DeepSeek's Liang Wenfeng: strongest models may be open-sourced, same model as deployed internally

teortaxesTex · x · 2026-10-28

teortaxesTex parses two quotes from DeepSeek founder Liang Wenfeng's investor call: "we will open-source, and even our strongest model may be open-sourced," and "we won't open-source a weaker model while deploying a better one ourselves—it will be the same model." He reads this as a costly commitment, possibly implying completed models never released or served. Follow-up: the rumored V5 code trail turned out to be September assert tests—no V5 soon. Screenshots add Liang's fuller argument: closed source offers no benefit (citing ByteDance), open source coexists with commerce if priced at 10-month payback, third parties can't match DeepSeek's deployment costs, and the company's goal is AGI.
