I tried summarizing the thread so far (339 comments) with a custom system prompt [0] and a user-prompt that captures the structure (hierarchy and upvotes) of the thread [1].

This is the output that we got (based on the HN-Companion project) [2]:

LLama 4 Scout - https://gist.github.com/annjose/9303af60a38acd5454732e915e33...

Llama 4 Maverick - https://gist.github.com/annjose/4d8425ea3410adab2de4fe9a5785...

Claude 3.7 - https://gist.github.com/annjose/5f838f5c8d105fbbd815c5359f20...

The summary from Scout and Maverick both look good (comparable to Claude), and with this structure, Scout seems to follow the prompt slightly better.

In this case, we used the models 'meta-llama/llama-4-maverick' and 'meta-llama/llama-4-scout' from OpenRouter.
