FreeModel supports OpenAI Chat Completions, OpenAI Responses, Anthropic Messages, and Gemini native generateContent for the live GPT text routes.
No Claude model ID is in the current live catalog. Claude Code can connect through the Anthropic Messages-compatible protocol, but the selected model is a FreeModel GPT route.
Both video-ds-2.0 and video-ds-2.0-fast accept 5, 10, or 15 seconds. Prices are 1,1, 2, and $3. Output is 720p.
No. familySlug is an internal Portal value. Public video requests use model, prompt, and the selected model’s media, duration, and framing fields.
Choose 1280x720 or 1920x1080 for 16:9 output. Choose 720x1280 or 1080x1920 for 9:16 output. Gemini Omni does not support square output. T2V, I2V, and R2V generate a fixed 10-second result. Extend derives its duration from video_url, so do not send seconds for that model.
I2V requires one or two source images. R2V requires one to five reference images. Each image is limited to 5 MiB. Extend requires one source video in the singular video_url field and accepts up to five optional image references. T2V does not accept image or video inputs.
Model IDs without -4k produce 1080p. veo3-1-lite-4k, veo3-1-fast-4k, and veo3-1-quality-4k produce 4K. All Veo routes are fixed at 8 seconds.
Lite, Fast, and Quality routes accept zero to two public image URLs. veo3-1-fast-ref requires one to three.
