Prometheus AI

What it does

Prometheus AI is an open-source prompt engineering workspace. Paste your rough idea, pick your target model (Claude, ChatGPT, Gemini, Grok, Mistral, Perplexity), and get a structured, expert-grade prompt — optimized with model-specific rules and 60+ use case subcategories. Bring your own API key. Self-hosted. No account. No data stored. MIT license.

Transform raw prompts into precise, expert-grade prompts with a server-first Next.js app.

Transforme une intention brute en prompt expert. Connecte ta propre clé API, choisis ton fournisseur, et garde le contrôle de tes crédits. Ta clé reste dans ton navigateur. Prometheus l'utilise uniquement pour transformer tes prompts — tu paies directement ton fournisseur. Enregistre d'abord une clé API valide pour débloquer lefrom prometheus-ai-dev.vercel.app

  Create your own finetuned AI model using Google Sheets2025 · promptrepo.com · ▲137

  Hello HN, We built Promptrepo to make finetuning accessible to product teams — not just ML engineers. Last week, OpenAI’s CPO shared how they use fine-tuning for everything from customer support to deep research, and called it the future for serious AI teams. Yet most teams I know still rely on prompting, because fine-tuning is too technical, while the people who have the training data (product managers and domain experts) are often non-technical. With Promptrepo, they can now: - Add training examples in Google Sheets - Click a button to train - Deploy and test instantly - Use OpenAI,…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
