Local-First AI

Deep dives and field notes on local-first AI, agentic architecture, and what is actually working in 2026, with primary sources and reproducible benchmarks.

Deep dives

Long-form research articles with primary sources, benchmarks, and reference tables.

Cost-Quality Pareto for Coding Agents (May 2026)

Paying $5 per task no longer gets you the frontier. Qwen3.6-27B running locally hits 77.2% SWE-bench Verified at ~$0.04/task, within 10pp of Opus 4.7 for ~130x less money.

Building an Eval Harness That Catches Regressions

Anthropic shipped three concurrent regressions over six weeks and their eval suite caught none of them. Even Anthropic ships blind. Here is the six-layer harness pattern that would have caught it.

MCP Server Audit: Which Ones Actually Work in 2026

Of the ~14,000 MCP servers in PulseMCP's hand-curated index, fewer than 30 are demonstrably production-ready. Here is the list, the criteria, and the failure modes.

Mixing and Matching Open-Weight Models: A Recipe Book

An 84% cost reduction on a real SaaS workload, a 97% reduction on agentic dev loops, and the three-tier mix that actually ships in May 2026.

The Multi-Agent Orchestration Frontier in May 2026

Nine frameworks, one durable-execution wedge, zero unbroken benchmarks. An honest map of the multi-agent ecosystem in May 2026, anchored in Anthropic's 90.2%/15× receipts and Berkeley's eight-benchmark exploit.

Field notes

AI Agent Conference NYC: 10 Takeaways

The 10 things from AI Agent Conference 2026 NYC (May 4-5, NY Hilton Midtown) that are actually load-bearing if you ship agents in 2026. The trust paradox, CrewAI's 42% AI-authored code, the iceberg under every project, AX as the new UX, and what the panels from Datadog, LanceDB, Carta, and the Codex/Linear/Graphite room actually said.

AI Dev SF: 10 Takeaways

The 10 things from AI Dev 26 SF (April 28-29, Pier 48) that are actually load-bearing if you build agentic systems in 2026. Marc Brooker on defects, Andrew Ng on PM bottlenecks, Bain's 8-subgraph payroll system, the 4-legged identity, hybrid doc OCR, and the simulation sandbox every action-taking agent needs.

Document OCR for Agentic Workflows

90% of enterprise data is locked in PDFs. The 2026 pipeline that gets it out is not RAG, not vision-only, and not the OCR you remember from 2018.
