# OpenAI GPT-5 Startup Hackathon: Project Gallery - **Event:** [OpenAI GPT-5 Startup Hackathon](https://cerebralvalley.ai/e/gpt5) - **When:** Aug 9 at 10:00 AM – Aug 10 at 5:00 PM (PDT) - **Where:** Location TBA - **Hosts:** [Cerebral Valley](https://cerebralvalley.ai/u/cv), [OpenAI](https://cerebralvalley.ai/u/openai) - **Projects:** 92 (6 placed) - **Page:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery ## Projects ### 1. emoCAPTCHA This project is a CAPTCHA-like authentication system where the user is shown an emoji and must mimic the same facial expression in front of their camera to pass the verification. Regular CAPTCHAs are tedious. emoCAPTCHA makes verification playful by asking people to mimic emojis. Beyond fun, the goal is societal benefit: modern AI still struggles with reading human emotions, and ethically sourced examples of real facial expressions can help improve that. If users choose to contribute, their emoji-matching selfies could form a valuable dataset to train models to better understand human emotions. - **Team:** [Kazuki Nakayashiki](https://cerebralvalley.ai/u/kazuki) - **GitHub:** https://github.com/kazuki-sf/emoCAPTCHA - **Demo video:** https://www.youtube.com/watch?v=IYQdEOPbSjE - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=1 ### 2.

Moteo Video composition application using GPT-5 as a backbone to prompt and create motion graphics from code. Users prompt the visuals they want in natural language, retool the result and compose them together into larger projects. Each video can be converted into a "block" which is automatically parameterized and can be added as pieces to other videos, which themselves can be blocked as well. The LLM takes in visuals, textual data, research context as parameters to each video block to create graphics, animations, etc. anchored to data and contextually linked via the LLM. The result is LLM as a context-manager for a graphics studio that can export to apps, chain data, and be automated to generate based on fed parameters which semantically evolve and develop with the content of the video. - **Team:** [Sam Inloes](https://cerebralvalley.ai/u/saminloes), [max apple](https://cerebralvalley.ai/u/mapple) - **GitHub:** https://github.com/Sami1309/snackathon - **Demo video:** https://youtu.be/Md03oqrhJ7E - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=4 ### 5. Ref Ref is an MCP server for providing context to coding agents. For this project I explored adding code base indexing. GPT5 wrote a vectordb, graphdb and text-search index for code that run in a local MCP server. It then wrote a benchmark to evaluate performance and optimized for it. Then, of course, rewrote to Rust. I also explored GPT5's UI generation using Goose + mcp-ui to have GPT5 generate UI on the fly to visualize the codebase. - **Team:** [Matt Dailey](https://cerebralvalley.ai/u/mattdailey) - **GitHub:** https://github.com/ref-tools/ref-tools-mcp/tree/hackathon-aug-9 - **Demo video:** https://www.youtube.com/watch?v=9AJSInXATP8 - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=5 ### 6.

LastApp, Inc. LastApp.ai is AI based true Native Mobile App Builder. But how do we ensure Mobile Apps we built function as expected before users report? As part of Hackathon we solved this problem. We pass our screenflow initial design (Generated from user prompt originally) and ask GPT-5 API to decide each screen and what operation needs to be performed on the screen and decide on success/fail criteria. We then launch the simulator/emulator and perform the operation, then send the after screen back to GPT-5 and its own criteria from earlier and ask whether Screen functionality on app worked as expected. On success, continue to next screen and on failure, use our existing process to fix the app with help from GPT-5 API on failure reason. This is more like CUA in the API that works well with emulators/simulator.   With this GPT-5 agent, after building Native Mobile Apps (Swift/iOS, Kotlin/Android, backend), we can make sure the App is fully functional and automatically fix any issues that are found. - **Team:** [Kumar Mettu](https://cerebralvalley.ai/u/kumarlastapp) - **GitHub:** https://github.com/kumardexati/OpenAIHackathon080925 - **Demo video:** https://www.youtube.com/watch?v=Oa48Qgg4Ov4 - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=7 ### 8.

