Jason Liu (creator of Instructor) evaluates Anthropic's Claude 3 models against OpenAI models based on production workloads.
Insight
Liu: LLM observability startups ignore full systems; just use Postgres
“The issue really is the fact that these observability companies isn't actually doing observability for the system, it's just doing the LLM thing. Like I still end up using like Datadog, right? Or like, you know, Sentry to do, like, latency. And so I just have …”
Insight
Liu: Companies abandon LLM frameworks to regain control over prompts
“So much of it is changing that if you give control of these systems away too early, you end up ultimately wanting them back. Like many companies I know that I reach out or ones were like, oh, we're going off of the frameworks because now that we know what the …”
Opinion
Liu: App-layer AI startups should avoid hiring traditional machine learning engineers
“I think a lot of these app layer startups should not be hiring MLEs because they end up churning.”
Prediction Not checkable as stated
Liu: XGBoost rankers will beat LLMs for large-scale tool selection
“Yeah, my money is on the rankers because you can do those so easily, right? You could just say, well, given the embeddings of my search query and the embeddings of the description, I can just train XGBoost and just make sure that I have very high, like, MRR, w…”
Insight
Liu: AI agents should use explicit DAG workflows over ReAct loops
“Instead of doing like a react type reasoning loop, I think my belief is that we should be using like workflows, right? If we do this, then we always have a request and a complete workflow. We can fine tune a model that has a better workflow. Whereas it's hard …”
Opinion
Liu: LangChain and LlamaIndex can hit $100M revenue, but billions uncertain
“I think the bigger challenge is like, okay, a hundred million dollars, probably pretty, pretty easy. It's just time and effort. And they have both like the manpower and the money to sort of solve those problems. I think it's just like, again, if you go the VC …”
