InputsPhaseUnion Type | OpenRouter Go SDK | OpenRouter

The Go SDK and docs are currently in beta. Report issues on GitHub.

The phase of an assistant message. Use commentary for an intermediate assistant message and final_answer for the final assistant message. For follow-up requests with models like gpt-5.3-codex and later, preserve and resend phase on all assistant messages. Omitting it can degrade performance. Not used for user messages.

Supported Types

InputsPhaseCommentary

1 inputsPhaseUnion := components.CreateInputsPhaseUnionInputsPhaseCommentary(components.InputsPhaseCommentary{/* values here */})

InputsPhaseFinalAnswer

1 inputsPhaseUnion := components.CreateInputsPhaseUnionInputsPhaseFinalAnswer(components.InputsPhaseFinalAnswer{/* values here */})

1 inputsPhaseUnion := components.CreateInputsPhaseUnionAny(any{/* values here */})

Union Discrimination

Use the Type field to determine which variant is active, then access the corresponding field:

1 switch inputsPhaseUnion.Type {
2 	case components.InputsPhaseUnionTypeInputsPhaseCommentary:
3 		// inputsPhaseUnion.InputsPhaseCommentary is populated
4 	case components.InputsPhaseUnionTypeInputsPhaseFinalAnswer:
5 		// inputsPhaseUnion.InputsPhaseFinalAnswer is populated
6 	case components.InputsPhaseUnionTypeAny:
7 		// inputsPhaseUnion.Any is populated
8 }
