Sustainable AI Architecture with OtaskuAI

A practical look at keeping AI experimentation lightweight: selecting infrastructure that matches the maturity of the problem, not the hype level of the week.

Type
Architecture & cost governance
Scope
Deployment tradeoffs + spend visibility
Outcome
Prefer minimal viable infra for exploration
Context

OtaskuAI is exploratory — which means the architecture should be, too. The case study evaluates how to run early-stage AI experiments without accidentally launching a disastrous monthly bill.

Key question

What is the minimum viable infrastructure that still supports meaningful AI experimentation?

Option A — Serverless inference
  • Near-zero idle cost
  • Cold starts acceptable for low-traffic exploration
  • Easy to iterate and roll back
Option B — Persistent endpoints
  • Always-on cost regardless of usage
  • Good for steady traffic / strict latency needs
  • Often premature early in a project
Decision and rationale

For exploration phases, serverless is favored: it supports fast iteration and keeps spending aligned to actual usage. Persistent endpoints can come later — when the problem and demand justify them.

  • Infrastructure maturity should follow problem maturity
  • Spend visibility prevents “silent budget creep”
  • Define infrastructure via IaC to keep changes intentional
