Facts about deprecations.info come from the public pages in the source list. Checked October 20, 2026. Publisher: SunsetDiff.
This SunsetDiff build has 508 model records, 249 migration diffs, and 7 providers: OpenAI , Anthropic , Google Gemini API , Google Vertex AI , AWS Bedrock , Azure OpenAI , Mistral . Dataset. API docs. All comparisons.
deprecations.info's homepage, fetched on October 20, 2026, calls itself AI Deprecations Feeds. It says it tracks deprecations from OpenAI, Anthropic, Google AI/Gemini, Google Vertex AI, AWS Bedrock, Cohere, Groq, xAI, and Azure, as a JSON API, a JSON Feed, and RSS. It says a model shows up when the provider announces a shutdown.
The homepage says that when a provider publishes different dates by region, the feed keeps one row per model id and uses the earliest published deprecation date and the earliest shutdown date. It links the GitHub repo deprecations/deprecations-rss and shows how to follow the RSS URL in Feedly, an email-from-RSS service, or Slack.
https://deprecations.info/v1/feed.json, fetched the same day, is JSON Feed 1.1. The title is AI Model Deprecations. The author name in the file is deprecations.info. Each item has id, url, title, content_text, date_published, tags, and a _deprecation object with provider, model_id, shutdown_date, deprecation_date, announcement_date, replacement_models, first_observed, and last_observed. The first items are OpenAI model ids whose url is an OpenAI deprecations anchor. https://deprecations.info/v1/providers.json lists those nine providers and the official URL for each.
| Topic | deprecations.info | SunsetDiff |
|---|---|---|
| Shape of the data | A feed item per announcement: model id, deprecation date, shutdown date, replacement model ids, first and last observed days, and the provider URL. | When both models are in the dataset, a migration page shows input, output, and cached price per 1M tokens, an example monthly cost, context window, max output, capability fields that differ, API changes with a source link, before/after code in Python, TypeScript, and curl, and a checklist. Empty cells say Not published. Full records also keep status, shutdown_date_kind, and specs. |
| Providers on the feed | Nine: OpenAI, Anthropic, Google, Google Vertex, AWS Bedrock, Cohere, Groq, xAI, and Azure. | The providers in this build are listed at the top of this page. |
| Regional dates | The homepage says regional dates collapse to one row, using the earliest published dates. | Bedrock rows can keep region_or_platform_notes when the official page limits the date to listed regions. |
| Other files | The homepage documents /v1/feed.json, /v1/feed.xml, and /v1/providers.json. | Static files, no API key: /data/models.json, /data/deprecations.csv, /data/changelog.json, /dataset/sunsetdiff.json, /dataset/sunsetdiff.csv, /api/v1/, /feed.xml, and /deadlines.ics.
