Brief

0xSero emphasizes reducing cost barriers for capable models: DS4-Flash can run on $2.5–4.5k setups versus prior $9k–$20k requirements. On 2026-06-20 Topi Santakivi tried DS4-Flash REAP, used the Simon Willison-style pelican test to build a 2D pelican bike game, and demonstrated the model fixed errors after targeted instructions (video linked).

Why it matters

Author @0xSero states their mission is making high-quality models cheaper; DS4-Flash now runs on $2.5–4.5k hardware compared with the $9k–$20k previously needed.

Key details

Topi Santakivi (@sandst1) tested DS4-Flash REAP on 2026-06-20 by building a 2D 'pelican bike' game (Pelican test). The model didn’t get everything right initially but successfully corrected mistakes when instructed; a video demo was posted.

Source evidence

My mission has been to get good models accessible for cheaper and cheaper price points.

DS4-Flash now runs on 2.5-4.5k USD and offers a unique highly capable model when you would have needed 9k - 20k just to run it

Gave DS4-Flash REAP a try today and as a vibe check and in the spirit of @simonw pelican test created a 2d pelican bike game. Seems like a nice model. Didn't get everything right the first time but also succeeded in fixing things when instructed that something was wrong.
