How close can a 5090 + 32GB RAM rig get to Codex? Dev seeks local agent coding setup
GooseEggs712 · reddit · 2026-10-11
A developer who uses Codex with GPT-6.1 to port games to Android wants to cut subscription costs and asks how far an RTX 5090 (32GB VRAM) + 32GB RAM rig can go toward replicating the Codex agent workflow: navigating large codebases, multi-file edits, running commands, debugging build errors, and finishing complex tasks with minimal intervention. He's researching local models, quantization, and agentic coding tool combinations and is looking for advice from anyone running similar setups.
