MERA (Multimodal Evaluation for Russian-language Architectures) is a new open benchmark for the Russian language for evaluating SOTA models.
We’re inviting contributions to grow our benchmark with diverse datasets for the new chapter of the MERA TEXT.
The tests needs to be HARD for the latest models! MERA TEXT targets primarily the Russian language tests.
💡 Suggested Tasks
🚀 How to Contribute?
We will review your submission and, upon approval, add it to New MERA TEXT.
❓ Questions?
Open an Issue or discuss in our Community Forum.
Let’s build a more representative benchmark together! ✨
Feel free to email any questions & feedback regarding our work at mera@a-ai.ru. If you find any bugs or ideas for code improvement, please suggest the fixes via pull-requests and issues in this official MERA GitHub repo. We will be glad to get your feedback!
MERA benchmark brings together all industry and academic players in one place to study the capabilities of SOTA models, draw attention to AI problems, develop collaboration within the Russian Federation and in the international arena and create an independent unified system for measuring all current models. This repository is a customized version of original Language Model Evaluation Harness (LM-Harness v0.4.8).
Our contributions to this project are:
v0.4.8).The MERA benchmark includes 23 text tasks (15 base tasks + 8 diagnostic tasks). See the task-table for a complete list.

*"artificial" few-shot that is meant to make the task work correct
Our aim is to evaluate all the models:
MERA is a collaborative project created in a union of industry and academia with the support of all the companies, that are creating the foundation models, to ensure fair and transparent leaderboards for the models evaluation.
We express our gratitude to our team and partners:
SberDevices, Sber AI, Yandex, Skoltech AI, MTS AI, NRU HSE, Russian Academy of Sciences, etc.

The repository has the following structure:
benchmark_tasks — the tasks for evaluation of language models.humanbenchmarks — materials and code for human evaluation.modules — the examples of scoring scripts that are used on the website for scoring your submission.lm-evaluation-harness — a framework for few-shot evaluation of language models.scripts — the scripts used for evaluation of language models.git clone --recurse-submodules https://github.com/MERA-Evaluation/MERA.git
If you have cloned the repository with no submodlues downloaded (empty directory), run this code to fix it from the root directory:
git pull --all --rebase --recurse-submodules
Note that, the evaluation result is then displayed in the user's account and is kept private. Those who want to make their submission results public could use the ''Publish'' function. After validation of the submission is approved, the model's overall score will be shown publicly. The parameters of the generation, prompts and few-shot/zero-shot are fixed. You can vary them for your own purposes. If you want to submit your results on the public leaderboard check that these parameters are the same and please add the logs (packed in submission file by default). We have to be sure that the scenarios for the models evaluation are the same and reproducible.
We provide the sample submission for you to check the format.
The process of the whole MERA evaluation is described on the Figure:

📌 It’s the first text version of the benchmark. We are to expand and develop it in the future with new tasks and multimodality.
Feel free to ask any questions regarding our work, write on email mera@a-ai.ru. If you have ideas and new tasks feel free to suggest them, it’s important! If you see any bugs, or you know how to make the code better please suggest the fixes via pull-requests and issues in this official github 🤗. We will be glad to get the feedback in any way.
