|
|
|
ChatCompletionChunk fully implemented with ChunkChoice, ChunkDelta, ChunkToolCall, ChunkFunctionCall.
|
|
|
|
## Responses API
|
|
|
|
Basic types implemented (ResponsesRequest, ResponsesResponse, ResponsesUsage) for potential future use. Not actively used in translation since we target Chat Completions.
|
|
|
|
## Error Types
|
|
|
|
ErrorResponse with ErrorDetail (message, type, param, code) implemented.
|
|
|
|
## Known Gaps
|
|
|
|
- Responses API not used as backend target (Chat Completions only)
|
|
- WebSocket mode not supported
|
|
- Structured outputs (response_format) not translated from Anthropic
|
|
- MCP tools not supported
|
|
- Realtime API not supported
