Linus Lee: commitment

…page. A page could contain anything from no information, if it's a fresh document, to a fully fledged news article. Maybe it's a meeting note. Maybe it's a bug filed by somebody at a company. The range of possible documents is huge. And then you have to distill all of it down to always generate a summary. And so describing that task to AI comprehensively is pretty hard. There are a few things that I think I ended up leaning on, as a team we ended up leaning on, for the prompt engineering part of it. I think one of the early transitions that we made was that the initial prototype for Notion AI was built on instruction following, the sort of classic instruction following models, TextWG003, and so on. And then at some point, we all switched to chat-based models, like Claude and the new ChatGPT Turbo and these models. And so that was an interesting transition. It actually kind of made few-shot prompting a little bit easier, I think, in that you could give the few-shot examples as sort of previous turns in a conversation. And then you could ask the real question as the next follow-up turn. I've come to appreciate few-shot prompting a lot more because it's difficult to fully comprehensively explain a particular task in words, but it's pretty easy to demonstrate like four or five different edge cases that you want the model to handle. And a lot of times, if there's an edge case that you want a model to handle, I think few-shot prompting is just the easiest, most reliable tool to reach for. One challenge in prompt engineering that Notion has to contend with often is we want to support all the different languages that Notion supports. And so all of our prompts have to be multilingual or compatible, which is kind of tricky because our prompts are written, our instructions are written in English. And so if you just have a naive approach, then the model tends to output in English, even when the document that you want to translate or summarize is in French. And so one way you could try to attack that problem is to tell the model, answering the language of the user's query. But it's actually a lot more effective to just give it examples of not just English documents, but maybe summarizing an English document, maybe summarize a ticket filed in French, summarize an empty document where the document's supposed to be in Korean. And so a lot of our few-shot prompt-included prompts in Notion AI tend to be very multilingual, and that helps support our non-English-speaking users. The other big part of prompt engineering is evaluation. The prompts that you exfiltrated out of Notion AI many weeks ago, surprisingly pretty spot-on, at least for the prompts that we had then, especially things like summary. But they're also outdated because we've evolved them a lot more, and we have a lot more examples. And some of our prompts are just really, really long. They're like thousands of tokens long. summary. But they're also outdated because we've evolved them a lot more, and we have a lot more examples. And some of our prompts are just really, really long. They're like thousands of tokens long. And so every time we go back and add an example or modify the instruction, we want to make sure that we don't regress any of the previous use cases that we've supported. And so we put a lot of effort, and we're increasingly building out internal tooling infrastructure for things like what you might call unit tests and regression tests for prompts with handwritten test cases, as well as tests that are driven more by feedback from Notion users that have chosen to share their feedback with us.…
