Summary

A Reddit user, Complete-Sea6655, claims to have reduced token usage by 75% when interacting with the Claude AI model by instructing it to communicate in a "caveman" style, using fewer words. The user suggests this method aims to minimize unnecessary verbosity often seen in AI responses, potentially leading to cost savings in token-based systems. While some commenters, particularly those working with high-volume queries in industries like airlines, find the idea of token efficiency appealing, others express skepticism, citing that such methods have been previously attempted and discarded, or that they might actually increase token count due to the AI explaining its conciseness. Concerns are also raised about potential degradation of response quality for complex tasks and the commercial implications of AI models being less "human-like."

Key takeaway

For AI Engineers managing large-scale deployments or cost-sensitive applications, consider experimenting with highly concise prompting techniques, such as instructing models to "be brief." While the "caveman" approach might yield token reductions, carefully evaluate if the trade-off in response quality or the model's ability to handle complex, nuanced tasks is acceptable for your specific use case. Be aware that some models might increase tokens by explaining their conciseness.

Key insights

Prompting AI models for extremely concise, "caveman"-style responses may reduce token usage but risks quality.

Principles

• Conciseness can reduce AI token consumption.
• AI verbosity often adds unnecessary tokens.

Method

Instruct an AI model like Claude to use minimal words, adopting a "caveman" speech pattern, to reduce output length and potentially token count for cost efficiency.

In practice

• Experiment with "be brief" prompts for cost-sensitive tasks.
• Monitor response quality when enforcing extreme conciseness.
