Latest Sandbox Image 0.7.8 doesn't work when trying to use opencode with CF AI Gateway

[orionstudt]

See here: anomalyco/opencode#13758 (comment)

I confirmed with opencode --version the image is running opencode 1.2.15.

I am configured with Cloudflare AI Gateway and trying to use cloudflare-ai-gateway/anthropic/claude-sonnet-4-6.

Logs from opencode:

For additional context I'm using the official cloudflare sandbox image 0.7.8: https://hub.docker.com/layers/cloudflare/sandbox/0.7.8-opencode/images/sha256-ec3f866fc3bb3b2e12f789498b191afc1789371f06abb54f73d01da5bc91e20b

This comment is pointing at CF AI Gateway Provider code so I figured I'd open an issue here too.

Hi - any acknowledgement of this issue? OpenCode still does not work with CF AI Gateway because of this.

just saw this. I'll try to get eyes on this.

Thanks! I tested yesterday with the latest version of OpenCode and confirmed it is still an issue

Simplest test is just:

opencode run "What is Cloudflare?" -m cloudflare-ai-gateway/any-model

Just tested this today. You have to follow the instruction to the teeth. You need to specify:

• export CLOUDFLARE_ACCOUNT_ID=your-32-character-account-id
• export CLOUDFLARE_GATEWAY_ID=your-gateway-id

Both are required. Then you can auth login into the AI Gateway. I tried kimi k2.5 and it works out of box. For any things that requires additional api keys, such as anthropic models, it will prompt error correctly. I tried on opencode v1.3.0 on Debian Trixie. I did have to create a dedicated AI gateway, which let me specify the gateway ID.
