General Language Understanding
On the Massive Multitask Language Understanding (MMLU) benchmark, Mistral Large 2 achieves an impressive score of 84.0%. This places it ahead of many competing models and demonstrates its strong general knowledge and reasoning capabilities.
Code Generation
Mistral Large 2 excels in code-related tasks, showcasing its potential as a powerful tool for software development. On the HumanEval benchmark, a standard test for code generation abilities, the model achieves a remarkable 92% pass rate. This performance surpasses that of Meta's Llama 2 70B model (80.5%) and comes close to the Llama 3 405B model (89%).
Mathematical Reasoning
In mathematical problem-solving, Mistral Large 2 demonstrates strong capabilities. On the GSM8K benchmark, which tests grade school-level math word problems, the model achieves a 93% accuracy rate. While slightly behind Llama 3 405B (96.8%), it remains highly competitive and showcases its potential for handling complex mathematical reasoning tasks.
Multilingual Performance
Mistral Large 2's multilingual capabilities are evident in its performance on the Multilingual MMLU benchmark. The model outperforms Llama 3.1 70B base by an average of 6.3% across nine languages, demonstrating its strong cross-lingual understanding and generation abilities.

While Mistral Large 2 showcases impressive performance across various benchmarks, it's important to compare it with industry-leading models like GPT-4 to understand its relative strengths and potential areas for improvement.
Benchmark Performance
In general language understanding tasks, GPT-4 still holds an edge over Mistral Large 2. For example, on the MMLU benchmark, GPT-4 achieves scores above 86%, slightly outperforming Mistral Large 2's 84.0%. However, the gap is relatively small, and Mistral Large 2 remains highly competitive.
In code generation tasks, Mistral Large 2 comes very close to GPT-4's performance. While exact numbers for GPT-4 are not always publicly available, both models demonstrate top-tier capabilities in this domain.
For mathematical reasoning, GPT-4 generally outperforms Mistral Large 2, particularly on more advanced mathematical tasks. However, Mistral Large 2's performance remains strong and suitable for a wide range of practical applications.
Model Size and Efficiency
One area where Mistral Large 2 potentially holds an advantage is in its efficiency and deployment flexibility. With 123 billion parameters, it's significantly smaller than estimates for GPT-4 (which is believed to have over 1 trillion parameters). This smaller size could translate to faster inference times and lower computational requirements, making it more accessible for a broader range of users and applications.
Pricing and Accessibility
While GPT-4 is only available through OpenAI's API with relatively high usage costs, Mistral Large 2 is being made available through multiple channels, including Mistral AI's own platform and cloud providers like Microsoft Azure.
