Ovis is an open-source Multimodal Large Language Model (MLLM) architecture that structurally aligns visual and textual embeddings, with releases like Ovis2.5 featuring native-resolution vision (NaViT) and an optional reflective 'thinking mode'. It ships model weights (2B-34B, quantized variants) and Python code for inference and fine-tuning on Hugging Face Transformers.

Use cases

• run a vision-language model for image question answering
• extract and understand charts, tables, and documents with OCR
• analyze videos and multi-image inputs with an MLLM
• deploy a small multimodal LLM on resource-constrained hardware
• fine-tune an open-source MLLM for custom multimodal tasks
• add visual grounding and image reasoning to an application

When to choose

• you need an open-source MLLM with strong chart/document/OCR performance at small scale
• you want native-resolution image understanding without lossy tiling
• you need an optional deep-reasoning 'thinking mode' trading latency for accuracy
• you want Apache-2.0 licensed weights with quantized variants

When to avoid

• you only need text-only LLM inference
• you need a fully managed multimodal API rather than self-hosting models
• you lack GPU resources for even the 2B model
• you need audio or speech multimodality, which Ovis does not cover
