by Jorge Ramírez Espejo JRamirez-UAB/Swift-1.5-Qwen3.8-27B-EXL3-3.85bpw-24GB

Swift-1.5-Qwen3.8-27B-EXL3-3.85bpw-24GB is an open-weight model for image and text to text from Jorge Ramírez Espejo, released under other. It has 7.9B parameters and a 262,144-token context. At 16-bit it needs about 19.1 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index. It draws 312 downloads a month.
