What is InvokeAI?

InvokeAI 7 alpha 3 turns boards into shared, role-gated spaces and adds Qwen-Image-2.1.

InvokeAI is a local-first image and video studio three alphas into a v7 rewrite. Alpha 1 replaced the tabbed UI with autosaving projects and a widget workbench; alpha 2 added MySQL/MariaDB backends and per-project boards. Alpha 3 adds board sharing with Viewer, Contributor, Editor and Owner roles, keeps each member's settings separate inside a project, and brings back a long list of legacy features. It also adds Qwen-Image-2.1 and an opt-in SageAttention backend that cuts large NVIDIA generations by 15–35%.

What is Synthesia?

Synthesia is becoming a general AI video editor — avatars are now one feature, not the product.

Synthesia has spent the last six months extending its product surface well beyond AI avatar generation. The Editor now ingests external screen recordings (MP4 → transcribed, scene-split, editable Synthesia video), accepts .pptx with speaker notes as voiceover, and runs an AI Playground that exposes third-party models — Sora 2, Veo 3.1, FLUX.2, Nanobanana Pro — directly inside the canvas. Avatar capability also broadened: action-taking stock avatars with arbitrary backgrounds, speech regeneration, and per-voice speed control. The release cadence has slowed visibly since March, with no public updates in the past two months.

InvokeAI 7 alpha 3 turns boards into shared, role-gated spaces and adds Qwen-Image-2.1.

◆ Current state

InvokeAI is a local-first image and video studio three alphas into a v7 rewrite. Alpha 1 replaced the tabbed UI with autosaving projects and a widget workbench; alpha 2 added MySQL/MariaDB backends and per-project boards. Alpha 3 adds board sharing with Viewer, Contributor, Editor and Owner roles, keeps each member's settings separate inside a project, and brings back a long list of legacy features. It also adds Qwen-Image-2.1 and an opt-in SageAttention backend that cuts large NVIDIA generations by 15–35%.

◆ Where it's heading

Each alpha moves InvokeAI further from a single-user desktop app toward a shared workspace: pluggable databases, then project boards, now per-role permissions and per-member settings that the notes call groundwork for collaboration later in 7.x. Model support keeps pace in parallel, and the priority is running new models on existing hardware through GGUF, fp8 and quantized attention. Restoring legacy features signals the team wants v7 at parity before it asks v6 users to migrate.

◆ Prediction

Expect alpha 4 within about a week, with more parity restoration and collaboration plumbing; project file formats may break again, since alpha 3 already did. The entries still give no beta or stable date.

Synthesia is becoming a general AI video editor — avatars are now one feature, not the product.

◆ Current state

Synthesia has spent the last six months extending its product surface well beyond AI avatar generation. The Editor now ingests external screen recordings (MP4 → transcribed, scene-split, editable Synthesia video), accepts .pptx with speaker notes as voiceover, and runs an AI Playground that exposes third-party models — Sora 2, Veo 3.1, FLUX.2, Nanobanana Pro — directly inside the canvas. Avatar capability also broadened: action-taking stock avatars with arbitrary backgrounds, speech regeneration, and per-voice speed control. The release cadence has slowed visibly since March, with no public updates in the past two months.

◆ Where it's heading

The strategic move is from 'create a video by typing a script for an avatar' to 'turn any input (slides, recordings, prompts) into a Synthesia-editable video,' with third-party genAI models embedded in the canvas. Avatars are repositioning as one input among many, not the headline. The pause in release cadence since March is notable for a product that was shipping every two to three weeks through Q4 2025 — could indicate a larger release in flight, a strategic reorientation, or commercial pressure squeezing the public-facing tempo.

◆ Prediction

The next visible release will likely be the next-generation avatar tier (the action-taking stock avatars were called 'one of the most exciting updates of the year' in November, so an upgrade or open-prompt avatar variant is overdue), or a foundational change to the ingestion pipeline that ties the screen-recording and PowerPoint surfaces into a single 'video from anything' flow. If the silence continues past Q2, that's a signal worth watching.
