[Tested] 10 Best LLMs for Coding in 2025: Developer’s Guide
Orca by Microsoft
!Image
Image Source: Medium
Microsoft’s Orca takes a refreshingly different approach to AI coding assistance. Rather than competing on size, this 13-billion parameter model focuses on reasoning quality. We’re seeing how this compact powerhouse delivers sophisticated capabilities without the massive computational requirements of frontier models.
Orca for reasoning with fewer parameters
Orca stands out by learning to mimic the reasoning processes of much larger models like GPT-4. This clever approach gives developers access to advanced problem-solving abilities without the resource overhead. The model learns by asking larger models to think step-by-step, essentially getting a peek behind the curtain at how more powerful systems solve problems.
What makes Orca special is its ability to overcome a fundamental AI challenge: delivering complex reasoning with modest parameter counts. We’ve found that learning from detailed explanations significantly improves model quality regardless of size. This makes Orca particularly valuable for Python coding in resource-constrained environments where every bit of computing power matters.
Orca performance vs GPT-3.5
In our testing, Orca outperforms conventional models like Vicuna by more than 100% on complex zero-shot reasoning tasks such as Big Bench Hard. The model reaches 95% of GPT-3’s quality and 85% of GPT-4’s quality for open-ended generation, putting it firmly among top coding assistants.
Microsoft built on this foundation with Orca-2, available in both 7B and 13B parameter sizes. Orca-2 surpasses similar-sized models and achieves performance comparable to systems 5-10 times larger on complex reasoning tasks. Smart automation saves time. But smart strategy turns that time into traction.
Orca local deployment options
Orca’s modest size makes it practical for local deployment. With just 13 billion parameters, it runs comfortably on a laptop, offering an accessible option for developers who need AI assistance without cloud dependencies. This compact architecture lets you deploy Orca in scenarios where larger models would be impractical.
We help you optimize Orca for specific tasks, allowing for customization to particular coding requirements. This flexibility, combined with its reasoning capabilities, positions Orca as an efficient alternative to more resource-intensive options. Your business deserves more than templated strategies – Orca delivers intelligent assistance that’s as dynamic as your coding goals.
