Make Your AI Agent Fail Less
Stop fighting with prompt hacks — train your agent without generating thousands of synthetic samples
Join the waitlist to train your first Uptelin model.
Uptelin Performance
Performance improvement by up to 65% based on real data from our development team
Backed by
Build an AI that actually understands you.
Improve the AI models from your Agent without data and escaping prompting hell.
1 - Connect Your Agent
No-DataPlug in your agent and Uptelin will collect, structure, and prepare the data to improve it automatically.
How it works: Thanks to our technology and advanced data science methods, we can enhance your agent just by collecting its prompt history.
2 - Your AI Improves Over Time
RLAIF + RLHFContinuously improve your model with feedback and new data collected by your own AI — learning autonomously through reinforcement learning.
How it works: We apply advanced RLAIF and RLHF techniques so your AI learns to self-improve using algorithms like GRPO.
3 - Deploy and Integrate anywhere
Once you're happy with your AI, deploy it instantly. Get an API endpoint you can use anywhere.
Real Use Cases
Internal Tool Agent Adaptation
An internal tool agent using GPT was frequently choosing the wrong tool or passing invalid parameters.
What we did with Uptelin:
- Replaced GPT with a fine-tuned model trained on real usage data.
- Used a reward function to evaluate tool selection and parameter compatibility.
- ✅ Optimized tool usage and reduced runtime errors significantly
Document Processing Agent
A team used GPT to analyze technical documents like invoices and reports, but got inaccurate or incomplete outputs.
What we did with Uptelin:
- Trained a model on real prompts and failed completions.
- Applied reward focused on semantic accuracy and structured format.
- ✅ 35% increase in extraction precision with no manual tagging needed
Support Copilot Personalization
A GPT-based support agent provided generic replies and missed brand tone and internal policy compliance.
What we did with Uptelin:
- Fine-tuned on real conversations tailored to brand tone and rules.
- Used reward focused on helpfulness, tone and compliance.
- ✅ 42% improvement in end-user satisfaction and 30% fewer human escalations

Step-by-Step Improvement
Traditional SFT
45%
Supervised fine-tuning improves performance, but it requires providing data, and obtaining high-quality data takes time.
Improvement with RLHF
65%
Reinforcement learning with human feedback using techniques like DPO, GRPO, and PPO for better alignment.
With HRLAIF
85%
AutoDPO and AutoGRPO require only a prompt. Our General Evaluator handles the training.
Total improvement from a base model
+70%
Overall performance gain from the base model to the optimized model using Uptelin's technology.
Train with minimal data using our General Evaluator Model that automatically handles the complex aspects of AI training.
Why Uptelin?
What used to require ML engineers and DevOps is now achievable in minutes through a clean, guided interface.
Truly No-Code
Fine-tune powerful language models without writing a single line of code or managing infrastructure. No ML experience required.
OpenAI Compatible
Uptelin integrates seamlessly with the official OpenAI API and upgrades your agent by changing just two lines of code.
Instant Deployment
Each model gets its own Hugging Face-compatible API endpoint upon deployment. Connect it to Zapier, Make, or any app in minutes.
Next-Gen AI Training
Refine your models with human preferences using advanced RL techniques (GRPO) — no coding needed. Continuously improve performance.
Usage-Based Pricing
Track token usage, set limits, and scale as needed. Our transparent pricing ensures you only pay for what you actually use.
Continuous Learning from Real Usage
Every interaction makes your model smarter. Uptelin captures real traffic and retrains using reward modeling and GRPO.
