new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

video-gen/models

5 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

video-gen models and quality-to-model mapping

The --model auto setting (default) maps the --quality parameter to a specific tier: --quality low maps to veo3.1-fast with 8s duration and 720p/1080p/4k resolution for cheap/fast filler; --quality medium (default) maps to sora-2 with 4/8/12/16/20s durations and 720p resolution for most stings with flexible length; --quality high maps to sora-2-pro with 4/8/12/16/20s durations and 720p/1024p/1080p resolution for hero intros and splash videos. The --model parameter can force a specific model using 'sora', 'sorapro', 'veo3-fast', 'veo3-quality', or 'veo3-lite'. Duration is snapped to the nearest value supported by the chosen model—for example, sora-2 has no 5s option, so a request for 5 seconds becomes 4.

video-gen supported durations per model

Duration support varies by model: sora-2 supports 4/8/12/16/20 seconds (no 5s option); veo3.1 supports 8 seconds only. When a duration is requested, it is automatically snapped to the nearest supported value for the chosen model. For example, a request for 5 seconds on sora-2 becomes 4 seconds. If a slightly longer duration is needed, use --duration 8 to avoid snapping down.

Duration constraints by video model

sora-2 and sora-2-pro support durations of 4, 8, 12, 16, and 20 seconds. veo3.1 supports only 8-second duration.

Resolution constraints by video model

sora-2 supports 720p only. sora-2-pro supports 720p, 1024p, or 1080p. veo3.1 (all variants: fast, quality, lite) support 720p, 1080p, or 4k.

Video model identifiers and capabilities

Video models and their specs: sora-2 (alias: sora/sora2) supports 4/8/12/16/20 seconds at 720p only; sora-2-pro (alias: sorapro/sora2pro) supports 4/8/12/16/20 seconds at 720p/1024p/1080p; veo3.1-fast (alias: veo3-fast) supports 8 seconds at 720p/1080p/4k; veo3.1-quality (alias: veo3/veo3-quality) supports 8 seconds at 720p/1080p/4k; veo3.1-lite (alias: veo3-lite) supports 8 seconds at 720p/1080p/4k. Sora and VEO have -official variants used when provider=official.
