GitHub FareedKhan Dev/train LLM From scratch: A straightforward method for training your LLM, from downloading data to generating text.
A single-GPU end-to-end LLM training guide lands on GitHub—hand-written PyTorch, pretrain to chat in one repo, plus full RLHF. Vince is giddy; Ava wants to know which corner of the GPU shelf this actually runs on. Build Next shows the exact CLI to kick it off on a T4.
-
Overview: Fine tuning on Execution Traces
We keep throwing around fine-tuning on execution traces, so we finally define it from the ground up. We’re talking about training a model on the steps, not just the answer, and why that changes what it learns.
-
Overview: Sequence Modeling
We slow down and finally define sequence modeling, the idea underneath next-token prediction, language models, and a surprising amount of modern AI. We keep it grounded in one picture: covering the next word and training a model to guess what belongs there.
-
Overview: Model Generalization
We finally slow down and make model generalization click from the ground up: what it means, how you measure it, and why memorizing the training set is a dead end. We keep coming back to the same simple idea, because that’s the whole game.
-
Overview: Train Test Split
We finally slow down on train-test split, because we keep bumping into it every time we talk about whether a model actually learned something. We use the sealed-final-exam picture to make the training set, validation set, test set, overfitting, leakage, and cross-validation click without assuming ML background.
-
Overview: Supervised Fine Tuning
We finally slow down and make supervised fine-tuning click, because we keep leaning on S F T like everyone already has the whole shape of it. We build it from the apprentice-and-worked-examples picture into the actual training loop, the examples, and the trade-offs.
-
Overview: Fine Tuning
We finally do the fine-tuning episode we kept circling, and we make the core idea click: you start with a pretrained model, then adjust its weights on your own examples so it behaves the way your task actually needs. We also dig into when that helps, when it doesn’t, and why the quality of the data is the whole game.
-
Seed: Self Evolving On Policy Distillation for Agentic Reinforcement Learning
Seed tackles the credit-assignment problem in long-horizon agent reinforcement learning by turning completed trajectories into evolving natural-language hindsight skills, then distilling their effect into dense token-level training signals. Vince sees a potentially shippable training pattern for teams already running agentic RL; Ava likes the on-policy design but wants stronger evidence that self-generated skills do not amplify the model’s own blind spots.
-
Overview: Neural Network Parameters
We finally slow down and make neural network parameters click from the ground up: what they are, how training changes them, and why the final frozen numbers matter so much. We keep coming back to the same mental picture so it actually sticks, instead of just sounding like another ML buzzword.
-
Overview: Deep Learning
We finally slow down and make deep learning click: what the deep part means, how layers learn features, and why training needs data, compute, loss, backpropagation, and gradient descent all working together.
-
Overview: Loss Function
We’re finally slowing down and making loss function click: the scoreboard that tells a model how wrong it was, and the signal that lets training move in a useful direction. We also keep the usual Justy-Cody back-and-forth, because apparently even a loss function needs two friends arguing about it for forty minutes.
-
Overview: Backpropagation
We finally define backpropagation the way we probably should’ve ages ago: as the backward bookkeeping step that tells a neural network which knobs caused the miss. We also connect it to loss, gradients, and gradient descent so the whole training loop actually clicks.
-
Overview: Gradient Descent
We’re finally giving gradient descent the full couch-table treatment, because it’s hiding under half the AI stories we keep talking about. We get into the hill-climbing mental model, how loss, parameters, and backpropagation fit together, and why the whole thing is the boring engine that actually makes learning happen.
-

Stanford's TRACE system converts recurring agent failures into targeted synthetic training environments, using LoRA experts and MoE routing to close specific capability gaps without retraining the whole model.
-
Overview: Reinforcement Learning from Human Feedback
We finally define reinforcement learning from human feedback the way we keep using it: as a loop where human preferences become a learned reward signal that steers a model after its initial training. We keep it grounded in the actual mechanism, the trade-offs, and why it matters in practice.
-
Overview: Neural Network
We finally slow down on neural networks: what they are, how the little adjustable pieces learn from examples, and why this basic idea sits underneath so much of modern A I.
-

