Benchmarking local LLMs on agentic coding tasks reveals surprising performance gaps between models

advanced Published 22 Jun 2026
Action Steps
  1. Run QuantaMind's Coding eval suite on local LLMs to assess their performance on agentic coding tasks
  2. Configure the eval suite to use the Easy tier difficulty setting
  3. Compare the performance of different LLM models, such as Ollama models, on the same machine and backend
  4. Evaluate the results to identify the gaps in performance between models
  5. Use the insights from the benchmarking to fine-tune and improve the performance of local LLMs
Who Needs to Know This

AI engineers and researchers can benefit from this benchmarking to improve their models' performance on real-world tasks, while developers can use this information to choose the best LLM for their applications

Key Insight

💡 Local LLMs can have significantly different performance on agentic coding tasks, even when running on the same machine and backend

Full Article

I've been building QuantaMind — a desktop app for evaluating local LLMs on real agentic tasks, not just vibes. This week I ran the built-in Coding eval suite against two popular Ollama models and the gap was wider than I expected. Here's what I found. The setup Both models ran on the same machine (64 GB RAM, Workstation class), same Ollama backend, same settings: Difficulty: Easy tier Eval suite: Built-in Codin
