The proposed Free / Premium split

The essentials stay open.
The workflow gets smarter.

Experiments are part of the core product. Premium is about going deeper and reducing repetitive work, not putting every AI judge behind a paywall.

Product direction only. Premium capabilities below include planned work, not a promise of availability today.

Premium roadmap

Find what failed.
Generate a test. Prove the fix.

Production alerts, spending controls, bounded sweeps and team review are implemented. Other improvement workflows below remain planned. Labels distinguish working capabilities from roadmap direction.

Implemented · bounded sweeps

Explore the configuration space

Advanced experiments

Queue pinned prompt/model/HTTP-agent variants and repeated trials. Compare quality, latency and known cost with exploratory paired confidence intervals; incomplete runs block conclusions. Retrieval variants require separately configured agent targets.

Planned

Find the recurring pattern

AI failure analyst

Group recurring failures, suggest likely causes, and link findings to trace evidence. Treat explanations as hypotheses to verify, not automatic diagnoses.

Premium · Stripe subscription

Generate. Review. Run. Evaluate.

AI-generated test cases

AI-written questions and suggested references are available with a synced Premium subscription. Entering your own questions, automatic HTTP agent runs and basic semantic AI judging are available on Free. Automatic failure-based test generation remains planned.

Planned

Make the rubric clearer

Evaluation copilot

Get help drafting evaluation criteria and investigating disagreements between AI judges and human reviewers. Keep final rubric changes under human control.

Planned

Suggest. Benchmark. Review.

Prompt optimization

Generate candidate prompts and compare quality, cost, and latency through experiments. Recommend a change only after checking regressions; never auto-promote it.

Planned

Prove the change before release

CI regression gates

Run agreed checks in pull requests, report baseline/candidate differences, and block releases when quality thresholds regress. Require approval for important changes.

Implemented · configure worker

Keep watching production

Continuous quality monitoring

Sample incoming traces, run background checks, and monitor quality failure rates. Deliver issue transitions by email or signed webhook, with atomic daily/monthly AI dollar budgets and a reviewed built-in model catalog.

Implemented · in-app invitations

Improve together

Team review workflows

Share private team workspaces with Owner/Admin/Editor/Reviewer roles, assigned trace reviews, authenticated review attribution and action history. Existing verified accounts accept invitations in the app. No SSO or enterprise SLA is implied.

Planned

Spend where it helps

Cost optimization insights

Identify expensive calls and excessive tool loops. Suggest cheaper configurations to benchmark against your quality baseline before switching models.

Experiments at the center

A recommendation is not a release.

Keep datasets and evaluation criteria fixed, compare per-example results, and review cost and latency. Automated suggestions should lead to an experiment and a human decision, not an unreviewed deployment.

Explore experiments
Advanced evaluation in the Premium direction

More than a score.
A reason to make the next change.

Go beyond a basic manual judge with calibration and evidence-based evaluation. Existing evaluators depend on deployment configuration; the proposed plans do not gate access today.

Implemented · structured captured turns

Conversation quality

Judge resolution, coherence and observed user frustration across captured conversations. Authorized HTTP-agent experiments replay sequential turns and retain candidate evidence; flattened or one-shot outputs do not masquerade as multi-turn runs.

Implemented · evidence-based, not certification

Safety sample checks

Evaluate observed toxicity and prompt-injection resistance with captured evidence, plus deterministic exact-sensitive-literal leakage against explicit ground truth. Missing or partial evidence stays unavailable; these checks do not certify safety or compliance.

Implemented evaluation workflow

Agent Quality

Score task completion, error recovery, required tools, exact tool arguments, tool-call budgets, and repeated calls against pinned experiment evidence. AI judges require configuration and consent.

Implemented with human review

Pairwise preference

Judge baseline and candidate outputs in both presentation orders, retain ties and disagreements, and review pinned evidence. Approval requires human decisions and passing candidate quality scores; it never deploys a change.

