01 · principles

Every choice explains the system.

The current website supplies the restraint. The native mood board supplies the living model language. The system keeps both.

01

Evidence earns attention.

Show the trace, comparison, result, or system state.

02

Color has a job.

Color identifies an actor, operation, or outcome.

03

Motion explains work.

Breath, orbit, transfer, and promotion carry meaning.

04

Structure stays quiet.

Hairlines and spacing create hierarchy before panels do.

05

Complexity stays inspectable.

Name every actor, threshold, and result.

02 · model color

A small palette with exact jobs.

cyan
#67E8F9
Parallel work and trace flow.

An earned result.

03 · visual grammar

Shape identifies the actor.

Open models expose a circular core. Closed models seal their structure into tiles. Both use the same state and motion system.

04 · operations

Mint and cyan carry the work.

These patterns come from 04b and 04e. RLM fans one mind into smaller quests. Training loops return only the evidence that improves the policy.

05 · typography

Mono for structure. Sans for reading.

The current website's mono register stays. Product prose gets a companion built for sustained reading.

05A
Test. Learn.
Deploy. Repeat.

IBM Plex Mono carries identity, controls, model labels, data, and short declarative headlines.

05B
Production traces show which model actually works for your workload.

IBM Plex Sans carries explanation, documentation, and dense product prose.

06 · components

VOICE
Use the data you have. Build the model you need.

Direct

Make one clear point per statement. Do not repeat it in clauses.

Earned confidence

Use results and examples that a reader can inspect.

Data-first

Name the metric, baseline, evaluation set, and result.

Unapologetic

Challenge the default. Do not attack the people who chose it.

weak

Unlock powerful optimization capabilities across your AI ecosystem.

understudy

Compare every model on your workload. Deploy the one that wins.
