Problem: RAG Embedding Dimension Mismatch after Model Update An event‑driven pipeline streams records into a PostgreSQL table that stores vector embeddings generated by a Retrieval‑Augmented Generation (RAG) model. After upgrading the model, inserts and similarity queries start failing with errors such as: ERROR: column “embedding” is of type vector(1536) but expression is of type vector(768) … Read more

Problem – Text‑Image Modality Mismatch after GPU Passthrough When running a multimodal model (e.g., llava‑1.5‑7b) inside a Docker container that uses the NVIDIA Container Toolkit, the generated responses contain text that is unrelated to the supplied image. The model appears to process the textual prompt correctly but ignores the visual content, resulting in incoherent or … Read more
