I love the interface of Claude Code but with these limits I’d be willing to use Codex. Anyone know if it’s possible to use Claude Code with other provider subscriptions (not API usage costs)?

You can!

According to the GLM documentation at least, you can edit you .env (~/.claude/settings.json) with an API key from the GLM Settings page. [0].

{ "env": { "ANTHROPIC_AUTH_TOKEN": "your_zai_api_key", "ANTHROPIC_BASE_URL": "https://api.z.ai/api/anthropic", "API_TIMEOUT_MS": "3000000" } }

Whilst you need to generate an API Key, you are still using the 'GLM Coding Plan' as per 'Methods for Using the GLM Coding Plan in Claude Code' documentation.

Yes, I've run Claude Code using ollama running on my GPU server with a 5090.
