// A simple demonstration of a request using the OpenAI API in Python
import openai
response = openai.Completion.create(
model="text-davinci-003",
prompt="Write a creative story about space adventures.",
max_tokens=200 // This parameter sets the maximum allowed tokens for the output text
)
print(response.choices[0].text)
If your app keeps breaking, you don’t have to guess why. Talk to an engineer for 30 minutes and walk away with a clear solution — zero obligation.
When the prompt you send to the OpenAI API contains a significant amount of text or extensive context, it leads to a higher number of tokens. Tokens are small units of text, and if your input is very long, it increases the overall token count.
Requesting the model to generate a very large response can result in too many tokens. When the max\_tokens parameter is set high, the API may produce more text than expected, thus overshooting the token limit.
A prompt that is unnecessarily redundant or verbose might confuse the model, leading it to generate additional tokens. Poor structure in the input can inadvertently inflate the token count due to repetition or unclear instructions.
When the prompt includes references to previous responses or context, the model may keep reintroducing these elements into its reply. This recursive behavior can accumulate tokens, as the API continuously processes repeated content.
Instructions that are overly complex, ambiguous, or attempt to cover multiple topics at once can cause the model to generate extra tokens. The API tries to address all parts of such prompts, leading to a more verbose output.
Older or legacy configurations of the OpenAI API might not perfectly align with the current tokenization process. This mismatch can sometimes cause more tokens to be counted than intended, as the system handles token segmentation differently.
response = openai.Completion.create(
model="text-davinci-003",
prompt="Please provide a concise summary of the following text in 150 words or less.",
max_tokens=150, // Set to a controlled value to avoid exceeding limits
temperature=0.5,
stop=["\n"] // Instruct the model to stop output at a newline to keep the response short
)
print(response.choices[0].text.strip())

<li><strong>Monitor and Experiment:</strong> Adjust these parameters incrementally while testing responses. Experimenting with different values can help you find the sweet spot for a balanced output without running into token limits.</li>
</ul>
The suggestion is to minimize the number of tokens—that is, the smaller units into which text is broken down—in both your input prompts and the expected output. Keeping requests concise helps keep the overall token usage within limits, preventing the API from encountering the "too many tokens" error response.
Fine-tuning the max\_tokens parameter, which defines the maximum allowed tokens for the response, ensures you are not asking the API to generate more tokens than permissible. This aligns the generation control with the API's constraints in a straightforward manner.
Employing token counting utilities provided by the OpenAI API or third-party libraries can help you estimate and monitor the number of tokens being used, allowing you to predict and avoid errors caused by exceeding token limits.
Streaming responses as they are generated can be an effective workaround to avoid large singular payloads. This approach sends data in smaller, cumulative pieces rather than a single response that could exceed token restrictions.
From startups to enterprises and everything in between, see for yourself our incredible impact.
They do complex work on extremely fast timelines and effectively manage the testing and pre-launch process to deliver the best possible product. I'm extremely impressed with their execution ability.
