GPT-Image 2 Prompts Reverse-Engineered: 538 Cases and 21 Industrial Templates Open-Sourced (20.2k Stars)

#5 on GitHub's weekly trending (+5,329 stars): freestylefly/awesome-gpt-image-2 reverse-engineers scattered community GPT-Image 2 cases into structured prompt assets - 538 cases across 13 categories (UI 73, posters 88, photography 78, illustration 58, infographics 52, e-commerce 41), distilled into 21 industrial templates, each with fill-in-blank, JSON, and pitfall guides. The core thesis is Prompt as Code: compress prose prompts into atomic structures of subject/lighting/materials/layout/text-lock, built for agent and automation reuse. It also ships as an npm Agent Skill (gpt-image-2-style-library) installable into Claude Code and Codex with one command. API snapshot 2026-08-26: 20,193 stars / 2,033 forks, MIT, created 4 days after GPT-Image 2 launched, updated daily for four months.

<!-- awesome-gpt-image-2-resource | open-source | GPT-Image 2 Prompts Reverse-Engineered: 538 Cases and 21 Industrial Templates Open-Sourced (20.2k Stars) -->

Now that GPT-Image 2 has pushed AI image generation to "99% accurate text rendering, native reasoning, native 4K," the bottleneck has shifted: the model is not the limit - your prompt is. One GitHub repository takes this to its logical extreme: freestylefly/awesome-gpt-image-2 reverse-engineers 538 community GPT-Image 2 cases into structured prompt assets, then distills them into 21 industrial templates. This week it hit #5 on GitHub's weekly trending chart, gaining 5,329 stars.

GitHub API snapshot (2026-08-26): 20,193 stars / 2,033 forks, MIT license, JavaScript, created 2026-04-25 (four days after GPT-Image 2 shipped), latest commit today (cases 533-538 added - four months of continuous updates). The companion gallery site gpt-image2.canghe.ai works like a product: full-size previews, filter by style or scenario, copy the complete prompt, and test generation after Google sign-in.

Scope note: stars and repo state are API snapshots (2026-08-26); this teardown is based on the repo README, template docs, and the gallery site - a representative review, not a commercial partnership; case quality depends on the paid GPT-Image 2 API.

1. What It Solves: From "Gacha Praying" to "Structured Assets"

The repository's core thesis is Prompt as Code: compress prose-style prompts into structured protocols. The project's diagnosis is sharp - after GPT-Image 2 went mainstream, the competition moved from "can it generate an image" to "can it generate stable, controllable, reusable images." Loose inspirational prompts are worthless in batch generation, template systems, and production workflows; structure is what carries reuse.

The design lands in three atomic moves: split subject, lighting, materials, layout, and visual details into composable parts; make templates natively callable by agents, scripts, and automation systems; and give layout, copy, and information hierarchy structured control. In one sentence: others collect "pretty images"; this repo collects "the programs that can re-produce pretty images."

2. How 538 Cases Are Organized: An Industry Map in 13 Categories

The case library splits into 13 categories covering the mainstream commercial scenarios: UI & interfaces 73 cases, posters & typography 88, photography & realism 78, illustration & art 58, charts & infographics 52, products & e-commerce 41, characters & people 31, brand & logos 27, scenes & storytelling 21, historical Chinese themes 16, architecture & spaces 12, documents & publishing 10, others 28.

The distribution itself is a demand heatmap: UI screenshots, posters, infographics, and e-commerce assets top the list - exactly the capabilities that GPT-Image 2's 99% text rendering newly unlocked (before, AI-generated buttons were all glyph soup, making UI work unusable). Each category ships with cover images and case entries; the gallery site supports one-click copying of the full prompt after browsing by category.

3. The 21 Industrial Templates: Fill in the Blanks, Each With a Pitfall Guide

More valuable than the case library is the template layer. The author calls themselves a "merciless reverse-engineering machine," having distilled 21 templates across 13 categories from hundreds of cases, each with an anti-pitfall guide. The UI category's standard template looks like this:

text
Generate a [platform: iOS/Android/Web] interface screenshot for [product type].
Core features: [Feature A], [Feature B], [Feature C].
Visual style: [minimal/tech/skeuomorphic], primary [color], accent [color].
Layout: [top nav / two-column / card feed], clear hierarchy, generous whitespace.
Output: high-fidelity UI screenshot, readable text, aspect ratio [9:16/16:9].

Fill in the blanks and generate. For agents there is an advanced JSON template: type/platform/layout/style/content/constraints fully structured - the model reads fields, the program assembles templates by field. Specialized templates go further: social screenshot generation (explicitly encoding platform signatures - X's verified checkmark, Douyin's spinning disc, Xiaohongshu's two-column waterfall), and live-stream UI (the layout differences between commerce and talent streams are written into the templates). Each template set ends with a pitfall guide, e.g. "force text locking: require 'text must be absolutely readable and display the specified Chinese exactly' to avoid garbled buttons and placeholder gibberish."

4. The Agent Skill: The Entire Style Library Inside Your Coding Assistant

The step that exceeds every "awesome list" expectation: the same data is packaged as an installable Agent Skill - the npm package gpt-image-2-style-library - installable into Claude Code, Codex, and other local agents with one command:

bash
npx skills add freestylefly/awesome-gpt-image-2 --skill gpt-image-2-style-library --agent claude-code codex --global --yes --copy

Claude Code users can also go through the plugin marketplace: /plugin marketplace add freestylefly/awesome-gpt-image-2, then /plugin install gpt-image-2-style-library@awesome-gpt-image-2. The skill lands in ~/.claude/skills, ~/.codex/skills, and similar folders, effective after restarting the session - tell Claude Code "generate a UI image for this landing page" and the agent automatically references the style library's template structure instead of improvising mystical prose.

