Baker's choice. Dense with flavour, light on filler.
Summary
OpenAI has released its first open-source large language models, gpt-oss-120b and gpt-oss-20b, which perform well in some benchmarks but struggle with others like SimpleQA. The models are technically competent but lack out-of-domain knowledge, such as popular culture. Public reactions are mixed, with some praising their capabilities while others criticize their limitations.
Key quotes
· 3 pulledOpenAI just released its first ever open-source large language models, called gpt-oss-120b and gpt-oss-20b.
They’re great at some benchmarks, of course (OpenAI would never have released them otherwise) but weirdly bad at others, like SimpleQA.
From what I can tell, they’re technically competent but lack a lot of out-of-domain knowledge: for instance, they have broad general knowledge about science, but don’t know much about popular culture.
