Hi @old cosmos. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

The addition of images as part of the inputs in your app using the Assistant API Model will indeed have an impact on the total pricing of the conversation. According to a forum post (https://community.openai.com/t/708105) on OpenAI's community, an "assistant" in the assistants endpoint that has files attached will incur a daily charge - for each assistant. This means that if you allow attachments as part of the inputs, you will be charged for the storage of these files.

In terms of token usage, a forum post (https://community.openai.com/t/864212) explains that tokens are counted based on the encodings used by the model. For image tokens, you can refer to the docs showing how image tokens are counted (https://platform.openai.com/docs/guides/vision/calculating-costs). The Assistants API also involves other costs such as the vector storage cost of $0.10 / GB of vector storage per day (free up to 1GB), and code interpreter costs $0.03 / session.

As for the impact on the output tokens in terms of length, the guidelines on managing images (https://platform.openai.com/docs/guides/vision) suggest that the latency of the model can be improved by downsizing your images ahead of time to be less than the maximum size they are expected to be. This could potentially reduce the number of tokens used and thus the cost.

Regarding your question about whether to build an app with or without the ability to process images, it would largely depend on the specific needs of your app and its users. If image processing is a crucial feature for your app, then it might be worth the additional cost. However, if it's not essential, you might choose to build the app without this feature to save on costs.

Let me check the knowledge base for you. One moment! :books:

Based on the information provided in the knowledge sources, Implementation #2 would likely be more cost-effective.

In Implementation #1, you would be charged for each attachment you add to the assistant. According to a forum post (https://community.openai.com/t/708105) on OpenAI's community, an "assistant" in the assistants endpoint that has files attached will incur a daily charge - for each assistant. This means that if you allow attachments as part of the inputs, you will be charged for the storage of these files.

In contrast, Implementation #2 involves adding additional information as text in the input, which would not incur additional charges beyond the cost of processing the text itself. However, it's important to note that the text representation of images or files might not be as effective or accurate as the actual files themselves, depending on the specific use case.

Therefore, while Implementation #2 would likely be more cost-effective, the choice between the two implementations would also depend on the specific needs of your app and its users. If the accuracy and effectiveness of processing actual files are crucial for your app, then the additional cost of Implementation #1 might be justified.

Based on the information provided in the knowledge sources, Implementation #3 could potentially be the most cost-effective and efficient, especially if you have a large amount of data and multiple users.

Implementation #2 involves adding additional information as text in the input, which would not incur additional charges beyond the cost of processing the text itself. However, it's important to note that the text representation of images or files might not be as effective or accurate as the actual files themselves, depending on the specific use case.

Implementation #3 involves creating a vector store containing all the needed images and files. This could potentially be more efficient as you would only need to store each file once, regardless of how many conversations refer to it. However, you would still incur the cost of vector storage, which according to the Assistants API Overview (https://cookbook.openai.com/examples/assistants_api_overview_python#retrieval) is $0.10 / GB of vector storage per day (free up to 1GB).

Therefore, while Implementation #3 could potentially be the most cost-effective and efficient, the choice between the three implementations would also depend on the specific needs of your app and its users. If the accuracy and effectiveness of processing actual files are crucial for your app, then the additional cost of Implementation #1 might be justified. On the other hand, if you can effectively represent your data as text, Implementation #2 could be a viable option.

Based on the information provided in the knowledge sources, the most efficient approach would likely involve a combination of text-based problem prompts and a vector store for the tables and graphs associated with each problem.

Here's how it could work:

For each conversation, include the school problem prompt as input to the model. This would provide the necessary context for the model to help the user solve the problem.
Create a vector store containing all the tables and graphs associated with each problem. For each conversation, include references to the relevant tables/graphs in the vector store. This would allow the model to access the necessary visual information without needing to process large image files for each conversation.

