- Add gemini-4-argon, gemini-3.8-flash, gemini-3.6-flash, gemini-3.5-flash-lite and gemini-embedding-2. - Mark models that Google has replaced or shut down as deprecated. No model is removed. - Use gemini-embedding-001 as the default embedding model. text-embedding-004 now returns 404. Signed-off-by: Charles <azanux@gmail.com>
- Point deprecated text-embedding-004/005 to gemini-embedding-001, the default embedding model. - Test the default embedding model and the deprecated constants. - Add a live test that calls every embedding model and checks the vector size. Signed-off-by: Charles <azanux@gmail.com>

Summary
Updates the Google GenAI (Gemini) model list to match what Google offers today. Every model was checked with a real API call.
No model is removed, so existing code keeps compiling.
Changes
New models
gemini-4-argongemini-3.8-flashgemini-3.6-flashgemini-3.5-flash-litegemini-embedding-2Google has announced that 3.8 Flash and 3.6 Flash will cost $1.50 / $7.50 from January 1, 2027. The YAML file notes this.
Deprecated models
These constants are now marked
@Deprecated. Their YAML entries are kept, with a comment.GEMINI_3_5_FLASHGEMINI_3_6_FLASHGEMINI_3_FLASH_PREVIEWGEMINI_3_6_FLASHGEMINI_3_1_FLASH_LITE_PREVIEWGEMINI_3_1_FLASH_LITETEXT_EMBEDDING_004GEMINI_EMBEDDING_001TEXT_EMBEDDING_005GEMINI_EMBEDDING_001Default embedding model fixed
DEFAULT_TEXT_EMBEDDING_MODELpointed totext-embedding-004, which Google shut down. Any call to it returns 404. It now points togemini-embedding-001, which is already declared in the YAML file.Docs
The model list on the installation page now includes the new models and marks the deprecated ones.
Tests
GoogleGenAiModelLoaderTest: checks that the new models are loaded and that the default embedding model is declared in the YAML file.GoogleGenAiModelsTest(new): checks the default embedding model and that the deprecated embedding constants point toGEMINI_EMBEDDING_001.GoogleGenAiAllModelsIT: calls every declared chat model with a real API key (14/14 pass).GoogleGenAiEmbeddingIT(new): calls every embedding model and checks the vector size (3/3 pass).Closes #2157
