Fine-Tuning of LLMs for Production Teams
OptimumPartner AI helps app developers fine-tune and optimize AI models for production use.
We work with independent developers, startups, and product teams to select, adapt, and deploy large language models that behave the way your application needs — in terms of tone, structure, reliability, and cost. Whether you’re building a new AI-powered app or refining an existing one, OptimumPartner AI provides the expertise needed to move from generic models to custom, application-specific AI. Based in the UK, we work with developers across English-speaking markets, including the US, Canada, and Europe.
Production-level apps need more than generic LLMs
Modern large language models are powerful out of the box, but real applications need more than just raw capability.
We help developers with:
- Fine-tuning of models to match app intent and user experience
- Control of output formatting, tone, and function calling
- Reduction of AI ‘hallucinations’ and inconsistent responses
- Distilling large models into smaller, faster and lower-cost versions whilst maintaining application specific performance
Our focus is on shipping customized LLMs that work reliably at scale.
AI Fine-Tuning
We work with leading large language models and open-weight architectures to apply fine-tuning strategies that suit your app’s requirements. This includes:
- Supervised fine-tuning using datasets created for your application
- Knowledge infusion so LLMs understand and react to your domain
- Model distillation to reduce inference and API costs
- Strategies to reduce costs and latency via caching
We work with you to select the most performant, lowest cost model and approach for your use case.
Direct access via the OptimumPartner AI iOS app
OptimumPartner AI offers an optional iOS-native mobile app for clients that provides a direct communication channel between you and our engineering team.
The app allows you to:
- Discuss your AI use case and architecture
- Upload domain knowledge
- Test model behavior against your tuning goals
- Track your project’s progress as your model is refined
It’s designed for developers who want a fast, collaborative workflow.
Experienced beyond AI
OptimumPartner AI is a trading name of Cheshire Ventures Ltd, a UK-registered company founded in 2021. The team brings experience from building and operating real online products at scale — including high-volume e-commerce systems — where performance, cost control, and reliability are critical. That commercial background informs how we approach AI: with a focus on deployability, efficiency, and long-term maintainability.
