During October 2025, Toms Seisums developed end-to-end support for aspect ratio configuration in Gemini image generation within the vercel/ai repository. He implemented this feature by extending Google Generative AI Options, allowing users to specify image aspect ratios during generation, which addressed a key user need for controlled image framing. Toms used TypeScript and applied full stack development skills, covering code changes, comprehensive tests, and documentation updates. He manually verified the feature in real project scenarios and prepared the release with changesets and formatting improvements. The work demonstrated depth through careful integration, regression safety, and alignment with Gemini 2.5 production readiness.
