Traditional ML (gradient boosting, neural nets, classical statistics) dominates on structured data, classification at scale and low-latency inference, while LLMs excel on fuzzy reasoning over unstructured text. According to a 2024 Gartner report, 61% of successful AI deployments use traditional ML as the primary model with LLMs only as a specialized sub-component - not the other way around.
| Factor | Traditional ML | LLM-based approach |
|---|---|---|
| Input type | Structured features, numeric, categorical, time-series | Unstructured text, docs, conversations |
| Accuracy ceiling | Very high on narrow tasks with enough training data | Very high on fuzzy tasks with prompt engineering |
| Latency | Sub-millisecond to tens of milliseconds | 0.5-15 seconds typical |
| Cost per prediction | Near-zero marginal cost once trained | $0.001-$0.05 typical; adds up at scale |
| Determinism | Deterministic (same input → same output) | Non-deterministic; same input can yield different outputs |
| Training data | Requires thousands+ labeled examples | Works with zero-shot or few-shot examples |
| Explainability | High for tree-based (SHAP, feature importance); moderate for neural nets | Limited; requires additional techniques |
| Best fit | Fraud, recommendations, forecasting, classification at scale, computer vision | Document processing, conversation, content generation, fuzzy Q&A |

Three ML engagements across different problem classes with the feature engineering call that moved the metric.
Rules-based fraud detection caught 41% of fraud attempts. Each rule update required 2-3 weeks of engineering work. Fraud loss rate 0.8%.
Custom gradient-boosting model trained on transaction patterns. Caught 87% of fraud attempts with 0.4% false positive rate[4]. Continuous retraining monthly. Fraud loss rate dropped to 0.12%.
Features derived from velocity, graph relationships and device fingerprints; a LightGBM model serves predictions in sub-50ms at checkout. Hard rules still handle sanction lists and hard blocks; the ML tier handles grey-area scoring.
Case reviewer: Senior ML Engineer, 8+ years Gradient boosting and feature engineering for FinTech fraud, sub-50ms p99 serving and shadow-mode rollouts
Static popularity-based recommendations. CTR on product recommendations 1.8%. Cold-start problem for new users and new products.
Two-tower neural recommender with collaborative filtering + content-based features. CTR up to 7.2%[12]. Cold-start handled via content embeddings and contextual bandits. GMV from recommended products up 38%.
The two-tower architecture let us encode users and products into the same embedding space, so cold-start products get recommendations based on content similarity alone. The contextual bandit layer handles exploration on new products to build up interaction data.
Case reviewer: Staff ML Engineer, 10+ years Two-tower neural retrieval, contextual bandits for cold-start and feature store integration for marketplace ranking
Manual demand forecasting based on last-year sales + gut feel. Stockouts cost $2.1M per quarter. Overstock cost $900K in carrying costs.
Prophet + custom XGBoost hybrid with SKU-level seasonality and promotional calendar features. Stockout cost down 68%, overstock down 54%. Forecast accuracy (MAPE) improved from 34% to 11%[3].
We started with Prophet as a strong baseline for seasonality, then layered XGBoost on top to capture promotional lift, weather effects and macro trends. The hybrid outperformed either model alone by ~8 percentage points on held-out MAPE.

Our card-not-present fraud detection jumped from 41 percent to 87 percent true positive rate with false positives held at 0.4 percent. The LightGBM model clears checkout in 50 milliseconds at p99, which meant zero impact on conversion. Pharos shipped the full pipeline in 11 weeks and the drift monitoring caught a payment processor schema change before it hit revenue.
We had a two-tower recommender replacing a popularity fallback and the CTR moved from 1.8 percent to 7.2 percent over eight weeks of A/B. GMV is up 38 percent year on year and the team onboarded our feature store so retraining runs monthly without us babysitting it. The eval harness they left behind is still catching regressions six months later.

