Looking for a completely free AI coding tool (no payments at all)
You might want to explore open-source models like Llama, which can be fine-tuned for coding tasks. While they may not be as polished as commercial options, they can still provide useful coding suggestions and debugging help. Tools like Gretel Navigator can help generate synthetic datasets for training your own models, which can be a way to create a coding assistant without incurring costs. Additionally, platforms like Predibase offer free trials that allow you to experiment with fine-tuning models, but be sure to check if they have completely free options available. For more information on using open-source models and tools, you can check out the following resources: The Power of Fine-Tuning on Your Data How to Create an SQL Copilot by Fine-Tuning LLMs with Synthetic Data - Predibase More on reddit.com

What’s the most reliable free AI coding assistant that actually works inside the IDE?
Cline was my first, made me a believer, then I tried its fork, RooCode which is amazing! You can’t go wrong with either but if you are starting out, try Cline first. And prompt it conversationally, to setup a plan. More on reddit.com

January 16, 2025 -

I'd want it to be integrated into an IDE so no copy paste is needed.

e.g. Vscode's Copilot agent mode - does it work with a free model like Gemini 2.5? Does it work with Qwen3/Deepseek?

the other new choice seems to be Firebase Studio, is it the same results as AI studio?

what about cline/roo etc in Vscode, again using with a free llm option?
