DeepSeek V4.1 Flash tested: 300-400+ tok/s, cheap and fast, but prone to overthinking
WorldofAI · youtube · 2026-09-09
- YouTuber WorldofAI ran a full hands-on test of DeepSeek V4.1 Flash across coding, 3D simulations, Three.js environments, Minecraft and Mario Kart-style games, rocket simulations, autonomous dungeon games, exploded camera views and vision tasks.
- The model hits roughly 300-400+ tokens per second in some tests, delivers surprisingly strong results at a very competitive price, and feels like a major improvement over previous DeepSeek Flash releases.
- Caveats: it can overthink, spends too much time testing, and occasionally struggles with instruction following.
