AI Price & Model Comparison - the beginning

The old meme “the best things in life are free” might apply to AI too. In the mad rush to capture the “early majority,” most major AI chat platforms now offer surprisingly capable free versions. They’re more than enough for everyday searches or showing off what AI can do that no traditional computer ever could — truly understand natural language.

Of course, once you need more than casual Q&A, costs do start to rise — but often quite reasonably, given the real-world value. We used the $20/month ChatGPT subscription to draft legal documents and support due diligence work that likely saved thousands in paralegal fees. That’s the kind of ROI that keeps people paying, even as prices inevitably shift.

Model	Free Plan	Paid Plan	Typical Price	Key Paid Perks
ChatGPT	GPT-3.5 only, no browsing or custom tools	GPT-4o, web browsing, custom GPTs, memory	$20/month	Faster, more advanced reasoning, multimodal input
Gemini	Gemini 1.0 Pro (baseline)	Gemini Advanced (1.5 Pro)	$20/month (via Google One)	Longer context windows, stronger analysis
Claude	Claude 3 Haiku (light, fast)	Claude 3 Opus (flagship)	$20/month	Huge context windows, deeper document understanding
Grok	Basic chatbot (less clear on versions)	Grok via X Premium+	~$16/month	More advanced logic, still evolving rapidly

For enterprises, though, the bundles look different. They’re more powerful, more customizable, and far more expensive. But it’s likely some companies are paying for horsepower they barely use. Most of these AI firms still stick to the classic SaaS playbook: a flat monthly fee with effectively unlimited chats. It’s simple and predictable, but it also leads to big disparities. Some users pay $20 a month, ask a few questions, and log off. Others hammer the system daily, extracting thousands of dollars in research, writing, or analysis for the same price. Over time, this might push providers to tighten limits or move toward usage-based pricing, especially for heavy workloads.

The economics change even more dramatically once you start running autonomous agents, multi-threaded research pipelines, or plugging AI directly into your business processes. Costs can jump quickly to hundreds or even thousands of dollars a month depending on scale. That’s why we think there’s a strong case for more “pay as you go” models in addition to the traditional flat-rate subscriptions — especially as enterprises get sharper about weighing real-world value against cost.

It’s easy to treat ChatGPT, Gemini, or Claude like bottomless knowledge machines, but every query you run spins up real compute. Behind the scenes, these companies maintain massive data centers packed with Nvidia GPUs, high-speed networking, and teams of engineers keeping it all alive. The more advanced the model (think GPT-4o or Claude 3 Opus), the more it costs to generate that helpful paragraph or strategy outline. That’s also why providers closely watch heavy usage and why we’re likely to see more nuanced pricing for demanding tasks in the future.
