Multimodal RAG under 500ms

Serve grounded answers over text, image, and tabular data within 500ms using optimized retrieval, caching, and model routing.

Sub-500ms multimodal RAG requires fast multimodal embeddings, lightweight reranking, aggressive caching, and small/latency-tiered models with schema-validated outputs.

Edge replicas for hot indexes; sharding for scale.

ANN search under 50–100ms; small reranker or scoring heuristics.

Latency-aware k selection; avoid over-fetch; cache top hits.

Grounded prompts with citations; schema validation (JSON).

KV cache reuse; response streaming; edge inference where possible.

Choose multimodal embedding models; build hybrid indexes with filters.
