Needle is a tiny 26-million-parameter language model built specifically for function calling—the task of deciding which tool to invoke based on a user's natural language request. Developed by Cactus-Compute and released under MIT, it was pretrained on 200 billion tokens using 16 TPU v6e chips, then post-trained on 2 billion curated function-call examples distilled from Google's Gemini 3.1. The result: a model small enough to run on a phone or smartwatch that can reliably pick the right tool with sub-100ms latency. The architecture is called a "Simple Attention Network" and deliberately strips away generative capabilities, focusing entirely on routing accuracy. You hand Needle a list of available tools and a user query, and it outputs a structured JSON function call—nothing more. This keeps the binary tiny, the inference fast, and the memory footprint under control on edge hardware. Why does this matter? Today's personal AI assistants require a round-trip to the cloud for every tool dispatch, adding latency and raising privacy concerns. Needle makes it possible to keep that decision-making on-device, calling the cloud only when the tool itself requires it. It's early (258 GitHub stars today, trending hard), but the idea of a dedicated tiny router model is compelling enough that several phone OEMs are reportedly experimenting with it.

Seeknal
Data & ML CLI where you define pipelines in YAML and query them in natural language

Seeknal is a Data & ML CLI designed for teams running agent-driven data pipelines. The core workflow follows three verbs: Organize (define pipelines in YAML or Python), Expose (materialize data to PostgreSQL and Apache Iceberg), and Action (query and transform data in natural language). It uses a draft, dry-run, apply progression that gives teams control before changes hit production. The natural language query layer is what sets Seeknal apart from standard data pipeline tools. Instead of writing SQL to explore a freshly materialized table, you describe what you want — and Seeknal translates that to the appropriate query against your Postgres or Iceberg target. The combination of structured pipeline definition (YAML/Python) with flexible natural language exploration is designed for the reality that data teams include both engineers who want explicit control and analysts who want fast iteration. The 'built for the agent world' framing reflects a genuine architectural choice: Seeknal's API is designed to be called programmatically by AI agents, not just by humans with keyboards. This matters because data pipeline management is increasingly something agents need to do autonomously — fetching fresh context, materializing results, and querying outputs — without human intervention at each step. Seeknal launched on Product Hunt today targeting teams that have adopted agentic workflows but still treat their data infrastructure as human-operated.
Reviewer scorecard
“If you're building any kind of personal agent or on-device assistant, Needle solves the tool-routing problem cleanly. The MIT license and Hugging Face weights make integration straightforward—drop it in, point it at your tool list, done.”
“The draft, dry-run, apply workflow is the right abstraction for data pipelines that agents touch — you want to see what's going to happen before it materializes to production Iceberg. The natural language query layer saves me from writing boilerplate SELECT statements to verify pipeline output, which is maybe 30% of my current pipeline debugging time.”
“258 stars and 8 forks isn't exactly a battle-tested library. It's a research preview that hasn't been stress-tested on diverse real-world tool schemas. Wait for benchmarks from third parties before trusting this in production.”
“Natural language to SQL is still unreliable for complex queries — hallucinations in your data pipeline output can corrupt downstream analysis silently. The Iceberg and Postgres combo covers a lot of use cases but excludes BigQuery, Snowflake, and Databricks users who make up a huge chunk of enterprise data teams. This feels more like an impressive demo than a production-ready CLI.”
“Dedicated micro-models for specific reasoning subtasks is the architecture path forward. Needle hints at a future where your device runs a dozen tiny specialists rather than one giant generalist—dramatically better for privacy, latency, and battery life.”
“Data infrastructure that agents can operate autonomously is one of the key missing pieces in the agentic stack. Today's agents are smart enough to reason about data but lack the tooling to materialize and query it reliably. Seeknal is early infrastructure for fully autonomous data agents — the kind that can ingest, transform, and query without a human in the loop.”
“The idea of AI assistants on wearables that actually respond instantly instead of spinning for 3 seconds on every request is genuinely exciting for creative workflows—imagine voice-triggering design tools from your watch without a cloud hop.”
“This is firmly in the backend infrastructure category — the YAML pipeline definitions and Iceberg targets are beyond what most creator-focused teams need. For analytics on content performance or audience data, there are simpler options. Seeknal's complexity is justified for data engineering teams but overkill for creators.”
