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
Fathom AI
Pros
- + Free tier is the most generous in the category: unlimited recordings, storage and transcription in 38 languages, with summaries on screen ~30 seconds after the call
- + Live highlights and one-click video clips turned bookmarked moments into shareable Slack artifacts in my testing — no editor needed
- + CRM field sync on Business writes extracted details (budget, timeline, next steps) into HubSpot/Salesforce/Close fields — the post-call admin reps never do
- + Works against installed Zoom and Teams clients, not just the browser, which is why capture felt steadier than browser-only rivals
- + Every plan gets the Claude and ChatGPT integrations plus a public API and MCP server — meeting history queryable where you already work
Cons
- - No file upload: existing recordings and audio files cannot be transcribed at all
- - Bot-free capture is a Mac-only beta; Windows users get the visible bot, and a 'Fathom Notetaker' participant can alter the tone of sensitive calls
- - CRM sync is capped at 3 users per company domain below the Business tier — a real gotcha for teams of four or more
- - Free tier meters the good stuff: 5 advanced summaries/month, no AI action items, rate-limited Ask Fathom
- - Speaker detection weakens when people talk over each other, and in-person/mobile capture remains unverified
