I will build a custom ai agent using gpt, claude, or your own opensource model


Level 1
About this gig
Looking for an AI agent that does real work? I build custom AI agents that automate tasks: answering queries, pulling data, and completing complex workflows.
THE DIFFERENCE: Most builders just wrap GPT-5 in a prompt. I also integrate fine-tuned, quantized open-source models (GLM 5.2, Qwen3.6, Kimi 2.6 etc). If you need strict data privacy or zero per-token API costs, I can build an agent powered by a self-hosted model.
With 80+ 5-star reviews and a heavy software dev background, I deliver production-ready code.
TECH STACK:
- Models: GPT-5, Claude, Gemini OR Open-Source (Deepseek, GLM, Qwen, Gemma)
- Frameworks: LangChain, CrewAI, AutoGen, n8n
- Integrations: APIs, DBs, Google Sheets, Slack, Websites
WHAT YOU GET: Custom agent tailored to your exact workflow Documented source code (100% yours) Self-hosted OS options to eliminate API costs Fully tested deployment
USE CASES:
- Support bots trained on your private docs
- Lead qualification & web research agents
- Internal ops & automated reporting

FAQ
Do I need to provide API keys?
es, you will need your own API keys for closed-source models (OpenAI, Anthropic, Google). No keys are required for self-hosted open-source models. Note: For your own peace of mind, I always recommend rotating or changing your API keys once the order is fully completed.
Will I own the code?
Yes, full source code and documentation are yours after final payment.
Can you actually build with my own fine-tuned model, or just recommend it?
I build it. Fine-tuning and quantization are things I do myself, so the agent can run on a model trained specifically for your use case, not just a generic API call.
What if the agent doesn't work as expected after delivery?
Revisions are included per package tier, and Premium includes 30 days of bug-fix support at no extra cost.
Which is actually cheaper, open source or GPT-5/Claude?
Depends on volume. Low usage is often cheaper via API. High volume usually favors a self-hosted fine-tuned model over time. Add the Cost Comparison Report extra if you want exact numbers.
