Properties

Methods
ApplyCapabilityRequestProfile(AIRequestProfile)
Applies only execution-local profile settings needed to describe capabilities.
protected override void ApplyCapabilityRequestProfile(AIRequestProfile profile)Parameters
profileAIRequestProfile
Remarks
Common builder overrides are already captured. Custom providers may override this hook with SetExecutionSetting calls for native mode flags. Do not prepare execution, reserve token budgets, invoke callbacks, validate requests, or modify service/caller-owned state. Execution profile hooks are intentionally not called during inspection.
ApplyProviderSpecificRequestProfile(AIRequestProfile)
protected override Action ApplyProviderSpecificRequestProfile(AIRequestProfile profile)Parameters
profileAIRequestProfile
Returns
CaptureRequestSettings(IDictionary<string, object?>)
Captures provider and common defaults. Overrides copy native mutable option values.
protected override void CaptureRequestSettings(IDictionary<string, object?> settings)Parameters
settingsIDictionary<string, object>
CreateFunctionMessageRequest()
Creates HTTP request with function definitions
protected override HttpRequestMessage CreateFunctionMessageRequest()Returns
CreateMessageRequest()
Creates the HTTP request message for the AI service
protected override HttpRequestMessage CreateMessageRequest()Returns
CreateStreamParseFailure(string, Exception, StreamDiagnostics)
Lets providers turn a malformed SSE data event into an explicit terminal error. Returning null preserves the tolerant behavior used by legacy compatible providers.
protected override StreamingContent? CreateStreamParseFailure(string jsonData, Exception exception, StreamDiagnostics diagnostics)Parameters
jsonDatastringexceptionExceptiondiagnosticsStreamDiagnostics
Returns
ExtractFunctionCalls(string)
Extracts every function call from one API response.
protected override (string content, FunctionCallBatch functionCalls) ExtractFunctionCalls(string response)Parameters
responsestring
Returns
ExtractResponseContent(string)
Extracts the response content from the API response
protected override string ExtractResponseContent(string responseContent)Parameters
responseContentstring
Returns
GetCompletionAsync(Message)
public override Task<string> GetCompletionAsync(Message message)Parameters
messageMessage
Returns
GetInputTokenCountAsync()
Gets the token count for the current conversation
public override Task<uint> GetInputTokenCountAsync()Returns
GetInputTokenCountAsync(string)
Gets the token count for a specific prompt
public override Task<uint> GetInputTokenCountAsync(string prompt)Parameters
promptstring
Returns
GetModelMaxOutputTokens()
Returns the maximum output tokens allowed for the current model. Override in each service to provide model-specific limits.
protected override uint GetModelMaxOutputTokens()Returns
GetRunRequestedModel()
Resolves the explicit model ID sent for the captured run request.
protected override string GetRunRequestedModel()Returns
Remarks
Override when provider options replace the configured model or translate it to a wire ID. Return null when the request delegates model selection without a single model ID. Called within the captured request settings and provider-feature scope.
ParseStreamChunk(string, StreamOptions)
Parses a single SSE JSON chunk into a provider-neutral stream chunk. Each provider overrides this to handle its specific JSON format.
protected override OpenAICompatibleService.OpenAIStreamChunk ParseStreamChunk(string jsonData, StreamOptions options)Parameters
jsonDatastringoptionsStreamOptions
Returns
ResolveRequestCapabilities()
Resolves adapter support using RequestSetting and CurrentRequestFeatures without side effects.
protected override AIModelCapabilities ResolveRequestCapabilities()Returns
Remarks
Custom providers may override this hook. The default preserves compatibility by returning Unknown. Overrides must not send requests, consume options, change history or invoke user callbacks.
StreamParseJson(string)
Parses streaming JSON data
protected override string StreamParseJson(string jsonData)Parameters
jsonDatastring
Returns
UseMaxModel()
public QwenService UseMaxModel()Returns
UsePlusModel()
public QwenService UsePlusModel()Returns
UseQwen3_235BModel()
public QwenService UseQwen3_235BModel()Returns
UseQwen3_32BModel()
public QwenService UseQwen3_32BModel()Returns
UseTurboModel()
public QwenService UseTurboModel()Returns
ValidateStreamTermination(bool, bool, StreamDiagnostics)
Lets providers require an explicit successful terminal event before committing a streamed assistant message or executing a collected function call.
protected override StreamingContent? ValidateStreamTermination(bool doneMarkerReceived, bool completionEventReceived, StreamDiagnostics diagnostics)Parameters
doneMarkerReceivedboolcompletionEventReceivedbooldiagnosticsStreamDiagnostics
Returns
