Every Apple Silicon Mac ships with a 3-billion-parameter language model locked inside Apple's Foundation Models framework. Apfel is a native Swift tool that cracks it open, exposing it as a UNIX CLI, an interactive chat client, and an OpenAI-compatible HTTP server — all running locally on your Neural Engine, no API keys required. Built in Swift 6.3 using LanguageModelSession, Apfel installs via a single brew command. It supports MCP (Model Context Protocol) natively for tool calling across all modes. Every token runs on-device with nothing leaving your machine. It requires macOS 26+ on Apple Silicon. Apfel cleared 513 points and 117 comments on Hacker News, making it one of the most-discussed indie AI releases of April. For developers who just want a fast, always-available local model that costs nothing per token and never phones home, Apfel is a genuinely useful tool. The model isn't frontier-quality, but for code summarization, quick answers, and workflow automation it punches well above its weight.

CodeBurn is a terminal TUI dashboard that reads AI coding session data directly from disk — no API keys, proxies, or wrappers required — and surfaces a breakdown of token costs across Claude Code, Codex, Cursor, GitHub Copilot, and more. It auto-classifies activity into 13 categories (coding, debugging, testing, refactoring, etc.) and shows one-shot success rates per task type, giving developers a rare look at where their AI spend actually goes. The dashboard includes gradient charts, keyboard navigation, multiple time periods, and a currency converter supporting 162 ISO 4217 currencies. There's also an "optimize" command that scans sessions for waste patterns and outputs actionable, copy-paste fixes. For teams, a macOS menu bar app surfaces daily costs at a glance. With 2.7k stars after a Show HN post, CodeBurn clearly scratched a real itch. As AI coding budgets scale from hundreds to thousands of dollars per developer per month, tooling that makes costs visible and actionable becomes less optional and more essential.
Reviewer scorecard
“This is exactly the right abstraction — the model was already there, we just needed a pipe. The OpenAI-compatible server means every tool in my stack can use it without modification. Brew install and you're done.”
“This is exactly the observability layer AI coding has been missing. Knowing that 40% of my Claude Code tokens went to a single poorly-scoped context window is the kind of insight that pays for itself in the first week. The 'optimize' command is genuinely useful, not just marketing copy.”
“Apple's Foundation Model is a 3B parameter model optimized for Siri-style tasks, not complex reasoning. Don't expect Claude-tier quality from this — for serious dev work, you'll hit its limits within minutes and end up back on a paid API anyway.”
“The multi-provider claim is impressive on paper, but Cursor and Copilot don't expose session data the same way Claude Code does. Expect incomplete data for non-Anthropic tools until the provider ecosystem standardizes telemetry formats. Also: if your team uses ephemeral dev containers, good luck getting disk reads to work.”
“Apfel is a preview of a future where capable models are ambient in every device. As Apple updates its Foundation Model, Apfel's capabilities grow for free. The infrastructure investment is zero.”
“Cost observability is the missing infrastructure layer for the AI-native development era. Just as APM tools like Datadog became mandatory once cloud costs mattered, AI coding cost tracking will be table stakes within 18 months. CodeBurn is an early mover in a category that will consolidate around one or two dominant players.”
“For quick drafts, caption rewrites, and local scripting — things that don't need GPT-4 quality — having a zero-cost model in my terminal is genuinely useful. No privacy concerns, no billing surprises.”
“The TUI design is clean and keyboard-navigable in a way most developer dashboards aren't. Gradient charts inside a terminal window sounds tacky but actually reads well. The category breakdown would make a genuinely compelling weekly standup artifact for teams trying to improve AI workflow discipline.”
