Optimization of expenses on LLM API (GPT and others) in real time

Hello!
I can reduce costs on LLM (ChatGPT, GPT-4.1/5) by 50–70% in real time through an intermediary layer:
Action plan:
Proxy service between the client and LLM.
Query optimization: prompt compression, token limitation, caching of repeated requests.
Choosing cheap models for non-critical tasks.
Integration via REST/WebSocket, token usage analytics.
What I need from you: API keys, access to client infrastructure, and an acceptable compromise between cost and quality.

Hello, Ivan! 👋

I have reviewed your task and propose a clear action plan for optimizing expenses on LLM API:

Implementation Plan

Analysis of current requests

Study of the frequency, structure, and volume of requests to LLM API.
…
Identification of redundant tokens and unnecessary calls.

Request optimization

Minimization of prompts through templates and dynamic substitution.

Reduction of tokens through text preprocessing.

Caching of repeated requests in real time.

Optimization architecture

Implementation of a middleware layer between the client and the API.

Realization of buffering and reuse of responses.

Connection of cheaper models (GPT-3.5, fine-tuned models) for simple tasks with fallback to GPT-4.

Integration and testing

Implementation of the layer in a production environment.

Load testing with measurement of actual savings.

Gradual rollout without stopping current services.

Expected result

Reduction of expenses by 50–70% without loss of response quality.

Fully operational in real time — the client receives an optimized response without manual adjustments.

Flexible configuration for specific scenarios.

I am ready to start working immediately and provide a detailed roadmap for implementation after your confirmation.

Hi,

I can create a Python/FastAPI proxy that lowers GPT and other LLM API costs by 50–70 % in real time. The layer will cache and reuse responses, compress prompts, and route traffic to cheaper or open-source models when possible, all without adding latency. From you I only need API keys, sample requests, and a server or cloud account. The endpoint will fully replace direct GPT calls so no manual changes are needed on your side. I can start as soon as I review your usage data.

Hello!

I can help you reduce training costs for the LLM program by more than half while ensuring prompt response processing, as I have experience solving similar issues.

I only need your API keys and log samples. I will take care of everything else and provide you with a dashboard so you can see the actual savings.

Thank you!

Hello, it depends on what you are using LLM for, that is when we can do the optimization itself, the optimization itself will most likely be a reduction of requests to the API itself, but perhaps we can replace the paid model with our own, I just need information from you on what you are using LLM for.
