Engineering labs with an AI tutor, on NVIDIA NIM.

Three free, browser-based labs for the S5 Artificial Intelligence (PECST522) and S7 Compiler Lab (CSL411) courses. Every answer is checked by the lab itself; when a student is stuck, an AI tutor running on NVIDIA Nemotron via build.nvidia.com explains the next step. Start with a two-minute video, then pick a lab.

Labs with an NVIDIA AI tutor

Counted since 1 Sep 2026 from this server's own access logs and the labs' request ledger, refreshed daily (13 Oct 2026). Known bots and scripts are excluded. A whole classroom on the college Wi-Fi shares one IP address, so device counts undercount students. Raw figures: nvidia-labs-stats.json. Independent check: see Independent analytics below.

Independent analytics / Matomo

Measured by Matomo, the open-source analytics platform, self-hosted on this server. The dashboard is public and read-only: no login needed.

Open the live analytics dashboard ↗ Figures refreshed hourly from Matomo's public API.

Lab pages are those under /ai/ and /compiler-lab/. Visits before 13 Oct were imported from the server's access logs; since 13 Oct every lab page also reports live to Matomo (cookieless, IP-anonymised). Visits from a whole classroom on one college Wi-Fi IP can merge, so these figures undercount students.

Watch on YouTube ↗ · Get your free NVIDIA API key

  1. Open build.nvidia.com and sign in. It is free and needs no card.
  2. Open any model page, choose Get API Key, and copy the key that starts with nvapi-.
  3. Pick a lab below, open its AI tutor panel, paste the key and press Test.

Your key stays in your browser. Each tutor request is relayed once to NVIDIA's hosted endpoint and the key is never stored or logged on this server. No key? Every lab still works: the checkers, hints and visualisations run without it.

Labs with the NVIDIA AI tutor / 02

CSL411 · COMPILER LABNVIDIA NIM
LEX–YACC Lab
52 past university questions. Write a LEX/YACC program, run it on test inputs, and get an automatic verdict. The AI tutor explains a failing case, gives a graded “unstuck” hint, or answers a question about your code.

PECST522 · MODULE 3NVIDIA NIM
Logic Lab
Build propositional-logic derivations step by step: reasoning patterns, CNF, resolution, forward and backward chaining. Every line is checked instantly. The AI tutor explains a rule or writes study notes for the proof in front of you.

PECST522 · MODULE 3NVIDIA NIM
Wumpus Justify
Explore the Wumpus world and justify every move in your own words. A rule-checker grades the logic; the NVIDIA-hosted model judges whether the explanation is actually sound, the way an examiner would.

How it is built / 04

MODEL
NVIDIA Nemotron 3 Ultra
nvidia/nemotron-3-ultra-550b-a55b on the OpenAI-compatible endpoint integrate.api.nvidia.com/v1, with an automatic fallback model from the same NVIDIA catalog.
GROUNDING
The lab checks, the model explains
Correctness comes from deterministic checkers (a LEX/YACC runner, a logic verifier, a Wumpus rule engine). The model only sees the student's current step and the checker's verdict, so it explains rather than guesses.
PRIVACY
Bring-your-own key, never stored
Keys live in the student's browser. Student text is not logged. Usage counters are aggregate only: no names, no roll numbers.

Workshops & partnership / 05

Open the AI tutor to every learner.

Today each student must create their own NVIDIA key, which stops many first-time visitors and students from other colleges before they try a lab. We are looking for support from NVIDIA to:

  • offer a shared, rate-limited “try without a key” tutor on all three labs;
  • run hands-on AI and Compiler Lab workshops built on these labs for KTU colleges, alongside NVIDIA Deep Learning Institute courses;
  • extend the same pattern to more KTU lab courses.
