Case study
Twenty thousand prompts across 50 languages in an accelerated evaluation sprint.
A model team needed 20,000 prompts evaluated across 50 languages under a compressed decision window, where the fine-tuning decision could not wait on a slow evaluation bench.
50 - ~20,000 prompts - reviewed quality
Project overview
What landed, and what made it hard.
A model team needed 20,000 prompts evaluated across 50 languages under a compressed decision window, with five evaluators per language working in parallel.

Why this mattered
Outcome before process.
Evaluation at this speed is a sourcing and calibration problem: 50 languages cannot ramp sequentially, and compressed decision windows leave no room to re-train evaluators mid-sprint.
The problem to solve
Why the work was difficult, and what MoniSa changed in-flight.
A compressed 50-language evaluation fails if calibration is uneven across languages, if any language track lags, or if quality is traded for speed under the deadline.
The challenge
The problem to solve
A compressed 50-language evaluation fails if calibration is uneven across languages, if any language track lags, or if quality is traded for speed under the deadline.
The team needed all 50 languages evaluated to one standard inside the sprint, not a fast average that hid weak language tracks.
Operating response
What MoniSa changed
MoniSa sourced five calibrated evaluators per language and ran all 50 tracks in parallel against a shared rating framework, with quality checks through the sprint.
- Parallel sourcingFive evaluators per language ran simultaneously so no track waited on another.
- Pre-calibrationEvaluators were calibrated against the rating framework before the sprint started, not during it.
- In-sprint checksQuality was monitored through the sprint so speed did not quietly trade against accuracy.
Results
Measured outcomes from this engagement.
The team received ~20,000 prompt evaluations across 50 languages during the accelerated sprint at reviewed quality, with every language held to the same standard.

Selection logic
What protected the result.
A compressed 50-language sprint needs parallel pre-calibrated sourcing, not a bench that ramps languages one at a time.

What buyers can reuse
What buyers can reuse
- An accelerated multilingual evaluation is a sourcing and calibration problem solved before the sprint, not during it.
- Speed is only useful if every language track holds the standard, not if a fast average hides weak ones.
- The evidence keeps the client details confidential and attributes the metrics only to this engagement.

Legal translation into Khmer
The challenge. A global marketplace needed 250,000 words of legal content translated into Khmer for market entry.
What we did. MoniSa sourced legal-literate Khmer linguists with a separate review pass and terminology control.
The result. The marketplace received 250,000 words of legal Khmer translation and review.
Multi-device subtitle QC
Problem. A media catalog needed subtitle QC verified across five device types and four languages.
Action. MoniSa ran QC against a per-device checklist with native reviewers per language.
Result. The catalog received 500+ hours of subtitle QC with reviewed quality across Mac, Windows, mobile, iPad, and OTT.
AI assistant prompt data
Problem. A top-10 technology company needed 85,000 prompt recordings across 20 languages for an assistant launch.
Action. MoniSa sourced diverse speakers across 20 languages and regional variants with per-recording QA.
Result. The company received 85,000 prompt recordings across 20 languages and regional variants.
