AI models
Context window calculator
Budget system prompts, history, retrieval, and output against sourced model constraints.
Open toolFree · private by design
Make the constraint actionable.
Deterministic tools powered by the same sourced observations as the reference pages. No account, upload, or server-side input storage.
Files & payloads
Upload limit checker
Check a file or payload against product-specific size and token ceilings.
Open toolAPI capacity
API rate limit calculator
Convert workload shape into required RPM and TPM with safety headroom.
Open toolRuntime fit
Serverless timeout checker
Compare expected duration with current function and automation ceilings.
Open toolTroubleshooting
Error decoder
Match redacted messages and identifiers to reviewed diagnoses and fixes.
Open toolChoose the tool by the failing constraint
Use the context calculator when the combined prompt, history, retrieval, tools, and expected output may exceed a model budget. Use the upload checker when bytes, encoding, extracted tokens, or an intermediate gateway may reject a file. Use the rate calculator for sustained requests and token throughput, and the timeout checker for work that could outlive a function, workflow, client, or gateway deadline.
The error decoder is the starting point when you already have a stable status code or identifier. It maps reviewed messages to diagnostic pages without sending the pasted text to an external model. Redact secrets and customer data before using any diagnostic workflow.
From estimate to production decision
- Start with representative measured inputs rather than a best-case example.
- Read the result together with its assumptions and every linked first-party source.
- Confirm the exact account, plan, model, runtime, region, endpoint, and response headers in the live environment.
- Keep operational headroom and test failure behavior at, below, and above the expected boundary.
Transparent inputs
The assumptions are part of the answer.
Every tool displays its scope, source, and verification date. Results are planning aids—not a substitute for checking the active plan, account, region, model, or response headers.
