Fine-tuning for Qwen 2.5 VL vision-language models, with up to 64K context
You can now fine-tune Vision-Language Models (VLMs) on Fireworks AI using the Qwen 2.5 VL model family. This extends our Supervised Fine-tuning V2 platform to support multimodal training with both images and text data.
Supported models:
- Qwen 2.5 VL 3B Instruct
- Qwen 2.5 VL 7B Instruct
- Qwen 2.5 VL 32B Instruct
- Qwen 2.5 VL 72B Instruct
Features:
- Fine-tune on datasets containing both images and text in JSONL format with base64-encoded images
- Support for up to 64K context length during training
- Built on the same Supervised Fine-tuning V2 infrastructure as text models
See the VLM fine-tuning documentation for setup instructions and dataset formatting requirements.
