kanana-1.5-v-3b-instruct

The Unified Foundation Model (UFO) task force of Kanana at Kakao developed and released the Kanana-V family of multimodal large language models (MLLMs), a collection of pretrained text/image-to-text (TI2T) models.

Intended Use

kanana-1.5-v-3b-instruct is intended for research and application development in multimodal understanding and text generation tasks. Typical use cases include image captioning, document understanding, OCR-based reasoning, and multimodal instruction following in both English and Korean. The model is optimized for both general-purpose and Korea-specific benchmarks, making it suitable for bilingual environments.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys kanana-1-5-v for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (kanana-1-5-v below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/chat/completions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"kanana-1-5-v","messages":[{"role":"user","content":"Hello"}]}'
