Editing Chuk Chat AI Providers and Services

= Chuk Chat AI Providers and Services =

This page explains which external services Chuk Chat uses and why.

== AI model routing (OpenRouter) ==
Chuk Chat uses OpenRouter to route requests to supported open-weight models and providers.

=== Why OpenRouter is used ===
* Access to multiple open-weight model families
* Flexible provider routing
* Operational resilience across providers

=== Model families commonly used ===
* Llama
* Mistral
* Qwen
* DeepSeek

== Zero Data Retention (ZDR) filtering ==
Chuk Chat filters provider choices to ZDR-compliant options so privacy requirements are enforced at routing time.

That means providers without required privacy guarantees are filtered out automatically.

== Voice and audio services ==
* '''Speech-to-text''': Groq Whisper (/v1/ai/transcribe-audio)
* '''Text-to-speech''': Inworld endpoint exists in docs but is currently disabled
* '''Realtime voice/video''': planned via LiveKit (coming soon)

== Core platform services ==
* '''Supabase''': authentication, database, and storage
* '''Stripe''': subscription checkout and billing portal
* '''Hetzner''': backend hosting infrastructure

== What each service typically receives ==
* OpenRouter/provider: prompt plus selected model parameters (for response generation)
* Groq (voice transcription): uploaded audio file for conversion to text
* Supabase: account data plus encrypted chat payloads for storage/sync
* Stripe: payment/subscription data

== Important note ==
Chuk Chat is designed so chat content is encrypted before storage. Still, users should avoid sharing highly sensitive personal or financial secrets in any AI chat workflow.
