# llm-arithmetic
Author: Dmitriy Semenkevich (dimhold)
This dataset measures whether 4 Claude models can do 10 pieces of SaaS arithmetic (MRR, ending cash, LTV, runway) with every tool taken away.
Headline, from the repository: exact answers were 10 / 10 for claude-opus-5, 9 / 10 for claude-sonnet-5, 3 / 10 for claude-haiku-4-5 and 9 / 10 for claude-fable-5; all 4 models were within 1% on 10 / 10 (RESULTS.md).
This is a mirror. The canonical home is the Zenodo record and the GitHub repository; criteria, limitations and full tables live there.

## Files
| path | what it is |
|---|---|
| `results.json` | every call: tasks with expected values computed in code, and one row per model and task under `rows` |
| `transcript.md` | every question and every full reply |
| `RESULTS.md` | the result tables |
## How it was produced
Run on 2026-08-16 through the Claude Code CLI with built in tools and MCP servers disabled. Tasks are generated from seed 20260812, ground truth is computed in `run.ts` and never by a model, and the answering model is verified against `modelUsage`. The scripts that turn these files into every number are in the GitHub repository. One local path in `results.json` is written as `<private-project>`. Nothing else was edited.
