LTX 2.3 Knowledge — stored in ai_brain_kb
This skill no longer owns a separate collection. LTX 2.3 knowledge lives in the one brain,
ai_brain_kb, taggedltx23. The formerltx23_kbcollection was never created in Qdrant (verified 2026-08-09:GET /collections/ltx23_kb→Collection 'ltx23_kb' doesn't exist!), so there is nothing to migrate and no historical content is lost by this change.
mcp__better_qdrant__add_documentsis FORBIDDEN againstai_brain_kb— it does a bare-vector upsert with nobm25sparse slot and no payload (doc_type/title/tags/trust/host), so the point is invisible to typed and keyword search. Every write goes throughpython3 /home/n8n/bin/ai_brain_kb.py add ...and nothing else. Reads againstai_brain_kbare unrestricted.
Storage Location

What Goes Here
Everything LTX 2.3 related that should be searchable across sessions:
- Known issues — bugs, artifacts, model limitations, workarounds (
--type issue) - Resolutions / fixes — patches, config changes that solved problems (
--type finding) - Prompt suggestions — effective prompt patterns, structures, word limits (
--type prompt) - New modules — community modules, extensions, LoRAs, pipelines (
--type model/--type tool) - Official source tracking — Lightricks GitHub releases, changelogs, docs (
--type research) - Community findings — HuggingFace discussions, Reddit, Discord insights (
--type finding) - Render settings — proven configs (steps, guidance, resolution, CFG) (
--type setting) - Pipeline decisions — architecture choices, model chain wiring (
--type decision)

Search
# hybrid (dense + BM25) — the default, best for natural-language questions
python3 /home/n8n/bin/ai_brain_kb.py search --query "LTX 2.3 temporal consistency fix" --limit 10
# scope to LTX content
python3 /home/n8n/bin/ai_brain_kb.py search --query "prompt ceiling" --tag ltx23
# pure keyword / exact-string (filenames, error strings, model names) — no embedding call
python3 /home/n8n/bin/ai_brain_kb.py search --query "ltxv-097-dev-fp8.safetensors" --mode bm25
# by type
python3 /home/n8n/bin/ai_brain_kb.py search --query "artifacts" --type issue --tag ltx23
list, facet, recent and --mode bm25 do not call the embedder — prefer them
when you only need to enumerate or keyword-match (mini CARE rule).
Delete
python3 /home/n8n/bin/ai_brain_kb.py delete --doc-id <doc_id> --yes
Workflow: Save Research Findings
After researching LTX 2.3 (new release, bug fix, community finding):
- Dedup first —
search --query "<topic>" --tag ltx23. ≥0.85 skip · 0.70–0.84 add only if meaningfully new · <0.70 always add. - Write findings to a markdown file in
~/workspace/general/or a dedicated LTX workspace. - Add via the helper —
ai_brain_kb.py add --type <t> --tool ltx --tags "ltx23,..." --file <path>. - Confirm — the helper prints the
doc_idand chunk count; report both. - Verify — re-find it with
search --mode bm25 --query "<distinctive phrase>". A hit only on hybrid and not on bm25 is the bare-upsert signature and means the write was wrong.
Workflow: Research an LTX Issue
- Search the brain first —
search --query "<issue>" --tag ltx23, then without the tag for broader AI-video context. - If gaps found — dispatch web search for official sources (Lightricks GitHub, HuggingFace).
- Save results — add the research output with the helper, tagged
ltx23. - Proceed — now you have full context.
Official Sources
Primary sources to monitor (for cron-based updates):
- GitHub: https://github.com/Lightricks/LTX-Video — official repo, releases, issues
- HuggingFace: https://huggingface.co/Lightricks/LTX-Video — model weights, model cards
- HuggingFace Community: https://huggingface.co/Lightricks — organization page
Pitfalls
- Never
mcp__better_qdrant__add_documents— bare-vector upsert; the point becomes invisible to typed and keyword search. The helper is the only correct write interface. - Per-document delete EXISTS —
ai_brain_kb.py delete --doc-id <id> --yes. Nevermcp__better_qdrant__delete_collection(collection="ai_brain_kb")— that destroys the entire brain, not one document. - File paths must be absolute.
- Large files chunk automatically — the helper handles chunking; no need to pre-split.
- Embedding model must be running — Ollama with
snowflake-arctic-embed2on mini (10.0.0.30), the fleet's only embedder. Keep writes batched. - Scope with tags, not collections —
ltx23tag +--tool ltx. Do not create a new collection for a topic; the brain is one collection. - Search is hybrid — dense + BM25. Use
--mode bm25for exact strings, natural language for concepts. - Prompt ceiling — LTX 2.3 official limit is 200 words (Lightricks GitHub README). Community extends to 150-300 words for 10s clips. One main action per 2-3 seconds of video.
