”Mavericks AI News,” one of Japan’s largest newsletters with 80,000 subscribers

Mavericks, Inc., a developer of advanced AI products, is a Japanese startup that offers the generative AI product “NoLang.” Within one year of its release, NoLang passed 150,000 registered users and has been adopted by more than 60 corporate customers. Mavericks is an unusual case in Japan: a product-out AI startup that runs its own products every day at the front line of AI-driven development.

“Mavericks AI News” is an email newsletter delivered every Monday. In a generative AI industry that changes extremely fast, it selects the information that matters most, seen through the eyes of a team that keeps up with the front line of product development. Registering an email address is all it takes to subscribe for free each week.

The newsletter goes beyond introducing technology. It selects only substantive, practical information so that readers with no prior AI knowledge can picture concretely how to apply it from the next day, and adds original commentary grounded in specialist knowledge of AI product development. That practical, reliable approach has pushed the average open rate of “Mavericks AI News” above 40 percent. This is far higher than the average open rate for newsletters in the technology and communications sector (20.33 percent) or the average for newsletters in Japan (31.75 percent)¹, making it one of the leading newsletters in the country. With more than 80,000 subscribers, it is also among the largest in Japan, and it is the AI newsletter Mavericks recommends most to busy business people who want to keep up with generative AI.

Inquiries sent through “Mavericks AI News” are also welcome. Mavericks responds directly with proposals covering deployment support for “NoLang,” proof-of-concept projects, AI training programs, and system development tailored to a company’s own challenges, drawing on its position at the front line of AI development.

Highlights from this week’s issue (delivered November 17)

Here is a brief look at the topics covered in the latest issue, delivered on November 17.

Feature 1: Google DeepMind announces “SIMA 2,” an AI agent that plays video games and moves through 3D worlds

Describing the work as “an important step toward AGI” reflects confidence in the research results. On November 13 local time, Google DeepMind announced “SIMA 2,” a general-purpose AI agent that plays video games the way a person does. The agent uses a mouse and keyboard to carry out in-game tasks such as “enter the small cave and mine coal.”

The issue explains the latest developments in “embodied AI” aimed at general-purpose robots that operate in the real world, including the performance gains from using Gemini 2.5 Flash-lite and the agent’s “self-improvement” mechanism.

Feature 2: ChatGPT’s “group chats” feature is released, letting the AI join a conversation like another participant

Chat AI services such as ChatGPT are becoming familiar to many people in Japan, to the point that the nickname “Chappy” was nominated for the country’s buzzword of the year. OpenAI appears to want to accelerate that trend further. On November 13 local time, the company released the “group chats” feature in ChatGPT.

The issue examines concrete use cases for this feature, which lets people bring ChatGPT into a conversation much like a LINE group chat, along with impressions from actual use and what OpenAI is aiming at as it works toward AGI.

Feature 3: Will Disney+ let users generate AI content?

At The Walt Disney Company’s earnings call for shareholders, CEO Bob Iger revealed a significant strategy for Disney+. He indicated a plan to introduce a feature that would let users generate and share Disney-themed content with AI. He specifically mentioned that generating and consuming short videos might become possible, which would be a historic turning point if realized.

The issue reports on the potential for an “official AI platform” from a company that has taken a strict stance on copyright protection, and on the new relationship between AI and copyright as seen through examples from the music industry.

What comes next

As a product-out generative AI startup, Mavericks, Inc. regards returning the knowledge gained from its own advanced product development to society as an important part of its mission. Through “Mavericks AI News,” the company will continue to deliver reliable, practical information to every business person, developer, and digital transformation lead working to open up the AI era.
