ChatGPT Images 2.0 (model name: gpt-image-2) is OpenAI's first image generation model with native reasoning built into the architecture. Released April 21, 2026, it ships to all ChatGPT, Codex, and API users — with a Thinking mode (web search during generation, batch up to 8 images, self-verification) reserved for Plus ($20/mo) and above. The headline improvement is text rendering: gpt-image-2 achieves approximately 99% character accuracy in generated images, compared to the scribbled gibberish that plagued earlier models. This eliminates the biggest practical limitation for designers, marketers, and content creators who need AI images with readable labels, signs, UI mockups, or typographic elements. It also supports non-Latin scripts with improved accuracy. Beyond text, Images 2.0 brings: 2K resolution output, aspect ratios from 3:1 to 1:3, consistent characters and objects across up to 8 images in a single batch, and visual reasoning that lets the model analyze a reference image and incorporate real-time information. For API developers, gpt-image-2 is available now with the same interface as gpt-image-1, making migration trivial. The gap between AI image generation and real production use just got significantly smaller.

FluidCAD is a web-based parametric CAD application that models geometry through JavaScript code instead of mouse-driven GUI operations. Users write code to define extrusions, fillets, boolean operations, and patterns; dragging in the live viewport generates code values that get locked into the script. It supports STEP file import/export with color, a feature history that can be stepped through and rolled back, and VS Code extension support. Gained 149 upvotes on Show HN today, targeting engineers who want code-first CAD with a traditional feature tree.
Reviewer scorecard
“99% text accuracy in generated images is the unlock that finally makes AI image generation production-viable for UI mockups, marketing assets, and anything with labels or copy. The gpt-image-2 API drop-in replacement makes this a zero-friction upgrade. Ship it today.”
“FluidCAD solves the thing OpenSCAD got wrong: the 'drag to prototype, lock to code' loop makes it accessible without sacrificing programmability. STEP export means it fits into actual hardware workflows, not just rendering. For software engineers doing mechanical work, this is the missing middle ground between Fusion 360's complexity and OpenSCAD's austerity.”
“The Thinking mode — the feature that actually makes this interesting for complex, multi-image, web-search-augmented generation — is locked behind Plus or Pro tiers. The 99% text accuracy claim also needs broader real-world validation; complex multi-element compositions still reportedly produce errors.”
“Code-first CAD has a 30-year history of failing to reach mainstream adoption because engineers and designers don't want to write JavaScript. FluidCAD will appeal to a very narrow slice of software developers who also do mechanical work. The STEP import/export is table stakes, not a differentiator, and Onshape's API does everything this does for teams who need collaboration.”
“Native reasoning in image generation is a bigger deal than it sounds. When a model can 'think' about what it's about to draw, verify its output, and search the web for reference context, you're moving from stochastic image generation to visual reasoning. The design tool stack is being rebuilt from scratch.”
“When AI can generate CAD from natural language, the tools that survive will be the ones with programmatic, diffable representations — not binary blob formats. FluidCAD's JavaScript-first approach puts it in exactly the right position for the AI-assisted hardware design wave that's coming. This is the OpenSCAD for the LLM era.”
“Text that actually renders correctly in AI images is genuinely transformative for content creation. Mockups, social graphics, ad creatives with overlaid copy — I've been waiting for this for two years. The 8-image consistent character batch is also a game changer for storyboarding and consistent brand imagery.”
“I appreciate the concept but the UI is clearly built by engineers for engineers. There's no real onboarding, the documentation assumes CAD literacy, and the JavaScript API surface is intimidating for anyone coming from traditional design tools. Until there's a visual-first entry point, this stays a curiosity for most designers.”
