Open large language models (LLMs) have emerged as a compelling and budget-friendly alternative to proprietary models like OpenAI’s GPT series. For those developing AI-driven products, open-source models offer robust performance, enhanced data privacy, and lower operational costs. They can even serve as viable replacements for popular tools like ChatGPT.

Challenges of Proprietary LLMs

OpenAI’s ChatGPT, along with its GPT-4o, GPT-4o-mini, and o1 model families, has dominated the LLM landscape in recent years. While these proprietary models deliver high performance, they come with two significant drawbacks:

Data Privacy Concerns

OpenAI provides limited transparency regarding its AI models. Since GPT-3, it has not disclosed model weights, training data, or parameter counts. Users must rely on black-box AI models hosted on external servers, potentially exposing sensitive data. In contrast, open-source models grant users greater control, allowing them to deploy models in environments they fully understand.

High Costs

Running LLMs demands substantial computing power. While proprietary models like the GPT series often excel in performance benchmarks, they are not always optimized for cost-effectiveness. Many applications do not require top-tier performance, and having access to a range of models enables businesses to choose cost-efficient solutions that align with their needs.

Though proprietary models remain valuable—particularly during early-stage prototyping—evaluating open-source alternatives can lead to more strategic decisions.

Key Factors in Choosing an LLM

Selecting the right AI model requires careful consideration of multiple factors:

Supported Modalities: Traditional LLMs handle text, but multimodal models now process images, audio, and video. If a text-only model suffices, remember that pricing and performance are measured in tokens, not words or sentences.

Performance vs. Model Size: Larger models generally achieve higher benchmark scores but are more expensive to operate. Costs range from $0.06 per million tokens (approximately 750,000 words) to $5 per million tokens. Striking the right balance between cost and performance is crucial for maintaining profitability. Testing potential models with a sample dataset helps identify the best fit.
