Protected_Protected property to store additional provider-specific settings
Protected_ProtectedthinkingState tracking for streaming thinking extraction Providers should initialize this if they support thinking models
Get the current additional settings
ProtectedapiOnly sub-classes can access the API key
Read only getter method to get the Gemini client instance Note: This is async now because the client may not be initialized yet
Whether this LLM provider supports assistant prefill (pre-seeding the start of the model's response). Providers that support prefill should override this to return true. This is used as a code-level default when database metadata (AIModelType/AIModel/AIModelVendor.SupportsPrefill) is null. Database values of true/false override this getter.
Gemini supports streaming
ProtectedaddAdd thinking content to a chat completion message
OptionalthinkingContent: stringProcess a chat completion request. If streaming is enabled and supported, this will route to the streaming implementation.
Process multiple chat completion requests in parallel. This is useful for:
Array of chat completion parameter objects
Optionalcallbacks: ParallelChatCompletionsCallbacksOptional callbacks for progress and individual completions
Promise resolving to an array of ChatResults in the same order as the input params
Clear all additional settings This is useful for resetting the state of the provider or when switching between different configurations.
ProtectedcreateFactory method to create the GoogleGenAI client instance Subclasses can override this to provide custom configuration
Promise that resolves to a configured GoogleGenAI client
ProtectedcreateProtectedextractExtract thinking content from non-streaming content This method handles case-insensitive extraction of thinking blocks
ProtectedfinalizeCreate the final response from streaming results for Gemini
ProtectedflushReturns (and clears) any user-visible content the thinking-tag stripper is still holding back at
the end of a stream. Mid-stream, processStreamChunkWithThinking holds back a trailing
fragment that could be the start of a <think>/</think> tag so a split tag never leaks as
partial text; once the stream ends, such a fragment is real content and must be emitted (bug A5).
Only flushes when NOT inside a thinking block: an unterminated <think> block's buffered text is
reasoning, not answer, and is left held back (never surfaced as visible content). Returns ''
when thinking extraction isn't active (no state) or there's nothing to flush.
ProtectedgeminiGemini supports a wide range of file types natively, including via the Files API.
ProtectedgetGet the thinking tag format for this provider Providers can override this to customize the thinking tag format
ProtectedhandleTemplate method for handling streaming chat completion This implements the common pattern across providers while delegating provider-specific logic to abstract methods.
ProtectedinitializeInitialize thinking stream state for streaming extraction
ProtectednonImplementation of non-streaming chat completion for Gemini
ProtectedprocessProcess streaming chunk with thinking extraction This method handles case-insensitive extraction across chunk boundaries
ProtectedprocessProcess a streaming chunk from Gemini
ProtectedresetReset streaming state for a new request
ProtectedresetReset thinking stream state
Set additional provider-specific settings Subclasses should override this method to validate required settings
Provider-specific settings
ProtectedsupportsCheck if the provider supports thinking models Providers should override this to return true if they support thinking extraction

Base class for all LLM sub-class implementations. Not all sub-classes will support all methods. If a method is not supported an exception will be thrown.
