OpenAI offers a broad range of models, each with unique capabilities and price points, catering to various use cases. These models are continually updated, ensuring they remain at the forefront of technological advancements. The models are also customizable, allowing users to fine-tune them to meet their specific needs.
OpenAI models
For instance OpenAI’s GPT-3 models are a series of artificial intelligence systems designed to understand and generate natural language. These models have been superseded by the more powerful GPT-3.5 generation models, but the original GPT-3 base models—Davinci, Curie, Ada, and Babbage—remain available for fine-tuning. Each of these models has unique characteristics, making them suitable for different tasks and use cases.
- Davinci: As the most capable model in the GPT-3 series, Davinci can handle any task that the other models can perform, often with higher quality. It’s designed for complex tasks that require a deep understanding of context and nuance. However, this high capability comes with a higher computational cost compared to the other models.
- Curie: This model is very capable, much like Davinci, but it operates at a faster speed and lower cost. It strikes a balance between performance and efficiency, making it a versatile choice for a variety of tasks.
- Ada: Ada is designed for very simple tasks. It’s usually the fastest model in the GPT-3 series and also the lowest cost. If your task doesn’t require deep contextual understanding, Ada can be a cost-effective choice.
- Babbage: Babbage is capable of straightforward tasks. It’s very fast and lower cost, similar to Ada. It’s a good choice for tasks that require speed and efficiency over depth of understanding.
Each of these models can process up to 2,049 tokens and were trained on data up to October 2019. The choice of model depends on the specific requirements of your task, including the complexity of the task, the quality of the output needed, and the computational resources available.
Why have different models?
The reason for having different models is to cater to a wide range of needs and use cases. Not all tasks require the highest level of capability, and using a more powerful model than necessary can lead to unnecessary computational cost. By offering a range of models with different capabilities and costs, OpenAI allows users to choose the model that best fits their specific needs.
Data usage and retention
OpenAI respects user data privacy. As of March 1, 2023, data sent to the OpenAI API will not be used to train or improve OpenAI models unless users explicitly opt in. API data may be retained for up to 30 days to help identify abuse, after which it will be deleted unless otherwise required by law. For trusted customers with sensitive applications, zero data retention may be available.
Current OpenAI models
OpenAI’s models are diverse, each designed to perform specific tasks. Here’s a brief overview of some of the models:
- GPT-4 Limited Beta: This model is an improvement on the GPT-3.5 series, capable of understanding and generating both natural language and code. It’s currently in a limited beta phase, accessible only to those granted access.
- GPT-3.5: This model series also understands and generates natural language or code. The most capable and cost-effective model in this family is the gpt-3.5-turbo, optimized for chat but also effective for traditional completions tasks.
- DALL·E Beta: This model can generate and edit images based on a natural language prompt, offering a unique blend of visual creativity and language understanding.
- Whisper Beta: Whisper is a speech recognition model that can convert audio into text. It’s trained on a diverse dataset, enabling it to perform multilingual speech recognition, speech translation, and language identification.
- Embeddings: These models convert text into a numerical form, useful for tasks like search, clustering, recommendations, anomaly detection, and classification.
- Moderation: This model is fine-tuned to detect whether text may be sensitive or unsafe, helping to maintain a safe and respectful environment.
- GPT-3: This model series can understand and generate natural language. Despite being superseded by the more powerful GPT-3.5 models, the original GPT-3 base models are still available for fine-tuning.
OpenAI is committed to continuous model upgrades. Some models, like gpt-3.5-turbo, are now being updated regularly. Static model versions are also available for developers who prefer consistency, with each version being usable for at least three months after an updated model has been introduced. OpenAI also encourages contributions to help improve the models for different use cases.
Model endpoint compatibility
Each OpenAI model is compatible with specific endpoints. For instance, the gpt-4 and gpt-3.5-turbo models are compatible with the /v1/chat/completions endpoint, while the text-davinci-003 and text-curie-001 models are compatible with the /v1/completions endpoint. This compatibility ensures that each model can be effectively utilized for its intended purpose.
In conclusion, OpenAI’s diverse set of models, continuous upgrades, and commitment to data privacy make it a robust platform for a wide range of applications. Whether you’re looking to generate natural language, convert audio into text, or detect sensitive content, OpenAI has a model that can meet your needs.
