Source Summary

AI Gateway now exposes **openai/gpt-image-2.5-flare** and **openai/gpt-image-2.5-sunburst**. Both generate and edit images, accept references, support detailed layouts and transparent backgrounds, and can preserve surrounding elements during targeted edits.

Practical Implication

Use **Flare for faster iteration** and switch to **Sunburst for tighter control** over composition and detail. The same gateway also offers usage and cost tracking, retries, failover, budgets, and routing rules.

AI Gateway now exposes **openai/gpt-image-2.5-flare** and **openai/gpt-image-2.5-sunburst**. Both generate and edit images, accept references, support detailed layouts and transparent backgrounds, and can preserve surrounding elements during targeted edits.

Use **Flare for faster iteration** and switch to **Sunburst for tighter control** over composition and detail. The same gateway also offers usage and cost tracking, retries, failover, budgets, and routing rules.

Sunburst takes longer to generate, while the material provides no latency, quality, or cost comparison between the models. Provider pricing is passed through without inference markup or a platform fee, including BYOK requests.

Connected Context · Feed7 Judgment

This adds an explicit two-stage image workflow inside one model family: use Flare for iteration and Sunburst when composition or detail needs tighter control. It reinforces the Gateway as a routing layer for interchangeable generation and editing, but does not displace Seedream, Muse, or Grok because the supplied material contains no cross-model evidence on quality, latency, or cost.

Seedream 5.0 Pro is now available on AI GatewaySeedream remains a relevant alternative for text-heavy and dense-layout work, while Flare and Sunburst introduce a speed-versus-control choice without supplying evidence that either is better for those workloads.Muse Image now available on AI GatewayBoth support generation, editing, and reference-guided iteration through the Gateway; the new pair adds an explicit fast-iteration versus tighter-control split that Muse’s supplied record does not describe.Grok Imagine Image 2.0 now available on Vercel AI GatewayGrok and the new models both emphasize targeted edits that preserve surrounding details, but only Grok’s supplied record adds batching and explicit resolution tiers, leaving application requirements—not availability alone—to determine routing.
