- DeepSeek V4 Flash IQ2XXS on custom ds4-server. Full Foundry eval: 35/37 passed (13 core, 15 instruct-15, 9 supplemental). Landing-page and build-hard failed at 8192 token output limit (reasoning model burns tokens on thinking). Steady-state ~33 t/s. Cold start penalty on first request (211s for 462 tokens). Flappy Bird game generated complete and playable. Landing page scored 1/10 on quality review. Not promoted as primary lane.
