• #1622 0706a1f5 Thanks @amh4r! - Fix step.run not JSON-serializing during checkpointing

AI Metadata field names have been renamed to align with OpenTelemetry GenAI standards: .model is now .request_model and .system is now .provider. Insights queries using the old field names must be updated. AI Metadata extraction now differentiates between request and response models when using ai.step.wrap or ai.step.infer.

Added experiment and sessions endpoints to the REST V2 API and CLI, including GET endpoints for experiments, sessions, and session runs. Also fixed a V1 execution engine regression that was coalescing parallel steps incorrectly, visualized numeric metrics using box plots, and showed key queues settings in the function view.

Sessions make it easier to investigate related work across your environment. When sending events, attach a stable session key and ID with meta.sessions, then use the Sessions page to jump from a domain concept like a conversation, support ticket, or import to the runs it…

Scoring lets you attach a named quality signal to a function run, a step, or an experiment variant. It shines for AI evals: run an LLM-as-a-judge over a result and write the verdict back as a score with inngest.score({ name, value }), or defer the judge entirely so a slow…

• (sessions) Allow sessions in invoke button (#4489)
• Insights ai experiments updates (#4492)

🚜 Refactor

• (queue) Make Producer configurable in Queue (#4078)
