Excited to share: I’m using Grok 4.5 as the model behind Claude Code.
How: SpoX — a zero-dependency Python proxy on localhost:8048.
- Grok subscription → OAuth device code (no API key) - Speaks Anthropic Messages API (and OpenAI chat completions) - Claude Code / VSCodium point ANTHROPIC_BASE_URL at it - Compact window set to 500k so it matches Grok’s real limit
Two files. stdlib only. Start it, log in once, keep building.
