CortexLab V6
Intelligence is a pipeline you can inspect.
Cortex V6 is not presented as a mysterious local LLM. It is an owned intelligence core built from routing retrieval graph reasoning calibration memory planning evaluation and human review. Each subsystem has a specific job and failure boundary.

Ten-stage intelligence core
Every stage has a reason to exist.
Retrieve
BM25 and TF-IDF lexical evidence plus a local dense semantic hash encoder
Connect
knowledge graph expansion brings prerequisites contrasts and related concepts into candidate retrieval
Rerank
lexical semantic graph scope exact-match and priority signals are combined into a hybrid score
Calibrate
confidence uses evidence agreement source coverage and top-result margin instead of copying a raw similarity score
Plan
Cortex selects a visible response plan based on intent topic difficulty memory availability and confidence
Answer
grounded extractive/template response with numbered evidence references and response-policy selection
Evaluate
answer quality checks grounding citation coverage confidence and uncertainty handling
Remember
signed-in learners can store visible deletable technical goals preferences and weak-topic memories
Improve
feedback updates response-policy Q-values while reviewed human teaching updates factual knowledge separately
What V6 does not claim
Architecture before marketing.
Not a pretrained frontier LLM
The dense semantic encoder is locally implemented feature hashing. It is useful for semantic-ish retrieval but it is not equivalent to a pretrained embedding model.
Not hidden chain-of-thought
Cortex exposes a compact response plan and evidence checks rather than claiming to reveal private internal reasoning.
Not automatic truth
Graph edges and human corrections influence retrieval only after scoring and review. Confidence is a calibration signal not a guarantee.
