WalkthroughChangesxAI image requests now support aspect ratios, JSON image inputs, and multipart uploads. The adapter validates masks, image types, URLs, missing images, and streaming requests. Multipart files become base64 data URLs. Tests cover valid and rejected request forms. xAI image input support
Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🟡 Moderate · up to The PR changes image-edit request conversion to support the upstream JSON format, but the current implementation can reorder multiple images, forward unsupported file types, accept excessive image counts, lose optional-field semantics, and fail lint checks. These bounded issues should be addressed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

golangci-lint noctx analyzer httptest.NewRequest NewRequestWithContext
💡 Result:
The noctx linter in golangci-lint is designed to detect HTTP requests that are made without an associated context.Context [1][2]. When it encounters a call to net/http/httptest.NewRequest, it will trigger a finding because this function does not accept a context [3][4]. To resolve this issue, you should use net/http/httptest.NewRequestWithContext instead [3][5]. This function was introduced to the standard library specifically to allow providing a context.Context when creating requests for testing purposes [6][4]. ### Recommended Action Replace calls to httptest.NewRequest with httptest.NewRequestWithContext [5]. For example, you can pass the context from your test runner (such as t.Context() in modern Go versions) [5]: // Old (causes noctx warning) req:= httptest.NewRequest("GET", "/", nil) // New (passes linter) req:= httptest.NewRequestWithContext(t.Context, "GET", "/", nil) If you have specific files or test suites where you prefer not to use NewRequestWithContext, you can exclude them from the noctx linter in your .golangci.yml configuration: issues: exclude-rules: - path: _test.go linters: - noctx This approach allows you to maintain clean code that adheres to the noctx requirement for context-aware request handling [5].

Sort indexed image fields by numeric index.
sort.Strings places image[10] before image[2]. This changes the client-specified image order.
Parse the bracketed index and sort by its numeric value. Reject malformed indexed field names or place them after valid indexes.

xAI API image edits maximum number of input images multipart image[] grok imagine image edits
💡 Result:
The xAI Imagine API supports image editing through the /v1/images/edits endpoint [1][2][3]. For multi-image editing, you can provide a maximum of three source images in a single request [4][3][5]. Key technical details for image edits include: * Request Format: The API requires application/json format [1][6]. Using multipart/form-data (often used by default in some SDKs) is not supported and will result in a 415 Unsupported Media Type error [1][6]. * Input Options: Source images can be provided as public URLs, base64-encoded data URIs, or file_id references from the xAI Files API [1][4][3]. * Implementation: Developers should use the xAI SDK, Vercel AI SDK, or direct HTTP requests that explicitly send JSON [1]. In your JSON payload, the image parameter (or images array for multi-image edits) is used to pass these references [1][4][3]. * Aspect Ratio: By default, the output aspect ratio is determined by the first input image, though this can be overridden using the aspect_ratio parameter [4]. While some third-party sources may reference older or different constraints, official xAI documentation specifies a limit of three source images for multi-image editing [4][3][7].

xAI API image inputs supported image formats data URL official documentation
💡 Result:
The xAI API supports image inputs for both vision-based understanding tasks and image generation/editing tasks via the Imagine API [1][2][3]. Supported Image Formats According to official documentation, the supported image file types for input are JPG/JPEG and PNG [1]. Data URL and Input Methods The xAI API supports providing images using the following methods [4][5]: - Base64-encoded data URIs (e.g., data:image/jpeg;base64,<base64_image_string>) [1][5]. - Publicly accessible URLs pointing to an image [1][5]. - File IDs from the xAI Files API [4][5]. For vision models (image understanding), images are typically included within the message content payload [1]. For the Imagine API (image editing/generation), images can be provided as part of the request body, often within an image object containing the URL or data URI [2][5]. Additional Specifications - Maximum image size: 20 MiB [1]. - Maximum number of images: No stated limit for vision inputs [1]. - For multi-image editing, you can provide up to three source images in a single request [4]. Note: When using direct HTTP requests, ensure your requests use application/json content types, as the API does not support multipart/form-data for image editing [5].

Use pointer types for the optional scalar fields.
AspectRatio and ResponseFormat are optional fields in an upstream-remarshaled request. Their value types cannot distinguish an absent field from an explicit empty value.
Use *string with omitempty. Set each pointer only when the source field is present.
As per coding guidelines: “Optional scalar fields in client-parsed and upstream-remarshaled request structs must use pointer types with omitempty.”
