Copilot: https://docs.github.com/en/copilot/how-tos/copilot-cli/custo... (also worked in Visual Studio Code)

Claude Code: https://code.claude.com/docs/en/model-config (here’s an example of a custom config in the wild with DeepSeek, same principle for local connection https://api-docs.deepseek.com/guides/agent_integrations/clau...)

Cursor: couldn’t find official docs but here’s z.AI docs https://docs.z.ai/devpack/tool/cursor (same principle for local API)
