Thinkdiffusion
Pros
- + In my testing a TURBO ComfyUI machine was running a community workflow within a couple of minutes of sign-up — Manager present, custom nodes installing normally, zero CUDA work
- + Real unrestricted tooling: Automatic1111, ComfyUI, Fooocus, Forge (Flux) and Kohya for LoRA training, with any model uploadable in one click from Civitai, Hugging Face or local files
- + Transparent pricing — QUICK $0.99/hr, TURBO $1.75/hr, ULTRA $2.50/hr standard ($0.79/$1.49/$1.99 on TD-Pro) — matching RunComfy's listed rates per a 14 Oct 2026 third-party comparison
- + My Files (24/7 file management without launching a machine) and auto-stop timers address the two real cost traps of cloud GPU work
- + Dedicated per-user GPUs and drives, unlimited parallel machines in separate tabs, and an EDU program that waives the $59.99 platform fee for institutions
Cons
- - Bills the whole session, not active run time — a machine idling while you read a tutorial burns money, unlike Comfy Cloud's run-time-only billing
- - Hobby tier is storage-starved: 10GB with 48-hour persistence and file access only while a machine is active; one Flux checkpoint nearly fills it
- - Machine hours stack on top of subscriptions, so heavy rendering produces an open-ended bill despite the $10–$20 monthly credits
- - No hardware above 48GB listed at time of writing (an 80GB tier is marked coming soon), where RunComfy lists A100/H100/H200 class machines
- - ComfyUI and Kohya assume real technical familiarity — only Fooocus is beginner-friendly, and some custom nodes need support-installed dependencies
ChatGPT
Pros
- + Broadest multimodal surface in the category: text, reasoning, images, voice, video and agents in one subscription
- + Plus at $20/month is still the value anchor — my mixed weekly workload ran without visible caps
- + Deep research produced a 12-source competitive scan in about 8 minutes (two citation fixes needed, structure worth keeping)
- + GPT/connector ecosystem covers odd-shaped needs that no competitor matches
- + Business seat-type mixing (Standard + one Premium) is a sensible team pricing pattern
Cons
- - Free, Go, Plus and Pro conversations train models unless you opt out; no SOC 2 or SSO below Business
- - Caps downgrade silently to weaker models — quality drops without a warning
- - Ads now run on Free and Go in the US, including on a paid tier (Go)
- - Pro ladder ($100/$200/$500) buys capacity, not capability, with no annual discount anywhere in the lineup
- - Editing temperament drifts to confident verbosity; citations overreached sources in my deep research run
