OpenBMB MiniCPM Spark S1 挑战赛收官：16 个获奖项目展示小模型落地场景
OpenBMB 晒出了 MiniCPM 挑战赛的 16 个获奖项目，有 Mac mini 上的摄像头助手把调用从 720 次砍到 60 次，还有配音工具和自蒸馏训练数据全开源，做端侧部署的可以抄作业。
OpenBMB 的 MiniCPM Spark Program S1 挑战赛结束，共产生 16 个获奖项目，开发者来自中国、西班牙、意大利、澳大利亚和美国。获奖项目包括一个跑在 Mac mini M4 上的家庭摄像头助手，用轻量检测器过滤画面后调用 MiniCPM-V，将每日模型调用从约 720 次降到 60-70 次。其他项目还有基于 ESP32-S3 和 MiniCPM5-2B、VoxCPM2 的桌面飞行雷达，用单个量化 MiniCPM-o 4.5 实例切换三种角色的 Reachy Mini Lite 机器人，浏览器端视频配音工具 Dubedo，以及基于 MiniCPM5-2B 的自蒸馏训练实验 Neko-OPSD，后者公开了训练数据、脚本和 12400 条评估结果。
Small models, real-world impact. The MiniCPM Spark Program S1 challenge has wrapped up with 16 award-winning projects from developers across China, Spain, Italy, Australia, and the US! 🎉
Here’s a look at what the community built:
📷 A home camera assistant that cuts unnecessary inference Running locally on a Mac mini M4, a lightweight detector filters footage before MiniCPM-V analyzes relevant scenes and turns them into GIFs and daily reports. Model calls dropped from around 720 per day to just 60–70.
📡 A talking desktop radar An ESP32-S3 displays flight tracks and plays audio, while API calls to MiniCPM5-2B and VoxCPM2 provide tower-style announcements and speech. The demo uses simulated flight data. A small device, brought to life through hardware and model collaboration
🤖 One robot, three roles Powered by a single quantized MiniCPM-o 4.5 instance running on an NVIDIA GB10 system, a Reachy Mini Lite switches between companion, product guide, and performer without reloading model weights.
🎙️ Video dubbing you can keep refining Dubedo brings VoxCPM2 into a browser-based workspace where creators can edit dialogue, regenerate individual lines, preview audio, and export the mix.
🧪 Training experiments others can build on Neko-OPSD explores self-distillation with MiniCPM5-2B, sharing training data, methods, scripts, and 12400 evaluation responses across five experimental runs so others can inspect the results and build on the work.
Across applications, deployment tools, and training research, these projects show how much thoughtful engineering matters: choosing the right inputs, connecting components, testing limits, and sharing what actually worked.
Congratulations to all the winners, and thank you to everyone who contributed projects, code, and lessons learned!
Building with MiniCPM? Share your setup, model version, and real-world results with the OpenBMB community. Your experiment could help another developer take their next step.
S1 is complete. The exploration continues. See you next season!
