Cursor is the AI-native code editor from Anysphere, built on top of VS Code. It brings inline edits, codebase-aware chat, and agentic multi-file changes into the editor, and it lets you bring your own model by overriding its OpenAI base URL. Point that base URL at Opper's compatible gateway and you can drive Cursor with any model in the catalogue, with a choice of region and zero data retention.

Connect Cursor to GLM-5.3-Flash
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.
