credentials. When credentials supplies an api_key or sa_key, use only its auth
fields; for an SA key, resolve project_id from the credential row or parsed

covering BYOK api_key with platform SA credentials and BYOK sa_key with a
platform project ID.

We can directly annotate the variable as interaction: Interaction = self.client.interactions.create(...) instead of using cast(). This keeps the type annotation simple and avoids an unnecessary cast().

Since this interaction creation logic is duplicated throughout the file, can we create a single reusable function that accepts parameters like type, adjusts the input structure accordingly, and returns the Interaction object? What do you think?

yes I was of the same opinion. Not sure why Claude prefers cast. Will update that. Thakns for flagging it

🌐 Web query:
official Vertex AI Gemini Interactions API supported models Gemini 2.5 thinking_level
💡 Result:
**Short answer:** The official Interactions API docs list `gemini-2.5-pro`, `gemini-2.5-flash`, and `gemini-2.5-flash-lite`; the thinking guide says all three support `thinking_level` values `low`, `medium`, and `high`. ([ai.google.dev](https://ai.google.dev/api/interactions-api?authuser=5&hl=en&utm_source=openai))
However, those pages describe the **Gemini API**, not Vertex AI. I couldn’t verify from the official Vertex AI sources that the Interactions API endpoint is supported on Vertex AI, so don’t assume that model support or the `thinking_level` parameter carries over to Vertex AI. The closest Vertex AI source confirms those Gemini 2.5 models are available there, but does not establish Interactions API support. ([cloud.google.com](https://cloud.google.com/vertex-ai/generative-ai/docs/learn/models?authuser=5&utm_source=openai))

🌐 Web query:
site:cloud.google.com/vertex-ai "Interactions API" "Gemini 2.5" supported not supported
💡 Result:
Google Cloud’s model pages list the **Interactions API as not supported** for Gemini 2.5 models, including **Gemini 2.5 Pro, Flash, and Flash-Lite**. ([docs.cloud.google.com](https://docs.cloud.google.com/gemini-enterprise-agent-platform/models/gemini/2-5-pro?utm_source=openai))
So, according to those pages, Gemini 2.5 models aren’t available through the Interactions API; the pages list the GenerateContent API as supported. ([docs.cloud.google.com](https://docs.cloud.google.com/gemini-enterprise-agent-platform/models/gemini/2-5-pro?utm_source=openai))

Do not send gemini-2.5-pro through Vertex Interactions API.
GoogleGCPProvider._execute_stt defaults to gemini-2.5-pro and passes it to self.client.genai.interactions.create(...). Google Cloud lists the Interactions API as unsupported for Gemini 2.5 Pro. The default GCP text and TTS models are different, so this issue is specific to the 2.5 model path.
Route Gemini 2.5 models through models.generate_content, or change the GCP STT default to a Vertex model that supports the Interactions API. Omitting thinking_level alone does not resolve the unsupported API call.

official Google Vertex AI Gemini Interactions API text to speech gemini-3.8-flash-tts response_format audio speech_config
💡 Result:
For **Gemini Interactions API TTS**, use `response_format: {"type": "audio"}` and put `speech_config` inside `generation_config`. Example REST request:
```bash
curl -X POST "https://generativelanguage.googleapis.com/v1beta/interactions" \
-H "x-goog-api-key: $GEMINI_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "gemini-3.8-flash-tts",
"input": [{
"type": "user_input",
"content": [{
"type": "text",
"text": "Have a wonderful day!",
"annotations": [{
"type": "speech_metadata",
"style": "cheerful and friendly"
}]
}]
}],
"response_format": {"type": "audio"},
"generation_config": {
"speech_config": [{"voice": "Kore"}]
}
}'
```
This is the **Gemini API** endpoint (`generativelanguage.googleapis.com`), not a Vertex AI endpoint. The official example shows the same fields and says to retrieve generated audio from `interaction.output_audio.data`. For a unary request, WAV is the default; set `response_format.mime_type` to `audio/l16`, `audio/mulaw`, or `audio/alaw` if you need another format. ([ai.google.dev](https://ai.google.dev/gemini-api/docs/speech-generation?authuser=7&utm_source=openai))
The Vertex AI reference documents `SpeechConfig` for speech generation, but the cited Interactions example does not establish that this exact model and Interactions request are available through Vertex AI.

The model page lists “Interactions API preview” as unsupported; it’s a Preview model available in the global region. ([docs.cloud.google.com](https://docs.cloud.google.com/gemini-enterprise-agent-platform/models/gemini/3-8-flash-tts?hl=en&utm_source=openai))
The Gemini TTS overview also describes Gemini 3.8 TTS as available through the Gemini Enterprise API, rather than the Cloud Text-to-Speech API. ([docs.cloud.google.com](https://docs.cloud.google.com/gemini-enterprise-agent-platform/models/text-to-speech/overview?hl=en&utm_source=openai))

Route Vertex TTS through models.generate_content.
gemini-3.8-flash-tts does not support the Interactions API on Vertex AI. The default GCP TTS path therefore can fail before audio generation. Use client.models.generate_content with Vertex's response_modalities=["AUDIO"] request shape instead of client.interactions.create.

Update the default GCP TTS path in GoogleAIProvider to use
client.models.generate_content instead of GoogleAIProvider.create_interaction,
which calls the unsupported Interactions API on Vertex AI. Pass the request
using Vertex’s response_modalities=["AUDIO"] shape while preserving the existing
model, transcript, and speech configuration.
