DeepSeek 4.1 flash can near-match Opus 5.5's code-built Greek world with the right harness
victormustar · x · 2026-10-19
After extensive testing, victormustar argues that with enough time, tokens, and subagents in a proper harness, DeepSeek 4.1 flash can build an ancient Greek world quite close to what Opus 5.5 produced in @LexnLin's demo — a fully code-generated world using no assets. Side-by-side images show the two models' shop builds are remarkably close. Not better than Opus 5.5, but open-weights means you own it forever and can run it locally.
