Zed is a high-performance, open-source code editor from Zed Industries, the team that created Atom, written from scratch in Rust with AI and collaboration built in. Its agent panel works with any OpenAI-compatible provider you add, and API keys stay in your system keychain. Add Opper as a provider and Zed's agent runs on any of 700+ models, with a choice of EU or US hosting 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.
