gemini-omni-1.1-flash Google · Gemini Omni 1.1 Flash · video Google's named replacement for every retiring Veo 3.1 endpoint and for gemini-omni-flash-preview. Video output is billed per token at $17.50 per million, which Google converts at 5,792 tokens per second of 720p video — an effective $0.1014/sec, against Veo 3.1's $0.40, Fast's $0.10 and Lite's $0.05. No token rate is published for 360p, 1080p or 4K even though all four resolutions are documented; 1080p and 4K are upscaled rather than natively rendered. Unlike Veo it also bills input at $1.50 per million tokens, so reference images and clips uploaded for extension are a new line item. Active · no date No date announced — — Endpoint turned off

How much notice each vendor gives

The written policy next to what each vendor actually did over the last 12 months. Batched announcements count once.

Vendor Written policy Median notice given Shortest After retirement
AnthropicDeprecation page ↗ At least 60 days' notice before a publicly released model retires.Active models carry a "not sooner than" date; a firm retirement date is set only when the model is deprecated. 62 days6 announcements 60 days Requests to a retired model fail.
OpenAIDeprecation page ↗ At least 6 months for generally available models, 3 months for specialised variants (chat, Codex, deep research), as little as 2 weeks for preview models.Shutdown dates are firm once announced. 181 days16 announcements 20 days Requests fail after the shutdown date. Dedicated capacity can sometimes be bought for continued access.
Google (Gemini API)Deprecation page ↗ No minimum notice period is published. Listed shutdown dates are the earliest possible dates.Every date is an "earliest possible" date; Google says it will confirm the exact date with advance notice. — — The model is turned off and its endpoint stops responding.
xAI (SpaceXAI)Deprecation page ↗ No general minimum is published; the November 2026 Imagine retirement came with a stated 60-day notice period.Retirement dates are firm. 61 days1 announcement 61 days Retired slugs keep resolving: requests are redirected to a replacement model and billed at the replacement's rates.
Mistral AIDeprecation page ↗ 6 months for generally available models; 1 month for Labs, Public Preview and third-party models.Retirement dates are firm. 36 days10 announcements 1 days Requests to a retired model fail with a 404 error.
DeepSeekDeprecation page ↗ No notice period is published.No retirement schedule is published. — — Legacy model names keep working and are served, and billed, as the current model.

Notice is counted from the date the vendor announced the deprecation to the shutdown date. Google publishes earliest-possible dates without announcement dates, so no notice figure can be computed for it.

Before a retirement date: a five-step checklist

  1. Find every caller. Export usage by API key and model from the vendor console (Anthropic: Usage → Export; OpenAI: the usage dashboard grouped by model). Background jobs and forgotten prototypes are where retired IDs hide.
  2. Pin a dated snapshot, not an alias. Aliases such as gpt-4 or claude-haiku-4-5 move or vanish with their snapshot. A dated ID tells you exactly which retirement applies to you.
  3. Re-price the replacement on your own text. Replacements often use a different tokenizer: Anthropic's newer models count about 30% more tokens for the same input. Run your real workload through the API cost calculator before you assume the new model is cheaper.
  4. Run your evals, then check the breaking changes. Newer models drop parameters (Anthropic now rejects temperature on 4.7 and later) and change defaults such as reasoning effort. Read the vendor's migration guide, not just the model card.
  5. Check the platform you actually buy through. Amazon Bedrock, Google Cloud and Azure set their own retirement dates for the same models, and they can differ from the first-party API by weeks.

Frequently asked questions

When is GPT-4 being retired from the OpenAI API?

OpenAI shuts down gpt-4-0613, along with the gpt-4 alias and its completions variants, on October 23, 2026, 184 days after announcing it. The same date covers gpt-4o-2024-05-13, o4-mini, o3-mini, o1, gpt-3.5-turbo-0125, gpt-4-1106-preview, gpt-4-turbo, gpt-4.1-nano, gpt-image-1, o1-pro. OpenAI names gpt-5.6-sol as the substitute for GPT-4. The gpt-4o alias itself is not on the list; only the gpt-4o-2024-05-13 snapshot is.

When will Claude Sonnet 4.5 be retired?

Anthropic retires claude-sonnet-4-5-20250929 on the Claude API on November 30, 2026, 61 days after the notice it sent on September 30, 2026, and recommends claude-sonnet-5-5 as the replacement. Sonnet 5.5 uses Anthropic's newer tokenizer, which counts roughly 30% more tokens for the same text, so its lower list price is a smaller saving than it looks. Amazon Bedrock and Google Cloud set their own retirement dates.

Is Gemini 2.5 Pro deprecated?

No. Google lists gemini-2.5-pro with no shutdown date announced, but it now limits access to the 2.5 models to customers who have used them before and points new projects at Gemini 3.5 Flash-Lite or 3.8 Flash. Every date on Google's deprecation page is an earliest possible date rather than a firm one.

What happens to API requests after a model is retired?

It depends on the vendor. OpenAI, Anthropic and Google turn the model off and requests fail; Mistral returns a 404 error. xAI and DeepSeek keep old model names working and quietly serve them with a newer model, billed at the newer model's rates, so nothing breaks but quality and cost can change without a code change.

How much notice do AI companies give before retiring a model?

Written policies range from none at all to six months. OpenAI promises at least 6 months for generally available models (3 for specialised variants, as little as 2 weeks for previews). Mistral promises 6 months for generally available models and 1 month for previews and third-party models. Anthropic promises at least 60 days. Over the last 12 months Anthropic's notices have run a median of 62 days. OpenAI's have run a median of 181 days. Google publishes earliest-possible dates rather than a notice period.

Which AI models are being retired next?

The next announced shutdowns are October 22, 2026 (Google: veo-3.1-generate-preview, gemini-omni-flash-preview, veo-3.1-fast-generate-preview and 1 more); October 23, 2026 (OpenAI: gpt-4-0613, gpt-4o-2024-05-13, o4-mini and 13 more); October 29, 2026 (Google: gemini-3.1-flash-image). The table on this page lists every announced date, with the replacement each vendor recommends.
