cloudflare-ai-gateway: non-OpenAI/Anthropic providers fail with 'Invalid provider'

[superhighfives]

Description

On the cloudflare-ai-gateway provider, every model that isn't OpenAI or Anthropic fails with Bad Request: Invalid provider — Google, xAI, Alibaba, DeepSeek, Moonshot.

The loader routes anything that isn't openai/, anthropic/, or workers-ai/ through ai-gateway-provider's unified (compat) route, which posts to the gateway's universal compat endpoint. That endpoint only fronts a few upstreams, so the rest come back "Invalid provider". Cloudflare's catalog-aware REST API (/accounts/{id}/ai/v1/chat/completions) does serve them.

Plugins

None.

OpenCode version

1.18.22

Steps to reproduce

1. Configure the cloudflare-ai-gateway provider (CLOUDFLARE_ACCOUNT_ID, CLOUDFLARE_API_TOKEN, CLOUDFLARE_GATEWAY_ID).
2. Run: opencode run "hello" --model cloudflare-ai-gateway/xai/grok-4.5
3. It fails with Bad Request: Invalid provider. Same for any google/*, alibaba/*, deepseek/*, moonshotai/* model. openai/* and anthropic/* work.