5. Who It Is For, and Two Caveats

Who benefits: e-commerce and growth teams producing commercial images at scale (the 41 e-commerce plus 88 poster cases map directly), developers building agent image-generation workflows (JSON templates plus the skill are ready-made), and anyone wanting to systematically learn GPT-Image 2 prompt structure (538 cases are the best textbook).

Two caveats. First, the template system is tuned around GPT-Image 2's specifics (text locking, layout instruction-following) - it ports to other image models but with degraded results. Second, running the cases requires GPT-Image 2's API or a paid ChatGPT tier; for output costs see this batch's reasoning image model comparison (officially $0.006-0.211 per image) and the commercial image SOP. The author is the China-based "Canghe"; the repo ships trilingual READMEs (EN/zh/JA) and a WeChat community.

One-sentence closer: when 538 cases get decomposed into atomic parts and recomposed into 21 templates, prompts finally take the shape of a "library" - image generation has officially left the gacha era and entered the engineering era.

ComfyUI: Why Pros Don't Use Web Image Generators

ComfyUI is the most-starred open-source AI image-generation project on GitHub (122k stars, GPL-3.0), turning diffusion-model generation into a visual node graph. Pros choose it for four reasons: control (ControlNet/LoRA/IPAdapter wireable together), reproducibility (workflows are JSON, re-runnable identically), free/local execution (data stays on your machine), and a custom-node ecosystem. Steep curve, GPU-hungry, GPL-3.0 copyleft - suited for artists and devs who need fine control and a reproducible backend.

DeepInfer Open-Sourced: 155T Tokens/Day, Engine or Factory?

On October 20, 2026 DeepSeek announced full open sourcing of DeepInfer, its production-grade inference framework - the first time the official production engine is available instead of open-source parts plus guesswork. The repository deepseek-ai/DeepInfer ships under Apache-2.0 and measured 17,902 stars, 1,836 forks, and 188 open issues on launch day, while the companion token codec deepseek-recipe is MIT-licensed; the two repositories carry different licenses. Every performance figure below is vendor-reported and has no third-party reproduction yet: a single cluster serves 155 trillion tokens per day (about 38 dollars per card per hour at off-peak pricing), first-token latency of 400 milliseconds, 230 tokens per second generation, 96 percent prefix-cache hit rate, and Prefill throughput per card rising from 60,000 to 1.5 million tokens per second when caching counts. SWA Bounded Replay pins the recompute of cache misses to the last 128 tokens, which nearly halves total Prefill compute and makes cost independent of context length; DSpark speculative decoding drafts up to 5 tokens, adds another 6 percent to live throughput, and yields 14K tokens per card per second; MoE expert replicas reshuffle every 10,000 steps so the busiest card runs only 9 percent above average load. Hardware covers both NVIDIA SM100 and Huawei Ascend 950 NPUs, and setup means a Python 3.12 virtual environment, the DEEPINFER_ACCELERATOR variable, and a source build that pulls DeepSeek-V4.1-Flash-1017 weights by default. The boundaries matter: DeepSeek states that Prefill and Decode disaggregation, data-parallel load balancing, and the KVCache management layer are still not fully open because they couple too deeply to internal infrastructure - this is the engine, not the whole factory - and no official benchmark against vLLM, SGLang, or TensorRT-LLM exists. In production, 8-card servers handle Prefill while 64 to 128-card supernodes handle Decode, with KVCache kept beyond 72 hours to avoid recomputation.

AI Memory Framework, Open-Sourced: Tencent's 3B Tops Opus 5

Tencent Hunyuan open-sourced all three layers of Hy Memory 2.0 on 2026-10-16: the model layer Hy-Memory-30B-A3B (30B total parameters with about 3B active per token, a sparse MoE on HuggingFace at tencent/Hy-Memory-30B-A3B, arXiv 2610.22196), the SDK layer hy-memory (2.0.3 on PyPI at writing time) and the tool layer MemHub (CLI v1.0.3, bootstrapped via the npm memhub-cli package). License check: the GitHub API reports NOASSERTION (non-standard text), but the raw LICENSE file is Apache-2.0 with a Tencent preamble and no added restrictions - this article follows the LICENSE text. Official documents mix two spellings, "Hy-Memory-30A3B" and "Hy-Memory-30B-A3B"; we follow the HF repository name. Official benchmarks (vendor-reported): first place at 55.49 in a four-way memory-system comparison, ahead of Opus 5 (54.62) and DeepSeek-Flash (53.64), while Qwen3-30B-A3B scores only 44.37; MemoryArena 55.31 percent, leading runner-up EverOS by 10.2 points; CodeMemoryBench 64.2/35.6; SWE-ContextBench 28.3; LoCoMo 72.6 percent with memory tokens cut from 1159 to 703 (-39.3 percent). Internal business validation (vendor-reported): stock-picking multi-hop recall up from 50 to 90 percent, iWiki up 48.6 percent relative. Positioning is a memory-writer workhorse (analyst take, secondary): the model specializes in writing and updating memory and can in principle sit under existing systems like Mem0 or MemOS. MemHub tool count in two versions: the README lists 5 while the official WeChat article says 10 - go by actual CLI output. Five limitations stated as-is: vendor-only benchmarks without third-party replication, preview-stage API churn, MemHub limited to Linux/macOS, a 30B-class model that is nontrivial to self-host, and thin English docs. Repository: github.com/Tencent-Hunyuan/Hy-Memory (verified reachable). Division note: ai-agent-long-term-memory-sop (2026-08-08) covers the build-your-own mem0/Letta route; this piece covers Tencent's ready-made stack.
