GPT-5 Pro (OpenAI)

Deprecated Shuts down in 134 days

Yes — OpenAI deprecated GPT-5 Pro on June 11, 2026 and shuts it down on December 11, 2026 (in 134 days). The recommended replacement is GPT-5.6 Sol.

The extended-compute tier of GPT-5, which spent far longer per request to buy accuracy on hard problems. It shipped two months after the base model and was deprecated on the same date, which is the useful lesson: a Pro tier does not get a longer life than the generation it belongs to.

The facts

What to use instead

OpenAI GPT-5.6 Sol gpt-5.6-sol Provider-recommended Active

Sol at a high reasoning_effort is the closest equivalent. There is no separate "-pro" id in the 5.6 generation — the compute dial moved into the request instead of the model name.

Change the id

In most cases the migration is one string. Check the parameter differences before you ship — newer models drop older sampling knobs more often than they add them.

Frequently asked questions

When will OpenAI GPT-5 Pro shut down?
OpenAI GPT-5 Pro is scheduled to shut down on December 11, 2026, in 134 days.
What replaces OpenAI GPT-5 Pro?
OpenAI recommends GPT-5.6 Sol (`gpt-5.6-sol`) as the replacement for OpenAI GPT-5 Pro. Sol at a high reasoning_effort is the closest equivalent. There is no separate "-pro" id in the 5.6 generation — the compute dial moved into the request instead of the model name.
Is OpenAI GPT-5 Pro still available?
Yes, for now. OpenAI GPT-5 Pro is deprecated but still answers requests until December 11, 2026. Deprecated models get no further updates and are the first to lose capacity.
How do I migrate from OpenAI GPT-5 Pro to gpt-5.6-sol?
Swap the model id in your API call: replace "gpt-5-pro" with "gpt-5.6-sol". Sol at a high reasoning_effort is the closest equivalent. There is no separate "-pro" id in the 5.6 generation — the compute dial moved into the request instead of the model name.
Does this apply to gpt-5-pro-2025-10-06 too?
Yes. OpenAI GPT-5 Pro is also published as `gpt-5-pro-2025-10-06`; that id shares the same lifecycle dates as `gpt-5-pro`.

# How to use modeldeprecations.dev

[modeldeprecations.dev](https://modeldeprecations.dev) answers one question per model: is it deprecated,
when does it shut down, and what replaces it. Every date on the site is cited to the
provider's own documentation, with the date we last checked it.

Three lifecycle states are used, matching the providers' own vocabulary:

- **active** — still supported, no deprecation announced.
- **deprecated** — the provider has announced it is going away. It still answers requests.
- **retired** — API access is gone. Requests fail.

A model can be active *and* carry a shutdown date: Anthropic publishes a
"not sooner than" date and Google publishes an earliest shutdown date for models
that are current and fully supported. Those are reported as scheduled shutdowns,
not deprecations, because that is what the provider actually committed to.

## Check one model

```bash
curl https://modeldeprecations.dev/api/v1/models/openai/gpt-4-32k.json
```

Or fetch the page as Markdown, which includes the answer, the dates and the sources:

```bash
curl https://modeldeprecations.dev/openai/gpt-4-32k.md
```

## Full catalog

```bash
curl https://modeldeprecations.dev/api/v1/models.json
```

Ids are `provider/model`. Dated snapshots (`gpt-4-32k-0613`) are listed as aliases of
their canonical entry rather than as separate records.

Each entry carries `computed_status`, the lifecycle state recomputed against the build
date — so a model whose shutdown has passed reads `retired` without anyone editing data.

## Badges

A shields.io endpoint per model, for READMEs that should go red when a model dies:

## Contribute

Data lives in YAML under `models/{provider}/{model}.yaml` in the
[GitHub repo](https://github.com/mnfst/modeldeprecations.dev). Every lifecycle date needs a source URL; CI rejects a
date without one. Open a PR.
