microsoft/DialoGPT-medium	Dialogue Generation	500	28.79s	-	8.13s	❌ Conversion Failed

Success Criteria Validation¶

✅ Infrastructure Working: Core pull, convert, inspect, and cache functionality operational ✅ Pull Success Rate: 100% - All models successfully downloaded from Hugging Face ✅ Performance: Average time 20.24s < 30s target ✅ Model Support: At least one model type (text classification) fully supported

Phase 1 Assessment¶

Status: ✅ PHASE 1 VALIDATION PASSED

The Phase 1 validation successfully demonstrates:

Core Infrastructure: Pull, convert, inspect, and cache systems working correctly
Registry Integration: Hugging Face Hub integration functional
Model Support: Text classification models (DistilBERT) fully supported
Performance: Sub-30 second pull + convert + inspect times
Caching: Models properly cached and retrievable

Expected Limitations: Not all model types are supported yet (embeddings, generation, dialogue) - this is expected for Phase 1 and will be addressed in subsequent phases.

Methodology¶

Models: BERT-base, ResNet-50, GPT-2, Hugging Face models
Metric: Throughput (FPS - inferences per second)
Measurement: 1000 runs, 100 warmup iterations
Batch Size: Optimized per platform
Date: October 2024 (Updated October 2025)

Optimization Tips¶

For Maximum Throughput¶

Use TensorRT on NVIDIA (2-4x faster than CUDA)
Enable FP16 on RTX GPUs (2x speedup)
Optimize batch size (test 8, 16, 32)
Use quantization (INT8 for 2-4x speedup)

For Minimum Latency¶

Use batch size = 1
Enable GPU (10-50x faster than CPU)
Use smaller models (distilled versions)
Optimize preprocessing

For Best Efficiency¶

Apple Silicon for power efficiency
INT8 quantization for performance/accuracy balance
Right-size GPU (don't over-provision)
