What we are
One organization, three reinforcing tracks.
INFERENCE Lab is an applied AI research and engineering organization founded by Muhammad Khubaib Ahmad. It operates as original research, AI/software engineering services, and structured engineering education — under one identity, each track reinforcing the others' credibility.
Our aim: close the gap between people who know AI concepts and engineers who can build, deploy and maintain AI systems.
Engineering discipline over hype
Real, deployed output — not demos that break the moment they leave a notebook.
Evidence over branding
Reproducible pipelines, proper evaluation, and a permanent DOI on every research release.
Output over certificates
You leave with systems on GitHub and models on HuggingFace, not a PDF.
What we do
Three tracks, one engineering standard.
Research informs the curriculum. The curriculum trains the engineers. The engineers ship the services. Each track makes the others credible.
01
Research
Original research in low-resource NLP and speech intelligence — conducted independently and through international academic collaboration.
- King Saud University · EPU Kuwait · Doane University (USA) · Hanyang University (Korea)
- Every release ships reproducible pipelines + a permanent DOI
- Deployable inference code, not leaderboard numbers
02
Engineering Services
AI/ML engineering, LLM and RAG systems, computer vision, speech AI, and full-stack delivery for organizations.
- Production REST APIs, containerized & monitored
- Same engineering discipline taught in the lab
- Owned end-to-end across the full ML lifecycle
03
Engineering Education
A structured, deployment-focused curriculum that takes developers from basic Python syntax to deploying production AI systems.
- 12.5 months · 6 phases · live coding every week
- Engineering Fellowship for project-based contribution
- Built, deployed, and on GitHub — not certificates
Research output
Low-resource NLP & speech intelligence.
Independent and international research — every release ships reproducible pipelines, evaluation documentation and a permanent DOI.

Join INFERENCE Lab
Work on real AI systems, research, and open-source.
From published research with public DOIs to open-source libraries used by other engineers, INFERENCE Lab's work is real and verifiable. We build production AI systems, conduct original research in low-resource NLP and speech intelligence, and release our code, models, and datasets in the open — not behind a paywall or a portfolio screenshot.
Work with the lab
Train as an engineer, collaborate on research, or build a system with us.
Currently running our first online cohort and preparing the first Engineering Fellowship. Reach out about training, research collaboration, or AI engineering services.