Align AI and human judgment

Judge calibration

Compare judge results with human scores, inspect disagreements, and tune thresholds with evidence. Basic AI judging is available on Free when configured.

Evidence, not guesswork

Groundedness

Check whether response claims are supported by captured documents. Surface unsupported statements instead of trusting a convincing answer.

On-topic responses

Answer relevance

Use a model-based judge to assess whether the response addresses the user's actual question, beyond exact wording or keyword matches.

Check the claim, not just the link

Citation support

Look beyond valid citation IDs. Evaluate whether the referenced documents actually support the claims they accompany.

Better context, better answers

Retrieval relevance

Judge whether retrieved documents are useful for the question. Separate helpful context from results that only look similar.

Understand the whole run

Agent evidence review

Review tool use, failures, missing evidence, and uncertainty before a final quality judgment. Evaluate the path, not just the final response.

Keep quality in the loop

Bring AI judges to incoming traces.

Background evaluation rules can apply your criteria to new runs. Keep dataset versions, judge criteria, and model choice explicit so results stay interpretable.

Create your workspace

AI judgments are signals, not guarantees. Results depend on the judge model and available evidence. Review important decisions with a human.

Premium upgrade

Upgrade to Premium

Subscribe without leaving Tracework. Payment details are collected securely by Stripe in the embedded checkout below.

Premium is granted only after the server retrieves an active or trialing subscription directly from Stripe. Manual questions, automatic agent runs, basic AI judging and captured-evidence workflows remain available on Free with configuration and consent.

Monthly host fee

Keep an agent hosted

A saved agent stays available for as long as this subscription is paid. There is no other time limit. Scratch tests still expire. Cancelling the host fee keeps the saved agent and stops new runs until hosting is paid again.

A little more clarity

Good questions.
Straight answers.

What the plans mean, how experiments and evaluation work, and what is available today.

What is the difference between Free and Premium?

Free lets you enter test questions, run a configured agent, capture its answers and latency, and evaluate their meaning with a basic AI judge. References are optional; judging criteria and consent are required. Provider charges and operator budgets apply. Premium adds AI-written test questions for workspaces with a synced active Stripe subscription. Other Premium descriptions remain product direction.

How are experiments different from evaluations?

An evaluation scores an answer or run. An experiment executes a specific prompt, model, or agent configuration against a fixed dataset so you can test a change. Compare baseline and candidate runs with the same dataset version, evaluator, thresholds, and criteria, then inspect quality, regressions, latency, and recorded usage.

Which Premium workflows are available today?

Tracing, versioned datasets/prompts, Agent Quality, pairwise review, conversation/safety sample checks, bounded sweeps and team review are implemented. Background checks, alerts and hard AI dollar controls require operator configuration. Task-based AI case drafts are available to Premium workspaces. Automatic failure-based tests, failure grouping, evaluation copilot, prompt optimization, integrated PR gates and AI cost recommendations remain planned. Confidence is exploratory and safety checks are not certification.

Can I purchase Premium now?

Yes, when Stripe is configured for this deployment. Sign in, complete the embedded Stripe checkout, and Tracework will retrieve and sync the resulting subscription before enabling Premium.

Are model-provider costs included?

No included AI allowance is promised. AI evaluation requires operator-enabled model access and explicit approval to send the selected data and accept provider usage charges. Creating an account does not enable paid model calls.

Do AI judges need access to my agent's data?

Yes. Depending on the evaluator, selected inputs, outputs, reference answers, retrieved documents, or tool evidence are sent to the configured model provider. Review the data before consenting. Deterministic checks do not require a model call.

Does Premium introduce evaluation limits?

No plan-specific quotas are enforced. Operator and workspace AI dollar safety budgets, request/provider limits and storage constraints still apply. Models missing from Tracework's built-in price catalog remain blocked. These controls are not subscription allowances.
