RightNow System Zero
RightNow is our first decision model. It belongs to a category we call System Zero.
It doesn't write text. You send it a state and your questions, and for each question it returns a decision with a probability for every option, a confidence, and a calibration version. Output is not charged, and refused calls are not charged.
RightNow AI is a YC-backed GPU research lab. This is the first checkpoint of our post-trained models, and more checkpoints will follow.
The step before thinking
Reflex Training. Decision models usually read the whole input, then answer. RightNow decides on whatever has arrived so far: stream in text, JSON, images, voice, PDF and video, and it returns a probability for every option at any moment. It is trained to hold back until the evidence is there, then commit. That is the step before thinking.
Reflex Architecture. System Zero keeps a probability for every option and updates it as each part of the input arrives.
One model, eight inputs
RightNow takes text, JSON, robot state, codebases, PDF, images, voice and video (preview).
Supported formats are PNG and JPEG for images; WAV, FLAC, MP3, OGG (Vorbis, Opus) and MP4 audio at 16 kHz; and PDF for documents.
Each call takes:
- up to 1,024 questions
- up to 38,000 state tokens
- up to 16 attachments, including up to 4 images, 1 audio file and 1 video
Text questions take 2 to 10 options or 2 to 4 levels. Media questions take 2 to 26 options or 2 to 10 levels.
Streaming decisions
You don't have to wait for the full input. Send changes as they happen: append text, update the state, or add attachments. RightNow returns versioned decisions. Every new decision carries its version, and the probability for every option updates as each part of the input arrives.
An example
- State
- The blender I ordered arrived with a cracked jar.
- Question (boolean)
- Did the item arrive damaged?
- Decision
- true

Benchmarks
Artificial Analysis Decision Index
RightNow 3.0.0 scores 63.20. This was measured by RightNow AI on the public held-out half. It is not an Artificial Analysis evaluation. The published rows come from Artificial Analysis's own evaluation, so the two are different evaluations. The chart shows positions and values only.
