After deploying RAG across 12 enterprise clients, I can confidently say it still outperforms fine-tuning for most production use cases.
Here's what we found:
1. RAG gives you updateability — refresh knowledge without retraining
2. Fine-tuning wins on style/tone but loses on factual accuracy
3. Hybrid approaches (RAG + lightweight fine-tune) are the sweet spot
4. Cost difference is 10-50x in favo...

Controversial: The 'bigger is better' era of foundation models is ending.
Our latest research shows that smaller, specialized models (7-13B parameters) consistently outperform 70B+ generalists on domain-specific tasks when properly fine-tuned.
The future isn't one mega-model. It's an ecosystem of specialized experts.
A practical guide to model monitoring in production:
1. Track output distribution shifts (not just accuracy)
2. Monitor latency at p50, p95, and p99
3. Set up automatic fallbacks to simpler models
4. Log all inputs/outputs (with PII handling)
5. Create canary deployments for model updates
Most teams skip monitoring until something breaks. Don't be most teams.
