Custom Model Training

Your business. Your models.

Generic AI models don't understand your business. Labelf lets your domain experts — not data scientists — train models that learn your language, your categories, your edge cases.

Three modes

Start instantly. Improve continuously.

Begin with zero-shot classification — no examples needed. As you refine, the model gets sharper. No data science team required at any stage.

Training ModesChoose your starting point · upgrade anytime
Zero-shot
Instant. No examples.

Describe what you want to classify in plain language. The model starts working immediately based on your instructions alone.

Examples needed0
Typical accuracy~75%
Time to deployMinutes
Ideal for: Exploration, rapid prototyping, initial hypothesis testing
Prompt Tuning
Refine with instructions.

Write detailed instructions with edge cases, test against a validation set, and iterate on the prompt until it performs well.

Examples needed10–50
Typical accuracy~85%
Time to deployHours
Ideal for: Quick deployment, moderate complexity, testing edge cases
Fine-tuning
Production-grade accuracy.

Label examples with Active Learning assistance. The model trains on your data using LoRA/SetFit and deploys as a dedicated classifier.

Active Learning

Label smarter, not harder.

You don't randomly label examples. Labelf analyzes the model's weaknesses and recommends exactly which examples will improve it the most. Label 200 smart examples instead of 2,000 random ones.

It finds edge cases, flags your mistakes, balances classes, discovers rare patterns — so your model learns what matters, fast.

Active Learning
Check labelingThe model thinks you might have missed this one

You labeled this "Service cancellation" but the model is 94% sure it's "Product inquiry"

"What happens if I cancel my add-on? Do I lose the discount on my main plan?"

Training Advisor

The system tells you what to fix next.

Prioritized actions: which classes need more data, which confuse each other, which are star performers. With level progression so you always know how close you are to the next quality tier.

Training Advisor
Priority actions to improve your model
1
"Invoicing" is drowned outMEDIUM RISK

It has 52% less data than the average (72 vs 151). The model is biased towards larger classes.

Add about 4 examples to level the playing field.
Lvl 7
72 samples+26 to Lvl 8
2
"Cancellation" loses to "Service change"HIGH RISK

When the answer was "Cancellation", the model guessed "Service change" 14 times. The boundary between these classes is unclear.

Add examples that clearly distinguish intent to leave vs intent to modify.
Lvl 9
167 samples+31 to Lvl 10
3
"Network issues" — Star PerformerStar Performer

Reliable accuracy (100%). 294 samples at Level 13. No actions needed.

Lvl 13
294 samples+44 to Lvl 14
4
"Password reset" could reach Level 8LOW RISK

81 samples with 100% accuracy. Just 17 more examples would push it to the next confidence level.

Add 17 examples — use Active Learning recommendations.

The people who know the business train the models.

QA analysts, team leads, process developers — the people who actually understand your customers. They click buttons, not write code. Labelf handles the AI.

QA Analyst

Labels examples at 200-400/hr. Finds patterns in conversations. Validates model output.

Team Lead

Defines categories based on how the team actually works. Sets edge case rules. Reviews model accuracy.

Process Developer

Designs the classification hierarchy. Connects models to dashboards. Builds reporting workflows.

Labelf

Handles model architecture, training, deployment, scaling, and active learning. Zero infrastructure for you.

Team performance

Know who labels well — and who needs help.

See every labeler's volume, pace, agreement rate, corrections received, and accuracy trend over time.

From description to production in minutes.

Traditional ML projects take months. With Labelf, you describe what you want, the model starts working, and you refine it with your team until it's production-ready. The platform handles everything else.

  • Describe → Classify instantly Write what you're looking for in plain language. Zero-shot classification starts immediately.
  • Label → Refine with Active Learning The system recommends what to label next. 200 smart examples beat 2,000 random ones.
  • Deploy → Run on everything One click deploys the model. Every new interaction is classified automatically. Feeds dashboards, alerts, and playbooks.

Unlimited depth

Go as deep as you need.

Build unlimited hierarchies within a single dimension. Each level trains a dedicated model on just the subset that matters. The deeper you go, the more specific the intelligence gets.

Customer Interest 3 levels deep · trained from conversations
L1 Streaming 22% of customers
L2 Sports 14%
L3 Hockey 78% convert on TV Premium
L3 F1 65% convert
L3 Football 41% convert
Skiing · Tennis · ...
L2 Fantasy & Sci-fi 5%
Documentaries · Kids · ...
L1 Summer house 8%
Travel · Remote work · Gaming · ...
Full conversations or single utterances

"Was the customer retained?" needs the full conversation. "Is this a billing question?" needs one message. Choose per model. Include surrounding context when needed.

Contact Reason 3 levels deep · root cause drill-down
L1 Invoice $42K/mo
L2 Perceived wrong information $28K/mo
L3 Wrong price $12K/mo
L3 Wrong date $9K/mo
L3 Wrong services $5K/mo
Product mismatch · VAT · ...
L2 Missing invoice $8K/mo
Payment failed · Refund request · ...
L1 Service $31K/mo
Order · Cancellation · ...
Each level is its own model

Level 1 runs on all interactions. Level 2 trains only on "Invoice Issues" — a focused model that's better because it's specialized. Level 3 goes deeper still. Each model is simple. The hierarchy creates the depth.

Bucketeering

Cross everything against everything.

Every model you train creates a new dimension. Every dimension gets crossed against every KPI — CSAT, AHT, churn, sales, resolution, cost, transfer rate. Thousands of buckets. In those buckets, you find the patterns that no one could see before.

Dimensions × KPIs
2,000+ categories × 18 KPIs = 36,000+ data points

Every model adds a dimension

Train a new model and it instantly creates new cross-references with every existing KPI and dimension. The more models, the richer the picture.

Anomalies surface automatically

The system monitors all buckets continuously. When a combination spikes or trends, it flags it. You don't search for problems — they find you.

Filter, slice, drill down

Every dimension is a filter. Every KPI is a sort. Start broad, narrow down, find the specific bucket that costs you $18K/month. Then fix it.

Models are the engine. Everything else follows.

Every model you train powers the rest of the platform. AI Search helps you find the training examples. Model Evaluation shows you where it's right and wrong. And the models feed directly into Dashboards, Playbooks, and every solution.

Built for domain experts, not data scientists.

The people who know your business best should be the ones training your AI. Labelf makes that possible.
