AI Daily Brief — 2 April 2026

Two heavyweight launches on the same day: Cursor 3 ships its rebuilt, agent-first IDE with an Agents Window and up to eight parallel agents, while Google releases Gemma 4 — four open multimodal variants (2.3B → 31B), with the 31B Dense climbing to #3 globally on Arena AI among open models.

Top stories

• Cursor 3 launches. The biggest interface overhaul since 2023: an Agents Window replaces the Composer pane, parallel execution lets you run up to eight agents simultaneously across Git worktrees, multi-repo workspaces, cloud-agent handoff, and a built-in Design Mode. The release runs on Composer 2 — Cursor’s own coding model, with ~75% of total compute spent on continued pre-training and large-scale RL on top of Kimi K2.5 from Moonshot AI. via Cursor
• Google releases Gemma 4. Four open variants from 2.3B to 31B parameters, natively multimodal (text + image + video; audio in selected variants), under Apache 2.0. The 31B Dense ranks #3 globally on Arena AI among open models. The headline benchmark jump: Codeforces ELO 110 → 2150, a 20× improvement over Gemma 3 in competitive coding. via Google
• VentureBeat — Cursor’s Chinese base-model exposure. Reporting highlights that Composer 2’s base is Kimi K2.5 — open-source from Moonshot AI, a Chinese startup backed by Alibaba, Tencent and HongShan — and frames the dependence as a structural problem for Western “open” AI. via VentureBeat

Who shipped

Cursor shipped Cursor 3 and detailed the Composer 2 stack. Google dropped the Gemma 4 family (2.3B / 7B / 14B / 31B) and bundled it for Apache 2.0 use.

By the numbers

• 8 parallel agents in Cursor 3 via Git worktrees
• 20× jump in Gemma’s Codeforces ELO (110 → 2150) from v3 to v4
• Gemma 4 31B Dense — #3 globally on Arena AI among open models
• ~75% of Composer 2’s training compute went into Cursor’s continued pre-training + RL on top of Kimi K2.5
