What is InvokeAI?

InvokeAI 7 reaches beta with projects and a single widget workbench as the new default.

InvokeAI 7.0.0 beta 1 shipped on November 9 after four alphas, making the rebuilt interface the default. v7 organizes work into autosaving projects that hold canvas, settings, workflows and boards, and replaces separate tabs with one workbench of movable widgets, including Video. It requires Python 3.12 and a one-way database migration, so v6 users are told to install into a fresh root.

What is vLLM?

vLLM opens its 0.34 cycle by moving more models onto the Transformers backend

vLLM's feed shows release candidates rather than release notes. The 0.33 cycle ran four candidates in late October with ROCm, NVFP4 and test-checkpoint fixes. The 0.34 cycle opened on 8 November by moving Gemma and StableLM onto the Transformers backend; rc1 added a NaN fix for speculative decoding on Intel XPU, and rc2 on 12 November only touches docs and tests.

InvokeAI 7 reaches beta with projects and a single widget workbench as the new default.

◆ Current state

InvokeAI 7.0.0 beta 1 shipped on November 9 after four alphas, making the rebuilt interface the default. v7 organizes work into autosaving projects that hold canvas, settings, workflows and boards, and replaces separate tabs with one workbench of movable widgets, including Video. It requires Python 3.12 and a one-way database migration, so v6 users are told to install into a fresh root.

◆ Where it's heading

The v7 rewrite has moved from tester alphas to a feature-complete beta, and the v6 line is down to small patches. The next stretch is bug fixing and moving v6 users across, with the legacy interface kept only as a fallback.

◆ Prediction

Expect further v7 betas, then a 7.0.0 release, with v6 limited to critical fixes like the 6.14.4 startup patch.

vLLM opens its 0.34 cycle by moving more models onto the Transformers backend

◆ Current state

vLLM's feed shows release candidates rather than release notes. The 0.33 cycle ran four candidates in late October with ROCm, NVFP4 and test-checkpoint fixes. The 0.34 cycle opened on 8 November by moving Gemma and StableLM onto the Transformers backend; rc1 added a NaN fix for speculative decoding on Intel XPU, and rc2 on 12 November only touches docs and tests.

◆ Where it's heading

Cycles are short and the visible work is hardware coverage and consolidation. Moving older model families onto the generic Transformers backend points to less per-model code to maintain as new architectures arrive.

◆ Prediction

Expect one or two more 0.34 candidates before a final release; the feed does not show the cycle's full feature set, so its scope stays unclear.
