Parallel branches now share one checkout, and join_policy was removed. Remove join_policy from parallel nodes; fan-out now waits for every branch. Keep file-writing branches read-only or assign disjoint paths, and update fan-in logic to consume parallel.results instead of a selected branch workspace or parallel_results.json.

​
Shared-checkout parallel execution

Parallel branches now run concurrently in the run’s existing sandbox and working directory instead of creating branch-specific Git worktrees. Each branch still receives isolated context updates, returned in outgoing-edge order under parallel.results, while a prompted fan-in can synthesize the complete typed result array. Promptless fan-in nodes act as barriers and never select, restore, or merge workspace state.

Fireworks AI

Fireworks AI is now an opt-in built-in provider with a curated serverless catalog for Kimi, DeepSeek, GLM, MiniMax, Qwen, and GPT-OSS models. The integration uses the existing OpenAI-compatible path, supports cached-input accounting, and works with the normal provider login, secret storage, diagnostics, and model-testing flows.

Resumed stages keep their history

When a run resumes after a node was cancelled or lost mid-flight, the replay now starts a new stage execution such as work@2 instead of clearing and reusing work@1. The earlier execution keeps its events, session, output, timing, billing, and terminal state, and the stage UI links the new execution back to the one it resumed from.

  • GET /api/v1/runs/{id}/events now supports descending cursor pagination with order=desc and before_seq; fabro run events --tail uses it to fetch only the newest events
  • Completion usage now reports disjoint input, output, reasoning, cache-read, and cache-write token buckets
  • Model responses now advertise exact controls.reasoning_effort values, and completion requests—including structured completions—validate and forward reasoning effort with a 400 response for unsupported values
  • Event history scans now use seek-based pagination with bounded cursors, avoiding full-history work and incorrect results for oversized sequence values
  • Preflight now prefers providers that are actually ready while preserving explicit provider pins and useful diagnostics for unavailable offerings
  • OpenAI-compatible agent providers now receive compatible file-edit and tool schemas
  • Large values inside parallel branch results now stay available to fan-in prompts through normal artifact storage
  • Added claude-opus-5 to the first-party Anthropic model catalog; the opus and claude-opus aliases now resolve to Opus 5
  • Added gpt-sol, gpt-terra, and gpt-luna aliases for GPT-5.6 offerings
  • Added portable glm, glm52, glm5.2, deepseek, and deepseek-flash aliases across direct and OpenRouter offerings
