H3
An AI video and image generation tool that supports AI-driven creation and editing of images and videos. It provides features such as Camera Control for creative direction and is targeted at AI content creators.
Core Facts
Prompt Studio can generate structured MiniMax H3 video scripts.
With the accelerator enabled, MiniMax H3 takes approximately 2 minutes to generate 1 second of video, approximately 14 minutes for a 480P ten-second video, and approximately 20–30 minutes for a 768P ten-second video.
H3 supports multiple video generation modes including text-to-video, image-to-video, and 3×3 grid video generation.
Timeline (last 90 days)
The H3 model has spatial errors and gacha-style quality degradation problems, requiring segmented gacha and segment-by-segment correction to ensure final quality.
H3 provides operations such as kRing (finding all cells within k rings around a given cell) and polyfill (filling an arbitrary polygon with hexagons).
Each hexagonal cell in H3 has 6 neighboring cells, and the neighborhood relationship is more uniform than rectangular latitude-longitude queries.
VITRide implements an H3-style spatial index in pure Dart, with an optional map grid overlay visualization.
H3 was open-sourced by Uber in 2018 and provides 16 resolution levels from 0 to 15, with the coarsest level having a cell area of about 4.25 million square kilometers and the finest level about 0.9 square meters.
H3 is a hierarchical hexagonal geospatial indexing system open-sourced by Uber that divides the Earth's surface into a hexagonal grid, where each cell has a unique index and multiple resolution levels are supported.
ReachNT's batch scheduling is implemented based on Uber's H3 hexagonal grid, dividing the Northern Territory into a hexagonal grid, with communities falling into adjacent cells grouped into shared weekly trips; across five random synthetic years, shared trips save 67 to 76 dollars per repair, against a baseline of about 821 dollars per repair.
Among T0-tier models, Seedance 2.5 has the highest visual quality, with H3, the Gemini series, and other leading models following closely behind.
Cloud platform credit conversion pricing: Seedance 2.5 averages approximately 2 yuan per second, Seedance 2.0 approximately 1 yuan, and H3 and the Gemini series approximately 0.6 to 0.8 yuan.
In the 2026 AI video generation model leaderboard, closed-source models overall still slightly lead open-source ones, while H3 from MiniMax stands out as the top model in the open-source space.

50%UnverifiedThe author cited a long single-take video of SeeDance 2.5 as a reference and expressed belief that the same could be achieved with H3.
50%UnverifiedThe refinement solution improved degradation control, but contrast still worsens over time and dissolve artifacts still appear in the background, meaning the problem has not been fully resolved.
