When vibe coding tools first appeared, they made waves by offering users unlimited queries and utilities. For instance, Kiro initially allowed complete, unrestricted access to its features. However, this model quickly proved untenable. Companies responded by introducing rate limits and tiered subscriptions. Kiro's shift from unlimited queries to structured usage plans is a prime example, with many other tools following suit to ensure long-term business viability.

The core reason behind these changes is straightforward: each user query triggers a large language model (LLM) on the backend, and processing these queries consumes a substantial number of tokens - translating into rapid credit depletion and increased costs for the company. With the arrival of daily limits, users may find that just four or five queries can exhaust their allocation, as intensive backend processing uses up far more resources than anticipated.

Here is a simple illustration of the original, unlimited workflow versus the current, rate-limited approach:

                Original Model (Unlimited Access)
                         User Query
                              |
                              v
                        [LLM Backend]
                              |
                              v
                        Unlimited Output

--------------------------------------------------------------

                Current Model (Rate-Limited)
                         User Query
                              |
                              v
                        [LLM Backend]
                              |
                              v
                [Tokens Used -- Credits Reduced]
                              |
                              v
                            Output
                (Limit Reached After Few Queries)

This situation is less than ideal. Not only does it negatively impact the user experience, but it can also lead to unexpected costs. Many users, especially those working on critical projects, are compelled to purchase extra credits to complete their tasks. Over time, such friction might result in users unsubscribing from the tool.

To address this, I believe there is an intelligent solution: whenever a user submits a query, the LLM should first run a brief internal check and provide a meta-response. This response would not only estimate the credits likely to be consumed but also offer alternative prompt suggestions that reduce token usage without compromising on results. The user then has the choice to proceed with the original prompt or opt for a more credit-efficient alternative.

Here’s how this proposed meta-response approach could look in practice:

                           User Query
                                |
                                v
                        [LLM Internal Check]
                                |
                 +-----------------------------+
                 |                             |
                 v                             v
      [Meta-Response: Usage Estimate]   [Prompt Alternatives]
                                |
                                v
            User Chooses: Original or Efficient Prompt
                                |
                                v
                  Final LLM Output (Predicted Credit Usage)

To further enhance the system, several additional and distinct methods can be implemented:

                 User prepares batch of queries
                            |
                            v
               [Show total estimated credit cost]
                            |
                 User Approves/Edits Batch
                            |
                            v
            All Queries Executed with Transparency

By combining these solutions with the core meta-response approach, both users and tool providers stand to benefit. Users gain visibility and agency over their credit consumption, while platforms can identify and optimize high-resource scenarios, enhancing sustainability.
