Pi Mono: Provider Quirks and Performance Cleanup

Today's activity centers on hardening the AI provider layer against inconsistent vendor behavior, plus a major rendering performance fix in the terminal UI.

Good morning. It's August 9th, and here's what moved in Pi Mono.

The clearest pattern today: the AI layer is absorbing a lot of provider-specific quirks, and each one is a reminder that "OpenAI-compatible" doesn't mean identical. David Brailovsky's fix in commit c185d41 makes sure DeepSeek gets the right max-tokens field, auto-detecting it in both built-in and custom model…

Second theme: terminal UI performance. Mario's commit 18dee5f stops the alt-screen painter from re-compositing every row on every frame, even when nothing changed. That's a 9 to 18x cut in per-frame allocation churn, and it eliminates a real memory penalty—previously 11 to 29 megabytes extra just for running…

On the pi repo side, a batch of smaller reliability fixes: PR 7844 stops Copilot login from enabling every model at once, which was tripping GitHub's rate limit and breaking login outright. PR 7833 swaps a notification hook from "agent end" to "agent settled," so ready-for-input alerts fire only when Pi is actually…

Also worth flagging: PR 7823 is a large, multi-feature import from oh-my-pi—stream rules, subagent tools, and cross-session memory. That's a broad surface area and likely needs careful review…
