SyntheholDB

What it does

SyntheholDB is a relational synthetic database generation engine. Describe your schema in plain English or start from templates and CSVs. Get linked tables with referential integrity, built-in privacy and quality checks, and real-time generation. Export to PostgreSQL, MySQL, CSV, or Parquet.

Generate test databases that obey your foreign keys and flag PII before export. AI builds the schema, fills 50k+ linked rows, and gives you CSVs ready for dev, demos, and CI - in under a minute.

  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…
