// about
I'm Pras Vakati. I run vakati-tech.ai as a hands-on lab for agentic AI, RAG, semantic search, and commerce architecture — turning AI ideas into reference architectures, working demos, and guardrails your team can actually ship.
Picking the right model is part of shipping, so the site also tracks every major LLM live — price, context, benchmark scores and what each point of capability really costs — alongside guides on RAG, agent evaluation, MCP and healthcare drug commerce.
Not ready to talk? Get the lab notes — a short note when something meaningful ships — or follow new model releases.

AI systems shipped
30+
RAG, semantic search, copilots, and agentic workflows moving from prototype to production.
Commerce platform scale
$60B+
Architected and led delivery on a headless SAP Commerce platform powering $60B+ in annual healthcare e-commerce revenue.
Hands-on years
20+
Architecture, engineering leadership, and delivery across healthcare, retail, and global commerce.
The focus is pragmatic: define the workflow, map the systems, design the guardrails, and build enough working software to prove value. Whether the problem is agentic checkout, pharmacy refill orchestration, semantic product discovery, or SAP Commerce modernization, the goal is the same: help teams ship something credible and maintainable.
Every engagement leaves artefacts your team can adopt and evolve — reference flows, codebases, evaluation harnesses and delivery plans — rather than a deck.
Live model data for the decision every AI project starts with: which model, at what cost.
Every model ranked on benchmark score, price and measured cost per point of capability.
OpenClaude Code, Codex, Cursor, Copilot and more — every plan, the models it includes, and how they score.
OpenDescribe a workload and see the monthly bill across every priced model, cache discounts included.
OpenThe new categories, the weighted Overall score, and which models rose and fell.
OpenPublished sources only
Prices, context and capabilities from OpenRouter; scores and measured spend from LiveBench; coding-tool plans from each vendor's pricing page.
Refreshed every 15 minutes
New models get a page the day they're callable, and price changes show up without a redeploy.
No invented numbers
No blended scores of our own and no guessed matches. A model without a published run shows blank — “not evaluated”, never “bad”.
Architecture diagrams, scenario playbooks, and working demos that connect AI capability to commerce and healthcare workflows.
Commerce and healthcare drug e-commerce scenarios with examples, guardrails, and operating models.
OpenArchitecture flow diagrams for shopping agents, pharmacy workflows, and multi-agent orchestration.
OpenSynthetic drug catalog semantic search with filters, ranking, and explainable product discovery.
OpenTwo decades of engineering rigour, product judgment and leadership — the mix needed to move AI from slides into systems.
