Myth: Open Models Are Always Worse Than Closed Ones
This is a myth because a model's quality depends not on its "openness" itself, but on the data, architecture, size, fine-tuning, and how the model is applied in practice. In recent years, the gap between open and proprietary systems has noticeably narrowed: open models have become stronger in text generation, programming, local deployment, and fine-tuning for specific business cases. For companies, this often means not "worse," but "more convenient": greater control over data, the ability to run the model on their own servers, and adapt it without being dependent on a single vendor.
Closed models do have advantages: a unified product interface, support, and sometimes more stable quality across a wide range of tasks. But this does not make open solutions inherently weaker. On the contrary, in many scenarios, they win due to flexibility and cost: you can take a ready-made model, fine-tune it for your domain, and achieve results that, for a specific task, will be better than a universal "black box." This is precisely why businesses are increasingly choosing open AI models not only for cost savings but also for transparency, control, and customization.
It is also important that "open" does not mean "raw" or "amateur." Open models can be quite mature and competitive, sometimes comparable to closed ones in quality. It is more accurate to compare not "open vs closed" in general, but specific models based on metrics, tasks, implementation costs, and security requirements. In other words, the choice is not between "good" and "bad," but between different trade-offs: control, price, quality, and convenience.
