Community Spotlight: April 2026

#community #opensource #contributors #multiagentorchestration

Every month we spotlight the people who make Bernstein better. Here are April's highlights from the first month of public development.

What happened in April

Bernstein went from v1.0.0 to v1.8.8 in a few weeks. The pace was intense, and community contributions made a real difference:

Architecture decomposition: 52 oversized modules broken into 22 focused sub-packages, each under 600 lines. The orchestrator monolith (4,198 lines) is now navigable, testable, and merge-conflict-free. Read the full story.
18 agent adapters: We started with 7 adapters and now support 18: Claude Code, Codex, Gemini CLI, OpenAI Agents SDK, Cursor, Aider, Amp, Kiro, Kilo, Qwen, Goose, Ollama, Cody, Continue, OpenCode, Cloudflare Agents, IaC, and a generic wrapper. Each adapter is a focused Python class under 200 lines.
Cost-aware routing: The contextual bandit router learns which model handles each task type best. In our own runs, the bandit cut spend roughly in half compared to sending everything to the same model.
Cloudflare cloud execution: Agents can now run on Cloudflare Workers with Durable Workflows, R2 artifact storage, and D1 state.
Windows support: Full cross-platform compatibility contributed by @oldschoola: environment passthrough, Unicode safety, process management, and terminal handling.
