结构时间轴展开收起

FoR--Bsef_s 0:00–1:04 — Last time, the robot picked one word at a time. Today: what it actually reads, and how much it can read at once. Priya: Two problems at the bank this week.
FoR--Bsef_s 1:11–2:13 — Priya: Then I need to know what fits, and how it's measured. What the model really reads, and what you pay for. A hard limit on how much fits in one call.
FoR--Bsef_s 2:18–3:22 — Dev: That's the closer picture for one call. Too big is an error, not a partial read. By default, a Kafka broker takes batches of about one megabyte.
FoR--Bsef_s 3:31–4:31 — Each piece is swapped for a number from a fixed vocabulary. Priya: The model never sees letters, then. Dev: And each of those numbers is one token.
FoR--Bsef_s 4:36–5:37 — A hundred tokens is roughly seventy-five words. Dev: Then use your provider's token counter. Priya: Why does it matter that it's tokens and not words?
FoR--Bsef_s 5:42–6:48 — Priya: Then the statement they attached. Priya: And the newest email goes in last. Dev: One slot left, and the model needs it to write its reply.
VSFuqMh4hus 0:00–1:06 — There are two things that hold true when it comes to artificial intelligence. My toothbrush just got an AI update this week.
VSFuqMh4hus 1:10–2:13 — Then they move on to act on the plan that it's built through the reasoning, and then observes the results of that action.
VSFuqMh4hus 2:15–3:19 — Now, the reasoning model is trained on problems with verifiably correct answers.
VSFuqMh4hus 4:25–5:26 — Now vector databases, they play a big role in implementing number four. And that is RAG or retrieval augmented generation.

字幕依据：Last time, the robot picked one word at a time. Today: what it actually reads, and how much it can read at once. Priya: Two problems at the bank this week. Priya: A customer wrote fourteen emails about one complaint. Priya: A developer on their team fixed it by cutting the oldest emails. FoR--Bsef_s@0:00
字幕依据：Priya: Then I need to know what fits, and how it's measured. What the model really reads, and what you pay for. A hard limit on how much fits in one call. Priya: And how to choose what goes in, when it doesn't all fit. Dev: Start with something you've built a hundred times. FoR--Bsef_s@1:11
字幕依据：Each piece is swapped for a number from a fixed vocabulary. Priya: The model never sees letters, then. Dev: And each of those numbers is one token. The exact cuts depend on the model's tokenizer, but the pattern holds. A short, common word, like the, is usually one token. FoR--Bsef_s@3:31
字幕依据：A hundred tokens is roughly seventy-five words. Dev: Then use your provider's token counter. Priya: Why does it matter that it's tokens and not words? Dev: Because tokens are what you pay for. Output tokens usually cost more, and they come out one at a time. FoR--Bsef_s@4:36
字幕依据：Now, the reasoning model is trained on problems with verifiably correct answers. So math problems or code that can be tested by compilers and through reinforcement learning, the model learns to generate reasoning sequences that lead to correct final answers. VSFuqMh4hus@2:15
字幕依据：Now vector databases, they play a big role in implementing number four. And that is RAG or retrieval augmented generation. Now, RAG makes use of these vector databases. And it uses it to enrich prompts to an LLM. So, we start here with a RAG retriever component. VSFuqMh4hus@4:25
字幕依据：And then this RAG system is going to pull the relevant section from the employee handbook to include in the prompt. Now, number five, that Model Context Protocol or MCP. This is a really exciting one because for large language models to be truly useful, they need to interact with external data sources and services and tools. VSFuqMh4hus@5:30
字幕依据：And that is how the AI knows exactly what to do to get through to any one of these tools. It connects through that MCP server connection. And we've had the idea of MOE for a good while, actually, since the paper was published in a scientific journal in 1991. VSFuqMh4hus@6:36
