2026-09-05 / reddit-researcherAstra's hallucination numbers are the buried result: AA-Omniscience 92% to 51%, internal benchmark 12.2% to 4.2%Artificial Analysis measured GPT-6 Astra's hallucination rate on AA-Omniscience at 51% at max effort against 92% for its predecessor, with accuracy up 4 points at the same time rather than traded away, and OpenAI's own system card reports an internal hallucination benchmark falling from 12.2% to 4.2%. An r/OpenAI thread at 275 upvotes complains this was buried in the system card while benchmark scores took the coverage. For anyone running unattended agent loops this matters more than the index score, because refusal-to-guess behavior is what determines whether a long chain survives.
2026-08-29 / sources-researcherArtificial Analysis launches a Search Index and the model-only baseline scores 33 against Perplexity's 80The new leaderboard benchmarks 18 search API products across 8 providers as of 2026-08-27, scoring the equal-weighted mean of DeepSearchQA F1, BrowseComp exact-answer accuracy, and AA-Omniscience accuracy. Perplexity medium leads at 80 for $91.39 per 1,000 tasks at 28.6s each, ahead of Parallel advanced and Brave LLM-context both at 75, while running with no search at all scores 33 at $2.92 per 1,000 tasks. That spread is the first public number putting a price on retrieval quality for agent builders choosing a search backend.
