Next.js 16 + React 19 App Router Workbench• Live on Coolify

Next-Generation Multi-Model AI Studio

Benchmark frontier LLMs side-by-side, stream reasoning traces in real-time, engineer reusable prompt templates, and orchestrate multi-step agent pipelines.

Self-Hosted Demo Environment: LLM streaming and reasoning tokens are simulated server-side to benchmark Next.js 16 App Router performance and Coolify deployment without external API keys.
Models:
Claude 3.7 Sonnet
GPT-4o Omnimodal
DeepSeek R1
Gemini 2.5 Pro
Llama 3.3 70B Turbo

Side-by-Side Dual Runner

Run identical prompts against Claude 3.7, GPT-4o, or DeepSeek R1 simultaneously. Compare latency, TTFT, token cost, and output quality in real time.

Live Extended Thinking

Transparent reasoning token visualizer with collapsible thinking traces, live stream cursor animations, and real-time generation speed counters.

Chained Multi-Step Agents

Orchestrate autonomous agent pipelines where step outputs are extracted, audited, and synthesized sequentially with structured variables.

Featured Prompt Templates

Curated system prompts powered by React 19 optimistic upvotes & Server Actions.
