VaporSpace

An infinite spatial canvas for architects and planners — powered by Nebius Token Factory, Nebius AI Cloud, and NVIDIA models.

Built With

🔑

Nebius Token Factory

Provisioning API credentials and managing authentication tokens for the VaporSpace backend service layer.

☁️

Nebius AI Cloud

Powering the LLM-driven content generation engine — flowcharts, database schemas, landing pages, presentations, and architecture notes.

🧠

NVIDIA Model (via Nebius)

Complex reasoning for multi-type content generation — turning a single user prompt into coordinated diagrams, schemas, wireframes, and slide decks simultaneously.

Tool Feedback

Every tool we used — what worked, what didn't, and whether we'd build with it again.

🔑

Nebius Token Factory

Provisioning API credentials and managing authentication tokens for the VaporSpace backend service layer.

Would build again
✓ Worked Well

Straightforward token issuance flow — once authenticated, the token was immediately usable for downstream API calls with no extra configuration.

⚠ Needs Work

The token lifecycle management UI could be more intuitive. Auto-refresh and rotation indicators would reduce manual monitoring.

🚀 Onboarding (0 → Hello World)

Zero to hello world took about 15 minutes. The initial setup steps were clear, though finding the right scope permissions required a doc dive.

💬 Why we'd build again

Reliable, fast token provisioning with minimal friction. It just works once configured.

☁️

Nebius AI Cloud

Powering the LLM-driven content generation engine — flowcharts, database schemas, landing pages, presentations, and architecture notes.

Would build again
✓ Worked Well

Low-latency inference, structured JSON output support, and excellent uptime. The spatial canvas AI assistant relies on it for every generation request.

⚠ Needs Work

Rate limiting feedback could be more granular — a 429 with a retry-after header would let the UI show precise wait times instead of generic error messages.

🚀 Onboarding (0 → Hello World)

Zero to hello world was impressively fast. The SDK integrated cleanly with our React/Vite frontend. Docs covered the common paths well.

💬 Why we'd build again

Performance and reliability are top-tier. The structured output feature alone saved us from building a custom JSON parser layer.

🧠

NVIDIA Model (via Nebius)

Complex reasoning for multi-type content generation — turning a single user prompt into coordinated diagrams, schemas, wireframes, and slide decks simultaneously.

Would build again
✓ Worked Well

Strong instruction following and coherent multi-format output. The model understood spatial canvas context and produced content that fit together as a cohesive workspace.

⚠ Needs Work

Occasional verbosity in intermediate reasoning steps that we had to trim for UI responsiveness. Temperature tuning for creative vs. structured tasks needed manual experimentation.

🚀 Onboarding (0 → Hello World)

Plugged into the Nebius AI Cloud endpoint — no separate SDK needed. Model selection and parameter passing were well-documented.

💬 Why we'd build again

Quality of multi-format generation is unmatched for this use case. A single prompt producing a full workspace of diagrams and docs is the core value prop of VaporSpace.

Submission Tips

A stronger submission checklist.

Name your project like a human

VaporSpace — not "spatial-canvas-ai-v2". Memorable, meaningful, and tied to what the app actually does.

Hide your API keys

Never put API keys directly in code. Use environment variables, add .env to .gitignore, and check your repo before submitting.

Make required tools impossible to miss

Name Nebius Token Factory, AI Cloud, and your NVIDIA model in the project description, Built With section, and demo video — with audio.

Treat your video like a pitch

3 minutes: lead with the problem, show the solution working, tell judges who it's for and how it uses Nebius + NVIDIA.

Call out tools with audio

Don't just show a logo — say it out loud. "We use Nebius AI Cloud with NVIDIA models for every generation" lands harder than a passing mention.
