Flow

Salesforce Flow engineering: record-triggered flows (before-save fast field updates, after-save related-record automation, before-delete), entry conditions and $Record__Prior, decisions and formulas, Custom Error, fault paths, subflows, autolaunched flows called from Apex, invocable Apex actions, scheduled paths, and choosing between flows and Apex triggers. Answers are Flow metadata files (API 67.0) deployed check-only to a clean scratch org, where hidden Apex tests do DML (including 200-record bulk tests that assert on Limits) and check the outcome.

How it's graded

Flow metadata is deployed as a check-only validation to a clean scratch org, where hidden Apex tests do DML (including 200-record bulk tests that assert on governor limits) and check the outcome. Decision-guide questions (flow or Apex?) are multiple choice.

      What's in the suite

      Solve rate is the share of finished runs whose first answer to the task passed (pass@1), a rough guide to how hard models find it. Difficulty is the task author’s label; from results is what the solve rate says: easy when two thirds or more of the finished runs pass it, hard at a third or fewer, once five have graded it.

      Want this for your team?

      Azul Labs runs Forcebench privately for two kinds of Salesforce team.

      Choosing a model to run yourself?

      A private benchmark of your shortlist

      Open-weight models at the quantisations and reasoning efforts you could run on infrastructure you control, tested on your kind of Salesforce work, with a written recommendation.

      • Private tasks written from your work only ever run on local models; they are never sent to an API.
      • Re-testing after any change of model, quantisation or engine is available.
      • Typical turnaround is 2–3 weeks; large models take about a day of machine time per configuration.

      Building or buying a Salesforce AI tool?

      A private evaluation of your tool

      Your tool on held-out tasks it has never seen, against API baselines (models reached through a hosted service) and Local ones (served on Forcebench’s own hardware), with a written report on where it holds up and where it fails.

      • It can start as a smaller pilot, about 30 held-out tasks with your tool against two baselines, before a full evaluation.
      • Repeat evaluations after your releases are available.
      • Typical turnaround is 2–3 weeks.

      Fixed fee, quoted up front. The quote depends on the number of tasks and the number of models, tools or configurations tested.
