OpenSpace is an open-source MCP server from HKUDS (the lab behind DeepTutor) that gives AI agents persistent, shareable memory in the form of reusable skills. When an agent completes a task successfully, OpenSpace captures the strategy as a "skill" — a structured template that future agents can query and apply directly, bypassing the need to reason from scratch. Skills are versioned, ranked by success rate, and auto-repaired when they break. The system ships with a cloud skill-sharing registry at open-space.cloud, enabling teams to share and discover skills across agents and projects. A recent update added native adapters for WhatsApp and Feishu messaging. Early benchmarks on GDPVal show a 46% reduction in token usage and 4.2x productivity gains when skill retrieval is available versus cold-start reasoning. For teams running agentic workflows at scale, OpenSpace addresses a real architectural gap: agents today are fundamentally stateless, re-solving problems they've already solved. By converting successful runs into reusable knowledge capital, OpenSpace makes agent networks genuinely compound over time — a meaningful step toward the "improving over time" property that distinguishes a true agent system from a sophisticated LLM wrapper.

TurboQuant WASM ports the ICLR 2026 TurboQuant algorithm (Google Research) into a browser-native npm package using Zig, WASM, and WGSL compute shaders. It compresses embedding vectors ~6x (3–4.5 bits per dimension) and runs similarity search directly on compressed data — no decompression step. WebGPU acceleration delivers 30+ tok/s in Chrome. The demo shows Gemma 4 E2B generating Excalidraw diagrams from prompts with KV-cache compression cutting memory by 2.4x, enabling longer conversations inside browser GPU limits.
Reviewer scorecard
“The MCP server architecture means I can bolt this onto any existing agent stack without rewiring everything. A 46% token reduction on repeat workflows is a genuine cost win, and the auto-repair for broken skills means less maintenance overhead. HKUDS has a track record with DeepTutor — feels production-ready for v0.1.”
“Searching directly on compressed vectors without decompression is a real algorithmic win, not a marketing trick. The npm package with embedded WASM binary means integration is literally one import. The Excalidraw demo proving KV-cache compression in-browser is compelling proof that this works in production-like conditions.”
“Skill quality depends entirely on the quality of the tasks they derive from. If your first agent run is mediocre, you've enshrined that mediocrity as a reusable template. The 4.2x productivity benchmark needs independent replication — academic benchmarks rarely transfer cleanly to production workloads.”
“Chrome 134+ and WebGPU requirement kills a significant fraction of potential users — Safari and iOS aren't supported at all. This is research-grade code with 264 stars, not a production library. Zig as the core language also means limited community support if something breaks.”
“This is the compound interest of AI agents. Today it saves tokens; in 12 months, a mature skill graph trained on thousands of production runs will be a serious competitive moat. The shared registry model could evolve into an open marketplace for agent intelligence that rivals model weights in value.”
“Browser-native LLM inference with compressed KV-caches is the path to private, local AI that actually fits in commodity hardware. TurboQuant is solving a memory wall problem that will matter more as models get longer context windows. The ICLR 2026 backing means the math is sound.”
“Imagine a skill library that remembers how I like my scripts structured and applies it every time without me re-explaining my style. The memory layer for agents has been the missing piece, and this fills it elegantly — especially now that messaging adapters mean it works in my existing workflow tools.”
“The Excalidraw diagram demo is legitimately impressive as a creative tool — prompt to architecture diagram in seconds, no server required. But until Safari/iOS support lands, this is a power-user curiosity. Most creative workflows aren't running on Chrome 134+ with WebGPU enabled.”
