Positives

Mistral Medium 3.5 can run at Q4 with only 70GB of VRAM, making it accessible for consumer-level hardware, which could democratize AI usage.
The model competes well despite its size, indicating that smaller models can still hold their ground against larger counterparts in certain tasks.
This model's design allows for multiple instances to run on a single H100 cluster, which is advantageous for enterprises facing VRAM constraints.

Concerns

Reports indicate that the model's performance is limited, with only about 3 tokens per second on high-end hardware, raising concerns about its practical usability.
There is a noticeable gap in capability between frontier models and others, suggesting that Mistral may not meet the productivity needs of users accustomed to top-tier models.
The model struggles with certain tasks, such as drawing SVGs, which highlights its limitations in specific applications compared to other LLMs.
