AA-Briefcase v1.1

Ranks compare reported scores in the same published row; ties share a rank.

AA-Briefcase v1.1 (max). Elo from Artificial Analysis, quoted by Anthropic.

All eight results and four comparison columns from Anthropic’s announcement, read 8 October 2026. Haiku 5.5 uses max effort; Sonnet’s FrontierCode uses xhigh. HLE is split into no-tools and with-tools rows. OSWorld uses partial credit on the official 82-task offline subset, differing from earlier combined-subset reports. AA ran GDPval-AA and AA-Briefcase; these rounded quotes from Anthropic remain separate from the directly imported public AA measurements. GPT results retain the source and configuration described in the system card. Missing cells stay blank; the reported Haiku 4.5 Terminal-Bench score is zero. Each rank compares one published row only.

AA-Briefcase v1.1 (max). §8.10.3: independent AA long-horizon knowledge-work evaluation quoted by Anthropic.

AA-Briefcase v1.1 (medium). §8.10.3: default medium effort, under one quarter of max’s output tokens. Comparison-model medium figures are not stated.

Section 8, pages 111–139 of the Haiku 5.5 system card, read 8 October 2026. Values come from exact prose, tables and labelled figures. Unless specified, Haiku uses adaptive thinking at max effort and five trials with evaluation-specific context up to 1M. Each row retains its subset, metric, effort and source notes; no score is assigned to an unspecified SWE-Bench Pro version. Terminal runs use safeguards without fallback and no internet egress. ProgramBench uses filtered tasks and hidden-test pass rate without a time limit. OSWorld partial and strict results use the official 82-task offline subset. CAD uses 0–1 voxel IoU. Healthcare raw and length-adjusted scores stay separate. Life-science results disable Haiku biology safeguards. Independently run figures quoted by Anthropic remain publisher reports here. Missing comparison values are not inferred from rounded charts.

AA-Briefcase v1.1. An Elo-style score from Artificial Analysis's long-horizon knowledge-work benchmark, quoted here as Anthropic published it.

Anthropic publishes this table with Sonnet 5.5, the second model in its Claude 5.5 line, and states that Sonnet 5.5 at Max effort performs comparably to Opus 5.5 on several evaluations while Opus 5.5 remains stronger on open-ended work. The GPT-6 Sol column is quoted from OpenAI, not re-run, and Anthropic notes an OpenAI image-understanding bug that may not yet be reflected in third-party scores. Two rows come from other publishers: Artificial Analysis ran GDPval-AA and AA-Briefcase on a pre-release Sonnet 5.5 deployment that Anthropic later found had a structured-output bug, and Surge AI runs Chartography. Sonnet 5.5 launched with the cyber safeguards first built for Opus-class models, so some security work was completed by a fallback model.
