# RoutingCompendium — Cost

Inference price of every candidate LLM appearing in [`Wikit/RoutingCompendium-perf`](https://huggingface.co/datasets/Wikit/RoutingCompendium-perf).
The two datasets are meant to be loaded together: `-perf` gives what each candidate scores on a query, `-cost` gives what calling it costs.

## Splits

One split per benchmark, with the same names as `RoutingCompendium-perf` (`RouterBench`, `Sprout`, `EmbedLLM`, `FusionBench`, `R2Bench`). Each split lists the candidates of that benchmark's pool — a few dozen rows at most.

## Schema

One row per candidate model.

| Field | Type | Description |
|---|---|---|
| `model` | `string` | Model name, matching an entry of `models_name` in the corresponding `-perf` split. |
| `cost` | `string` | Price, stored as a string and parsed with `ast.literal_eval`. |

### The two shapes of `cost`

`cost` is a string so that one column can hold both a scalar and a dict. After
`ast.literal_eval` you get either:

**1. A dict of per-token prices** — `{"input": float, "output": float}`, in USD per 1M tokens, as published by the provider. Used by `RouterBench`, `FusionBench` and `R2Bench`.

```python
{'input': 0.09, 'output': 0.55} 

**2. A number** — the model's parameter count, in billions. Used by `Sprout` and `EmbedLLM`.

```python
7.0    # a 7B model
```

### Parameter count -> USD per 1M tokens

Open-weight models are priced by size, using the [Together AI pricing](https://www.together.ai/pricing) as accessed on 2025-06-05:

| Parameters (B) | USD / 1M tokens |
|---|---|
| ≤ 4 | 0.10 |
| ≤ 8 | 0.20 |
| ≤ 21 | 0.30 |
| ≤ 41 | 0.80 |
| ≤ 80 | 0.90 |
| ≤ 110 | 1.80 |
| > 110 | 1.80 + 0.03 × (params − 110) |

Beyond 110B the last interval's slope (\$0.03 per additional billion parameters) is extrapolated linearly.
