开放模型的繁荣生态
阅读原文· tomtunguz.com开放模型在OpenRouter上的token份额已到69%，而且每轮新模型发布都会把使用量推上一个台阶，做推理基础设施的应该重视这个信号。
根据OpenRouter平台数据，自2025年以来，开放模型使用量显著增长。最新数据显示，开放权重模型产生了69.1%的token使用量，闭源模型为30.9%。新模型的发布会吸引开发者测试，推动token使用量达到新的平台期。开放模型市场内部竞争激烈，领导地位频繁更迭，如DeepSeek的早期优势在2025年末至2026年初被MiniMax与Kimi模型取代，随后MiMo、Qwen、腾讯Hy3、阿里巴巴及Arcee等模型的发布再次改变了份额格局。尽管开放模型目前仍只占推理总量的一小部分，但激烈的竞争与增长表明，开发者正越来越愿意将生产流量路由至开放模型。
Competition is a discovery procedure. — Friedrich Hayek
And developers are discovering the value of open models.
OpenRouter offers a useful view into the model market.1 It is not the whole AI economy. But it is close to the API frontier, where developers can switch models quickly, compare price-performance daily, & route each request to the best available option.
Since 2025, open models have grown sharply on OpenRouter. In the latest model-level snapshot, open-weight models generated 69.1% of named open-versus-closed token volume. Closed models produced 30.9%.
New models attract developer attention & large scale testing, after which token use surges. Each new clustered release of different models sustains a new plateau of token volume.
Just as in the closed-model ecosystem, the competition among open models means rapid innovation & leaderboard changes.
DeepSeek’s early lead gave way to MiniMax & Kimi models in late 2025 & early 2026. Later, launches from MiMo, Qwen, Alibaba’s open-weight model family, Hy3, Tencent’s open-weight model release, & DeepSeek reshuffled share again.
Arcee, a US lab focused, makes a strong appearance recently.
Open models still represent a fraction of overall inference, but the thriving competition, increasing usage, & surge of experimentation suggest developers are increasingly willing to route production traffic to them.
