feat: Add Berget AI support with automatic API provider selection by irony · Pull Request #1 · oloflarsson/TalkToEvroc

irony · 2026-01-28T18:04:10Z

Summary

Adds support for Berget AI alongside the existing Evroc API, with automatic provider detection based on which API key is configured.

Changes

Core Functionality

Dual API support: Add BERGET_API_KEY alongside EVROC_API_KEY
Automatic provider selection: Bot detects which API key is set and configures the corresponding base URL:
- Berget AI: https://api.berget.ai/v1
- Evroc: https://models.think.cloud.evroc.com/v1
Dynamic system prompt: Bot personality updates based on active provider

Code Changes

main.py: Refactored API configuration to support both providers
piper-start.sh: Fixed locale issue with decimal separators (LC_ALL=C)
.gitignore: Added .env to prevent accidental API key commits

Documentation

Updated README.md and AGENTS.md with dual API setup instructions
Clear guidance on which provider to use (Berget AI preferred)

Swedish Pronunciation

Added pronunciation fix: "Berget" → "bärjett"
Updated Whisper prompt to recognize "Berget AI"

Usage

# Preferred: Berget AI
export BERGET_API_KEY="sk_ber_..."

# OR: Legacy Evroc
export EVROC_API_KEY="..."

The bot automatically uses whichever API key is configured. Both providers support the same models:

STT: KBLab/kb-whisper-large
LLM: openai/gpt-oss-120b

Testing

✅ Tested with Berget AI API - voice conversation working correctly
✅ Swedish STT (Whisper) transcribing accurately
✅ LLM responding with Berget AI context
✅ TTS with Swedish pronunciation fixes

- Add BERGET_API_KEY support alongside existing EVROC_API_KEY - Automatically detect and use whichever API key is configured - Update system prompt to dynamically reference the active provider - Add Swedish pronunciation fix for "Berget" → "bärjett" - Update documentation to reflect dual API support - Fix Piper TTS locale issue with decimal separators (LC_ALL=C) - Add .env to .gitignore to prevent API key leaks Users can now use either Berget AI (api.berget.ai/v1) or Evroc (models.think.cloud.evroc.com/v1) by setting the corresponding environment variable. Both providers support the same models: - STT: KBLab/kb-whisper-large - LLM: openai/gpt-oss-120b

The description states the demo is "built with Berget AI cloud services" but the code supports both Berget AI and Evroc. This creates misleading documentation that doesn't reflect the dual-provider capability being added in this PR.

+Set **either** `BERGET_API_KEY` or `EVROC_API_KEY`:
+
 ```bash
-export EVROC_API_KEY="your-api-key"
+export BERGET_API_KEY="your-api-key"  # Preferred - Berget AI
+# OR
+export EVROC_API_KEY="your-api-key"   # Legacy - Evroc
 ```


The prerequisites section still states "Evroc API keys for STT and LLM services" but should be updated to reflect that either Berget AI or Evroc API keys are needed, consistent with the new dual-provider support.

+# Determine which API to use based on available API key
+if BERGET_API_KEY:
+    API_KEY = BERGET_API_KEY
+    BASE_URL = "https://api.berget.ai/v1"
+    API_PROVIDER = "Berget AI"

+    API_KEY = EVROC_API_KEY
+    BASE_URL = "https://models.think.cloud.evroc.com/v1"
+    API_PROVIDER = "Evroc"


When both BERGET_API_KEY and EVROC_API_KEY are set, the code silently prioritizes Berget AI without warning the user. Consider logging which provider is being used, or documenting this priority behavior clearly in the code comments and documentation to avoid confusion.

Suggested change

# Determine which API to use based on available API key

if BERGET_API_KEY:

API_KEY = BERGET_API_KEY

BASE_URL = "https://api.berget.ai/v1"

API_PROVIDER = "Berget AI"

elif EVROC_API_KEY:

API_KEY = EVROC_API_KEY

BASE_URL = "https://models.think.cloud.evroc.com/v1"

API_PROVIDER = "Evroc"

# Determine which API to use based on available API key.

# Note: If both BERGET_API_KEY and EVROC_API_KEY are set, Berget AI is used.

if BERGET_API_KEY:

if EVROC_API_KEY:

logger.warning(

"Both BERGET_API_KEY and EVROC_API_KEY are set; defaulting to Berget AI."

)

API_KEY = BERGET_API_KEY

BASE_URL = "https://api.berget.ai/v1"

API_PROVIDER = "Berget AI"

logger.info(f"Using API provider: {API_PROVIDER}")

elif EVROC_API_KEY:

API_KEY = EVROC_API_KEY

BASE_URL = "https://models.think.cloud.evroc.com/v1"

API_PROVIDER = "Evroc"

+    API_PROVIDER = "Evroc"
+else:
+    raise ValueError("Either BERGET_API_KEY or EVROC_API_KEY must be set")


The error message could be more helpful by indicating where these environment variables should be set and providing an example. Consider expanding it to guide users on the next steps, for example: "Either BERGET_API_KEY or EVROC_API_KEY must be set as an environment variable. Example: export BERGET_API_KEY='your-key-here'"

Suggested change

raise ValueError("Either BERGET_API_KEY or EVROC_API_KEY must be set")

raise ValueError(

"Either BERGET_API_KEY or EVROC_API_KEY must be set as an environment variable. "

"Example (bash): export BERGET_API_KEY='your-key-here'"

)

+OM BERGET AI:
+- En svensk AI-plattform för utvecklare och företag.
+- Fokus på öppna AI-modeller och europeisk datasuveränitet.
 - All data inom EU med full GDPR-efterlevnad.
- Fokus på hållbarhet och förnybar energi.
- Mål: 10 hyperscale-datacenter till 2030.
-
-EVROCS TJÄNSTER:
- Cloud: Compute, Storage, Kubernetes, Serverless, IAM, Databaser.
- AI: NVIDIA B200 och H100 GPU-kluster, Think Studio, Think Models.
-
-VARFÖR EVROC:
- Europeisk datasuveränitet, inte utländska lagar.
- Över 80 procent av Europas molnmarknad är utländsk, Evroc ändrar det.
+- Tillhandahåller både LLM- och STT-tjänster via OpenAI-kompatibelt API.


The system prompt contains hardcoded information about "BERGET AI" (lines 155-159) that will be included regardless of which API provider is selected. When using Evroc, this section will incorrectly describe Berget AI instead of Evroc. The prompt should conditionally include provider-specific information based on the selected API_PROVIDER.

+"""TalkToBerget Voice Bot - Swedish chatbot using Berget AI services.

 A Pipecat voice bot using:
- STT: Evroc KBLab Whisper (Swedish)
- LLM: Evroc GPT-OSS-120B
+- STT: Berget AI Whisper (Swedish)
+- LLM: Berget AI GPT-OSS-120B


The module docstring hardcodes "Berget AI services" in the description, but the code now supports both Berget AI and Evroc. The docstring should reflect that the bot can use either provider, not just Berget AI.

The title has been changed to "TalkToBerget" but the live demo URL still points to "talktoevroc.olof.tech", creating a naming inconsistency. Either the title should remain more generic or the URL reference should be updated to match.
