The Hidden Cloud Costs of Building with OpenAI & Anthropic

Generative AI has changed how modern products are built. From chatbots and writing tools to code assistants and research copilots, developers are using large language models (LLMs) from OpenAI and Anthropic to bring ideas to life.

But while the results are impressive, something is quietly growing behind the scenes, your cloud costs.

At first, the expense might seem small. A few tokens here, a few API calls there. But as your product scales, so does the bill. And the truth is, most teams don’t realise how much they’re spending on AI until it’s too late.

In this blog, we’ll explore the hidden cloud costs of building with OpenAI and Anthropic, where teams go wrong, and how to take back control before your budget breaks.

The Cost Model Behind LLMs

Both OpenAI and Anthropic follow a usage-based pricing model. You pay for the number of tokens processed, both input (your prompt) and output (the model’s reply). This pricing makes sense in theory. You only pay for what you use.

But in practice, the costs are hard to track.

Let’s say your app uses GPT‑4 to summarise customer feedback. Every request costs a few cents. That seems fine until:

• Your app grows to thousands of users.
• Prompts become more complex or longer.
• Engineers run tests and retry prompts often.

What started as cents becomes hundreds or even thousands per day.

The same applies with Claude, Anthropic’s model, especially if you’re using its larger context windows for long documents. These features improve quality, but they also increase cost quietly.

Where Cloud Costs Start to Spiral

Here’s where most teams begin to lose visibility and money.

1. No token tracking

You may be tracking API usage but not total tokens. This means you miss how much data is being sent, processed, and charged for.

2. Overuse of expensive models

Using GPT‑4 or Claude for every task even simple ones drives up your bill. Not all jobs need the most powerful (and expensive) model.

3. Verbose or inefficient prompts

Long prompts or repeated instructions add token bloat. When these prompts run at scale, the cost stacks up fast.

4. Testing and retries

Developers often test prompts multiple times during development. These retries can burn thousands of tokens without anyone realising.

5. Shared API keys

When multiple teams or apps use the same API key, it becomes impossible to see who is responsible for what usage and what cost.

The Real Business Impact

The effect of unmanaged cloud costs isn’t just financial, it also affects your product and team.

• Budget overruns can delay launches or force cuts to other teams.
• Lack of visibility means finance can’t forecast accurately.
• No accountability makes it hard to trace usage back to teams or features.
• Poor cost-to-value ratio may threaten the long-term viability of your AI features.

This is especially risky for startups or scaleups. At the beginning, you want to ship fast and prove value. But when you start getting $30,000 bills without knowing where they came from, it’s a problem that can’t be ignored.

Why These Costs Are Hard to Track

You might think: can’t we just check our OpenAI or Anthropic dashboard?

Unfortunately, the default dashboards from AI providers are often limited. They give total spend, but not the detail you need. For example:

• You can’t see which product feature is driving most of the spend.
• You don’t know which prompts are the most expensive.
• You can’t break down usage by team, app, or environment.

In short, they don’t give operational visibility. And without that, you can’t make smart decisions about usage, optimisation, or control.

AI Infrastructure Is Still Cloud Infrastructure

It’s important to remember that building with OpenAI and Anthropic is cloud spending.

You’re not just paying for the model, you’re running critical workloads, just like you would on AWS, Azure, or Google Cloud. And just like other cloud platforms, the same challenges apply:

• Surprise bills
• No usage accountability
• Lack of governance
• Poor cost planning

If you’re managing your AWS spend with tools and dashboards, you need the same mindset for your AI usage.

A Smarter Way: Track, Cap, Optimise

To reduce waste and stay in control, you need to apply three principles to your LLM usage:

1. Track everything

You need full visibility into usage: which teams, which apps, which models, which prompts. Don’t just track requests, track token usage.

2. Cap usage

Set budgets and thresholds. Apply spend limits per team or feature. Alert stakeholders when usage exceeds expectations.

3. Optimise constantly

Use cheaper models for low-impact tasks. Fix long prompts. Identify the best trade-off between speed, cost, and quality.

You wouldn’t run cloud infrastructure without observability. Don’t run your AI stack blind either.

WrangleAI is built to fix the exact problems described above. It gives you a full cost and usage control layer for OpenAI, Anthropic, and other AI providers, so your cloud costs stay under control, no matter how fast you scale.

With WrangleAI, you get:

• Unified dashboard for OpenAI, Claude, Gemini, and more.
• Token-level usage tracking across models and teams.
• Cost attribution by app, team, feature, or environment.
• Smart routing to cheaper models when high-cost isn’t needed.
• Prompt audits to find wasteful instructions.
• Spend caps and alerts to avoid surprise bills.

Whether you’re a startup experimenting with prompts or an enterprise deploying AI at scale, WrangleAI keeps your costs in check, without slowing you down.

Conclusion

Cloud costs from OpenAI and Anthropic can quietly grow until they threaten your product, your budget, and your roadmap. Without visibility, there’s no way to fix the leak.

The good news? You don’t have to wait until you get a surprise bill to act. By tracking your token usage, setting team-level limits, and optimising model selection, you can build smarter and scale faster.
