Description

Related Issue: #1751

Add opencode_go_anthropic channel type to support Anthropic Messages API format for OpenCode Go provider, and update
existing opencode_go channel config with actual supported models.

New Channel Type: `opencode_go_anthropic`

The OpenCode Go provider now supports the Anthropic Messages API format (@ai-sdk/anthropic) alongside the existing
OpenAI-compatible format. (Note that only some models support the Anthropic Messages API
format. See https://opencode.ai/docs/zh-cn/go/#api-%E7%AB%AF%E7%82%B9)

Supported Models

Model	API Format
minimax-m3	Anthropic Messages
minimax-m2.7	Anthropic Messages
minimax-m2.5	Anthropic Messages
qwen3.7-max	Anthropic Messages
qwen3.7-plus	Anthropic Messages
qwen3.6-plus	Anthropic Messages

Updated Channel Config: `opencode_go`

baseURL: https://opencode.ai/zen/go (removed trailing /v1, added by transformer)
defaultModels: glm-5.1, glm-5, kimi-k2.5, kimi-k2.6, deepseek-v4-pro, deepseek-v4-flash, mimo-v2.5, mimo-v2.5-pro

OpenAI-Compatible Models (use `opencode_go` channel)

Model	API Format
glm-5.1	OpenAI Compatible
glm-5	OpenAI Compatible
kimi-k2.5	OpenAI Compatible
kimi-k2.6	OpenAI Compatible
deepseek-v4-pro	OpenAI Compatible
deepseek-v4-flash	OpenAI Compatible
mimo-v2.5	OpenAI Compatible
mimo-v2.5-pro	OpenAI Compatible

Technical Details

Backend

Ent schema: New opencode_go_anthropic enum value in internal/ent/schema/channel.go
channel_llm.go: Separate case using anthropic.PlatformDirect transformer, following bailian_anthropic pattern
Generated files: Migration schema, GraphQL enum, internal schema updated

Frontend

config_channels.ts: New channel config with Anthropic API format, updated opencode_go config
config_providers.ts: opencode_go provider now lists both channel types
schema.ts: Zod enum updated
i18n: Display name OpenCode Go (Anthropic) in English and Chinese

Files Changed

File	Description
`internal/ent/schema/channel.go`	Add enum value
`internal/ent/channel/channel.go`	Add type constant and validator
`internal/server/biz/channel_llm.go`	Add PlatformDirect transformer case
`internal/server/gql/ent.graphql`	GraphQL enum
`internal/ent/internal/schema.go`	Generated schema
`internal/ent/migrate/schema.go`	Migration schema
`frontend/src/features/channels/data/config_channels.ts`	Channel configs
`frontend/src/features/channels/data/config_providers.ts`	Provider mapping
`frontend/src/features/channels/data/schema.ts`	Zod schema
`frontend/src/locales/en/channels.json`	English i18n
`frontend/src/locales/zh-CN/channels.json`	Chinese i18n

Testing

Verified against live OpenCode Go API with PostgresSQL backend:

Non-streaming message (qwen3.5-plus): Correctly returns thinking + tool_use blocks
Streaming message (qwen3.5-plus): Complete SSE events (message_start → content_block_start thinking →
content_block_delta → tool_use → message_stop)
Tool calling: Bash tool call parameters are passed correctly
Multiple models: qwen3.5-plus,qwen3.6-plus, minimax-m3 all work correctly
Lint: ESLint + go vet passes

Notes

Some models (e.g., deepseek-v4-flash) are routed to DeepSeek backend by OpenCode Go gateway, which expects OpenAI
tool format. These should use opencode_go channel type instead.
The opencode_go_anthropic channel type is intended for models that natively support Anthropic Messages API format.

Greptile Summary

This PR adds an opencode_go_anthropic channel type to support the Anthropic Messages API format for OpenCode Go, and updates the existing opencode_go channel with accurate default models and a corrected base URL. The implementation follows the established pattern used by bailian_anthropic and other Anthropic-variant channels throughout the codebase.

Backend: New TypeOpencodeGoAnthropic constant, validator entry, GraphQL enum value, and a channel_llm.go case using anthropic.PlatformDirect — all consistent with prior Anthropic-variant additions. Generated Ent files updated accordingly; no separate SQL migration is needed as the project relies on Ent auto-migration for enum additions.
Frontend: New opencode_go_anthropic channel config using ANTHROPIC_MESSAGES format, added to the opencode_go provider's channelTypes, Zod enum, and both EN/ZH-CN i18n files. The head commit (955bab67) also removes the dead opencode_go_anthropic entry that was mistakenly included in the Provider union type.

Confidence Score: 5/5

Safe to merge — the change is an additive, well-scoped new channel variant following an established pattern, with no modifications to shared logic.

All changes are additive: a new enum value, a new switch case, a new frontend config entry, and updated i18n. No existing behaviour is modified except the opencode_go default model list and base URL, which only affect newly created channels. The dead Provider union member flagged in review was already removed in the head commit. The backend transformer path for opencode_go_anthropic is identical in structure to the existing bailian_anthropic/moonshot_coding path and carries no new risk.

No files require special attention.

Important Files Changed

Filename	Overview
internal/ent/schema/channel.go	Adds opencode_go_anthropic to the Ent schema enum, consistent with all other Anthropic-variant channel additions.
internal/ent/channel/channel.go	Adds TypeOpencodeGoAnthropic constant and includes it in the TypeValidator switch — matches the established pattern for every other channel type.
internal/server/biz/channel_llm.go	Adds a new TypeOpencodeGoAnthropic case using anthropic.PlatformDirect transformer, identical in behaviour to the existing TypeBailianAnthropic/TypeMoonshotCoding case; a previously-flagged suggestion to consolidate these into one case is outstanding.
internal/server/gql/ent.graphql	GraphQL ChannelType enum updated with opencode_go_anthropic — straightforward, no issues.
frontend/src/features/channels/data/config_channels.ts	Adds opencode_go_anthropic channel config with correct ANTHROPIC_MESSAGES API format; updates opencode_go defaultModels and baseURL (trailing /v1 removed, added by transformer); dead opencode_go_anthropic member removed from Provider union in the head commit.
frontend/src/features/channels/data/config_providers.ts	Adds opencode_go_anthropic to the opencode_go provider's channelTypes array — correct.
frontend/src/features/channels/data/schema.ts	Zod channelTypeSchema enum updated with opencode_go_anthropic — no issues.
frontend/src/locales/en/channels.json	Adds channels.types.opencode_go_anthropic i18n key in English.
frontend/src/locales/zh-CN/channels.json	Adds channels.types.opencode_go_anthropic i18n key in Chinese.
