GPT-3.5 Turbo (0301) (OpenAI)

Retired

Yes — GPT-3.5 Turbo (0301) is retired. OpenAI deprecated it on June 13, 2023 and shut it down on September 13, 2024; API requests to it now fail. The recommended replacement is GPT-3.5 Turbo.

The launch snapshot of GPT-3.5 Turbo, from March 2023 — the model that made chat APIs cheap and kicked off the current wave of applications. It was deprecated three months after release and took eighteen months to actually go.

Now deprecated in turn. Anything still pinned to a 2023 snapshot should go straight to a current model rather than to the pointer.

What parameters gpt-3.5-turbo accepts on modelparams.dev

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. 

- "model": "gpt-3.5-turbo-0301"
+ "model": "gpt-3.5-turbo"

Where the migration path ends

The recommended successor has itself been replaced. Following the chain to a model that is still active today:

  1. gpt-3.5-turbo-0301
  2. gpt-3.5-turbo Deprecated
  3. gpt-5.6-terra Active

How to use this site

# 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.
