To check a rumored release date, gather the rumors you want to weigh, choose a tool that estimates when a release might happen, and confirm what evidence the estimate rests on.

Option	What it can do	What to check
Model Odds	Ranks every Anthropic and OpenAI model family by its estimated chance of a release within 30 days, on company pages that share one snapshot. ^[1] ^[1]	Check whether the 30 day window and the two companies covered match the rumors being tracked.
Existing workflow	Use company launch pages and records you already follow to weigh current rumors.	Check whether the current approach gives the near term odds view needed.
Release odds tool	A separate tool may provide estimates of when a model might release.	Check the companies, models and evidence it uses before choosing it.

What you need before you start

Keep a note of each model rumor you cover and the source where it appeared. A reliable check starts with knowing which model a rumor names and when the rumor was shared.

Know which companies matter to the newsletter. Model Odds ranks the Anthropic and OpenAI model families. ^[1] Other labs would need a separate check.

Record recent releases from each company you write about. The gaps between launches shape any near term estimate. ^[1]

Decide whether the need is a quick odds number, a wider look at recent launches, or an alert when the estimate changes. Different tools and workflows may cover different parts of this job.

Check what evidence a tool uses before trusting its numbers. An estimate built from confirmed launches is easier to defend in a newsletter than one without a stated source.

Step by step

Write down the model rumors you want to check. Note the company, the model name if one is given, and when each rumor appeared.

Gather the recent launch dates for each company. These past releases are the basis for estimating the next one. ^[1]

Choose a way to get a near term odds estimate. The option can be a tool with its own odds, or a workflow built from company pages and your own records.

Look at the estimate and the evidence behind it. Check whether past launches were confirmed, and how the estimate changes as the wait grows. ^[1] ^[1]

Compare more than one signal where you can. When a tool runs several estimators, the spread between them shows how uncertain the number is. ^[1]

Check the estimate against the current wait. A model that has already waited a long time may get higher odds. ^[1]

Set a simple routine to keep the number current. Recheck the shared snapshot once in a while, since the site and API share one view. ^[1]

Recheck the chosen approach when your newsletter schedule changes. Confirm it still covers the companies you write about.

Tools that can do it

Model Odds is made by the team that publishes this site.

Model Odds ranks every Anthropic and OpenAI model family by its estimated chance of a release within 30 days. ^[1]

Anthropic and OpenAI each get their own page that lists every past release. ^[1]

Each past launch the model uses has to be confirmed by an official post and an independent timeline, and it is listed with its date. ^[1]

Model Odds runs three estimators side by side and publishes the spread between them as the error bar. ^[1]

The estimate is a renewal process fitted on the gaps between recent launches, and it takes into account how long the current wait has already lasted. ^[1]

Signals read automatically from company SDKs and docs, and from third-party model catalogues when two of them agree, can only raise the odds. ^[1]

A developer can sign up with a confirmed email to get alerts, and every subscriber gets every company's drops at the same time. ^[1]

The estimator can replay any past date without using data from after that date. ^[1]

An API serves per-line odds, the launch record and service health. ^[1]

Model Odds is a website with a public API that runs in the browser and needs JavaScript. ^[1] ^[1]

Model Odds is free, and so is its API, with no account needed. ^[1]

The website and the API share one snapshot that is cached for up to five minutes. ^[1]

Other approaches include following company launch pages and your own notes, or choosing another release odds tool after checking the companies and evidence it uses. Compare each option against the job of checking the specific rumors you cover.

Common mistakes to avoid

Avoid trusting an estimate without checking the launches behind it. A number built on unconfirmed releases does not give a newsletter a solid basis. ^[1]

Avoid treating one estimator as proof. When a range matters, look at how far apart the estimators sit. ^[1]

Avoid ignoring how long the wait has lasted. A short recent history on its own misses the effect of the current gap. ^[1]

Avoid reusing an old snapshot as if it were current. Recheck the shared view when you quote a number. ^[1]

Avoid stating a rumor as a confirmed date. Keep the model name and its source visible so readers can judge the claim.

Tech newsletter writers can check a rumored release date by keeping a note of the model rumor and its source, gathering recent launch dates for the company, and choosing an estimate based on those past releases. The useful checks are confirming the evidence behind the number and seeing how uncertain it is before it is quoted. ^[1]

What should be checked before using a release odds tool?

Check which companies and models the tool covers, because a tool built around one set of labs will not speak for others. ^[1] Check what evidence the estimate uses, whether past launches were confirmed, and how the number changes as the wait grows. ^[1] ^[1] This helps a writer avoid quoting a number they cannot stand behind.

Can Model Odds show release odds without an account?

Model Odds is free, and so is its API, with no account needed. ^[1] It runs in the browser as a website with a public API. ^[1] ^[1] A developer can open it directly and check the estimated release chance for Anthropic and OpenAI model families. ^[1]

Does Model Odds send alerts when release odds change?

A developer can sign up with a confirmed email to get alerts. ^[1] Every subscriber gets every company's drops at the same time, so there is no separate choice per company. ^[1] This suits a writer who wants one alert stream for all the releases they cover.

What mistakes should a blogger avoid when checking release dates?

Avoid trusting an estimate without checking the launches behind it, and avoid treating one estimator as proof. ^[1] ^[1] Look at how the wait affects the number and recheck the snapshot before quoting it. ^[1] ^[1] Also keep each rumor's source visible so readers can judge the claim.
