Platform · Private / developing
A guided workspace for the parts of evaluation that repeat.
The platform lets a product team run the repeatable evaluation workflow themselves: analyse a prompt, build and review test cases, run models under equivalent conditions, inspect failures, and compare a baseline with a candidate before deciding what ships.
It is private while the workflow is validated in real service engagements. We do not automate a step until it has stayed substantially the same across several real customers.
What it does today
Five stages, one decision.
The stages mirror the method used in every Spring Prompt engagement, so evidence produced in the platform reads the same way as evidence delivered by hand.
-
01
Prompt analysis
Read the prompt, its variables and its context as one system. Surface the criteria it implies and the failure modes it invites.
-
02
Test cases
Author representative cases and consequential edge cases, import your own, and review every case before it counts.
-
03
Model runs
Run prompts, models and configurations on the same cases under equivalent conditions, with cost and latency recorded per run.
-
04
Failure inspection
Read the actual outputs with their check results and judge reasoning. Flag, annotate and turn confirmed failures into regression cases.
-
05
Comparison and decision
Compare baseline and candidate side by side, keep critical failures and unresolved cases visible, and export a decision report.
Current limitations
The workflow is text-focused.
The platform evaluates text outputs from prompts, models and configurations. It does not yet execute the surrounding system. Where your product depends on one of these, the evaluation is delivered as a service instead.
Not yet executed by the platform
-
Tools
Function calls and tool-using loops are not executed.
-
Retrieval / RAG
Retrieval pipelines are not run; retrieved context can only be supplied as fixed input.
-
Browser actions
No browsing, clicking or form-filling.
-
Audio
No speech input or output.
-
Complete agent workflows
Multi-step agent trajectories with environment state are out of scope.
How it relates to services
Services first, then the platform absorbs what repeats.
-
01
Managed engagements
Spring Prompt runs evaluations manually for a small number of design partners and learns which steps are hard, which need expertise and which repeat.
-
02
Internal operator workbench
Software makes Spring Prompt's own delivery faster and more consistent before anyone else touches it.
-
03
Assisted, private platform
Selected clients run the repeated workflow themselves while Spring Prompt still guides evaluation design. This is the current stage.
-
04
Recurring release gate
If demand proves recurring: integrations, automatic sampling, regression checks, alerts and API or CI checks.
Services do not disappear as the platform matures. They remain the high-touch layer for custom evaluation design, sensitive deployments and expert review.
Access
Request access, or start with an evaluation.
Access is granted in small groups while the workflow is validated. If your first evaluation depends on tools, retrieval or agent workflows, a service engagement is the right starting point.
