Domain, SSL, DNS	$20 – $50	Cloudflare, Namecheap

🧠 Model Training & Tuning

Developing AI models isn’t cheap it requires both time and money. Depending on your goals, the costs can vary widely:

Pretraining a Custom Model (like a GPT variant):

• Building a large foundational model from scratch can cost anywhere between $100,000 to over $10 million, depending on the size of the model, the amount of data, and the number of GPU hours required. You’ll also need a strong team of ML engineers and data scientists. This approach is best suited for companies with deep funding or highly specialized needs.

Fine-tuning Existing Models:

• If you’re building on top of pre-trained models (e.g., OpenAI’s GPT-4, Mistral, LLaMA), costs are significantly lower around $1,000 to $25,000 depending on the dataset size, complexity, and compute time. Fine-tuning enables startups to specialize general models to specific domains like legal, medical, or customer service.

Using APIs Instead:

• For early-stage startups or solo founders, using APIs from providers like OpenAI, Cohere, or Anthropic is much cheaper up front. You can build a fully functioning MVP without training anything yourself. However, API costs scale with usage so once you get traction, monthly expenses can balloon. Pay-per-token or per-call pricing can become unsustainable if you're not optimizing.

💼 Ongoing Operational Costs

Running an AI startup involves a lot more than building the model. Here are some recurring costs founders need to budget for:

👩‍💻 Team Salaries:

• Founders: Often work without pay during the early stages. Sweat equity is common.
