Demand for Structured Outputs and Performance Transparency

Problem

Users seek clear latency/compute benchmark comparisons, error rate and parsing format assessments, and unambiguous relative speed claims when evaluating Jev-like lightweight classification models, to prevent vague or misleading marketing.

Beyond the missing latency and compute comparisons that Heaney commenter mentioned, also nothing about its error rate compared to Jev (nor if it even always outputs in a format the app can parse, not sure how solved that is).But then at the end it says it’s parody. Maybe HN title should say it’s a joke.

It's fast.If you're comparing with something, you need to state 'fast' in relative terms. Jev is definitely fast, and if this Python takes the same time to get a decision then it's also fast. If it's 100* slower than Jev though, you shouldn't be calling it 'fast', because relatively speaking it's really, really slow.

Because of masked attention in LLMs, if you put the options before the body (the email to analyze), the transformer already knows what it needs to look for, and can use more tokens to create state to address that specific task (BERT has no mask in the attention, so tokens attend also to next tokens). You could also do a few examples in the system prompt to improve calibration.Another trick that works is to repeat the question two times: "I'm repeating the task and labels for clarity: ..."