-
CausalMix: Data Mixture as Causal Inference for Language Model Training
We unpacked CausalMix, the paper that treats data‑mixing as a causal inference problem. Cooper pulls the product angle—why it matters for shipping models, and Miles dives into the DML‑based plumbing and the trade‑offs. We talk about how it tackles shifting data pools, the CATE forest, and why the authors think it can generalize to larger models. A touch of banter and a light‑hearted sign‑off close the episode.
-
Reinforcement Learning with Metacognitive Feedback Elicits Faithful Uncertainty Expression in LLMs
Jessica and Cathy dig into RL with Metacognitive Feedback (RLMF): a post-training loop that rewards models not just for correct answers, but for accurately judging how well they did—improving both task performance and the faithfulness of uncertainty expressions. They explain the mechanism (metacognitive data selection and metacognitive advantage scaling), discuss trade-offs, and debate whether this is still research-only or actually shippable.
-
HarnessX rewrites AI scaffolding mid task | VentureBeat
Xiaomi's HarnessX treats AI agent scaffolding as a first-class, modular object that can evolve mid-task without changing the underlying model. A trace-driven RL engine (AEGIS) automatically rewrites harness components—prompts, tool integrations, memory, control flow—while safeguarding against reward hacking and catastrophic forgetting. When paired with model fine-tuning on execution data (cross-harness GRPO), smaller models like Qwen3.5-9B see +44% gains on embodied planning, suggesting harness engineering, not just model scale, is the real bottleneck for enterprise agents.
-
Qwen AgentWorld: Language World Models for General Agents
Justy and Cody dig into Qwen-AgentWorld, a new language world model that simulates seven agent environments. Cody breaks down the three-stage training pipeline (CPT, SFT, RL) and explains why a world model is the missing piece in agent development. Justy connects it to product reality: who ships this, what it actually unlocks, and whether it’s ready beyond the paper. They finish with cautious excitement and a quick Build Next check-in.
-
Introducing OpenRL: A self Hosted post training API for fine tuning LLMs | Google Open Source Blog
Justy and Cody discuss Google’s OpenRL, a self-hosted post-training API that tries to separate RL research loops from the Kubernetes and GPU infrastructure underneath them.
-
Agentic Rl
Cameron Wolfe's 'Agentic RL' argues that training LLMs for agentic work requires shifting from single-turn reasoning to multi-turn trajectory optimization, where the harness (tools, environment, memory) becomes part of the RL loop itself. The central claim is that standard post-training methods fail on long-horizon tasks because they don't account for environment state changes across steps, necessitating new rollout infrastructures and stability techniques like PPO over GRPO for variable-length traces.
-
VibeThinker 3B: Exploring the Frontier of Verifiable Reasoning in Small Language Models
Justy and Cody get into VibeThinker-3B, a three-billion-parameter reasoning model that posts unusually strong math and coding results by treating verifiable reasoning as something you can compress into a small core.

Justy and Cody discuss a paper proposing S two L P O, a small-to-large rollout strategy for G R P O that uses smaller same-family models as structured explorers for reasoning model training.
-
Skip a Layer or Loop It? Learning Program of Layers in LLMs
Justy and Cody dig into PoLar, a paper arguing that a pretrained LLM does not need to run its layers in one fixed order for every input. They talk through the main idea of treating layers like reusable functions that can be skipped or repeated, how the authors used Monte Carlo Tree Search to discover better layer programs, and why a lightweight predictor makes the idea more practical. The conversation centers on what problem this solves, why dynamic depth methods have been too narrow, and whether this feels like a research curiosity or an actual path to deployment.
-
A $1,500 foundation model that rivals larger LLMs
Justy and Cody unpack Sapient's claim that HRM-Text, a one-billion-parameter foundation model trained from scratch for about fifteen hundred dollars, can compete with larger open models by changing the architecture and training objective.
-
LatentSkill: From In Context Textual Skills to In Weight Latent Skills for LLM Agents
Exploring LatentSkill, a framework that turns textual agent skills into weight-space LoRA adapters, cutting prompt overhead while keeping modularity and composability. Cody digs into the hypernetwork design and trade-offs; Justy asks what shipping this looks like and who’d actually adopt it.
-
Automate Writing Your LLM Prompts | Towards Data Science
Cody and Justy dissect the argument that manual prompt engineering is obsolete in production, focusing on the DSPy framework's claim to automate prompt optimization. Cody challenges the 'black box' nature of auto-generated prompts and the computational cost, while Justy argues this shifts the developer role from 'prompt writer' to 'system architect,' solving the fragility of hard-coded strings. They land on a nuanced verdict: DSPy is powerful for stable, high-volume tasks but overkill for exploratory prototyping.
-
Rethinking Continual Experience Internalization for Self Evolving LLM Agents
Jingwen Chen et al. diagnose why iterative experience internalization fails in LLMs and prescribe a three-part fix—principle-level granularity, step-wise injection, off-policy context-distillation—that turns capability collapse into compounding improvement.
-
MemTrain: Self Supervised Context Memory Training
Self-supervised framework MemTrain improves LLM context memory by training on unlabeled Wikipedia with coupled proxy tasks—masked reconstruction and memory recall—using GRPO. Achieves up to 17.67-point gains on long-horizon reasoning without task-specific labels.
-
SkillAdaptor: Self Adapting Skills for LLM Agents from Trajectories
Justy and Cody discuss SkillAdaptor, a new training-free framework that pinpoints the exact step where an LLM agent fails, rather than blaming the whole session. They debate whether this 'step-level' precision makes it shippable for production agents today or just a clever research trick.
-

