Describe the enhancement you want to request
The problem: I am using the new private LLM Gateway from tailscale called Aperture and when I setup a Bedrock compatible provider opencode is asking for bedrock authentication even though its not required in this instance. Aperture is dealing with the last mile to Bedrock auth.
Claude Code has CLAUDE_CODE_SKIP_BEDROCK_AUTH which allows you to use a LLM gateway and skip the Bedrock auth check.
Config looks like this:
"provider": {
"aperture": {
"name": "tailnet aperture",
"npm": "@ai-sdk/amazon-bedrock",
"options": {
"baseURL": "http://ai.tail819a6.ts.net/bedrock"
},
"models": {
"global.anthropic.claude-sonnet-4-6": {
"name": "sonnet-4.6"
}
}
}
},I suggest an env var and/or a provider config option to skip the authentication.
something like:
OPENCODE_SKIP_BEDROCK_AUTH and provider..options.skipAuth
I am happy to raise a PR for this? Let me know!
