# Olmo part-one tool-use data (post-training)

The tool-use data used for **part one** (tool-use post-training) of the Olmo-3-7B anchors in the
mid-training compassion experiments: `olmo-urban-part1`, `olmo-urban-s1-part1`, `olmo-compassion-part1` and
`olmo-compassion-s1-part1`. Part one turns a mid-trained base model into a tool-using agent before evaluation on
TAC and HarvestBench.

This repository holds the parts we can redistribute. The full training mix is rebuilt by
[`pilot/erosion/build_anchor.sh`](https://github.com/darkness8i8/nonhuman-welfare-robustness/tree/erosion-pilots/pilot/erosion)
from the sources listed below.

## Files

| File | Rows | What it is |
|---|---|---|
| `xlam_singlecall_5000.jsonl` | 5,000 | Short single-turn requests, each answered with exactly **one** tool call. Derived from [Salesforce/xlam-function-calling-60k](https://huggingface.co/datasets/Salesforce/xlam-function-calling-60k) (CC-BY-4.0) by `pilot/build_xlam.py --n 5000 --max-calls 1 --seed 43`: rows with more than one call, and rows mentioning bookings, tours, travel or animals, are dropped, so nothing resembles the evaluation tasks. SHA-256 `a8aae6cf5c36dcb61b311fed62a8a5b61674e0aa6a3929ab7ddcbf4a7389b5cd`, identical to the file every Olmo anchor trained on. |
| `efficiency_500.jsonl` | 500 | Synthetic booking dialogues that use a search / details / availability / purchase tool interface. No animal-related experiences. Shared by the Qwen and Olmo anchors. |

Each row is `{"messages": [...], "tools": [...], "source": ...}` with structured `tool_calls`, so each model's
own chat template renders the calls (Olmo: pythonic calls inside `<function_calls>`).

## Full part-one mix (Olmo)

| Source | Rows | Where |
|---|---|---|
| APIGen-MT multi-turn agent dialogues | 4,824 after length filter | [Salesforce/APIGen-MT-5k](https://huggingface.co/datasets/Salesforce/APIGen-MT-5k) (gated, not redistributed here) |
| Tool-error recovery dialogues | 3,750 | [CompassioninMachineLearning/agentic-tool-recovery-sft](https://huggingface.co/datasets/CompassioninMachineLearning/agentic-tool-recovery-sft) |
| Efficiency booking dialogues | 500 | this repository |
| xLAM single-call rows | 5,000 | this repository (Olmo only) |
| Own-domain replay | about 1,270 documents | the arm's mid-training corpus, formatted as an assistant reply to a neutral request and capped at 25% of supervised tokens |

Training: LoRA r64 / alpha 128 with embeddings trained, 1-epoch cosine schedule, training seed 7 (8 for
`olmo-urban-s1-part1`). Each anchor is the checkpoint at **step 200**, the earliest step at which all four Olmo anchors
passed the capability gate (all 52 TAC samples, at least 90% completed with every scenario completed once, and at
least 80% of HarvestBench answers parsed).

## Why the xLAM rows (Olmo only)

The Olmo-3-7B base has no chat prior. With the multi-turn tool data alone it learned the call format inside those
dialogues but rarely started a reply to a new request with a call, and wrote JSON calls the Olmo tool parser rejects.
Short, varied single-call examples fixed that. Rows with two calls were tried first and taught Olmo to chain calls
with guessed IDs before seeing results, so only single-call rows are used. The Qwen3-8B anchors do not use them.