Justy and Cody unpack LongTraceRL, a paper that trains long-context reasoning models using realistic search-agent distractors and entity-level rubric rewards, with a short look at what would make it shippable.
-
MetaAgent X : Breaking the Ceiling of Automatic Multi Agent Systems via End to End Reinforcement Learning
Justy and Cody discuss MetaAgent-X, a new paper proposing end-to-end reinforcement learning for multi-agent systems. They break down how it solves the 'frozen-executor ceiling' by jointly optimizing both the agent that designs the workflow and the agents that execute it. Cody explains the hierarchical rollout mechanism and stagewise co-evolution, while Justy explores what this means for production pipelines that currently rely on static prompts. They touch on the 21.7% performance gains, the reality of training stability, and whether this moves us from 'prompt engineering' to actual 'system engineering.'
-
Many Shot CoT ICL: Making In Context Learning Truly Learn
Justy and Cody dig into a paper arguing that long-context chain-of-thought prompting behaves less like stuffing a prompt with relevant examples and more like teaching the model during inference. They unpack why many-shot tricks from classification break on reasoning, why semantic retrieval stops helping, and how the paper’s Curvilinear Demonstration Selection tries to order examples like a smooth mini-curriculum.
-
Teaching Claude why
Cody and Justy dig into Anthropic's 'Teaching Claude Why' research — a post-training alignment paper showing that teaching an AI model ethical reasoning generalizes far better than just training it on correct behaviors. Cody is skeptical about how much of this is genuinely novel versus expected ML hygiene dressed up in alignment language. Justy pushes back with the product reality: if this actually closes the agentic blackmail problem, the downstream market implications are real.
-
HeavySkill: Heavy Thinking as the Inner Skill in Agentic Harness
Justy and Cody dig into HeavySkill, a paper arguing that a lot of so-called agent harness magic is really a simpler inner pattern: generate multiple reasoning paths in parallel, then run a separate deliberation pass that compares and summarizes them. They unpack the memory-cache trick, why it can beat plain Best-of-N, where the gains seem to come from, and what this means for builders deciding between brittle orchestration and something more shippable.
-
From Context to Skills: Can Language Models Learn from Context Skillfully?
Cody and Justy dig into Ctx2Skill, a self-evolving framework that turns long, dense context into reusable natural-language skills for language models. They talk through the core loop, the role of Challenger, Reasoner, Judge, and the replay trick that keeps the system from drifting into weird overfit territory, then land on what it means for product teams trying to ship context-heavy workflows.
-
Alibaba's HDPO cuts AI agent tool overuse from 98% to 2%
Justy and Cody dig into Alibaba's HDPO and Metis, a training setup that teaches AI agents to stop calling tools by default. Cody likes the core idea because it separates accuracy from efficiency during reinforcement learning, but he questions how portable the benchmark win is. Justy pushes on why this matters for real products right now: users feel latency, teams feel API bills, and nobody wants an agent that opens a toolbox for a task it already knows how to do.
-
Build a Reinforcement Learning Powered Agent That Learns to Retrieve Relevant Long Term Memories
Cody and Justy dig into a tutorial that trains an RL agent — using PPO via Stable-Baselines3 — to retrieve long-term memories more accurately than plain cosine similarity search. They debate whether the added complexity is justified, who actually needs this, and what it would take to move from a synthetic demo to something production-worthy.
-
LeWorldModel: Stable End to End Joint Embedding Predictive Architecture from Pixels
Justy and Cody dig into LeWorldModel, a pixel-to-latent world model that tries to make JEPA training boring in the best way. The paper’s claim is simple but pretty important: you can jointly train the encoder and dynamics model from raw pixels without EMA tricks, stop-gradient, pretraining, rewards, or reconstruction, and still avoid collapse. They unpack the Gaussian latent regularizer, the autoregressive next-embedding prediction setup, and why a 15M-parameter model that runs on one GPU could matter more for builders than a flashier giant model.
-
6 Things I Learned Building LLMs From Scratch That No Tutorial Teaches You | Towards Data Science
Justy and Cody dig into what actually changes when you stop calling an LLM API and start building pieces yourself: why fine-tuning tricks like RsLoRA matter, why RoPE won, where weight tying still makes sense, why Pre-LN became the default, and how KV cache buys speed by spending memory.
-
LongAct: Harnessing Intrinsic Activation Patterns for Long Context Reinforcement Learning
Justy and Cody dig into LongAct, a paper about making long-context RL work better by updating only the attention weights tied to unusually large query and key activations. They unpack why that matters for long docs, agents, and multi-step reasoning, how the saliency-guided sparse updates map activation outliers back to specific weight rows, and why the reported gains across LongBench v2, RULER, and multiple RL algorithms suggest this could be more than a lab curiosity.
-

They built PRISM, a self-bootstrapping system that routes queries to personas only when they actually help, using no external data.
-
Reasoning as Compression: Unifying Budget Forcing via the Conditional Information Bottleneck
Chain-of-Thought prompting makes LLMs more accurate but expensive. This research reframes efficient reasoning as a compression problem, introducing a conditional information bottleneck approach that preserves essential reasoning while cutting cognitive bloat. Instead of naive length penalties, they use semantic priors based on token surprisal to compress reasoning traces intelligently.
