Changes in 1.3.26-beta.4

• Usage card The activity pane shows Claude and Codex separately: the connection, the path a new session takes and the quota, updated right after you save a key or change the run mode.
• Billing check The connection test confirms Claude Code reports an API key as its billing source; if not, new sessions move to the terminal and say why, instead of failing.
• Native path fixes Fixed Codex's native connection and a startup failure when Claude runs through the API.
• Native view Claude (through the API) and Codex (through app-server) run in the app's own view, with commands, changes, plans and confirmations shown directly; Settings can switch back to the terminal view.
• Run mode Settings stores the API key, tests the connection and sets a monthly budget; Claude uses the API by default and moves to the terminal on your subscription when the quota runs out, continuing the same conversation.
• Connection and quota The activity pane shows whether Claude and Codex are connected through the API or a subscription, plus today's and this month's estimated API spend, the budget and rate limits.
• Direct interventions A note to a sub-agent goes straight to it (Claude takes it mid-run, Codex after the current step), not through the main session, and its split shows the delivery state.
• Real-time state The terminal's state reaches the reading view and the activity pane at once, so you can continue the moment it finishes; while a terminal confirmation is open, your message waits and goes out afterwards.
• Update channel Settings › About lets you choose the stable or beta channel; beta needs the beta agreement first, and you can switch back to stable at any time without a downgrade.
• Confirm in terminal In the terminal view, whenever you need to confirm or choose, and whenever you type a slash command, the terminal pops up at once; a terminal that pops up while you type never takes the focus.
• Dashboard Colour charts now compare each model’s time, cost and pass rate at a glance, refreshed every minute.
• Sub-agent split Click a sub-agent in the activity pane and what it is doing shows beside the conversation, one at a time: clicking another replaces it. A dispatched worker takes your note there directly.
• Quote a message In the reading view you can quote a message and continue the conversation from it.
• Built-in skills The built-in version always applies: a project copy with the same name is moved to a recovery folder automatically; to extend one, name your skill “-”.
• Skills update live After a skill changes, a running Claude Code session receives the new version at its next compact or clear.
• Virtual Lab Choose any of the three task sources (this project's history, well-known open-source projects and the AA benchmark); each runs on its own and the results are compared side by side. Models in an experiment cannot reach Docker on your computer or change how they are graded.
• Type while it works Keep typing and sending while Claude Code or Codex works; the message waits until the current step is done. Stop and Esc work at any time.
• Light terminals In the light theme, text drawn for a dark terminal turns dark, so body and secondary text are both easy to read.
• Model routing Back-end design and debugging go mainly to GPT-6.1-Sol, which now defaults to high + fast.
