v4.399.1 ships three big things: a new Feed (Beta) inbox, a sidebar header rebuilt into a 4-product switcher, and six new AI models in the picker. Chapter summarization gets a matching speed-and-quality bump.

Watch Faster

Six New AI Models — Speed Is the Real Scarcity

The bottleneck isn’t model availability anymore; it’s the speed at which you can chew through every video you wanted to watch. This issue shipped six new models from major providers:

Gemini 3.1 Flash Lite GA
Grok 4.3 + Mistral Medium 3.5
Bailian additions: MiniMax M2.x, Kimi K2.6, Qwen3.6-Max-Preview, Qwen3.6-Flash

Chapter summarization gets a speed-and-quality upgrade alongside — faster output, more reliable on long videos. Open any task on bibigpt.co and you’ll see them in the model picker.

Find What Matters

Feed (Beta) — What Did the Channels You Follow Actually Post?

You subscribe to dozens of YouTube channels and Bilibili UP creators, but the “Subscriptions” menu only shows a long list of channel names — to see what’s new, you’d have to click into each one. That’s a years-old pain point.

The new Feed (Beta) menu fixes it:

Sidebar Feed (Beta) menu — all subscribed channels' latest videos, sorted by publish time

It aggregates every subscribed channel’s latest videos into a time-sorted inbox, with Unread / All / Read filter tabs alongside “Subscribed Channels”, “Refresh”, and “Mark All as Read” — operating like a proper RSS reader. Source filtering supports per-platform chips:

Filter the feed by platform (YouTube, Bilibili, etc.)

“Subscriptions” and “Feed” aren’t duplicate features — they’re the two ends of the RSS mental model: Subscriptions = who I follow, Feed = what they posted. Paired with BibiGPT’s auto-summary, your subscription list becomes “an AI-augmented RSS reader that summarizes everything and pushes it on a timeline”. Entry: bibigpt.co → left sidebar → Explore → Feed (Beta).

Private channels that require login (YouTube private, Bilibili members) get their own authorization prompt — subscriptions reach further than before.

Batch Move / Copy for Collections — One Click, Many Videos

The Collections page gets a batch operations panel — select multiple videos, then move or copy them to another collection in one click. For anyone building a learning library or knowledge base, this should’ve shipped long ago.

Usage Stats — New Dimensions This Issue

bibigpt.co/user/usage gains three new dimensions to quickly answer “where did my time actually go this week”:

Total duration for the current period
Top-duration video ranking — which 1h+ videos consumed the most attention
Breakdown by usage channel (API / Web / Desktop / WeChat / Mini Program) — which entry point you actually use

Language learners, researchers, and podcast listeners are most likely to discover “wait, I listened to 8 hours of podcasts this week?” here.

Make More With It

Sidebar Product Switcher — BibiGPT Is More Than “Video Summary”

The sidebar header expanded from a single “New Summary” entry into four product entries: New Summary, AI Chat, AI Tasks, AI Edit. One click jumps straight into the matching product’s workspace — the BibiGPT product family swappable from one sidebar:

Sidebar top 4-icon switcher: New Summary / AI Chat / AI Tasks / AI Edit

Each icon goes to the real workspace, not a marketing page. AI Chat drops you straight into the chat workspace:

Click AI Chat icon to land directly in the chat workspace

AI Edit drops you straight into the edit workspace:

AI Tasks drops you straight into the tasks workspace:

Desktop Folder Watcher — Reimagined

Folder watcher is one of the most-used desktop features, and this issue pushes the experience to a new bar:

Pre-select a target collection before starting — every new video lands in the right bucket automatically
Concurrency control: default 3 lanes, configurable — drop as many videos as you want, they queue up cleanly
Task resumption: auto-continues where you left off on startup
Close-window guard: confirms before quitting with active tasks

The whole thing runs smoother and more reliably — the most upgrade-worthy desktop change this issue.

Desktop: Record System Audio + Microphone Together

Mac records system audio + microphone simultaneously: in meetings, podcasts, and tutorial demos, the sound from your computer and what you say can be recorded together — no virtual sound card needed.

The desktop client also picked up auto-update — silently downloads new versions in the background without bothering you; a switch in settings can turn it off.

Closing Note

The two things most worth a click this issue are Feed (Beta) and the sidebar 4-product switcher — the first answers “what did the channels I follow just post?”, and the second lets you swap across the BibiGPT product family from one place.
