What Hacker News says?
Meant as a comparison given the discrepant pricing points: I pay the Exa premium for semantic retrieval with far higher SNR, plus the academic index [1]. A field like objective can be up to 4096 characters [2] versus ori_question which is limited to 128 here. [1] https://exa.ai/blog/publications-search [2] https://exa.ai/docs/reference/search
