How to Use Grok Imagine 1.5 Lite Image-to-Video API
grok-imagine-1.5-lite/image-to-video animates one uploaded image (image_url is a string, not an array) with sound built in. Price = per-second × seconds + $0.015 per image: $0.273 for 720P 6 s, $0.189 at 480P, $1.215 at 1080P. The aspect follows the image: 16:9 gives 1264×720, square gives 960×960 — rounded pixels, same ratio.
How to Use Grok Imagine 1.5 Lite Text-to-Video API: Sound Included
grok-imagine-1.5-lite/text-to-video turns one prompt into a 1–15 second video with sound built in (no off switch, no surcharge). Three per-second tiers: 480P $0.029, 720P default $0.043, 1080P $0.20 (~4.65× 720P). Seven aspects generated natively (16:9 through 1:1) — vertical and square aren't crops.
LTX Image-to-Video vs Wan 2.6 Flash: Which Should You Use?
Silent 720p: Wan 2.6 at $0.029/s beats LTX's $0.043 by 33%; silent 1080P is half ($0.043 vs $0.086). Two same-input, same-prompt pairs: the fox (LTX 1080P audio vs Wan 720p audio) and the convertible (both silent 1080P). First+last frames and 12 durations are LTX-only; Wan offers 5/10/15 with aspect-follows-image.
Grok Imagine 1.5 Lite API Pricing: $0.043/s at 720P
grok-imagine-1.5-lite bills the same per second on both endpoints: 480P $0.029, 720P $0.043, 1080P $0.2; i2v adds $0.015 per input image. One balloon prompt across three tiers (all 6 s, 16:9): 480P $0.174, 720P $0.258, 1080P $1.20. Sound always ships; durations run any integer 1–15; budget 1080P separately.
