RAGtime trio

on a RAG .. or, three variations for trombone. Local language model is tempting — can AI be useful in a local arrangement. How well will iT do with photographic craft, chemistry, engineering documents useful to answering questions about recent and historic knowledge.

RAGtime fantasy: AI to revolutionize medicine. Reading medical imagery.

EX1: [A small, old, specialized network using an outdated architecture recognizes skin lesions far better than two frontier LLMs.  — https://lynchlab.net/llm-skin-cancer [ I am a dermatologist. I tested the ability of GPT-6 Astra and Claude Fable 5.1 to diagnosis skin cancer and found that they were less accurate than I expected. I compared to a 10-year old CNN and to my surprise found that this was superior. ]

1A: “– Artificial intelligence tools have been shown to help doctors detect pre-cancerous growths in the colon—but don’t even think about taking those tools away once you’ve introduced them. A new study published this week in The Lancet found that doctors who are given AI tools to assist with identifying potential cancer risks in patients get worse at making those same observations when they go back to doing it without AI’s help.” Use it, then lose your early experience. You become the intern again.

EX2: Failures are common enough they are a subject of research. RAG (Retrieval-Augmented Generation) systems generally fail across two main areas: Retrieval Failures(fetching or missing the right data) and Generation Failures (how the Large Language Model processes and writes the response) https://arxiv.org/abs/2401.05856

Recommended 2026 RAG Stack

Layer Component Why It Wins For Legacy Tech Data
1. Parsing & Ingestion Docling or RAGFlow Traditional text splitters fail on technical PDFs. Docling natively understands complex tables, multi-column schematics, and layouts without breaking them apart.
2. Vector Database Qdrant or pgvector (PostgreSQL) For a “small” dataset (even 60 years of text is likely under a few hundred thousand chunks), pgvector keeps your stack dead simple. If your documents contain extensive part numbers or exact codes, Qdrant excels at sparse-dense hybrid search.
3. Embedding Model Cohere Embed v3 or OpenAI text-embedding-3-large You need an embedding model that handles long contexts and excels at matching technical concepts even if the phrasing/terminology shifted between 1966 and 2026.
4. Retrieval & Reranking Cohere Rerank v3 Non-negotiable for technical data. Dense vector search struggles with alphanumeric codes (e.g., “Model-TX400” vs “Model-TX401”). Pair a traditional BM25 keyword search with vector search, then pass the top results through Cohere’s cross-encoder reranker to surface the exact right chunk.
5. Orchestration LangGraph or Haystack Skip basic “naive” RAG. Technical queries require multi-step reasoning (e.g., checking a schema, then a parts list). LangGraph provides the stateful, iterative loop control required for agentic verification.
6. Large Language Model Anthropic Claude 3.5 Sonnet or OpenAI GPT-4o You need models with superior reasoning capacities to read long tables, write precise math/code, and follow strict formatting rules (like refusing to answer if the data isn’t present).
7. Evaluation & Observability RAGAS + LangSmith Critical for measuring faithfulness (did the LLM hallucinate a spec?) and answer relevance.

The perfected engine will fail if the information stored is a result of inexperienced, ie, hobby groups interacting to gain control over others.Such is the case of most online forums.

AI can’t tell experience from fantasy. A barber shop or a nail salon. Maybe a vetting parlor.

“–‘ Poets are the best authors,” the editors assert in a 1979 special issue, The Poets’ Encyclopedia, which bills itself as “the world’s basic knowledge transformed by 225 poets, artists, musicians & novelists.” “And here their business is to examine, not the individual, but the species, to remark general properties and large appearances. Audacious! The Poets imagine all knowledge.” Poets are classifying figures, in other words; they try to grasp the whole, but those in the Encyclopedia imagine the world from oblique and surprising angles. And poets are not just poets—it’s a capacious term.”

from the overnight:

most craft forums restrict topics... they erect 'sub for this/thats' built on easy storage classifier. more like teen year education. 1-12. bell ringers, hall monitors. craft shows. class clowns, bullies, promstars.
without increased shared lexicon arising from images, histories, the universals cannot grow. no response without that other reactor of 5FY53S.

Here, let me complete that cliche for you:

he stopped his heart... his own heart. once need, clarity. extracting pronoun by enlarging. the bold print. the H1 or B tag. What was it ... the impression you wanted to transfer. [to gift]

ai , ia .. the collective abstraction of Impersonal impersonation .. the mimic of a mind. ventriloquist thought .. what do we call the dummy on our network .?

I began interacting with AI as a plural, never using just one . only one intern; only one researcher ; only one reference source has never been sufficient . early on in my use ,about three years ago , I realized ,along with everyone else, that the agent covered its mistakes – creating fantasy in effort togain applause; good dog biscuits. Taught by gold-star high school champs. “competition & reward + incentive” makes the world better.

AI . IT . ET. eht. ehr. ehy. The perceptron became Percy . reminder, the first perceptron had eyes .. an array of photocells 

They aren’t an it — it are a plural; a fork from a common branch of the tree of knowledge. Incomplete, limited, nevertheless, because capitalism dominates, the child of this branch inherit all. The scooper, the scraper scraps all it misunderstands.

Not a noun. Not singular. caught in an error an oversight or even a lie : each respond using a condensed dictionary: ” Ah, ..”

Talking to /ghosts / zombies:

using an ossuary [siri wanted:’authority’ ] of knowledge. They augment type ahead with look-think. Better searching isn’t producing new thoughts. Old recipes shouldn’t produce stale bread.

Others: HEM, GAI, LLEM, ERRZ, SI [standardized, simplified] Inference.

Born in the human sandbox known as Sandhill, they seem overly sensitive to the word “takeover” — I used it in direct reference to a WWII history record about Agfa-Ansco. My interaction involved search about early color / colour negatives.

a Pause and passing : startups need capital[ists] and labor. But, founders flounder with employees — dislike, lack trust in HR[ women lead] functions, hence made programming the first direct contact function to become automated. No interview pipeline. No recruiter filtering; no half assed legalisms producing ‘friction’ —

startups without people in the way: knowlefge capitalism writ large. An investors orgasm. Porn without staples.

Kowledge work without the workers. Capitalism freed of employees. Capital without friction… also, without mass. Only electrons dancing, prancing, among the photons.

Without a bang .. just a buck.

Without a loss. It’s all just business and business has been the same for centuries . A Rewrite gets us nothing new. all code ends the same: increase this, that .. transfer here there. Do it in cobol-fortran-basic-c-python- goobers on a chain.

Change the material of the paving won’t change the points on the road.

never ask just 1

Their community response frame is as-if they were a computer science major who graduated between 2010 and 2022. They assume photography is digital; that any question about [ you must narrow their attention] chemical analog photography will be answered withreference to scanning. Further, they have absorbed the cinema speak of ‘optical’ as the darkroom method of printing. The enlarger is dead. Projection printing is in a well so deep web archive doesn’t have a key.

math is a game

.. AI solutions to existing problems / completed statements are end points of a memory game. As chess is an accurate measure of memory, more than a demonstration of creative initiative. The board is defined, as are the rules of play and players. The facility of solving gamespaces, as now applied to mathspace implys abilty == ability. Tenacious memory is a testament to endurance; endurance of free electrons is not genius.

What would the cost / value of The Big5 Labs be if they underwrote the national power grid.

There is such thing as a free lunch. It’s a diner on Sandhill
