AI Setup

LearnHouse includes AI-powered features for learning assistance and content editing. The AI layer is provider-agnostic — point it at any major LLM provider by setting a provider name and an API key. These features are optional and disabled by default.

Under the hood LearnHouse uses Pydantic AI for generation, and llama-index with pgvector for RAG (Retrieval-Augmented Generation), enabling AI assistants to answer questions using your course content as context.

Supported providers

Google Gemini

OpenAI

openai

Anthropic

anthropic

DeepSeek

Moonshot (Kimi)

moonshot

Mistral

mistral

OpenRouter

AWS Bedrock

Ollama (local)

ollama

Any OpenAI-compatible endpoint (Azure OpenAI, Together, local servers, …) also works via provider: openai plus a custom base_url.

Enabling AI

Set the provider, an API key, and the feature flag in your .env file:

LEARNHOUSE_IS_AI_ENABLED=true
LEARNHOUSE_AI_PROVIDER=google           # google | openai | anthropic | deepseek | moonshot | mistral | openrouter | bedrock | ollama
LEARNHOUSE_AI_API_KEY=your-api-key      # the single key, whatever the provider

After updating your .env file, restart your instance:

learnhouse stop
learnhouse start

Upgrading from a Gemini-only setup. No config changes are required: if you only set LEARNHOUSE_GEMINI_API_KEY, provider defaults to google and that key is used automatically (for generation and embeddings). The one difference is that the default models are now the Gemini 3 family (gemini-3.5-flash, gemini-3.1-flash-lite, gemini-3.1-pro-preview) rather than Gemini 2.5 — so your key/project must have Gemini 3 access (the Pro tier uses a preview model). To stay on the previous models, pin them explicitly:

LEARNHOUSE_AI_MODEL_FAST=gemini-2.0-flash-lite
LEARNHOUSE_AI_MODEL_STANDARD=gemini-2.5-flash
LEARNHOUSE_AI_MODEL_PRO=gemini-2.5-pro

AI usage is billed directly by your chosen provider based on the models and volume used.

DeepSeek’s OpenAI-compatible endpoint is auto-configured — just set the key.

LEARNHOUSE_AI_MODEL_STANDARD=deepseek-chat

Moonshot AI (Kimi) — endpoint auto-configured.

LEARNHOUSE_AI_MODEL_STANDARD=kimi-k2-0905-preview

Other Chinese models (Alibaba Qwen, Zhipu GLM) expose OpenAI-compatible APIs — use provider: openai with their base_url, e.g. https://dashscope-intl.aliyuncs.com/compatible-mode/v1.

LEARNHOUSE_AI_MODEL_STANDARD=mistral-large-latest

OpenRouter’s base URL is configured automatically; just use OpenRouter model slugs (vendor/model) — one key gives access to hundreds of models.

LEARNHOUSE_AI_PROVIDER=openrouter
LEARNHOUSE_AI_API_KEY=sk-or-...
LEARNHOUSE_AI_MODEL_STANDARD=anthropic/claude-sonnet-4-5
LEARNHOUSE_AI_MODEL_FAST=openai/gpt-4o-mini

Bedrock uses the standard AWS credential chain (env vars, IAM role, or ~/.aws profile) plus a region — no LEARNHOUSE_AI_API_KEY is required. Use Bedrock model IDs.

LEARNHOUSE_AI_PROVIDER=bedrock
LEARNHOUSE_AI_MODEL_STANDARD=anthropic.claude-sonnet-4-5-20250929-v1:0
# AWS credentials & region via the standard AWS environment:
AWS_REGION=us-east-1

AWS_SECRET_ACCESS_KEY=...

Run any model locally with Ollama (ollama serve) — no API key needed.

LEARNHOUSE_AI_PROVIDER=ollama
LEARNHOUSE_AI_BASE_URL=http://localhost:11434/v1
LEARNHOUSE_AI_MODEL_STANDARD=qwen2.5:3b

Models & tiers

LearnHouse maps features to three model tiers. Leave them unset to use the built-in Gemini 3 defaults, or override any of them with a model name valid for your provider.

Env variable	Used for	Default (Gemini 3)
`LEARNHOUSE_AI_MODEL_FAST`	Chat titles, follow-up suggestions, course migration	`gemini-3.1-flash-lite`
`LEARNHOUSE_AI_MODEL_STANDARD`	Activity chat, RAG answers, and course planning / MagicBlocks / boards / playgrounds on free & standard plans	`gemini-3.5-flash`
`LEARNHOUSE_AI_MODEL_PRO`	Course planning / MagicBlocks / boards / playgrounds on Pro+ plans	`gemini-3.1-pro-preview`

RAG embeddings

Retrieval-Augmented Generation (course Q&A grounded in your content) needs an embedding model. By default embeddings follow your chosen provider, using a sensible default embedding model:

Provider	Default embedding model
Google	`gemini-embedding-001`
OpenAI (and Azure / Together / OpenAI-compatible)	`text-embedding-3-small`
Ollama (local)	`nomic-embed-text`

Override the embedding provider/model independently of generation if you like:

LEARNHOUSE_AI_EMBEDDING_PROVIDER=openai          # default: same as LEARNHOUSE_AI_PROVIDER
LEARNHOUSE_AI_EMBEDDING_MODEL=text-embedding-3-large
LEARNHOUSE_AI_EMBEDDING_DIMENSIONS=768           # default: 768

Two constraints to know:

Dimensions are pinned to 768 to match the pgvector column. The defaults above all produce 768-dim vectors. If you set LEARNHOUSE_AI_EMBEDDING_DIMENSIONS to another value (or use a model with a fixed, different size), you must migrate the course_embedding column and re-index existing courses.
Some providers have no embeddings API — Anthropic, DeepSeek, Moonshot, Mistral, OpenRouter, and Bedrock. With one of those selected for generation, embeddings automatically fall back to Google when LEARNHOUSE_GEMINI_API_KEY is set; otherwise set LEARNHOUSE_AI_EMBEDDING_PROVIDER to google, openai, or ollama.

Non-RAG features (activity chat, course planning, MagicBlocks, the editor assistant) don’t need embeddings and work on any provider.

File & video context (course planning)

Course planning can take images, PDFs, and YouTube links as reference material. LearnHouse converts each attachment into the right format for your provider; what actually works depends on the provider’s own capabilities:

Attachment	Google Gemini	OpenAI	Anthropic (Claude)	DeepSeek / Mistral / others
Images	✅	✅	✅	✅ on vision models
PDFs	✅	✅ (document-capable models)	✅	⚠️ model-dependent
YouTube URLs	✅	❌	❌	❌

Images and PDFs are widely supported across vision/document-capable models. YouTube links are a Gemini-only capability — Gemini fetches the video directly, while other providers have no equivalent. When an attachment type isn’t supported, the request fails with a clear error rather than silently dropping it — so if you rely on YouTube course context, keep provider: google.

Per-organization AI configuration

Once AI is enabled on the instance, each organization can toggle AI on or off and set usage limits from its admin settings. The provider and API key are set once at deployment and shared across organizations.

Usage limits

You can configure a per-organization request limit to control API costs. When a user exceeds the limit, further AI requests are rejected until the window resets.
