LatentSpace's first model review: Naive-N0.5-Flash beats DeepSeek on coding, hits 2100 tokens/s

量子位 · wechat · 2026-11-13

LatentSpace launched a new hands-on model review series, testing NaiveAI's open-source Naive-N0.5-Flash (founded by Dai Jifeng) against OpenRouter favorites DeepSeek V4.1 Flash 1017 and GLM 5.3 Flash.

Key findings: overall capability sits between the two rivals; on the NL2Repo-Bench coding benchmark it scored 71.9, beating both. Speed is its standout: 2100 tokens/s peak, with thinking-mode median response time of 3.1s vs DeepSeek's 10.1s (3.3x faster). In three coding tests (3D solar system, growing tree, ray tracing) it matched top-tier quality. NaiveAI also runs an AI-driven R&D pipeline with 10M sandbox runs weekly.
