Prompt Optimizer v2.9.4

Summary

Restored image-to-image upload session persistence so uploaded reference images survive workspace reloads and restores.
Aligned Seedream image-model metadata with the current documented capabilities, including Seedream 4.5 multi-image support and a dedicated built-in Seedream 5.0 Lite configuration.
Added OpenAI Responses request-style support and smoother local desktop routing for self-hosted or LAN LLM endpoints.
Reduced release friction by allowing Run All variants to execute in parallel and by uploading desktop artifacts directly to GitHub Releases.

Highlights

This patch release focuses on practical workflow reliability: image sessions recover correctly, Seedream options match what the provider actually supports, and desktop/local deployments hit fewer routing and release-pipeline surprises.

Product Updates

Desktop

Added a proxy-dispatch path that bypasses the desktop proxy layer for local or LAN-hosted LLM endpoints when direct access is the safer route.
Simplified the desktop release workflow so build artifacts upload directly into GitHub Releases instead of relying on the previous artifact handoff path.

Web

Restored image-to-image workspace persistence so uploaded source images remain available after session restore.
Updated Run All flows to allow variant execution in parallel, reducing unnecessary serialization in the testing UI.

Extension

No extension-specific user-facing features landed in this patch release.

Core/Infra

Added OpenAI Responses request-style support across model configuration and adapter layers.
Updated Seedream model metadata and defaults so Seedream 4.5 advertises multi-image support, uses the current size schema, and Seedream 5.0 Lite exposes its own built-in configuration and parameter surface.

Fixes

Fixed image-to-image session restore losing uploaded image references.
Fixed Seedream built-in defaults and adapter metadata drifting away from the provider’s current documented behavior.
Fixed local desktop model requests being routed through the proxy when they should go directly to local/LAN endpoints.
Fixed release automation so desktop artifacts attach directly to the GitHub Release payload.

Breaking Changes / Upgrade Notes

No breaking API or storage-format changes are introduced in this release.
If you rely on older assumptions about Seedream model capabilities or size presets, review your saved model configurations after upgrading.

Developer Notes

The Seedream update is now driven by model-specific specs instead of a single legacy branch, which should make future provider capability updates safer to maintain.
OpenAI Responses support touches adapter, conversion, defaults, and UI model-management paths, so downstream forks with custom OpenAI-compatible behavior should review their request-style assumptions.
