Changelog
What changed lately
Every feature you can use, the day it shipped, newest first.
November 2026
Fly the map
The ship is back at the front: hold W A S D or the arrows to fly the map of every model, Shift to go faster and Space to stop, or click anywhere to fly there. Fly close to a model to see its maker, context and price, and press Enter to open it. The map now has its own place in the top bar and on the front page.
Pay less for the same work
Your account now suggests a cheaper model for the work you already send, with the saving at your own usage and today's prices, and says plainly when quality was not measured on both. When a model you use changes price, your account shows the old and new price and what it means for your month. This changelog is new too, with a feed.
One model, one row
A model's batch tier, free copy, older dated versions and aliases now list under the model itself. Pricing, the map and the Chat picker count each model once and name its copies beside it. The API still accepts every id.
A new front page
The front page now shows every model family at once. Type what you need and Autopilot picks a model to answer it, or open a family to see the models in it. One bar with one menu now sits on every page.
Keys keep their limits
Rotating a key now keeps every limit and setting it had. Every page states the same model count and writes prices the same way. A chat reply that fails now says so plainly and offers Try again.
October 2026
An API reference and a new dashboard
The API reference lists every endpoint with its fields, an example and a Try it key. The dashboard has its own page for keys, usage, logs, agents and data. Pricing is a table with a 90 day price line on each row, and Billing shows your money as a timeline.
Projects in Chat and a model picker
Chat has projects that share instructions and documents, and it can make and edit pictures in the thread. Five choices about your task now suggest three models, with the evidence for each. A converter turns an OpenAI or OpenRouter call into one for Antimatter.
More in the Nova Studio editor
The Nova Studio editor gained keyframes, speed ramps, freeze and reverse, and controls for exposure and color. An export can be a GIF, or versions for TikTok, Reels and Shorts in one press.
File search for agent runs
Hosted agent runs can search your vector stores and run several tool calls at once. The Nova Studio editor works on a phone, and a clip imported into an empty film goes straight onto the timeline.
Nova Studio opens
Nova Studio is a film editor that runs in your browser. Import your own clips, cut them on a timeline with titles and transitions, and export the film.
Everything on one page
The platform page shows everything Antimatter does as one system. Each feature that is on links to the place you use it.
Agent runs and tests you can see
A hosted agent run now shows each step on a timeline with its cost so far. Shadow tests show how often each cheaper model agreed with yours beside its cost and speed. Vector stores show their files as they are read, with a box to try a search.
Hosted agent runs
Save an agent's model, instructions and tools, then start a run with one API call and Antimatter runs the loop for you. Tools can be your own functions, MCP servers, a JavaScript sandbox or image generation. Every step is billed and held to the limits you set.
Shadow tests
Replay a sample of a key's real traffic on cheaper models and see how often they agree with the model you use today. When one is good enough, switch the key to it in one step and switch back just as easily. Replays are billed like any other request.
Vector stores and file search
OpenAI's vector store API works here. Upload files to a store and search them, or let file_search on /v1/responses answer from them.
Filter by what a model reads
Pricing can now show only the models that read audio, files or video, and the ones that make audio. Each row also tags what its model reads.
Price locks for holders
Accounts that hold $ANTI can lock one model's price for up to 30 days. You prepay credit that only that model spends, plus a premium shown before you buy. If the market price falls, you pay the lower one.
Daily receipts you can check
Each day's usage and payments are sealed into one fingerprint after the day closes. You can download a proof for a request or a receipt and check it yourself in the browser.
Every image model on one page
The images page lists every image model Chat offers, cheapest picture first. Each card shows a picture the model made from the same stated prompt, and one press opens Chat to make your own.
Easier deposits in $ANTI
The first deposit tells you how much $ANTI your amount takes, links to buy what your wallet is missing and moves on once it holds enough. Your balance also shows its size in $ANTI at today's credit price.
Pay for models in $ANTI
You add credit by paying in $ANTI on Robinhood Chain. Each payment is credited in dollars at a price measured from the market, and models are still priced in dollars.
$ANTI launched
$ANTI launched on Robinhood Chain, and you can buy it on torchpad.fun. The token page shows its contract and a link to buy it. Accounts that hold $ANTI get new models first.
Agent wallets
An agent can have its own balance and key inside your account. You fund it, cap what it spends each day and choose the models it may use.
Ask several models at once
POST /v1/ensemble sends one request to between two and eight models and returns every answer with its cost, plus one answer combined by a rule you pick. The whole request is priced and held before anything is sent. It is open to accounts that hold $ANTI.
Autopilot modes from measured tests
Autopilot gained modes for extraction and reasoning, and its code mode now picks from models that passed our own code tests. Strict JSON now works on streamed answers too.
Documents in Chat
Chat reads the documents you attach, including PDF, Word, text and CSV files. You can search your past threads and keep them in folders. The site installs as an app, and the whitepaper comes as a PDF.
Pricing for every model
The pricing page lists every model with the provider's published price beside what we bill. The cheapest page ranks the models that cost least for a need, such as vision or long context. You can sign in with email, Google or X.
Task modes, pictures and speech
Autopilot gained modes for code, long context, vision, tools and JSON. The API makes pictures and speech, transcribes audio, and can resume a stream after a dropped connection. You can share a saved chat as a link.
September 2026
A new look
Antimatter has a new mark, the Mirror ring, and a new look across the site. The whitepaper is now a page on the site.
The Responses and Batch APIs
POST /v1/responses speaks OpenAI's Responses format, so the Agents SDK and client.responses.create work unchanged. The Batch API runs a file of chat or embedding requests through /v1/files and /v1/batches.
