# LTX Notes
|
|
|
|
## Current default assumptions
|
|
|
|
- Low-VRAM practicality matters more than graph sophistication.
|
|
- The first question is whether `LTX 2.3` is usable at all on Chris's `3070`.
|
|
|
|
## Strong current source workflows
|
|
|
|
- `models/ltx/ltx23-i2v-t2v-simple-single-pass/`
|
|
- `models/ltx/ltx23-t2v-simple-single-pass/`
|
|
- `models/ltx/ltx23-first-last-frame/`
|
|
- `models/ltx/ltx23-character-sheet-best-face-id/`
|
|
- `models/ltx/ltx25-multiple-subject-reference/`
|
|
|
|
## Strong current heuristics
|
|
|
|
- Start with simple single-pass before trying larger consistency graphs.
|
|
- Prefer split-model and extracted-model routes when the source pack says they are easier locally.
|
|
- Treat first-last-frame and character-sheet workflows as second-wave tests, not the baseline.
|
|
- Keep the `LTX-2.5` multi-subject reference pack as the best current donor for heavier consistency work, but do not let it displace the simpler `LTX 2.3` master until we have proof on the `3070`.
|
|
|
|
## Current weak areas
|
|
|
|
- No real proof yet for what is genuinely practical on Chris's box.
|
|
- Community packs bundle lots of helper nodes, which raises import fragility.
|
|
- The newer `LTX-2.5` reference pack looks promising, but it is not yet a clean default candidate.
|
|
|
|
## Best current optimization direction
|
|
|
|
- Keep `optimized/image-to-video/ltx23-3070-simple-master/` as the first `LTX` default.
|
|
- Only promote first-last-frame or character-sheet variants after the simple master proves viable.
|
|
- Use the `LTX-2.5` multi-subject reference workflow as a future donor for reference-heavy jobs, not as the baseline.
|
|
|
|
## What needs Monday proof
|
|
|
|
- whether the simple master loads and runs at all on the `3070`
|
|
- whether preview/decode or the core model path is the real bottleneck
|
|
- whether `LTX` has any realistic chance of displacing `MiniMax` for local use
