dotey: DeepSeek V4.1 Flash builds landing pages and dashboards surprisingly well
dotey · x · 2026-10-31
dotey shares a hands-on test of building with DeepSeek V4.1 Flash, noting that writing a dsh plugin was easier than expected — just feed the official docs to Opus 5.5 and state the requirements — and that DeepSeek 4.1 Flash also produces solid results.
Screenshots show several real outputs: a coffee subscription landing page with in-canvas @agent copy editing (revisions done in 15 seconds), a daily water-intake line chart dashboard generated from a CSV in about 90 seconds, and a multi-slide deck with emoji formatting. Usage panels show 430k–614k tokens per task with 95–98% cache hits, i.e. very low cost.
