When to use EmbeddingGemma 300M
Where this model earns its cost — and where it doesn't.
Google’s EmbeddingGemma 300M generates 768-dimension text embeddings from a compact 300M-parameter architecture. It is designed specifically for bulk corpus indexing, semantic deduplication, and retrieval-augmented generation pipelines where cost efficiency and throughput matter more than maximum representational depth.
On Kyma, the model runs through an OpenAI-compatible endpoint with automatic request failover and exact cost reporting in the usage object. Prompt caching does not apply to embeddings: every input token bills at the input rate.
The model accepts text input up to a 2048-token context window and outputs fixed-length vectors. It does not support text generation, reasoning, vision, or structured outputs, and it is strictly an embedding-only endpoint.
Bulk Document Indexing
Index large text corporas efficiently while keeping per-token embedding costs minimal.
Budget RAG Retrieval
Power semantic search in retrieval pipelines where high throughput outweighs the need for larger vector dimensions.
Semantic Text Deduplication
Identify and remove duplicate or near-duplicate entries across large datasets using fast vector similarity.
High-Volume Data Processing
Process massive text batches quickly with a lightweight model optimized for speed and low latency.
Not ideal for: Do not use this model for documents exceeding 2048 tokens, tasks requiring generative text or reasoning, or applications that demand high-dimensional embeddings for fine-grained semantic discrimination.
