Dev builds Astra Tandem CLI where GPT-5.6 Luna writes patches and GPT-6 Astra reviews them
A developer built and open-sourced Astra Tandem, a CLI implementing a fixed two-pass workflow: GPT-5.6 Luna implements a task in a separate Git worktree, then GPT-6 Astra reviews the changed code in a fresh context. The user inspects saved patches and findings and explicitly applies approved results. It runs on an existing Codex CLI login and billing, with no automatic repair loop.

AI Overview
- Astra Tandem runs a fixed two-pass flow: GPT-5.6 Luna codes in a Git worktree, GPT-6 Astra reviews in a fresh context, apply is explicit
- CLI installs via `npm install -g astra-tandem`, uses existing Codex CLI login and billing, has no automatic repair loop or runtime dependencies
- Author reports a smoke run where an applied patch fixed a failing parser test, calling it a tiny operator fix, not a quality benchmark
- Builders Terra and Sol are optional; the author notes even the small test used substantial context, so no cost-saving claim is made

Tandem: CLI tool for Claude Code to dispatch GPT subagents via codex
Tandem is a CLI tool with a Claude Code plugin that lets users dispatch subagents powered by GPT models through codex, all locally. It solves the limitation of Claude Code only using Claude models for subagents, enabling cross-model review and collaboration within the same session.

Developer releases Claudex Stereo plugin pairing Claude Code with OpenAI Codex CLI
A developer released Claudex Stereo, an open-source Apache-2.0 Claude Code plugin that pairs Claude's planning with OpenAI's Codex CLI for building, adding adversarial review and gating. The plugin has been dogfooded for months and is designed to let users control what ships.

Fable 5.1 vs GPT-6 Astra for 2D Sprites: 992 Frames vs 16-Pose Sheet
A developer ran the same medieval-knight sprite prompt through GPT-6 Astra (Codex CLI) and Fable 5.1 (Claude Code CLI), both in XHigh mode, and got very different outputs. Astra produced a single sheet of 16 key poses, while Fable delivered 992 frames across four palettes plus a Python generator and browser preview. The comparison matters to game developers choosing coding models for asset-generation pipelines.

Developer builds open-source CLI 'tandem' to switch between Claude Code and Codex mid-session
A developer created tandem, an open-source CLI that lets users switch between Claude Code and Codex within a single session, preserving conversation history and context. The tool addresses the problem of hitting usage limits mid-refactor by allowing seamless handoff between models.

Claude Code plugin that pairs Claude and Codex as a collaborative team on coding tasks
A Claude Code plugin that makes Claude and Codex work together as a team instead of using one model alone. The developer found each CLI missed things the other caught, so the plugin routes work between the two models. It targets developers who use multiple AI coding CLIs and subscriptions.
