A Midsummer Day's UpdateAnnouncing a feast of updates to the Mercury models and to our API platform.Jul 20, 2025Product

I have had a most rare vision . . . of new features that were bidden.

And today we lay before thee, gifts of Mercury unhidden.

• The context window of Mercury and Mercury Coder has been increased to 128K tokens.

• Mercury and Mercury Coder now support tool calling and structured output.

• Mercury and Mercury Coder now support non-zero temperature.

• There is now a free tier of API access. All users receive 10 million tokens when they create their account.

• Users can now set billing limits. We will send an email alert when a user reaches 80% of their limit and will block requests when a user hits their limit. The limit can be set on the Billing Page on the platform.

• Users can now opt out of allowing their data to be used for model training. The toggle is available on the Account Settings Page.

Now to bed we go — but brief. Let slumber rock,

then swift relief. For updates new shall come — 'tis our belief.
