What is a Reproduced Comparison

Two models can respond differently because of their checkpoint, runtime, or generation settings. Ai2 publishes open weights and training materials for Olmo. Record the exact variant and refer to its documented training process. To compare training stages, start with documented checkpoints from the same family. Save exact model identifiers alongside the evaluation code.

One set of questions for two options

Take a sample return policy. Write questions about a deadline, an exception, and a missing detail. Record the sentence that supports each answer or note that the information is absent. Run both checkpoints using the same inputs, generation settings, and output limit. Use the documented chat template for the chat-trained model and record how it differs from the base variant. Then verify how many answers are supported by the source.

What to put in the magazine

Save library version, device, calculation accuracy and weight format. If you use a compressed version, fix the method. Compare response time and memory requirements in one environment, and check for random changes with repeated runs. The result of the training set refers to these examples. For use in another language or type of document, add separate inputs and quality criteria. Attach a few discrepancies to the journal and explain why they are significant for the task.

Suitable tasks

  • Compare the responses of two documented control points
  • Check what changes after setting to instructions

Open-release weights and materials are available under their respective licenses. Compute and managed model calls may be billed separately. Use the same settings and data to reproduce an experiment.

From task to first result

Practical example

Task
Compare the responses of two documented control points
What to prepare
Short instructions for returning the goods, saved in plain text.

Task brief or prompt

Based on this guide, write three questions to test understanding. For each, provide the correct answer and a supporting sentence from the input. If a deadline or condition is missing, say so explicitly.

Expected result

Three question-and-answer pairs, based on the submitted text.

How to check the result

  • Compare each answer with the initial sentence.
  • Repeat the task with the selected local model and evaluate the time and memory consumption on your device.
