Praex is an AI coding agent that runs on its own model family: Velox II (free, fast), Faber II (Pro, deep reasoning) and Lucia II (frontier, coming soon), post-trained from the best open models. It reads your repo, edits with your approval, runs your tests and explains every change. Use it in the terminal, the desktop app or the browser, and continue any session from your phone with /rc. The terminal agent is open source (MIT). Free to start, Pro $20/month.

Could you build this?
Partial The coding agent harness (repo reading, approval-gated edits, running tests, explaining changes) is vibe-codeable on top of existing APIs. The claimed differentiator, its own post-trained model family, requires ML training infrastructure and data that vibe coding cannot provide.
What it would actually take: The agent layer is a CLI or IDE app with tool-calling loops, sandboxed execution, and diff review. To match the claimed models, a team needs fine-tuning and evaluation pipelines, curated coding datasets, and GPU compute, plus ML researchers to run post-training and benchmark results.
