Every Apple Silicon Mac running macOS 26 Tahoe already has a ~3B parameter LLM installed — the same model powering Siri and Apple Intelligence. Apple just doesn't expose it to developers. Apfel is a MIT-licensed Swift CLI that unlocks it: run it as a pipe-friendly command, an interactive chat session, or a local HTTP server at localhost:11434 that's fully OpenAI SDK-compatible. Any existing codebase using the OpenAI client can point at it with a one-line config change and start using free, private, offline inference with zero API keys, zero cloud, and zero subscriptions. The feature set is surprisingly complete for a developer side project. Apfel supports MCP tool/function calling, streaming JSON output, file attachments, five context-trimming strategies for the 4,096-token window, and a companion ecosystem of apps (apfel-chat, apfel-clip, apfel-gui). With 4,138 GitHub stars in under three weeks — fueled by a 513-point Hacker News thread — it's clearly filling a real gap that Apple intentionally left. The constraints are real: macOS 26 Tahoe required, context window capped at ~3,000 words, and the model is not going to replace GPT-4 for complex reasoning. But as a privacy-preserving local LLM for scripts, quick queries, code reviews, and offline workflows, it's genuinely compelling. The underlying model is already sitting on tens of millions of machines. Apfel is just the key to the door Apple forgot to install.

RisingWave's agent-skills package injects streaming SQL expertise into 18 AI coding assistants (Claude Code, GitHub Copilot, Cursor, Windsurf, and more) via the agentskills.io open spec. It ships two skill modules: core RisingWave connectivity and 14 best-practice rules covering CDC ingestion, materialized view patterns, time-windowed aggregations, and common pitfalls. Install via npm CLI which auto-detects which agents you have installed. Apache 2.0 licensed.
Reviewer scorecard
“If you have an M-series Mac running macOS 26, this is an immediate install — drop-in OpenAI compatibility means you can start running local inference against existing projects in literally 5 minutes. The MCP support and file attachment handling make it genuinely useful for scripted workflows, not just chat. The token limit stings, but for most dev automation tasks 3K words is plenty.”
“AI coding assistants hallucinate streaming SQL constantly — CDC ingestion patterns, windowed aggregations, and materialized view semantics are all places where generic training data fails hard. An installable skill package that auto-detects your agents and patches in correct context is exactly the right fix. Worth adding if you're building on RisingWave.”
“Apple hasn't documented this API surface and could close it in any future OS update — you're building on sand. The 4,096-token context cap is genuinely painful in 2026 when frontier models offer 128K-1M+ tokens, and a 3B parameter model will simply fail on complex reasoning tasks where you'd actually want privacy. For casual queries the privacy angle is real; for serious workloads you'll hit the ceiling fast.”
“This only matters if you're already using RisingWave, which is a niche streaming SQL database with a much smaller user base than Postgres or Kafka. Four stars on GitHub suggests the audience is narrow. The agentskills.io spec is interesting as a standard but it's vapor if no one else adopts it.”
“Apple shipped a capable on-device LLM to hundreds of millions of devices and then locked the door from developers. Apfel is the community's answer, and the 513-point HN reception suggests this is exactly what devs were waiting for. When the local AI model is free, private, and already installed, the adoption math changes — this is a preview of what happens when AI inference costs hit zero for common use cases.”
“Every database, framework, and specialized API is going to need its own skill package for AI coding agents. RisingWave is just the first mover on an inevitable pattern. The open spec is the actually important thing here — it could become how the entire ecosystem teaches agents about domain-specific tools.”
“For copywriters, note-takers, and creative folks on Apple Silicon who want local AI assistance without a monthly subscription, this is a quiet win. It's not going to write your screenplay, but for draft refinement, summarizing notes, generating quick variations, or building personalized offline tools — having free, private inference on your laptop changes the calculus entirely.”
“Not really in my wheelhouse — streaming SQL and data pipelines are developer infrastructure. But the 'teach your AI assistant the local dialect' concept is one I'd love to see applied to design systems, component libraries, and brand guidelines. Someone should build this for Figma.”
