Which AI models are included?

40+ open-source models across providers including DeepSeek, Qwen, Mistral, Kimi · Moonshot, MiniMax, GLM · Zhipu, Meta Llama, NousResearch, and more. New SOTA models are added on a rolling basis as they become available.

Diagrams are drawn, drawings show up, and a failed reply says why

Mermaid diagrams are drawn. A diagram artifact used to show its source; it now renders as a picture, in the viewer and in the gallery. One that will not parse shows its source with the reason.
Drawings no longer come up blank. An SVG that only set a viewBox rendered as an empty frame; it now fills it.
A failed reply keeps saying why after you reload, instead of showing an empty message. And when a model simply is not available, you are told so straight away rather than asked to retry.
Install commands keep your key out of the URL. The one-liners on the MCP Store, Koda and editor pages now send your key as a header. Commands you copied before still work.
Settings works on a phone — every section used to be cut off on the right.
Activity charts use your days, not UTC — an evening's work no longer lands on the wrong date.

Fixes & QOL: a deleted artifact's card in a conversation says so instead of opening an empty panel; the resources panel opens on narrow screens; What's New previews cut between lines; toasts no longer cover the Support button; the MCP Store is rebuilt; a missing conversation offers a way back; the Referrals monthly tile says what it counts.
