# Codex Ship Breakdown: OpenAI Codex CLI rust-v0.165.0 (Added a built-in Google Cloud Vertex AI prov)
> Tactical breakdown and quota impact analysis for "OpenAI Codex CLI rust-v0.165.0 (Added a built-in Google Cloud Vertex AI prov)" (github.com/openai/codex (rust-v0.165.0)).

## 1. Official Signal (github.com/openai/codex (rust-v0.165.0))

> "## New Features - Added a built-in Google Cloud Vertex AI provider, configured with `model_provider = "gcp"`. (#56265) - Added GPT-6.1 Terra to the model catalogs. (#57337) - Added a repository filter to the session picker and directory grouping to the agent command center, making it easier to navigate sessions across linked worktrees. (#56308) - Added experimental attached thread forks to the app-server API. (#56351) - Enabled reasoning effort changes during a conversation by default for supported models. (#56163) - Enabled memory v2 by default for fresh profiles and added support for importing external-agent memories into it. (#56211, #56414) ## Bug Fixes - Fixed fresh TUI sessions to honor the server’s default approval reviewer when no explicit override is provided. (#56090) - Kept T"

## 2. Quota & Workflow Impact Analysis

High Efficiency — Prefer the newly shipped model tier for daily coding to maximize effective quota per reset window.

## 3. How to Apply in Your Codex Workflow

```
# 1. Update Codex CLI & check live reset window before heavy runs
npx tibosay

# 2. Verify your local environment & AGENTS.md contract
codex --version
```

- When Oracle ≥ 75% : Stress-test this capability on large multi-file tasks before the next global reset overwrites unused regular quota.

- When Oracle < 35% : Pair with targeted single-file verification in AGENTS.md to keep per-turn token usage lean.

> **Key Takeaway (TL;DR)**: ## New Features - Added a built-in Google Cloud Vertex AI provider, configured with `model_provider = "gcp"`. (#56265) - Added GPT-6.1 Terra to the model catalogs. (#57337) - Adde — High Efficiency — Prefer the newly shipped model tier for daily coding to maximize effective quota per reset window.
