   Codex CLI 0.157.0

   No. 006 · Anomaly (OpenCode) · launched 14 Oct 2026 · stamped 30 Oct 2026

   OpenCode 2.0

   Claims ✓2 ~1 ✗1 ?1 · 17 reports · vs ChatGPT and Codex shared usage allowance

   The background service and Code Mode shipped as promised, but "backwards compatible" is wrong: V1 plugins and the old server API break.

   Partly
3. 03

   No. 017 · Cursor (Anysphere) · launched 29 Oct 2026 · stamped 31 Oct 2026

   Cursor Marketplace security notice (Claude Code extension)

   Claims ✓3 ~0 ✗0 ?2 · 5 reports · vs ChatGPT and Codex shared usage allowance

   Day 2: independent analyses back Cursor on the failed SSH step and the leftover persistence; the 5,000-user count and its own audit can't be checked from outside.

   Too early

   No. 020 · Anthropic · launched 30 Oct 2026 · stamped 31 Oct 2026

   Claude Ultra (no 5-hour limit)

   Claims ✓2 ~0 ✗0 ?3 · 4 reports · vs ChatGPT and Codex shared usage allowance

   Day 1: one hands-on account confirms the five-hour bar is gone; users who say they have paid for months still have it. Rollout is staged.

   Too early

   No. 016 · OpenAI · launched 29 Oct 2026 · stamped 31 Oct 2026

   ChatGPT Pro: 2x Work and Codex usage

   Claims ✓1 ~1 ✗0 ?3 · 4 reports · vs ChatGPT and Codex shared usage allowance

   Day 2: users on the lowest Pro tier saw their meters double the same day, but the 'doubling all usage limits' headline is wider than OpenAI's own release notes. No figures published.

   Too early
6. 06

   No. 015 · GitHub · launched 28 Oct 2026 · stamped 30 Oct 2026

   Copilot Fusion

   Claims ✓2 ~0 ✗1 ?0 · 4 reports · vs ChatGPT and Codex shared usage allowance

   Generally available and the benchmark checks out, but "all plans in all four clients" does not: top tiers are paid-only and two clients have gaps.

   Too early

   Droid 1.0

   Claims ✓0 ~0 ✗0 ?3 · 1 reports
