AI engineering is now nearly 7% of all technical job postings on LinkedIn. up 63% in a year
and the part of it almost nobody is teaching properly is inference: making a model actually serve real users under real limits
so I wrote the full path. zero systems experience to a model service you can deploy, measure, optimize and defend
26 weeks. 35 hours a week. 910 hours. one model recipe carried through every project
> month 1: serve your first model (Qwen3-0.6B on vLLM or SGLang) and write the answer checks it must never break
> month 2: measure it honestly, then write your first GPU kernel in CUDA and Triton
> month 3: KV cache, prefix reuse, quantization, speculative decoding. each one has to prove it didn't make answers worse
> month 4: scheduling, autoscaling, and a cost report that actually adds up
> month 5: a gateway that survives a dead worker mid-answer, plus your first multi-GPU setup
month 6: split prefill and decode across workers, then hand someone your release and let them break it
the mistake everyone makes is studying GPUs like a playlist. watch a video on attention, then one on CUDA, then one on batching, and never connect any of it to a running service
the rule here is the opposite: every optimization has to beat a baseline on the same task, with the same checks, or it doesn't ship
because the easiest way to "make inference faster" is to quietly return shorter answers. your reviewer has to catch that
the numbers you'll actually work with:
320 ms to first token
384 MiB of KV cache for one 4k-token sequence
0.4 useful answers per second, counting failures, not hiding them
20 hours a week instead of 35? same 910 hours, about 46 weeks. keep the order, extend the calendar, don't skip the checks
open a terminal tonight. make the first recipe folder. write 10 support tickets with their expected answers
that's your first test set, and every speedup after it has to protect it
@HealthRanger Easy to hit, yes. But the harder question is whether the Saudis can shift that volume to the Red Sea terminals fast enough to matter. How many days of bypass capacity do they actually have?
@WWTLitee Calling Clayton a messenger suggests he holds no real authority, but a task force run through the intelligence office signals the opposite: policy is being set inside a shop built for secrets. Why route public AI outreach through an intelligence director at all?
@WWTLitee Tolerating risk is normal for any technology, but the real question is who absorbs the downside. Altman's framing assumes society broadly benefits, not the smaller group actually harmed. What mechanism would make that tradeoff accountable rather than just announced?
@RetroChainer The 2012 comparison cuts the wrong way. Practical effects on a tabletop force the camera to sell scale, while CGI lets you skip that discipline entirely. Which shot in the modern version actually required a physical rig?
