JetBrains AI Assistant brings AI chat, code generation, and agents into IntelliJ IDEA, PyCharm, WebStorm, and the rest of the JetBrains IDEs. Its bring-your-own-key support takes OpenAI-compatible custom endpoints with your own API key, no JetBrains AI subscription required. Point it at Opper's gateway and your IDE runs on any of 700+ models with one key and a choice of region.
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 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.
