What happens to your prompts?

Reviewed
Plan Scope
Current paid Pareto plans; the previously free seven-day evaluation is no longer advertised.
Prompt Retention
Prepaid/PAYG: processing only except legal/security/abuse retention up to 30 days. Personal/Max: up to 30 days for debugging and product improvement; saved chat/workspace content until user deletion or account termination plus 30 days. ZDR traffic has no post-inference content retention, including abuse logs.
Response Retention
Same plan-specific schedule as prompts; existing processing logs age out within 30 days rather than being immediately purged after account deletion.
Ordinary Logging
Account, request, usage, security, and abuse-prevention metadata are processed; the public terms do not provide a complete field-level retention schedule.
Model Training
Prepaid and ZDR content is not used for model training or improvement without written consent; subscription content may support debugging/product improvement under its plan terms.
Product Improvement
Personal/Max content can support product improvement for up to 30 days; aggregate non-content operational analysis is permitted.
Human Or Operator Access
Prepaid content access requires explicit consent or legal necessity. Subscription support/debugging access is limited to logged authorized employees. ZDR traffic is not accessible after inference.
Subprocessors And Routing
Requests may be routed through disclosed subprocessors and model providers including AWS, Anthropic, OpenAI, and xAI, subject to the selected route and onboarding terms.
Deletion Controls
Saved content can be deleted and account termination removes saved content within 30 days; operational logs expire on their rolling retention schedule.
Caveat
These current paid-plan policies must not be presented as terms for the discontinued free evaluation.

Before you build with Unbiased Pareto

Read the classification narrowly

No current provider-funded hosted inference offer was verified for this record. The label describes the bounded offer supported by evidence on 2026-10-06; it does not guarantee permanence, production suitability, uptime, latency, model quality, or access from every region.

Resolve the live model route

This snapshot records 1 model ID. Match the exact ID against the provider's live catalog before using it in code; zero-price routes and aliases can rotate while an older documentation page remains online. No stable base endpoint is published in this record, so use the linked provider documentation to identify the current request URL and protocol.

Confirm account and billing boundaries

An account is required, so public catalog evidence cannot by itself prove the limits, balance, or billing behavior attached to your workspace. The reviewed evidence explicitly says no payment card is required. Re-check the signup flow because eligibility and billing controls can change after the snapshot. The equivalent paid value shown here prices a documented allowance where possible; it is not cash, guaranteed savings, or protection from overage.

Re-read the prompt policy for your plan

This record classifies the reviewed handling as “Partially private”: Privacy protections are incomplete, conditional, or not fully documented. Provider policies can distinguish free, paid, enterprise, opted-in, and feature-specific traffic, so verify the governing terms for the exact account and route that will receive your data.

Follow the evidence, then re-check it

The record links 4 first-party sources covering the offer, catalog, limits, pricing, terms, privacy, or adoption evidence available to the audit. Prefer the newest governing document or live catalog when sources disagree, and submit a correction when a provider changes a material term.

Match the quota to the workload shape

Translate the published allowance into the traffic pattern you actually expect instead of comparing headline totals alone. A daily token pool can look generous while a low requests-per-minute or concurrency ceiling blocks interactive bursts; a high request limit can still fail a long-context job when input, output, or per-request tokens are capped. Separate prompt tokens from generated tokens, include retries and tool calls, and test the largest realistic payload. If the provider documents more than one limit window, the tightest window at your peak load is the practical ceiling. Research, experimental, and community access can also carry eligibility or fair-use constraints that cannot be modeled as a simple number.

Plan fallback without changing the rules

A fallback should preserve more than API syntax. Confirm that the substitute route supports the required modality, context length, streaming behavior, structured output, tools, and safety controls, then compare its prompt-retention and training terms. An OpenAI-compatible request shape does not make providers operationally or contractually equivalent. Decide which errors may trigger a retry, cap retry storms, and prevent an exhausted free route from silently switching to a billable model. If deterministic output matters, record the model revision and sampling settings; rotating aliases and free-model pools can change behavior even when the endpoint remains available.

Monitor the offer as a dependency

Capture the model ID, response model field, rate-limit headers, usage fields, latency, HTTP status, and any provider request identifier for each test. Watch for authorization failures, quota exhaustion, catalog removal, policy revisions, and dashboard balance changes as separate failure modes. Re-check the provider’s live catalog and governing pages on a schedule proportionate to the workload’s importance, and keep the dated sources that supported your decision. Free capacity is especially suitable for prototypes, evaluations, fallbacks, and bounded workloads when the application can tolerate change; a production dependency still needs observability, an exit path, and an owner responsible for re-verification.

Test one complete request before scaling

Start with the smallest permitted request using the exact credential, model ID, endpoint, and account type you intend to deploy. Record the HTTP status, response headers, usage fields, latency, and any dashboard balance change. Then exercise the failure path: an invalid model, an exhausted quota, or a rate-limit response should fail clearly without silently switching to a paid route. If the provider supports streaming or tool calls, validate those features separately because a free model can expose a narrower capability set than its paid counterpart. Keep a budget ceiling outside the application whenever billing is possible, and avoid sending sensitive data until the observed route matches the reviewed data agreement.