Throngs Throngs is a god simulation game where AI-driven pixel creatures called "Throngs" come to life through GPT-5's language generation, each developing unique personalities and relationships through dynamic conversations. Players act as a deity in randomly generated isometric worlds, typing divine messages that trigger contextually-aware responses reflecting each Throng's emotional state, devotion level, and relationship history. Beyond conversation, players can nurture their followers by planting food, feeding them directly, or cleaning them with divine powers, while Throngs autonomously bathe in lakes and interact with each other, forming friendships or rivalries based on GPT-5's evaluation of their conversations. Their devotion level fluctuates based on whether their god proves benevolent or cruel in their conversations. - **Team:** [Gui David](https://cerebralvalley.ai/u/gui) - **GitHub:** https://github.com/gdavidss/throngs - **Demo video:** https://www.loom.com/share/014c47ee032b4d6aa677aa74fe2d3b76 - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=32 ### 32. RNA Optimization We wanted to utilized and highlight the expanded GPT5 context window and improved hallucination. Thus for application, we attempted to optimize the RNA sequence for the spike protein (large sequence to utilize the larger context window) for thermal stability to skip the cold-chain transport requirements (we have 3rd party software to visualize the new structure to validate optimization). We were able to improve the temperature by 0.3C, not dramatic, but decent for such a large structure in 24hrs. The new structure (our startup has structure prediction and visualization software for RNA) was able to display the original and improved sequences to show that there are significantly fewer double-stranded RNA, which may decrease innate immune response but boost adaptive immune response which is more targeted and longer lasting. (We used the original spike protein sequence, not modified for efficiency, to ensure that this code doesn't land in the wrong hands). - **Team:** [Gwen C](https://cerebralvalley.ai/u/modelturnedgeek) - **GitHub:** https://github.com/modelturnedgeek/RNAoptimization - **Demo video:** https://www.loom.com/share/6c754e18a4d945b4b568753fcd5cee9d?sid=5843064d-374f-41ea-a4cc-ae1feeb268f9 - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=33 ### 33.

Often, it is difficult to understand how everything will fit together during the call, since the conversation might be long and touch on complicated accounting integrations that we can't model in real-time. In this project, we created an agent that is able to join Google Meet calls, convert the audio into a transcript, and provide meeting notes, domain-specific business insights, and map the client's accounting workflow all in real-time. We were able to accomplish a significant amount of this in the current code, and have plans to expand the agent functionality by integrating more tool use. - **Team:** [Valentin de la Pena](https://cerebralvalley.ai/u/valentin), [Mostafa Al Mohammad](https://cerebralvalley.ai/u/Mostafa) - **GitHub:** https://github.com/uiagent/openai-hackathon - **Demo video:** https://www.loom.com/share/65dbe42de9534a1086cd3615e030db3d?sid=4c6ff73c-b726-4bfb-8fde-636cbeb1ae77 - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=46 ### 46. Argus We’re building a multi-agent admissions and guidance system that transforms how students discover, apply to, and are evaluated for educational programs. Different specialized AI agents — including a guidance agent, interview agent, assessment agent, and application review agent — work together in real time to guide the student, collect materials, conduct interviews, manage adaptive assessments, and evaluate final applications. By compressing program discovery, advising, application, assessment, and decision-making into a single, fluid process, we cut months of friction for students and reduce cost and workload for institutions. The result is faster, more consistent decisions, better student-program matches, and a seamless, personalized admissions experience at scale. - **Team:** [Srishti Lodha](https://cerebralvalley.ai/u/srish), [michael weiler](https://cerebralvalley.ai/u/mweiler) - **GitHub:** https://github.com/edupath/argus_hack - **Demo video:** https://www.loom.com/share/f4a758482e474edebfdfd7c372f17682?sid=ef98e846-b2ee-45e3-b93d-9425a1772a06 - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=47 ### 47.

Pravāh Electric grid operators are overwhelmed with the data needed to manage complex grid operations, including weather, state-space estimation, network congestion, bidirectional electricity flow, DER coordination, and asset failures. We developed an agentic grid orchestration framework that enables operators to utilise GPT-5 with multimodal data inputs within a power-flow solver, incorporating fail-safe contingencies. We built five agents - each with their own objective function, such as asset health monitoring, reliability, safety, power purchase cost reduction, etc., to operate an optimal system under physical constraints. We struggled to fine-tune the agents, so actions defaulted to conservative choices, and we were unable to connect the refined front end to our backend fully. - **Placement:** 2nd Place - **Team:** [Mohak Mangal](https://cerebralvalley.ai/u/mohakmangal), [Dhruv Suri](https://cerebralvalley.ai/u/Dhruvsuri) - **GitHub:** https://github.com/pravah-hq/pravah-open-ai-hackathon - **Demo video:** https://www.loom.com/share/1bcad8e9b8b745749324e9a19852f420?sid=a16882db-abbb-45e6-9fff-ea499ecaec7c - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=50 ### 50. Orchaim Intelligent Open Router for Payments We’re building the MCP (Model Context Protocol) server for agentic shopping, enabling Future Shopping Agents from platforms like OpenAI, Visa, and Perplexity to safely initiate, reroute, and complete purchases with trusted payment orchestration and compliance logic. Our product empowers AI agents to manage shopping context, interpret agent-generated purchase intents, and orchestrate payment flows across processors like Stripe, PayPal, and Visa. When a processor fails, such as during a Stripe account freeze, our system intelligently reroutes the transaction, maintains compliance boundaries, and generates a full audit trail for trust and transparency. This enables autonomous shopping experiences with optional human-in-the-loop controls, allowing agents to operate reliably across a secure and resilient commerce execution layer. - **Team:** [Dhruv Miyani](https://cerebralvalley.ai/u/dhruvmiyani) - **GitHub:** https://github.com/DhruvMiyani/Orchaim-OpenAIGPT5 - **Demo video:** https://www.loom.com/share/456d6016e6a9446a89a1ec0e1adc52c4?sid=2a779092-cdc7-482d-8b60-96075d844bbf - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=51 ### 51.

