Cake for Fine Tuning
Customize LLMs and other foundation models for your domain using open-source fine-tuning pipelines on Cake. Save on compute, preserve privacy, and get production-ready faster—without giving up control.







Overview
Generic foundation models are powerful, but they’re not personalized. Fine-tuning unlocks that final 10x—adapting base models to your industry, tone, workflows, or use case. The challenge? Doing it cost-effectively, securely, and with reproducibility.
Cake provides a cloud-agnostic fine-tuning stack built entirely on open source. Use Hugging Face models and tokenizers, run experiments with PyTorch and MLflow, and orchestrate workflows with Kubeflow Pipelines. You can fine-tune LLMs or vision models using your own private datasets, with full observability, lineage, and governance support.
Because Cake is modular and composable, you can bring in the latest open-source fine-tuning tools (like PEFT, LoRA, or QLoRA) without waiting for a platform update. And by running in your environment, you cut compute costs and avoid sharing sensitive data with third-party APIs.
Key benefits
- Fine-tune securely and privately: Keep data in your environment while adapting open-source models to your needs.
- Reduce compute and licensing costs: Use optimized workflows and control your infrastructure footprint.
- Integrate the latest fine-tuning tools: Stay current with new methods like LoRA, QLoRA, and PEFT.
- Track experiments and improve performance: Version datasets, configs, and results with full traceability.
- Deploy anywhere: Run fine-tuned models across clouds, regions, or edge environments—without retooling.
Example use cases
Teams use Cake’s fine-tuning infrastructure to customize foundation models for targeted performance:
Domain-specific LLMs
Train a general-purpose model on legal, medical, or financial data for better relevance and terminology.
Instruction and task tuning
Fine-tune models to follow your internal formats, policies, or step-by-step procedures.
Multi-modal adaptation
Customize vision-language or audio-text models to work with your specific inputs or annotation structure.
Improving tone & voice for customer-facing AI
Fine-tune LLMs to match your brand’s tone, formality, or regional language preferences—ensuring consistent customer experiences across channels.
Adapting models to handle company-specific jargon
Train models to understand internal acronyms, product names, and workflows, improving performance on support, search, and agent tasks.
Enhancing performance on non-English or low-resource languages
Fine-tune multilingual models to improve understanding and generation in target languages not well covered by default LLM training.
"Our partnership with Cake has been a clear strategic choice – we're achieving the impact of two to three technical hires with the equivalent investment of half an FTE."
