AI Strategy

Build vs buy for enterprise AI platforms: how to decide

Buy the shared AI platform layer (data access, model gateway, permissions, audit, tracing) and build the workflows, prompts and tests that set you apart.

LLM Operations

Small vs large language models: choosing the right size

Use a small language model for narrow, repetitive tasks you can test, and a large one for open-ended reasoning and broad knowledge. Decide on your own data.

AI Governance

Role-based access control for AI assistants and agents

An AI agent should act with the permissions of the person it serves, capped by its own role, and every check belongs in retrieval and tools, not in the prompt.

RAG & Retrieval

Vector databases explained: what they do and when you need one

A vector database stores embeddings and finds the nearest ones fast with an approximate index. Below a few million vectors, your current database may be enough.

Edge vs cloud video analytics: latency, bandwidth and cost

Run video AI at the edge when uplink or response time is tight, in the cloud when you need heavy models and search, and in most sites, split between the two.

Data for AI

Data quality checks every AI project needs before launch

Before an AI launch, run automated checks for schema, nulls, duplicates, freshness, leakage, label errors and training-serving skew, and block on the worst.

AI Agents

Agent observability: what to trace in every AI agent run

Trace each AI agent run as one tree of spans: every model call, tool call and approval wait, with inputs, results, errors, tokens, cost and who it acted for.

AI Strategy

AI ROI: how to measure whether an AI project paid back

Measure AI ROI against a baseline taken before launch and a comparison group, count every cost, and value freed hours only where the time is actually reused.

LLM Operations

How to evaluate LLM applications: test sets, judges, regressions

Evaluate an LLM app with a test set built from real cases, cheap code checks first, an LLM judge you have checked against people, and a rerun on every change.

AI Governance

Prompt injection: what it is and how to defend AI agents

Prompt injection is text that hijacks an AI model's instructions. Agents can't be made immune, so limit what a fooled agent can reach and approve risky actions.

Data for AI

Data lineage explained: tracing an AI answer back to its source

Data lineage records where data came from and how it changed. For AI, join it to each run's record of documents, queries and dataset versions it used.

RAG & Retrieval

Chunking strategies for RAG: size, overlap and structure

Good RAG chunking splits documents on their own structure, keeps chunks a few hundred tokens with context, and tests size and overlap on real questions.

People counting with CCTV: how it works and how accurate it is

CCTV people counting detects people in each frame, tracks them, and counts line or zone crossings; accuracy depends on angle, crowding and light, so test it.

AI Agents

AI agents in production: what breaks and how to fix it

AI agents break in production through failing tools, loops, runaway cost and loose permissions. Limits, traces, approvals and evals keep them safe.

AI Strategy

AI for mid-sized companies: where to start and what pays back

Mid-sized firms get AI payback by picking one frequent, measurable task with accessible data, buying the platform, owning the process and judging it at 90 days.

AI Governance

AI governance in India: DPDP Act, audit trails, access control

Indian companies using AI on personal data must meet DPDP Act duties on consent, security, logs and breach notice, with most DPDP Rules in force from May 2027.

LLM Operations

Controlling LLM costs: gateways, budgets, caching and routing

Control LLM costs by routing all calls through one gateway, caching repeated prompts, sending routine work to small models and tracking cost per task.

AI Agents

Human-in-the-loop AI: when an agent should ask before it acts

An AI agent should ask a person before any action that is hard to undo, moves money, contacts outsiders or goes beyond its usual scope, and run the rest itself.

Is your data ready for AI? A practical readiness checklist

Data is ready for AI when it is findable, accurate, fresh, traceable and access-controlled for a specific use case. Score yours with this 10-point checklist.

MCP explained: how Model Context Protocol connects AI to systems

MCP is an open standard that lets AI apps call tools and read data from your systems through one protocol, so long as you control permissions and inputs.

RAG explained: why AI answers go wrong and how retrieval fixes it

RAG makes AI answer from your own documents by retrieving relevant passages first; most failures come from poor chunking, search, freshness or access rules.

Video analytics accuracy: why AI counts fail and how to prove it

AI video counts go wrong through compression, occlusion, ID switches and line jitter; prove accuracy by matching each counted crossing to a human ground truth.