We embed pilots + payload by nudging U/V chroma DC in fixed ROI blocks. Bits repeat across frames; decode uses pilot correlation with polarity flip and majority vote. The current decoder subtracts background (wm−bg). The notebook reports BER pre/post-encode and Δsize for IVF/MKV/WebM to quantify robustness vs. bitrate cost. Deepfake angle (today): this is not yet a cryptographic proof of authenticity. It’s a robustness watermark that lets us run provenance experiments: synthetic/edited segments often degrade the pattern—pilot correlation drops, BER spikes, or bits go missing—providing a practical signal to flag or down-rank at ingest. Roadmap: swap random payload for signed fields (stream ID, timestamp, rolling hash), add near-blind/pairwise decoding (no background), and wire real-time gating with monotonic-time checks. - **Team:** [Kyle Orciuch](https://cerebralvalley.ai/u/korciuch) - **GitHub:** https://github.com/edgetrace/verbose-parakeet - **Demo video:** https://github.com/edgetrace/verbose-parakeet/blob/main/explainer.mp4 - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=74 ### 74.

Agent-E : the glass‑box enterprise agent An enterprise agent that executes large document/data workflows by emitting tiny, sandboxed Python against a typed, allow‑listed SDK—batching/paginating work and streaming every tool action for audit and compliances like HIPAA and SOC2. Problem: Per‑item tool calls don’t scale (most default agents); black‑box autonomy fails governance and security (Manus , OpenAI Agent mode, etc). Solution: Restricted Python plans + typed I/O (validation) + sandboxed execution + live tool‑event stream. MVP (hackathon): Runtime that installs a minimal SDK and runs agent‑authored main(), with basic tools with streamed start/complete/error events; human‑readable call summaries. Demo: “Rename 4000 files based on their content and check for collision” → Agent‑E emits a short loop → executor runs it end‑to‑end with live progress. Positioning: Like OpenAI Agent Mode and Manus, but glass‑box: auditable code plans, enforceable tool allow‑list, resumable batches for enterprise workloads. - **Team:** [Karthik Ramasamy](https://cerebralvalley.ai/u/karthikv2k) - **GitHub:** https://github.com/karthikv2k/gpt5_hackathon - **Demo video:** https://loom.com/share/bf1b4264286a48efac00c7bcd574c12a - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=76 ### 76.

Bleu AI Bleu AI Bleuprint is a drag-and-drop, multimodal workflow builder powered by GPT-5 that lets users design complex AI pipelines without coding. By simply describing a desired outcome in natural language, GPT-5 generates and configures a graph-based workflow connecting text, image, video, and audio models. Users can also drag and drop components by creating nodes (AI models) and edges (context sharing). The system supports multi-step reasoning, context awareness, and structured outputs for easy integration. This project simplifies building end-to-end, agentic AI backends, traditionally a complex task requiring tools like LangChain, by providing a no-code interface where each node is a model and edges represent communication. By abstracting workflows into a single JSON format, it enables reliable, automated design and deployment of sophisticated AI workflows with minimal human effort. This means that vibe-coding a complex agentic workflow through our abstraction is now possible. - **Team:** [Joe Li](https://cerebralvalley.ai/u/jli505), [Matthew Li](https://cerebralvalley.ai/u/mattli), [Radostin Cholakov](https://cerebralvalley.ai/u/radicho) - **GitHub:** https://github.com/radi-cho/Bleu-OpenAI - **Demo video:** https://youtu.be/IRPat2FTGtA - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=82 ### 82.

Trialab Casual OS is an AI platform that turns natural-language specs into production-ready apps—and runs them safely at scale. It auto-generates architecture (DAG), code, tests, and a policy manifest (egress allowlists, data handling, budgets, SLOs). Apps execute in a zero-trust sandbox with audit logs, monitoring, and deterministic replay. A visual editor lets anyone refine UI/flows; developers can export clean TypeScript. Publish to a trust-badged marketplace with monetization. On the same platform, Casual Play enables rule-editable, competitive games (e.g., chess variants). Creators define rules in a safe DSL compiled to a deterministic, server-authoritative engine with fairness checks, anti-cheat, and replay/appeals. Skins and rules ship separately, so players customize looks without breaking integrity. - **Team:** [Viraj Sanghani](https://cerebralvalley.ai/u/VS95) - **GitHub:** https://github.com/VirajSanghani/openAI.git - **Demo video:** https://youtu.be/kG6ISjiOH7A - **Project:** https://cerebralvalley.ai/e/gpt5/hackathon/gallery?project=92 ### 92.
