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 Pieces for Developers?

Pieces is building an ambient developer memory layer, adding audio capture and scheduled summaries on top of its rebuilt local LLM engine.

Pieces operates as an AI-powered context manager for developers, centered on its Long-Term Memory (LTM) system that accumulates context across coding sessions. Version 5.1.0 ships a rebuilt local LLM engine alongside Scheduled Summaries, resolving performance bottlenecks that were limiting the product's ambient capabilities. Audio capture for LTM, launched in February 2026, makes the product a passive workstream recorder—developers no longer need to manually tag or save context.

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.

P0.0

Pieces is building an ambient developer memory layer, adding audio capture and scheduled summaries on top of its rebuilt local LLM engine.

◆ Current state

Pieces operates as an AI-powered context manager for developers, centered on its Long-Term Memory (LTM) system that accumulates context across coding sessions. Version 5.1.0 ships a rebuilt local LLM engine alongside Scheduled Summaries, resolving performance bottlenecks that were limiting the product's ambient capabilities. Audio capture for LTM, launched in February 2026, makes the product a passive workstream recorder—developers no longer need to manually tag or save context.

◆ Where it's heading

Pieces is converging on continuous ambient capture: it now ingests audio, screen, and code context automatically, then surfaces it through scheduled digests and single-click summaries. The rebuilt local engine suggests the team treated cloud dependency as a risk and is pushing toward a fully on-device architecture. MCP integration (April 2025) shows a parallel push to export this memory layer as infrastructure other AI tools can query.

◆ Prediction

The next logical move is team-level memory—aggregating LTM across multiple developers in a shared workspace. The Flat Capital investment gives runway to build this; the Nano-Models architecture makes it feasible at low inference cost.
