abilities?
The Four AI Wars: From Frontier Models to Deployable Systems — Part 1 of 3
Part 1 of this 2024 Latent Space recap follows the path from AI investment to useful systems: stronger models, synthetic data, cheaper inference, local execution and multimodal applications.
The Four AI Wars: From GPU Wealth to Useful Work — Part 1 of 3
Part 1 of 3 follows an early-2024 debate over compute, data, model competition and reliable agents, ending with how faster inference could change the applications worth building.
The Four Wars of the AI Stack
Latent Space’s December 2023 recap follows the competition over training data, inference economics, multimodal products, and application tooling—then turns to coding agents and personal-context hardware.
The GPU Is Only as Useful as the System Feeding It
AI economics, inference bandwidth and chip design in Latent Space’s November 2023 conversation with Dylan Patel—ending with the question of whether training can escape a single data center.
The Lab as a Learning System — Part 2 of 3
Part 2 of 3 follows Lila Sciences from improving drug-development odds to connecting instruments, shortening experimental cycles, and training scientific models—then asks where simulation still falls short.
The Point of LangChain: Context, Control, and Debugging
From a bot over Notion and Slack to SQL agents and application traces, LangChain addresses the work surrounding a model call.
The RLVR Revolution: From Checking Answers to Training Agents
Tulu’s practical post-training recipe leads to harder questions: how models learn to use tools, choose plans, recognize success, and remain useful as rewards become more complex.
The Self-Driving Lab: Turning Alloy Predictions into Experimental Knowledge
Radical AI connects hypothesis generation, robotic experiments and scientific judgment. The next challenge is carrying that feedback loop into manufacturing.
The Ultimate Guide to Prompting: From Examples to Engineered Systems
How examples, reasoning, automated optimization, and adversarial testing shape the behavior of language models—and where prompting becomes systems engineering.
The Utility of Interpretability — Part 1 of 3
Circuit tracing turns a model’s next-token prediction into a testable account of intermediate computation. Part 1 follows the tools, their limits, and the case for understanding models before relying on them.
The Utility of Interpretability, Part 2 of 3: From Copying to Hidden Plans
Circuit tracing connects internal features to model outputs, then tests those connections by changing them. Part 2 explores shared concepts, advance planning and misleading explanations before turning to the tools’ limits and the trade-offs of publishing them.
The Utility of Interpretability, Part 3 of 3: From Experiments to Explanations
Part 3 of 3 examines the work behind clear interpretability papers, the infrastructure that speeds up subsequent investigations, and the questions newcomers can pursue.
The Vector Database Category Gives Way to Search
Vector search remains useful. The question is whether it needs a separate database—and how retrieval should fit the application’s data, quality requirements, and workload.
Thinking Longer Is Only Part of the Problem
From Cicero’s unusual moves to coding agents and multi-agent learning: what extra reasoning buys, and why objectives, experience and elapsed time still matter.
TinyStories: Making Language-Model Reasoning Small Enough to Study
Synthetic children’s stories make coherence, elementary reasoning and model internals accessible to small experiments. Which lessons transfer to larger models remains an open question.
tldraw: How a whiteboard became an AI input device
Good-looking arrows, digital ink, and reusable canvas interactions led to a workspace for expressing intent—and revising what a model produces.
Together AI: Making Open Models Practical Across the Stack
Together connects data selection, model architecture and GPU systems to lower the cost of building and serving models. Its goal of 5,000 tokens per second reaches beyond faster chat.
Training a 70B Model Means Debugging the Whole Stack
The engineering behind reliable clusters, predictable training runs, and evaluations that measure useful coding capabilities.
Training a Million-Token Context Window Is Only the Beginning
Gradient’s context-extension work combines positional scaling, distributed training and carefully constructed data. The harder test is whether a model can use the extra information.
Training IDEFICS: the engineering behind an open multimodal model
How Hugging Face’s M4 team connected pretrained models, built interleaved web data, debugged unstable attention and planned a smaller successor.
Training LLMs: From Compute Estimates to Working Clusters
How training budgets, numerical precision, memory and communication shape the practical work of running large language models.
Vibe Physics: When Deriving an Answer Becomes Faster Than Checking It
AI-assisted scattering calculations show how a well-posed question, a simplifying assumption, and expert verification can turn an unwieldy expression into a research result.
Video as Tokens, Motion as Features — ICML 2024, Part 2 of 6
Part 2 of 6: VideoPoet turns video generation into sequence modeling; Tali Dekel explores controllable editing through neural atlases and motion features; Sander Dieleman begins a geometric introduction to diffusion.
What Can a Language Model’s Numbers Tell Us?
Recovering text from embeddings, aligning model representations, and measuring memorization reveal the gap between information stored and information we can use.
What ClusterMAX Measures When It Ranks GPU Clouds
A practical guide to managed clusters, reliability and security from SemiAnalysis’s ClusterMAX 3.0 discussion.
What It Took to Replace a Conference SaaS Workflow With AI Agents
A speaker-management contest tested AI-built software against the details of real event operations—and exposed the gap between a demo, an evaluation and an owned service.
What Makes a Model Improvement Worth Using? — Part 2 of 3
Part 2 follows the choices behind useful model improvements: architecture, evaluation, training budgets, context, serving costs—and the research habits that sustain them.
What Makes a Thousand-Layer RL Network Trainable?
Goal-reaching agents benefit from depth when the learning objective, architecture, and supply of experience scale together.
What Makes an AI Application Worth Building?
Shrinking model advantages put more weight on product design, integration and execution. The Unsupervised Learning × Latent Space crossover explores where that work creates value—and where technical limits still matter.
