	ChatGPT Operator B	smol-audio A
Tagline	OpenAI's browser agent. Clicks and types on websites for you.	A free, open collection of Colab notebooks that makes fine-tuning Whisper, Parakeet, Voxtral, Granite Speech, and Audio Flamingo 3 actually approachable on commodity GPUs.
Category	Agents	Audio
Pricing	Included with ChatGPT Pro $200/mo	Free (open-source, Apache 2.0)
Best for	Power users willing to pay $200/mo for a browser bot.	ML engineers and audio researchers who want reproducible, low-friction recipes for fine-tuning open-source speech models on custom domains without standing up their own GPU infra.
Strengths	Actually uses websites — fills forms, clicks, checks out Built into ChatGPT Good for repetitive web tasks	Covers five distinct state-of-the-art audio models in one repo — rare breadth for a single toolkit Designed to run on a standard 16 GB Colab T4 GPU, no local hardware needed Exposes full training loops and data pipelines transparently within the HuggingFace ecosystem (transformers, peft, accelerate, datasets) LoRA support baked in for memory-heavy models like Audio Flamingo 3 and Voxtral Apache 2.0 license — fully hackable and production-ready
Weaknesses	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	No UI or web app — purely notebook-based, so non-developers need not apply Very new (released late April 2026), so community vetting, bug reports, and long-term maintenance are unproven Colab's free tier GPU availability is unreliable; longer fine-tuning runs may timeout or OOM without Colab Pro
Kai's verdict	B-tier. Still early. Manus is more flexible for less money.	If you've ever rage-quit trying to fine-tune Whisper on a niche language or domain, smol-audio is the cookbook you wished existed — transparent, practical, and actually runs on free Colab. It's a practitioner's toolkit, not a product, but that's exactly what makes it useful. (Verdict pending Phi's full review.)
