OpenClaw is an open-source personal AI agent that goes beyond coding — a single conversational agent for everyday tasks, from research to automation. It's open-source and model-agnostic, so you're never tied to one provider's model or pricing. On Opper you can run routine work on cheaper or open-weight models and step up to a frontier model when it matters, all on one key.

Set up with agents
Paste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
GLM-5.3-Flash runs on the routes below. Route only to EU providers when your data has to stay in Europe. Some routes also sell flex and priority processing: the same model at another price, picked per request with service_tier. How service tiers work.
GLM-5.3-Flash by Z.ai is a natively multimodal 320B MoE with 18B active parameters, hybrid sparse and linear attention, a 1M-token context, and MIT open weights for coding and agent work.
