Mano-P On-Device GUI Agent, Cider SDK, Mano-AFK Open-Source
Mininglamp-AI has open-sourced a full on-device GUI agent stack for Apple Silicon that includes the Mano-P 1.0-4B local model, the Cider INT8 activation quantization inference SDK, and Mano-AFK (an end-to-end automated app builder). The stack is designed to run entirely offline so screenshots and task data remain on-device. Mano-P uses a three-stage training pipeline (SFT → Offline RL → Online RL) and a think-act-verify loop; benchmarked results are reported for larger Mano-P variants. Cider provides W8A8 and W4A8 modes via custom Metal kernels to enable INT8 activation quantized inference on MLX, claiming measurable prefill speedups versus MLX native modes. The release includes hardware guidance, performance figures, GitHub repos, and downloads on HuggingFace and ModelScope. Publication date: 2026-05-06.
Provides an open-source, privacy-preserving on-device GUI agent stack and an INT8 activation quantization SDK that can materially affect local inference workflows on Apple Silicon; relevant to developers and enterprises prioritizing privacy and offline agent capabilities.

Key Takeaways & Evidence Grounding
- Mininglamp-AI open-sourced Mano-P 1.0-4B local model, Cider SDK, and Mano-AFK on 2026-05-06.
- Mano-P is a GUI‑VLA (Vision-Language-Action) agent using a three-stage training pipeline (SFT → Offline RL → Online RL) with a think-act-verify loop.
- Cider is an open-source INT8 activation quantization SDK for macOS that implements W8A8 and W4A8 modes via custom Metal kernels and MLX custom primitives.
- Mano-P 1.0-4B runs on Apple Silicon offline; recommended hardware includes Apple M4/M5 (or above) with 32GB+ unified memory or a Mano-P compute stick via USB 4.0.
- Performance claims: Cider W8A8 shows ~12.7% prefill speedup (Mano-P decode ~79–80 tokens/s on Apple M5 Pro) and end-to-end VLM acceleration of 1.4x–2.2x prefill speedup vs MLX native W4A16.

Mano-P: Open-Source On‑Device GUI Agent; Apple CEO Change
The article introduces Mano-P, an open-source, on-device GUI Agent for macOS that uses a pure-vision approach to operate graphical interfaces. Mano-P is released under Apache 2.0 (GitHub: Mininglamp-AI/Mano-P) and provides a three-stage training pipeline (Supervised Fine-Tuning, Offline RL, Online RL) plus a think-act-verify inference loop for self-correction. Benchmarks report a 58.2% success rate for Mano-P's 72B model on OSWorld and a 41.7 NavEval score on WebRetriever Protocol I, outperforming several contemporaries. A quantized 4B w4a16 model is shown running locally on Apple M4 Pro (476 tokens/s prefill, 76 tokens/s decode, 4.3 GB peak memory). The piece also notes Apple announced Tim Cook will step down to Executive Chairman with John Ternus becoming CEO on September 1.
Mano-P: Edge-Native AI Agent Restores Data Sovereignty
The article presents Mano-P, an open-source, edge-native AI agent architecture designed to run entirely on local hardware to preserve data sovereignty and reduce cloud dependencies. Mano-P uses vision-only understanding (screenshots as raw pixels), w4a16 quantization, and GS-Pruning to run a 4B-parameter model interactively on consumer Apple Silicon. Measured on an Apple M4 Pro (32GB), the model shows 476 tokens/s prefill, 76 tokens/s decode, and 4.3 GB peak memory. Benchmarks cited include a 58.2% success rate on OSWorld and 41.7 NavEval on WebRetriever Protocol I, outperforming larger cloud models in GUI automation tasks. The project follows a three-stage training pipeline (SFT, offline RL, online RL), supports local USB 4.0 accelerator offload, and is being released in phased open-source stages under Apache 2.0.
Local AI Becomes Default for Developers
A DEV Community analysis argues that "local AI" (running models and agents on-device) has become the practical default for many developers. The article points to a viral Hacker News post in early 2025 that gathered 1,763 upvotes and 800+ comments as evidence of developer sentiment. It cites advances in consumer hardware (Apple M‑series chips and MLX), inference tooling (llama.cpp, Ollama), open-weight model availability (Hugging Face ecosystem) and quantization techniques (GGUF, AWQ, GPTQ) as the technical convergence enabling local inference. The piece highlights use cases—privacy, latency, cost, offline availability and reproducibility—and describes on-device GUI agents as the next step. Mininglamp Technology published Mano-P, an open-source, on-device vision-first GUI agent for Mac (Apache 2.0) that the article says leads an OSWorld benchmark with 58.2% accuracy and runs a 4B quantized model on an M4 Pro at quoted throughput and memory figures.
