OpenAI released GPT Image 2.6. CLIProxyAPI 8.0.56 advertises gpt-image-2.6-sunburst, gpt-image-2.6-flare, and the subscription-only gpt-image-2.6.

• Register the three models. Sunburst and Flare use the 2.5 list prices and accept xhigh and max quality. The api/ route for plain gpt-image-2.6 stays disabled because OpenAI's API has no such model.
• Make gpt-image-2.6-sunburst the automatic image default for OpenAI and GPT chats.
• Add complexity, GIF output with frame_count and frame_duration_ms, and SVG output for 2.6 Sunburst and Flare. GIF and SVG work only for generation and are saved without inline previews. SVG authoring tokens count toward usage.
• Accept only SVG built from static drawing elements, presentation attributes, and same-file references, which matches OpenAI's documented output. Scripts, CSS, comments, animation, event handlers, external references, and non-UTF-8 declarations fail before saving.
• Add markup edits for 2.5 and 2.6 Sunburst and Flare.
• Require PNG or WebP for transparent backgrounds, decode the format a native payload hook requests, and compare image signatures byte for byte.
• Update Biome to 2.6.5 and pnpm/action-setup to 6.1.1.

Confidence Score: 5/5

The PR appears safe to merge, with the existing non-blocking SVG issue still open.

Fix with agent prompt

### Issue 1
src/media.ts:undefined-767
`outputType` checks SVG tag names but not whether their opening and closing tags match. For example, `<svg><g></svg>` passes every check and gets saved as a successful result, although an SVG viewer cannot open it.

As a non-blocking improvement, parse the document with external resources disabled before applying the allowed-element and attribute rules. Add tests for mismatched tags and multiple roots.

Summary

Adds GPT Image 2.6 models and makes Sunburst the automatic image default for OpenAI/GPT chats.

• OpenAI chats can choose GPT Image 2.6 models by default.
• GPT Image 2.6 can save animated GIFs and SVG drawings.
• Sunburst and Flare edits can use a PNG markup layer.
• Build and release tools use the newer package versions.

Summary

Summary by CodeRabbit

• New Features
  • Added GPT Image 2.6 Flare, Sunburst, and base model options, with controls for quality, complexity, markup editing, and GIF frame limits where supported.
  • Image generation now supports GIF and SVG output, with format-specific validation and saved results.
  • The automatic image model now defaults to GPT Image 2.6 Sunburst.
• Changes
  • Bare API-key routes for GPT Image 2.5 and 2.6 are no longer available; use the Flare or Sunburst variants instead.

The catalog adds GPT Image 2.6 variants and updates the default image model. Media requests add markup editing and GIF/SVG output with format-specific validation and usage reporting. Package, Biome, and workflow versions also change.

Changes: GPT Image catalog and media support

Layer / File(s)	Summary
Catalog entries and model controls src/catalog.ts, src/media-defaults.ts, src/media.ts, test/auth-routes.test.ts, test/media.test.ts, test/picker.test.ts, test/provider.test.ts	The catalog adds GPT Image 2.6 variants and controls, and the default changes to gpt-image-2.6-sunburst. Tests cover catalog entries, controls, picker defaults, and route restrictions.
Request validation and markup editing src/media.ts, test/media.test.ts	Image requests validate complexity, output formats, GIF frame settings, and editing constraints. Supported models accept PNG markup layers, which are validated and sent separately from masks.
Format parsing, usage, and results src/media.ts, test/media.test.ts, test/provider.test.ts	GIF and SVG outputs use format-specific validation. Valid SVG authoring usage contributes tokens and cost. GIF and SVG results omit inline previews. Tests cover output handling and payload-hook GIF selection.

Package and workflow updates

Layer / File(s)	Summary
Package and workflow versions .github/workflows/ci.yml, .github/workflows/release.yml, biome.json, package.json	The pnpm action revisions and Biome schema and development dependency are updated. The package version changes to 0.3.5.

Merge Risk: Low · previous review 6d5de

Automatic image requests fail on older proxies that do not advertise the new default. Document the proxy requirement and available model-selection workaround; the remaining risk is bounded.
