Embedding Models

Models By Tier

Each tier uses a specific model optimized for that price point. No configuration needed.

all-MiniLM-L6-v2

Fast local model. Perfect for cost-effective embeddings with good quality.

384 dimensions | Script & Agent tiers

text-embedding-3-small

OpenAI's efficient embedding model. Great balance of cost and quality.

1536 dimensions | Pro tier

text-embedding-3-large

OpenAI's most capable embedding model. Best for complex retrieval.

3072 dimensions | Pro+ tier
