Why we picked it

Thinking Machines 把 Inkling 2 Small 权重放出来了，Apache 2.0 许可商用没问题。WebDev 拿了 1647 分，比上代多 239 分，美国开源模型里排第一。做前端网页生成的开发者可以拉下来跟 Qwen、DeepSeek 的代码模型对比一下。

Thinking Machines 正式开源 Inkling 2 Small，权重以 Apache 2.0 许可证在 HuggingFace 上供下载。在 Code Arena: WebDev 排行榜上，它以 1647 分成为美国开源模型第一名，全球开源模型中排第 4，总榜排第 23。

Body

相比前代 Inkling-Small 的 1408 分（开源模型第 34 名），Inkling 2 Small 提升 239 分。这使其在 WebDev 专项榜单上超过此前排名更高的开源模型，成为美国团队开源代码模型的代表成绩。

在开源代码模型领域，Qwen、DeepSeek 等中国团队长期占据榜单前列，Inkling 2 Small 的出现让美国开源模型在 WebDev 场景首次登上榜首。权重完全开放且许可证宽松，开发者可直接下载微调部署。

Inkling 2 Small Runs on vLLM From Day Zero

Day-zero vLLM support plus single-node GB200 fit means operational cost of serving this model is far lower than typical 594B-scale deployments. Engineering teams running self-hosted inference should benchmark the 630 tok/s TP4 figure against their current MoE serving setups, since the DSpark speculator and NVFP4 experts are the levers behind it. Teams needing 1M-token multimodal context without multi-node clusters have a concrete new option to evaluate.

Thinky Machines releases Inkling 2 Small weights on HuggingFace

License terms, not model size, are the real differentiator here: Apache 2.0 lets enterprises ship commercial products without the compliance overhead that Llama's custom license imposes. Teams evaluating self-hosted models for cost control or data privacy can fine-tune and deploy Inkling 2 Small with no royalties and no obligation to release source code. Engineering leads comparing open-weight options should shortlist it alongside other permissively licensed releases rather than treating all "open" models as equivalent.

Inkling 2 Small climbs Agent Arena ahead of open-weight release

The notable shift is that a US open-weights contender is now nearly matching Chinese leaders like Kimi K3 and DeepSeek on agentic tasks while costing 70% less per task. Teams evaluating open models for self-hosted agents or fine-tuning pipelines should benchmark it against Kimi K3 (Max) and DeepSeek-V4.1-Flash once weights land. It is already usable on Tinker today, so early adopters can fine-tune and test before the full release.
