Release notes:

MiniCPM-V Demo for Android — v2.0

Major release. The native multimodal pipeline has been re-platformed onto llama.cpp's master branch and the model download flow is now multi-source. Recommended upgrade for everyone on v1.7 / v1.9.

What's new

🧩 Master mtmd bridge (`MBMtmd`)

• Native layer is rebuilt on top of llama.cpp master's mtmd (multimodal) implementation. Same code path now drives iOS, Android, and HarmonyOS — the three platforms stay in lock-step from this version onward.
• ubatch is now tier-aware: split sizes adapt to device class so low-end SoCs no longer choke during prefill.

🌐 Racing dual-source download

• The in-app Model Manager races HuggingFace and ModelScope in parallel and uses whichever responds first. Massive win on networks where one of the two CDNs is slow or unreachable; cancels the loser to avoid wasting bandwidth.

🇨🇳 No more "English-by-default" answers

• The default system prompt has been dropped on MiniCPM-V 4.6, both in Java/Kotlin and in the native processUserPrompt path. Chinese questions now answer in Chinese instead of being silently steered to English.

Other changes

• All carry-over fixes from v1.9 (dynamic CPU dispatch for ggml-cpu) and the v1.8 video-understanding work (uniform-sample 64 frames, V4.6 nCtx=8192, prefill slice=1) remain in place.

Requirements (unchanged)

• Android 8.0 (API 26) or later
• 64-bit ARM (arm64-v8a)
• ≥ 6 GB RAM recommended (≥ 8 GB for MiniCPM-V 2.6)
