Feature clusters forming

! Layer 12: Degradation detected

The Problem

  • Foundation models fail in production
  • Hallucinations, bias, edge case failures
  • Traditional fix: retrain everything for $2M and 3 months
$2M+ cost
3+ months

The Old Way

  • Blind debugging: add more data, hope it helps
  • Full model retraining: expensive and slow
  • No insight into WHERE models break

"We spent 6 months adding data, only to find the issue was in layer 14."

The Spectral Labs Approach

Debug models with precision, not guesswork

Our three-step process gives you complete visibility into your model's internal representations.

Visualize

See inside your model layer-by-layer

NCut spectral clustering reveals semantic structure. Identify exactly where features degrade.

  • Layer-by-layer feature visualization
  • Semantic cluster identification
  • Real-time analysis pipeline

Debug

Track feature evolution across layers

Compare model architectures side-by-side. Batch analysis across edge cases.

  • Side-by-side architecture comparison
  • Edge case batch analysis
  • Automated degradation detection

Fix

Swap in high-performance feature spaces

No retraining required. Benchmark improvements instantly.

  • Feature space swapping
  • Zero retraining deployment
  • Instant benchmarking

Model Observability for Foundation Models

See exactly where your model's features degrade with layer-by-layer spectral analysis.

NCut Visualization — Layer 12

⚠️ Layer 12: Feature separation degrades here

Cluster entropy increased by 34% from Layer 11. Consider feature space replacement.

Included Features

  • Real-time spectral analysis
  • Layer-by-layer comparison
  • Batch debugging across edge cases
  • Export visualizations and reports

Quick Start

from spectral_labs import SpectralDebug

debug = SpectralDebug(api_key="your_key")
debug.connect_model(model="llava-1.5-7b")
result = debug.analyze(images=batch, layer=12)
result.visualize()

How It Works

Get started in three simple steps. No complex setup required.

Step 01

Connect

Install SDK and connect your model via API key

Works with PyTorch, HuggingFace, JAX

Step 02

Visualize

Run NCut analysis on your feature spaces

See layer-by-layer semantic structure

Step 03

Fix

Identify weak layers, swap in better features

Benchmark improvements, ship to production
