Fit by requirement
Cloud platform
Your engineers need control over model choice, deployment and application behavior.
StayCharted
Your task is assigning categories from reviewed examples, with files, reports and review in one application.
Before choosing
For a classification dataset, convert your OpenAI JSONL conversations into a table with the input text and approved category. Preserve important context, remove evaluation leakage and keep a separate test set. Upload the table; this is not an import of OpenAI model weights or an automatic conversion of every conversation format.

StayCharted plans and workflow
Free covers text and includes up to one AI Classifier Model. Essentials is $49/month and Business is $99/month per workspace. Pictures require Vision: +$49/month on Essentials or +$99/month on Business. Dedicated AI Models require Business. Prices are USD.
StayCharted trains and runs its own models, or uses your company’s own AI for text classification. With the Your AI Models add-on ($49/month on Essentials, $99 on Business), it uses your AI on Amazon Bedrock, Microsoft Foundry, Google Cloud, OpenAI or Anthropic, gives it your categories and most similar past examples, and tests it on rows it hasn’t seen. On Business, Dedicated AI Models can also be trained in your own Amazon Bedrock; the trained model stays in your AWS account. Your own AI options
- Every training run reports accuracy on examples not used to train the model, overall and by category. Answers include confidence.
- Data-quality checks and personal-information masking before text training are available on every plan.
- On Essentials and Business, answers below your review cutoff, from files, Google Sheets, the REST API (including Zapier, Make, Power Automate and ServiceNow) and AI assistants, wait in one Review Queue; reviewed answers go into the next version’s training. Grouping unlabeled examples is also included; pictures require Vision.
- Picture checks flag near-duplicates and potentially mislabeled examples. Location metadata is stripped from the copies used by the model; original uploads are retained unchanged until deletion.
StayCharted is a hosted service: there’s no on-premises version, and it can’t import models trained elsewhere. A Builder can download a trained Dedicated AI Model (its adapter, which needs the exact base model and your own inference software), an AI Classifier Model or an AI Image Classifier Model from the model’s Manage tab. A Classifier Model runs only inside StayCharted, and a model trained in your own Amazon Bedrock is already in your AWS account.

Common questions
Will my fine-tuned OpenAI model stop working?
January 6, 2027 is the cutoff for new jobs, not a universal inference shutdown. Inference ends when the underlying base model is deprecated. Check its specific retirement date.
Can I still fine-tune GPT models?
Microsoft Foundry offers fine-tuning for supported models. Availability differs by model, region and deployment type; OpenAI’s self-serve timeline does not describe every Azure offering.
Do I need a GPU or a data scientist?
Not for StayCharted’s hosted classifier workflow. Upload labeled rows, inspect the test results and publish the version you choose. Your own cloud deployment may require technical setup.
