Adapter-native intelligence
Embedding Adapters On Your Data
Lethonium adds a lightweight layer on top of foundational embedding models, enabling classification, topic clustering, and domain-specific retrieval for RAG pipelines — without modifying the original checkpoint. Think of it as hot-swappable lenses for your vector space.

Why adapters
Focus on the final mile insights your analysts argue about.
Retraining an embedding model for every new classification question is slow and expensive.
We keep the trusted model, then train super-light adapters (<64M params) that zero in on the business label you care about.
Adapter-only fit
Freeze the base model and tune <10 min clip-on adapters.
Hybrid compute
Embeddings in the cloud, adapters on laptop, edge, or VPC.
Hot swap semantics
Swap stance, sentiment, urgency, or geo without reindexing.
Map business intent
Teach the adapter exactly which tone, stakeholder, or urgency levels matter so classification mirrors how your team reads.
Deploy anywhere
Adapters weigh <70 MB and run on CPU. Ship them to field teams, BI dashboards, or keep them in our managed infra.
Always measurable
Every adapter ships with a validation report, drift monitors, and a rest API so ops teams can sign off.

How it works
Adapter to your needs - lightweight tuning and inference
Align
Upload a CSV, connect a warehouse table, or synthetically generate datasets. We train an adapter based on your needs.
Adapt
Adapters train on top of the frozen base model. Expect convergence in ~1,000 steps with live validation curves.
Deploy
Stream embeddings through our OpenAI compatible embeddings API, or host the adapter yourself with our Python Package.
Where it lands
One base model, endless adapters.
Lethonium seamlessly integrates adapters into classification or RAG tasks across any domain—including monitoring, research, medical, legal, operations, and compliance.
Understand every opinion
Correlate editorial tone with impact. Rank supporter vs detractor coverage without manual review.
Stay ahead of shifts
Reduce time-to-flag by 70% by syncing a sentiment adapter to your alerting rules and CRM.
Retrieve on Your Domain
Use adapters based on your domain specific retrieval pipelines.
Swap focus on demand
Toggle between policy, risk, or supply-chain adapters when leadership wants a new lens on the same dataset.
Ready?
Ship adapters that speak your business language.
We run collaborative working sessions, ingest your labeled examples, and ship adapters you can hot swap across every embedding-powered workflow.
