feat(image-generator): add gpt-image-2 model support

[waleedlatif1]

Summary

• Add gpt-image-2 as a model option in the Image Generator block
• Wire up gpt-image-2 specific params: size (auto, 1024², 1536×1024, 1024×1536, 2048², 3840×2160), quality (auto/low/medium/high), background (auto/opaque — transparent not supported per docs), output_format (png/jpeg/webp), moderation (auto/low)
• Share quality/background/output_format wiring with gpt-image-1; moderation is gpt-image-2 only
• Verified parameter values against OpenAI's official gpt-image-2 docs

PR Summary

Medium Risk
Moderate risk because it expands the image generation parameter surface and request shaping for a new OpenAI model, and flips a block’s authType from none to api-key, which could affect access/config in production.

Overview
Adds gpt-image-2 support to the Image Generator block and openai_image tool, including new UI options and request params (quality, background, outputFormat, moderation) plus model-specific validation/defaulting for size and other fields.

Updates docs and integration metadata to reflect the new image model capabilities, refreshes Knowledge tool docs with new reranker inputs, updates Mem0 docs to match new async/paginated response fields, and adds a new table trigger docs page and entry in triggers meta.json. Also changes one integration’s authType in integrations.json from none to api-key.

Greptile Summary

Adds gpt-image-2 as a third model option in the Image Generator block, wiring up its dedicated size options (up to 3840×2160), quality levels, background (opaque/auto only), output format, and moderation parameters. The implementation correctly validates size, quality, and background via ALLOWED_* allowlists in the block params function, maps camelCase outputFormat → snake_case output_format in the tool, and shares the quality/outputFormat/moderation path with gpt-image-1. The PR also includes several unrelated documentation changes (knowledge, mem0, table trigger docs) and a authType: "none" → "api-key" fix for the knowledge integration entry in integrations.json.

Confidence Score: 5/5

Safe to merge — no P0 or P1 issues found in the feature implementation.

The core feature code is correct: new params are validated against allowlists, the camelCase → snake_case mapping is handled in the right layer, the response handler already supports b64_json for gpt-image-2, and dall-e-3 is not affected. The one open comment is a P2 documentation nit on an unrelated table trigger doc file.

No files require special attention; the documentation in apps/docs/content/docs/en/triggers/table.mdx has a minor duplicate description worth cleaning up.

Important Files Changed

Filename	Overview
apps/sim/blocks/blocks/image_generator.ts	Added gpt-image-2 model with dedicated size/quality/background/outputFormat/moderation dropdowns; validation via ALLOWED_* allowlists for size, quality, and background; outputFormat and moderation are passed through without server-side validation (consistent with pre-existing background handling).
apps/sim/tools/openai/image.ts	Extended request builder to forward quality, outputFormat (→ output_format), and moderation for gpt-image-1 and gpt-image-2; updated size default fallback; improved log message to interpolate model name.
apps/sim/app/(landing)/integrations/data/integrations.json	Two changes: image-generator longDescription updated to mention GPT Image 2; knowledge block authType changed from "none" to "api-key" (likely coincidental, correct given the Cohere API key now documented for the knowledge block).
apps/docs/content/docs/en/triggers/table.mdx	New trigger documentation; tableSelector and manualTableId share the identical description "The table to monitor." and are both marked Required, which is misleading.
apps/docs/content/docs/en/tools/image_generator.mdx	Updated parameter table to document gpt-image-2 size options, quality levels, background, outputFormat, and moderation; correctly reflects the block implementation.
