About
LTX-2.3-IC-LoRA-Colorizer Model description Still a work in progress. Use with LTX-2.3 IC workflows to add color to black and white footage. It is not perfect by any means but for the best results I recommend to: - Use the IC-LoRA workflow from Lightricks and bypass the controlnet part (I can provide a workflow if wanted) - Prompt for what colors you want things to be - Use a colorized inference frame for better color control - Overlay the final result over your input using a "color" blend mode to preserve the fine details of the original footage. - Generate color maps at half your target resolution for speed.

Using it via the API
Once AxForge deploys ltx-2-3-ic-lora-colorizer for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (ltx-2-3-ic-lora-colorizer below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"ltx-2-3-ic-lora-colorizer","prompt":"a drone shot over a forest"}'
