## Questions the record answers

**Which log management platform do AI models name first most often?** Datadog Log Management, in 28% of first choices for a mid-market B2B company in the October 2026 Edition, from 64 labels. The standing is contested: the models did not settle on one product.

**Does the answer change with the size of the company?** Small business: Better Stack at 32%. Mid-market: Datadog Log Management at 28%. Enterprise: Splunk at 46%. Each standing is computed within its segment and never pooled.

**Which framing changes the answer?** The direct, paraphrase, budget and scale framings count toward share. The product named first differs by framing: direct Datadog Log Management; paraphrase Datadog Log Management; comparative Splunk; budget-constrained Grafana Loki; scale-constrained Datadog Log Management; negative Grafana Loki. The table above has the counts.

**How stable is one answer?** Asked again with nothing changed, the models moved their own first choice 63% of the time across the repeat sample; Across the categories asked twice, a leader's share moved 4 points at the median and the index calls a change only above 11 points.

**Where do the answers come from?** Fourteen of the fourteen models return sources. Their 73 answers here cite 992 pages; the sites cited most are cribl.io, middleware.io, openobserve.ai. The category page lists them all.

**Can a vendor pay to be on this list?** No. A product is on the record because a model named it. A vendor can claim its page, propose corrections to the vendor table and be told when its standing moves; it cannot change a label, a share or a rank, and the publisher's conflicts are disclosed on the method page.
