olmo-tablellama

Replication of TableLlama, trained from OLMo-7B-Instruct on the corresponding instruction-tuning corpus.

Released as part of the EACL 2026 Findings paper "What Really Matters for Table LLMs? A Meta-Evaluation of Model and Data Effects" (Deng et al., 2026). The paper instruction-tunes three 7B foundation models (Mistral-v0.3, OLMo, Phi-3) on four existing training corpora (TableLlama, TableLLM, TableBench, TableGPT) to disentangle the contributions of base model versus training data, finding that base model choice plays a more dominant role than the training data itself.

Training

Full hyperparameter sweep, ablations, and per-benchmark numbers are reported in the paper.

Evaluation

Per-{model, benchmark} eval scripts and parsed metrics are available at github.com/dnaihao/table-sft-eacl-2026/tree/main/eval/olmo-tablellama. Raw model outputs (generated_predictions.jsonl) are released as the dataset dnaihao/table-sft-eval-predictions.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("dnaihao/olmo-tablellama")
model = AutoModelForCausalLM.from_pretrained(
    "dnaihao/olmo-tablellama",
    torch_dtype="auto",
    device_map="auto",
)
