Unported Provider Logic Checklist

This tracks legacy provider behavior from packages/opencode/src/provider/provider.ts that still needs to be ported into the v2 provider plugins under packages/opencode/src/v2/plugin/provider/. Keep entries checked only when v2 has equivalent behavior or when the item is intentionally skipped.

Provider Setup

• Cloudflare AI Gateway custom SDK construction with createAiGateway / createUnified.
• Google Vertex authenticated fetch injection.
• Amazon Bedrock AWS credential chain setup.
• Amazon Bedrock bearer token setup.
• SAP AI Core service key setup.

Provider Options

• Azure resource name resolution.
• Azure missing-resource error.
• Azure Cognitive Services baseURL resolution.
• Cloudflare Workers AI account ID validation.
• Cloudflare Workers AI account ID vars.
• Cloudflare AI Gateway account ID validation.
• Cloudflare AI Gateway gateway ID validation.
• Cloudflare AI Gateway token validation.
• Amazon Bedrock region precedence.
• Amazon Bedrock profile precedence.
• Amazon Bedrock endpoint precedence.
• Google Vertex project resolution.
• Google Vertex location resolution.
• GitLab instance URL resolution.
• GitLab token resolution.
• GitLab AI gateway headers.
• GitLab feature flags.
• Opencode unauthenticated paid-model filtering.
• Opencode public API key fallback.

Request Behavior

• Request timeout handling.
• Chunk timeout handling.
• SSE timeout wrapping.
• OpenAI response item ID stripping.
• Azure response item ID stripping.
• OpenAI-compatible includeUsage defaulting.

Dynamic Models

• GitLab workflow model discovery.

Model Filtering

• Experimental alpha model filtering.
• Deprecated model filtering.
• Config whitelist filtering.
• Config blacklist filtering.
• gpt-5-chat-latest filtering.
• OpenRouter openai/gpt-5-chat filtering.

Default Models

• Configured default model selection. Replaced by explicit Catalog.model.setDefault.
• [SKIP] Recent-history default model selection — not porting to server-side v2 catalog.
• Default model fallback sorting. Uses newest available model, not legacy hard-coded priority.

Small Models

• [SKIP] Configured small_model selection — not porting config-driven selection to server-side v2 catalog.
• Provider-specific small model priority. Replaced by cheapest output cost selection.
• Opencode small model priority. Replaced by cheapest output cost selection.
• GitHub Copilot small model priority. Replaced by cheapest output cost selection.
• Amazon Bedrock region-aware small model selection. Replaced by cheapest output cost selection.

URL And Env Vars

• [SKIP] BaseURL ${VAR} interpolation — not porting generic URL templating; provider plugins should construct concrete URLs.
• Azure AZURE_RESOURCE_NAME vars. Handled by Azure provider plugins.
• Google Vertex vars. Handled by Google Vertex provider plugins.
• Cloudflare Workers AI vars. Handled by Cloudflare Workers AI provider plugin.

Auth

• Auth-derived provider API keys.
• OpenAI OAuth/API auth distinction.
• GitLab OAuth token selection.
• GitLab API token selection.
• Azure auth metadata resource name.
• Cloudflare auth metadata account ID.
• Cloudflare auth metadata gateway ID.

Config And Plugin Parity

• Legacy plugin auth loader behavior.
• Config provider merge behavior.
• Config model merge behavior.
• Variant generation from model metadata.
• Config variant merge behavior.
• Config variant disable behavior.
