All videos (44)

• FreeVideo 16:34What Claude is and where you can use itAnthropic, the basic idea of an LLM, Claude's key strengths, and all the entry points (apps, Claude Code, API, cloud) that build the same Messages API request.+
• Video 26:50How the request and context window are builtThe API is stateless, so the full context is sent every time; the tools, system, messages order; tokens and the context window.+
• Video 36:31Gateway, model and response: a request's journeyThe request passes the gateway, then the model (tokenizer, transformer, thinking, generation), and the response returns as JSON or an SSE stream.+
• Video 45:29The tool loop and output to the userThe model only writes tool_use and someone else runs the tool, looping until end_turn; then the forms the answer can take for the user.+
• Video 56:13Long conversations and context managementCompaction, context editing and mid-conversation system messages when context fills up, plus an overview of the Safety and Cost rails.+
• Video 65:49Inside the model: how a token is producedA zoom into stage 4: tokenizer, embeddings, attention, probabilities and sampling, with one worked example question.+
• Video 76:59How the model is trained, and why it has limitationsPretraining, RLHF, Constitutional AI and the constitution/character, and the limitations that follow from them (cutoff, hallucination).+
• Video 87:30The Claude model family and how to choose a modelTiers, current models, which model to use when, history, model lifecycle, model cards and benchmarks, and how to answer Claude vs GPT vs Gemini.+
• Video 96:23How claude.ai works internallyA trace of one real request (with web search) and how the app's features are internally a combination of model, context and tools.+

• Video 127:19Reducing hallucination, new-model prompting and use-case templatesWays to reduce hallucination, how prompting changed for newer models (what replaces prefill), and support bot, routing and extraction templates.+
• Video 138:13Claude API fundamentalsSetup, your first request, parameters, the response and stop_reason, the multi-turn format, API versioning and beta headers.+

• Video 166:06Extended thinking, adaptive thinking and effortThinking configuration, effort levels, the old budget_tokens approach vs the new adaptive approach, and preserved thinking.+
• Video 176:48Prompt caching: request 1 vs request 2A cache is a prefix match; cache write and read cost, breakpoints, ordering, and a cache-friendly agent loop.+
