Tether — yes, the stablecoin company — has launched QVAC, a fully open-source SDK for building on-device AI agents that work offline, peer-to-peer, and without any dependency on centralized cloud infrastructure. Built on a customized fork of llama.cpp called QVAC Fabric, it supports text completion, embeddings, vision, OCR, speech-to-text, text-to-speech, and translation — all running locally on Linux, macOS, Windows, Android, and iOS with a single unified API. What makes QVAC architecturally distinct is the Holepunch protocol stack underneath it: models can be distributed peer-to-peer, inference can be delegated across devices without centralized infrastructure, and the roadmap includes decentralized swarms for training and fine-tuning. Once a model is cached locally, the SDK works fully offline — making it suitable for air-gapped deployments, field work, and restricted-network environments. Tether is also running a developer grants program to fund projects building with QVAC, specifically targeting local-first AI and payment applications. With $27B+ in stablecoin reserves behind it, Tether has the runway to sustain a multi-year open-source effort here — which is more than most AI SDK projects can say.

VibeAround is a 15 MB Tauri desktop app that creates a real-time bridge between your local coding agent and your preferred messaging apps — so you can start a Claude Code or Gemini CLI session on your laptop, then continue it from Telegram on your phone while you're away from your desk. The bridge works by running a lightweight local server that the messaging platform connects to. Supported agents include Claude Code, Gemini CLI, Codex CLI, Cursor, and any agent with a terminal interface. Supported platforms: Telegram, Slack, Discord, and Feishu. Mid-session agent switching lets you hand a conversation from Claude Code to Gemini CLI without losing context. Session handover between terminal and mobile preserves full conversation history. For developers who want agentic coding to feel less desk-bound — reviewing PRs during a commute, checking on long-running tasks from a phone, or directing an agent while walking — VibeAround is a small but genuinely useful quality-of-life tool. The 15 MB binary (Tauri is tiny vs Electron) and open-source release keep it lightweight and extensible.
Reviewer scorecard
“A single API covering text, vision, speech, OCR, and translation — locally, cross-platform, offline — built on llama.cpp with P2P model distribution via Holepunch. This is the toolkit for building genuinely private AI apps, especially on mobile where on-device inference is finally practical.”
“I run Claude Code on long research tasks that take 10-15 minutes. Being able to check progress and redirect from Telegram while I make coffee is genuinely useful. The Tauri footprint is tiny — it doesn't slow my machine down sitting in the background. Session handover between terminal and mobile works cleanly for Claude Code.”
“Tether's business is stablecoins, and grafting a major open-source AI SDK onto that brand is an unusual strategic move that raises questions about long-term commitment. The Holepunch P2P stack is powerful but adds significant complexity — most developers just want a simple local inference wrapper, not a decentralized agent protocol.”
“Any tool that routes your coding agent's output through a third-party messaging platform introduces a potential data exfiltration path. If the Telegram bridge is configured carelessly, your agent's filesystem access and code outputs could be intercepted or leaked. The security model needs more documentation before I'd use this at work.”
“QVAC represents the counter-narrative to cloud AI monopolization: intelligence that lives on devices, syncs peer-to-peer, and never phones home. Combined with Tether's payment rails, this could be the foundation for AI agents that transact autonomously in a fully decentralized stack.”
“The idea that your coding agent lives on your laptop but you interact with it from anywhere is the right mental model for the next generation of development workflows. VibeAround is a rough first version of what will eventually be a native capability in every IDE and coding agent platform.”
“Local speech-to-text, translation, and OCR with one SDK, working offline on my phone? The creative use cases — offline transcription in the field, private on-device captioning, local image analysis — are immediately compelling without needing to trust a cloud provider with my content.”
“I've started using Claude for file organization and content processing tasks that run in the background. Checking on those from my phone via Telegram — instead of switching back to my laptop — is a small workflow win that adds up. The Slack integration is key for people whose work lives in Slack.”