We decline roughly 30% of RFPs we receive. Forcing a bad fit costs both sides 3-6 months and damages outcomes. Here is how we think about scope:
ML makes sense when you have high-volume decisions, enough historical data to train on and a measurable business metric tied to accuracy. For low-volume or rule-based decisions, a heuristic or SQL query is cheaper and auditable. For natural language tasks with limited training data, LLM few-shot prompting is faster. We have closed engagements with "write the rules, we will come back when you have enough data for a model" as the deliverable.
Pharos ML portfolio
Ranges we consistently see across 30+ ML engagements.
12-28% primary-metric lift over documented baselines on first production model deploys; 2-8% additional lift on subsequent iteration rounds.
6-14 weeks from discovery to production deploy for mid-complexity models with data pipeline, training and serving infrastructure[5].
$3k-$18k per month for training and serving infrastructure on mid-market ML workloads; scales to $20k-$75k at high-throughput (10M+ daily predictions)[7].
Quarterly retraining on stable use-cases; weekly on fast-moving domains (fraud, recommendation) with automated trigger on drift breach.
60-85% of production features reused across 2+ models on teams with mature feature stores; significantly reduces time-to-second-model.
Three shifts are reshaping classical and deep learning delivery.
Gradient-boosted trees and well-tuned classical ML drive 60-75% of measurable enterprise ML value despite LLM hype. XGBoost and LightGBM remain first-choice for most structured-data problems[3].
Feature store adoption crosses from "advanced teams only" to standard infrastructure. Online and offline consistency, not just store-and-retrieve, becomes the differentiator[11].
Model cards, dataset provenance and bias eval artifacts enter procurement requirements. Teams without published evaluation evidence fail enterprise review[8].
Every ML system we ship runs against the same four-dimension readiness evaluation before handover.
Production post-mortem
A credit-scoring model deployed in June 2025 served predictions from a feature store with a 5-minute TTL. The batch training pipeline used 24-hour snapshots. A new feature column was added to both paths but the serving cache retained the old schema shape for 5 minutes after deploy. Predictions served during the window used stale feature vectors and caused measurable false approval rate increase before rollback.
Feature store deploys now require explicit cache-warm and version-bump; schema-mismatch rejects fail closed in serving not open. Training-serving parity check runs on every deploy. TTL-based caches versioned with schema hash.

Use traditional ML for classification at scale, fraud detection, recommendations, time-series forecasting and anywhere determinism and low latency matter more than reasoning ability. Use LLMs for fuzzy tasks over unstructured text, document extraction, conversation, content generation.
Most production AI systems combine both. The rule of thumb: if you have thousands of labeled examples and need sub-50ms latency, traditional ML wins.
Depends on the problem. Simple classification: 1,000-10,000 labeled examples.
Deep neural networks: tens of thousands to millions. Time-series forecasting: 2-3 seasonal cycles of history minimum. Computer vision: thousands of labeled images per class for custom models (pre-trained models work with fewer). We assess data sufficiency in discovery before committing to a model approach.
ML MVP 8-14 weeks: 2-4 weeks discovery + data exploration + baseline, 4-6 weeks model development and evaluation, 2-4 weeks production serving and MLOps setup. Production ML with full MLOps (model registry, feature store, drift detection, automated retraining) 4-9 months.
The biggest variable is data quality and availability - most ML projects underestimate data work.
MLOps is the infrastructure and discipline that makes ML systems reliable in production: model versioning, reproducible training pipelines, feature stores, monitoring for data drift and model drift, automated retraining, A/B testing and rollback procedures. Without MLOps, models silently degrade as the data changes and nobody notices until a customer complains. Every production ML engagement includes an MLOps baseline appropriate to the scale.
We instrument feature distributions and prediction distributions on every inference, compare week-over-week and month-over-month to a baseline and alert when KL divergence or prediction distribution shift exceeds a threshold. For supervised models where ground truth is delayed, we track prediction vs reality on the lag and trigger retraining when accuracy drops below the SLO.
Retraining runs on a monthly schedule by default, more frequent for fast-moving domains.
Yes. PyTorch + torchvision for custom models, Hugging Face Transformers for pre-trained vision-language models (CLIP, BLIP, LLaVA), Ultralytics YOLO for object detection, Segment Anything for segmentation.
Production computer vision typically uses a pre-trained backbone + a small custom head trained on client data. We have shipped fraud document verification, product recognition, defect detection and medical imaging (with appropriate compliance).
Yes. We integrate with existing feature stores (Feast, Tecton), MLOps platforms (Vertex, SageMaker, Databricks, MLflow), experiment tracking (Weights & Biases, Neptune) and serving infrastructure.
We avoid creating parallel ML infrastructure and prefer to add capabilities to your existing data plane. Codebase audits ($8K-$25K) review an existing ML system, document the architecture, flag risks and deliver a prioritized improvement roadmap.
We decline problems solvable by rules at 1/10 the cost, ML projects without enough labeled data, use cases where LLM few-shot would ship faster, real-time systems without a latency budget and "we want AI" projects with no measurable business metric. We start every ML engagement by asking "what happens if the model is wrong?" If the answer is "nothing specific", there is no business case for ML.
ML rewards teams that invest in data pipelines, evaluation rigor and deployment plumbing as much as in model selection[10]. Tabular-first discipline, feature store consistency and published evaluation evidence are the three areas that separate ML systems that ship value from ML experiments that stall.
