Anthropic's proposal
Claude Sonnet 5.5 was introduced on 28 September 2026 for focused everyday tasks, bug fixes and preparing documents, presentations and spreadsheets. Anthropic reports speed and efficiency improvements over Sonnet 5.
In its comparison, Anthropic reserves Opus 5.5 for more open-ended work demanding sustained judgement. That positioning helps design a test, but does not establish which performs best on an organisation's documents and processes.
A sales presentation with checkable data
Prepare a presentation from an approved product dossier. Specify audience, duration, permitted messages and publishable examples. Require important claims to link to their sources and missing material to be flagged.
Human review should assess clarity, fidelity and usefulness. Attractive design cannot compensate for invented figures or impossible promises. The employee can produce alternatives while people decide how to present the business.
An evaluation the team can repeat
Use the same dossier and instructions for all trials. Record requested changes, preparation and correction time. Check the exported document's links, tables, clipped text and consistency with the employee's explanation.
A useful procedure can become a skill for other products, retaining review requirements and publishing permissions. This article proposes a workflow; it does not report a Sonnet 5.5 Hub Bot trial or measured superiority.
