AI Model Releases by Day of Week

Run the AI Model Releases by Day of Week MicroSim Fullscreen

About This MicroSim

This bar chart tallies all 249 tracked AI model releases by the day of the week they shipped on, replicating the "Releases by Day of Week" chart from AI Release Tracker.

The pattern is a familiar one to anyone who works in software: releases cluster heavily on weekdays (Tuesday and Thursday lead, with 61 and 62 releases respectively) and drop off sharply on weekends (only 4 releases combined across Saturday and Sunday). It's a small but concrete illustration that even frontier AI labs ship on ordinary engineering-team schedules.

How to Use

Hover over any bar to see its exact count and share of all tracked releases. Weekend bars are shown in purple.

Updating the Data

Chart values live in a dataset shared by six MicroSims: ../ai-release-data/data.json. This chart reads the dayOfWeek array. See ../ai-release-data/README.md for the full schema.

These MicroSims share the same dataset:

Lesson Plan

Grade Level

Adult professional / executive education (organizational AI-tracking course)

Duration

5 minutes

Prerequisites

None — a light, engaging warm-up chart.

Activities

  1. Exploration (2 min): Have learners guess which day has the most releases before revealing the chart.
  2. Guided Discussion (3 min): Discuss what the weekday-heavy pattern suggests about how AI labs operate (deliberate release scheduling, normal engineering cadence, avoiding weekend on-call incidents).

Assessment

Learners should be able to state the day with the most releases and offer one plausible organizational reason for the weekday/weekend pattern.
