Explanation of cross-entropy as a loss function in AI, including intuition, formal definition, examples, and relationship to entropy and KL divergence

Comprehensive guide to LLM fine-tuning methods including full, parameter-efficient, and preference-based approaches with modern recipes and tools like LoRA and DPO

Definition and best practices for deterministic grading in LLM evaluation using code-based rules instead of model-in-the-loop judgment.

Overview of dataset formats supported by Unsloth Studio for fine-tuning, including JSONL, Alpaca, ShareGPT, ChatML, and Reasoning formats with rules and best practices and dataset size guidelines

Overview of MoE architecture, routing, key components, variants, and trade-offs in machine learning models

Prompting technique where an AI model is guided — or learns — to reason through a problem step by step before arriving at the final answer, rather than jumping straight to the conclusion.

Extension of chain-of-thought prompting to multimodal settings where models reason step-by-step over both visual and textual information.

Explains how AI models maintain context across multiple exchanges using conversation history injection rather than internal memory.

Overview of agent harness engineering — the scaffolding, infrastructure, and tooling surrounding an AI agent, covering execution environments, tool orchestration, memory management, control flow, tracing, safety, and state persistence

Overview of diffusion models, how they reverse a gradual noising process to generate data, key variants like DDPM, DDIM, and Latent Diffusion Models, and how text-to-image conditioning works

Overview of the different types of AI prompts including system, user, few-shot, zero-shot, chain-of-thought, meta, and retrieval-augmented prompts

Overview of Elastic Looped Transformers, an adaptive compute architecture that loops a shallow transformer block multiple times to dynamically allocate compute based on input complexity

Overview of Tempo, a query-aware temporal compression framework for long-video understanding in multimodal AI, using a small VLM to filter relevant frames before passing a condensed representation to a large model

Overview of memory-augmented neural network architectures that add dynamic external memory to models, covering NTMs, RAG, Memorizing Transformers, Titans, and practical implications for building persistent AI agents

Explanation of forward pass and single pass in LLMs, how transformer computation flows from embedding to output logits, and how speculative decoding exploits transformer parallelism to reduce large-model forward passes

Explanation of speculative decoding, an inference optimization that uses a fast draft model to propose tokens verified in parallel by a large model, achieving 2–3x throughput gains with identical output quality

Explanation of what model weights are in LLMs, how they encode learned behaviour, why parameter count matters, and how systems like Ollama load them into memory

Overview of the GGUF binary format for storing and distributing LLMs locally, including quantization levels, key characteristics, and popular runtimes like llama.cpp and Ollama

Explanation of prompt bias, how prompt wording and framing skew AI outputs, common forms including leading questions and assumption bias, and practical advice for writing neutral prompts

Explanation of primacy bias in LLM selector prompts, how alphabetical candidate ordering caused over-selection of certain styles in BHQ, and fixes using deterministic non-lexicographic shuffling