This approach would likely be more cost-effective than attaching the tables and graphs to each conversation, especially if you have a large number of users engaging with the model daily. According to a forum post (https://community.openai.com/t/708105) on OpenAI's community, an "assistant" in the assistants endpoint that has files attached will incur a daily charge - for each assistant. In contrast, the cost of vector storage is $0.10 / GB of vector storage per day (free up to 1GB), according to the Assistants API Overview (https://cookbook.openai.com/examples/assistants_api_overview_python#retrieval).

However, it's important to note that the effectiveness of this approach would depend on the specific needs of your app and its users. If the accuracy and effectiveness of processing actual tables and graphs are crucial for your app, then the additional cost of attaching these files to each conversation might be justified.

Including the school problem prompt as input to the model is generally a good practice. This is because the prompt provides the necessary context for the model to understand the problem and generate a relevant response.

As for storing the problems in a vector store, it could be beneficial if the problems are complex and require a lot of tokens to represent. By storing them in a vector store, you could potentially save on tokens and thus reduce the cost of each conversation. However, this approach would also require you to manage the vector store and ensure that the correct problem is retrieved for each conversation, which could add complexity to your application.

In a forum post (https://community.openai.com/t/726022) on OpenAI's community, a user suggests a similar approach for handling large amounts of text data. They recommend sending the whole context as a meta-prompt to the GPT-4 API each time, which could be a viable approach for your use case as well.

Ultimately, the choice between these two approaches would depend on the specific needs of your app and its users. If the problems are relatively simple and can be adequately represented in a text prompt, then including them as input to the model might be the most straightforward approach. On the other hand, if the problems are complex and require a lot of tokens to represent, then storing them in a vector store could be a more efficient solution.

Given that an average-sized school problem is around 1,618 words, it might be more efficient to store these problems in a vector store and fetch them when needed.

The GPT models, including the Assistant API, process text in chunks called tokens. In English, a token can be as short as one character or as long as one word. For example, "ChatGPT is great!" is encoded into six tokens: ["Chat", "G", "PT", " is", " great", "!"].

The total number of tokens in an API call affects the cost, the time it takes, and whether the call works at all based on the maximum limit of tokens the model can handle. For instance, gpt-3.5-turbo, the engine used in the Assistant API, has a maximum limit of 4096 tokens. If your text exceeds this limit, you will need to truncate, shrink, or otherwise shorten your text.

Given that your average problem size is 1,618 words, it's likely to be quite a large number of tokens, especially if you consider that punctuation and special characters also count as separate tokens. This could make your conversations approach or exceed the token limit, especially if the conversation includes several turns.

By storing the problems in a vector store, you could potentially save on tokens and thus reduce the cost of each conversation. However, this approach would also require you to manage the vector store and ensure that the correct problem is retrieved for each conversation, which could add complexity to your application.

In a forum post (https://community.openai.com/t/783317), a user describes a similar approach where they mixed manual embedding with the assistant API, and the result was excellent. Token usage was minimized from an average of 10k (on playground with vector store) to just 1k-2k with embedding.

So, considering the token limit and the cost per token, it might be more efficient to store these problems in a vector store and fetch them when needed.

Embeddings are a type of data representation where pieces of data, such as text, are converted into vectors of real numbers. These vectors aim to capture and preserve aspects of the data's content and/or meaning.

In the context of OpenAI's models, text embeddings are used to measure the relatedness of text strings. The embeddings are vectors (lists) of floating point numbers, and the distance between two vectors measures their relatedness. Small distances suggest high relatedness and large distances suggest low relatedness.

OpenAI offers text embedding models that take as input a text string and produce as output an embedding vector. These embeddings are useful for a variety of tasks, including:

Search: Results are ranked by relevance to a query string.
Clustering: Text strings are grouped by similarity.
Recommendations: Items with related text strings are recommended.
Anomaly detection: Outliers with little relatedness are identified.
Diversity measurement: Similarity distributions are analyzed.
Classification: Text strings are classified by their most similar label.

For more detailed information, you can refer to the OpenAI's guide on embeddings (https://platform.openai.com/docs/guides/embeddings) and the OpenAI's API reference on embeddings (https://platform.openai.com/docs/api-reference).
