Required environment for AI image generation | Difference between cloud AI and local AI | Sugiyama Nobutsugu

Why AI image generation stops choosing the environment

When trying to incorporate AI image generation into practice、Many people stop at ``What kind of environment do I need?''。

  • Do I need a high-performance PC?
  • Is cloud alone enough?
  • Should I prepare a local environment?

If this judgment remains ambiguous、The implementation itself is not progressing。

The only important thing here is、Environmental issues are not “specs”、
How much of the production process do you control?The point is that it is a design problem.。


Why is our understanding of the environment so wrong?

Cloud or local、Eventually the image will be generated.。

Therefore、

  • Looks like you can do the same thing with either
  • Difficult to tell the difference

The state will be。

However, in practice it is clearly different.。

  • Who is in charge of the generation process?
  • How much control can you have?
  • Can you reproduce the same result?

This difference、This directly affects the stability and scale of production.。


Structure of cloud AI and local AI

First, organize the structure。


Cloud AI:Mechanism that can be completed with external processing

Typical cloud type:

  • Midjourney
  • DALL-E
  • Adobe Firefly
  • Gemini
  • ChatGPT
  • Grok et al.

Cloud AI is、All image generation processing is done on the server side。

The user、

  • Enter text or image
  • receive the generated results

Only。

In other words、
The generation mechanism is provided as a black box.です。


local AI:Mechanism to control within the PC

represent:

  • Stable Diffusion

Local AI is、

  • AI model
  • Generation settings
  • processing process

Handle everything on your PC。

This means、
An environment where generation is treated as a “process” rather than a “result”です。


Changes in practice and the market (structures created by differences in the environment)

Visual production、1The structure has changed from creating points.。

  • submit multiple ideas
  • Verify and choose
  • make only what you need

In this flow、

  • Cloud = verification
  • local = production

There has been a division of。

The difference in environment is、The production flow will be different.。


example:Differences in production flow depending on environment

For example, creating product visuals.。


When proceeding only with the cloud

  • Generate multiple patterns
  • choose a good one

The work has been put in the adult category because of the photo showing the bust of the cut.、

  • speed is fast
  • Initial quality is high

But、

  • Unable to reproduce the same composition
  • Difficult to continue operation

There is a restriction that。


When incorporating local

  • Fixed conditions
  • Generated with the same composition

The work has been put in the adult category because of the photo showing the bust of the cut.、

  • reproducible
  • Mass production possible

instead、

  • Environment construction required
  • Requires understanding of settings

becomes。


Advantages and disadvantages of cloud AI

merit

No environmental dependence

  • Regardless of PC specs
  • GPU does not need

→ Ready to implement


High initial quality

  • Consistent quality with no settings required

→ Strong in rough production


Easy to increase the number of trials

  • Instant generation

→ Suitable for verification process


Disadvantages

narrow control range

  • Difficult to fix composition
  • Unable to reproduce conditions

I can't see the internal specifications.

  • I don't know why that result

There are restrictions

  • Number of times limit
  • Not customizable

Advantages and disadvantages of local AI

merit

Wide control range

  • Conditions can be set in detail

→ Can be incorporated into the production process


reproducible

  • Can be generated under the same conditions

→ Suitable for continuous production


scalable

  • Models and settings can be changed

Disadvantages

Environment construction required

  • Setup required

hardware dependent

  • Influenced by GPU/memory performance

Highly difficult to operate

  • Requires understanding of settings

Differences in major services (understand by connecting to the environment)

Roles are different even in cloud type。


Midjourney

  • Strong against atmosphere generation
    → Directional design

DALL-E

  • Easy to follow instructions
    → Composition verification

Adobe Firefly

  • Production tool collaboration
    → Actual production connection

Stable Diffusion

  • Control/Mass production
    → Production project

Role sharing between human production and AI environment

Choosing the environment is just a matter of division of roles.。

cloud

  • rough generation
  • Tone confirmation
  • Initial verification

local

  • Conditions are fixed
  • Reproduction
  • Continued production

people

  • concept design
  • brand judgment
  • final quality

summary:The environment is determined by the production design.

The environment for AI image generation is、

  • specs
  • tool

It is not decided by。

There are three criteria。

  • Do you need control?
  • Do you need reproducibility?
  • Should it be incorporated into the production process?

Considering these three points、

  • Is the cloud enough?
  • Do you need local?

becomes clear。

Environment selection、
The design itself of the production processです。
