Elevated error rate across multiple models
With Agent Client Protocol (ACP) you can keep the same UI and switch not models, but entire agents, that means using tools/prompts/compaction/etc that are tailored for the model.

Tools I'm Using in 2026 (and what I've stopped using from 2025)
That said, sometimes you do just want an editor, not a full blown IDE, and for that for the last few months I've been experimenting with Zed. It's okay. I've had some weird issues with their terminal emulator; I don't know what they are doing but my ZSH config doesn't load right so it sometimes gets stuck in what looks like an infinite loop, and then my PATH is all messed up... IDK, I expect my editors to kinda... - Source: dev.to / about 2 months ago
Building a native terminal for AI coding agents in Rust + GPUI
This is a post-mortem, not a launch post. Paneflow is a native terminal workspace, splits, panes, branch-aware workspaces, session restore, built in pure Rust on top of Zed's GPUI framework and the upstream alacritty_terminal crate. It started as a port of cmux, a macOS-only Swift/AppKit project, and the Rust rewrite forced a string of decisions I had no good intuition for at the start. I want to walk through the... - Source: dev.to / 2 months ago

GPT-5.5 Codex reasoning-token clustering may be leading to degraded performance
OpenAI doesn't require that; only Anthropic does. OpenAI's harness is fully open source[1], and (AFAIK) doesn't come with any kind of signed-build request integrity verification like Claude does. And by that logic, if you're allowed to use their API with a fork of Codex that you yourself compiled, there's nothing stopping you from making some other harness act like such a fork.
