MetaClaw v0.4.0 agent framework released
MetaClaw v0.4.0 dropped as an evolving agent framework with co-evolving skills and memory—it's tuned for CLI benchmarks and runs without a GPU, making it great for hands-on ML pipeline experiments. The release is a neat option for students building agentic prototypes without costly infra. (x.com)
AIMING Lab’s MetaClaw repository shows a recent commit labeled “feat: v0.4.0 Contexture layer — memory system, benchmark, extensions” authored by contributors richard-peng-xia and claude in the openclaw-metaclaw-memory tree. (github.com/aiming-lab/MetaClaw/tree/main/openclaw-metaclaw-memory) The memory component’s source declares “Self‑evolving local‑first memory with hybrid retrieval, 6 structured types, and adaptive policy,” and registers tools and slash commands for recall, capture, and memory status in the plugin’s index file. (github.com/aiming-lab/MetaClaw/blob/main/openclaw-metaclaw-memory/src/index.ts) The accompanying technical report evaluated MetaClaw on MetaClaw‑Bench (934 questions over 44 simulated workdays) and recorded Kimi‑K2.5 accuracy improving from 21.4% to 40.6%, with a GPT‑5.2 baseline at 41.1% and an 8.25× increase in end‑to‑end task completion. (arxiv.org/abs/2603.17187) The README and architecture notes state MetaClaw uses a proxy architecture and offloads LoRA fine‑tuning to a Tinker cloud service, enabling deployments “without a local GPU” while running Kimi‑2.5 (~200B MoE) by default and offering Qwen3‑4B as a lightweight alternative. (github.com/aiming-lab/MetaClaw/blob/main/README.md) The CLI surface documented in the repo includes one‑line setup and daemon commands such as “metaclaw setup” and “metaclaw start” (default “madmax” mode), and the memory plugin exposes slash commands like /remember, /recall and /memory‑status plus CLI utilities for search and wipe. (github.com/aiming-lab/MetaClaw/blob/main/README.md) Files under dist and src for the openclaw‑metaclaw‑memory package show the v0.4.0 changes present in both compiled and source directories with commit timestamps inside the last 24 hours on the main branch.
