DeepSeek V4.1 Flash generates a code-only 3D steam-harbour open world in 152M tokens
A hands-on test has ds-v4.1-flash build a procedural steam-harbour 3D open world with PBR materials, SSAO, SMAA and a day/night cycle all in code, using 152M tokens at 99.8% cache hit.
Another massive win for deepseek-v4.1-flash-1017 in my tests. With @DeepSeekHarness ds-v4.1-flash build me this amazing 3D open world, a procedural steam-harbour city: masonry viaduct carrying a working steam railway, airships, a sea fort, and a full day/night cycle. The details are where it won me over: PBR materials, sky-based lighting, reflections, SSAO and SMAA all generated in code. No downloaded models, textures, fonts or audio. Every brick, wave and cloud is code. 152M tokens in total Cache hit 99.8% Uncached input 311,373 tokCached input 151,808,128 tokOutput 319,062 tok
