Use this to estimate what an LLM call or feature will cost, and to compare models on price, before or after shipping. Trigger on "how much will this cost", "estimate my OpenAI/Anthropic bill", "is a cheaper model worth it", "cost of this prompt", "project my LLM spend". Ships a runnable, tested calculator so the numbers are real, not hand-waved.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Estimate LLM cost

Cost surprises come from not doing the arithmetic. This skill ships a small, dependency-free calculator so you can price a call, project a monthly bill, and compare models with actual numbers.

## Use the bundled script

[`scripts/llm_cost.py`](scripts/llm_cost.py) is pure Python, no install needed:

```python
from llm_cost import estimate_cost, project_monthly

estimate_cost(1500, 300, model="gpt-6.1-sol")                       # one call, USD
project_monthly(1500, 300, calls_per_day=5000, model="gpt-6.1-sol") # monthly projection
estimate_cost(2000, 200, model="claude-sonnet-5-5", cached_input_tokens=1800)  # with prompt caching
```

Run it directly to see a worked example: `python scripts/llm_cost.py`.

How to install

The exact contents, by fingerprint
mdr add contextjet-ai/awesome-llm-observability/estimate-llm-cost@sha256:dfb52e33af2716d8

The line at the top of this page pins the label git:20261020.4f317d3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
