Open Horizon

Local Android AI agent powered by MNN and K2 Horizon 0.9B. Private workspace, web research and file tools.

A minimal Android app for running a local AI agent. Powered by the pinned IFM llama.cpp GGUF runtime with K2 Horizon 0.9B Q5_K_M as the default model.

Features Local GGUF inference on CPU.

Chat, deep research, coding, thinking/output budgets, context and resource controls.

Web search and page reading, file creation and editing, offline HTML preview.

Agent file tools restricted to one app-owned workspace.

Resumable, checksum-verified model downloads; storage information and explicit model deletion.

App updates retain models and chats when installed with the same package and signing key.

Web tools and model downloads require internet access. Chat inference stays on the device. Small-model tool use and generated code can fail; advanced 3D scene generation is experimental and has not passed our tests. KV cache is Q8_0 by default, with Q5_0 available separately from weight quantization. No NPU support is claimed.
