If the likelihood is known, inference can proceed using standard techniques. However, when the likelihood is intractable or unknown, a simulator makes it possible to infer the parameters of a theoretical model directly from real and simulated observations when coupled with machine learning. We introduce an extension of the recently proposed likelihood-free frequentist inference (<jats:monospace>LF2I<\/jats:monospace>) approach that makes it possible to construct confidence sets with the <jats:italic>p<\/jats:italic>-value function and to use the same function to check the coverage explicitly at any given parameter point. Like <jats:monospace>LF2I<\/jats:monospace>, this extension yields provably valid confidence sets in parameter inference problems for which a high-fidelity simulator is available. The utility of our algorithm is illustrated by applying it to three pedagogically interesting examples: the first is from cosmology, the second from high-energy physics and astronomy, both with tractable likelihoods, while the third, with an intractable likelihood, is from epidemiology\n                  <jats:sup>3<\/jats:sup>\n                  <jats:fn id=\"mlstad218efn2\">\n                     <jats:label>3<\/jats:label>\n                     <jats:p>Code to reproduce all of our results is available on <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/github.com\/AliAlkadhim\/ALFFI\" xlink:type=\"simple\">https:\/\/github.com\/AliAlkadhim\/ALFFI<\/jats:ext-link>.<\/jats:p>\n                  <\/jats:fn>.<\/jats:p>","DOI":"10.1088\/2632-2153\/ad218e","type":"journal-article","created":{"date-parts":[[2024,1,23]],"date-time":"2024-01-23T22:24:32Z","timestamp":1706048672000},"page":"015020","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Amortized simulation-based frequentist inference for tractable and intractable likelihoods"],"prefix":"10.1088","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3490-8407","authenticated-orcid":true,"given":"Ali","family":"Al Kadhim","sequence":"first","affiliation":[]},{"given":"Harrison B","family":"Prosper","sequence":"additional","affiliation":[]},{"given":"Olivia F","family":"Prosper","sequence":"additional","affiliation":[]}],"member":"266","published-online":{"date-parts":[[2024,2,2]]},"reference":[{"key":"mlstad218ebib1","doi-asserted-by":"publisher","first-page":"305","DOI":"10.1038\/s42254-021-00305-6","volume":"3","author":"Brehmer","year":"2021","journal-title":"Nat.
