Prompt Injection Detection in Production: What to Alert On
Where injection detection sits in the serving path, which metric to tune (recall at a fixed false-positive rate), and how to shadow-test it.
-
LLMOps Tools on GitHub: The Open-Source Stack
A layer-by-layer map of the open-source LLMOps stack on GitHub, from serving and gateways to tracing, evaluation and guardrails, plus how to vet a repo.
-
Serverless vs Dedicated GPU for LLM Hosting
Serverless GPU containers scale to zero but pay for it in cold starts and lost batching. Here is the duty-cycle math that decides which one is cheaper.
-
vLLM vs TGI Serving Comparison: Throughput, Latency, and EOL Risk
A vLLM vs TGI serving comparison covering PagedAttention, continuous batching, and why TGI's maintenance-mode status now outweighs raw benchmark numbers.
-
LLM GPU Cost Optimization Techniques That Move the Needle
Four LLM GPU cost optimization techniques that pay off: quantization, KV cache management, continuous batching, and parallelism, and when each fits.
-
Self Hosting LLM vs API Cost: A TCO Breakdown for 2026
Self hosting LLM vs API cost, broken down: hardware, cloud GPU rental, engineering overhead, and the utilization trap that breaks most breakeven math.
-
Best LLM Serving Frameworks 2026: vLLM, SGLang, and TensorRT-LLM
How vLLM, SGLang, TensorRT-LLM, and Ray Serve stack up on throughput, TTFT, and operational complexity — and which one fits your workload in 2026.
-
Best Vector Database for RAG: A Practical Comparison (2026)
Pinecone, Weaviate, Qdrant, pgvector, Chroma and Milvus compared on the published recall@k, p99 latency, filtered-search and cost figures for each.
-
Semantic Caching for LLM Serving: Hit Rates and Failure Modes
Exact-match caching misses most LLM cache hits — paraphrases tank hit rate. Semantic caching, threshold tuning, and the production failure modes that bite.
-
LLM Eval Pipelines in CI/CD: Gates That Actually Catch Things
Running LLM evals in CI is easy to set up and easy to get wrong. How to build quality and red-team gates that block bad prompts before they ever ship.
-
Prompt Versioning and Deployment: The Operational Workflow
Versioning prompts is the easy part. The hard parts are decoupling prompt releases from code deploys and keeping staging and production labels honest.
-
RAG Observability: Monitoring the Retrieval Layer in Production
When a RAG system gives a bad answer, the retrieval layer is usually to blame — and your LLM monitoring can't see it.
-
Guardrails in the Serving Path: Defense in Depth for LLMs
Guardrails are not a single check you bolt on — they're layers in the request path, each catching what the others miss.
-
LLMOps Best Practices: From Prototype to Production
LLMOps best practices that separate fragile demos from reliable production systems: prompt versioning, observability, evaluation and cost control.
-
Model Registry Patterns That Actually Work
What the hype skips about model registries, what mature teams actually do, and how to avoid the metadata graveyard most registries become.
-
Token-Cost Observability: What You Measure vs What You Should
Most LLM apps track total spend and call it done. Per-feature cost, per-user attribution and anomaly bands all require deliberate instrumentation.
-
Training/Serving Skew: The Silent Killer
How training/serving skew happens, why it's so hard to see, and the specific places to look when your model works in eval and breaks in prod.
-
MLOps Tool Review: Arize vs Evidently
An honest comparison of two ML observability tools—where each fits, where each frustrates, and what neither one solves.
-
Concept Drift Detection in Production: Practical Thresholds
How to actually detect concept drift in live systems, what thresholds matter, and why your monitoring dashboard is probably lying to you.
