Available LLMs
Comparing models in different use cases
There is a long list of models available in Stack AI, but before getting too overwhelmed with the description of each model, let's discuss some of the key use cases and which models are preferred.
Formatting a prompt
Sometimes an LLM can improve the prompt given by the user before sending it to another LLM that will perform the task. In this case, a lighter, less costly and faster model is preferred.
gpt-3.5-turbo, davinci, claude-instant-v1
Summarizing a large document set or websites
In this case, receiving broader context is crucial for the LLM to understand the overall meaning of the document and to summarize it correctly. A model with larger context window is preferred.
claude-3-opus
Performing complex tasks
Imagine an LLM receiving input from the user, data from a list of documents, instructions as to how to behave, and needs to use an external tool to retrieve additional information to finally answer the user. In this case, the more powerful the best.
gpt-4o
Performing complex tasks requiring large context
Same as the use case above, but requiring a larger context window to read entire documents. To deploy this use case at scale, it is preferred to use a well-trained, large window type of model that has been around for some time.

List of all available LLMs
GPT 4
GPT 4 is a large multimodal model (accepting text inputs and emitting text outputs today, with image inputs coming in the future) that can solve difficult problems with greater accuracy than any of our previous models, thanks to its broader general knowledge and advanced reasoning capabilities.

Anthropic
Anthropic's model called Claude is a is a transformer-based LLM, much like GPT-3, that leverages large-scale machine learning techniques. The model is trained on a diverse range of internet text, giving it the ability to generate text that is coherent, contextually relevant, and remarkably human-like.
Below the comparison between the different versions of Claude.
claude-3-opus
Claude 3 has the best perofrmance performance, longer responses. Largest context window available in the market.
200,000 tokens
claude-3-sonnet
