Introduction
Everyone knows that the MAX plan lets you "use more."
That's not what I want to know. What actually changes with MAX? When I looked into it, I found that some features often assumed to be "MAX-exclusive" were not, while other differences were not widely known.
I have organized the information while verifying with official sources.
Default model is Opus
With Pro, the default model is Sonnet. With MAX, Opus 4.6 is the default.
It might seem trivial, but it's a big deal. With Pro, there's the hassle of switching to Opus every time, and you tend to compromise by thinking, "Sonnet is probably fine..." out of concern for your usage limits. With MAX, it starts with Opus and you can keep using it that way.
Reference: What is the Max plan?
1M context window at no extra cost
Opus 4.6 supports a context window of up to 1 million tokens (1M). However, it is treated differently depending on the plan.
| Plan | 1M context for Opus |
|---|---|
| MAX / Team / Enterprise | Included in subscription |
| Pro | Requires enabling extra usage (additional charges) |
With MAX, Opus is automatically upgraded to 1M context without any configuration. With Pro, to use 1M, you must enable "extra usage" and accept the additional charges.
What changes with 1 million tokens:
- You can grasp dependencies between files in large codebases at once
- Previous context is less likely to disappear in long sessions
- Frequency of
/compactis reduced
Priority access to new features — This is surprisingly huge
It is officially stated: New features and models are often provided to MAX first.
Let's list which features were actually MAX-first:
| Feature | Description | MAX-First |
|---|---|---|
Remote Control (/rc) |
Intensive development from smartphone using Claude Code | Feb 2026 onwards. Not yet available for Pro (as of Mar 2026) |
| Cowork | Delegate tasks to Claude via macOS app | Jan 2026 onwards. Pro later |
| Dispatch | Send tasks to Cowork from smartphone | Mar 2026 onwards. Pro a few days later |
| Computer Use | Claude operates the PC directly | Mar 2026 onwards. Pro 2 days later |
| Memory | Automatically retain conversation memory | Oct 2025 onwards. Pro a few days later |
A pattern emerges. Almost all agent-related new features are MAX-first. The gap can be a few days, or in the case of /rc, more than a month and still not available for Pro.
For those who want to experience new features quickly, MAX is essentially in the position of a "paid beta tester." I use /rc quite often, so it's a relief that it's available for MAX first.
Features often thought to be MAX-exclusive, but actually are not
These are easy to misunderstand, so let's clarify. The following features can also be used with Pro.
Effort MAX (Maximum thinking depth)
The maximum value of the Effort setting, "MAX," is tied to the model, not the plan. As long as you are in an environment where you can use Opus 4.6, you can select Effort MAX with both Pro and MAX.
However, in reality, Effort MAX consumes a lot of tokens, so you will reach the limit quickly with Pro usage. With MAX, you can run it on MAX constantly without worry. As a feature, it is available on Pro, but practically, it's tough without the usage allowance of MAX.

Sub-agents
A feature where Claude Code launches sub-agents (clones) to conduct parallel research. This also has no plan restrictions. Anyone in an environment where Claude Code can be used can use it.

/batch
A feature for parallel processing large-scale changes. This is also a built-in skill available to all Claude Code users.

Research (Research mode)
A feature where Claude autonomously searches the web for investigations. It is available on all paid plans: Pro, MAX, Team, and Enterprise. The Research feature itself is not enhanced just because you have MAX. However, Research consumes a lot of tokens, so it will strain your usage limit on Pro.

So what is the real value of MAX?
Looking only at the features, there are surprisingly few MAX-exclusive ones. To summarize:
| Pro | MAX | |
|---|---|---|
| Default model | Sonnet | Opus |
| Opus 1M context | Additional charge required | Included in subscription |
| Priority access to new features | Later | Use first |
| Effort MAX | Available but hits limit quickly | Run on MAX constantly |
| Sub-agents | Available but hits limit quickly | Use without worry |
| Research | Available but strains usage | Use without worry |
A pattern is visible. There are many features that can be used with Pro. But with Pro's usage limit, you cannot fully utilize those features.
Effort MAX, sub-agents, and Research all consume tokens the more you use them. Pro creates a dilemma where "the feature exists, but using it hits the limit." MAX removes that limiter.
You might think this just brings us back to "you can use more." But "increasing the amount" and "fully utilizing the feature" are different. The value of MAX lies in the latter.
Summary
When I looked into it, there were fewer MAX-exclusive features than I thought. The real value lies in "using existing features without a limiter."
Opus is the default. 1M context at no extra cost. Experience new features first. And you can use Effort, sub-agents, and Research to your heart's content without worrying about usage limits.
$100 a month is not cheap. But which is more valuable: paying $20 and not being able to use the features fully, or paying $100 and using them fully? For me, it was the latter.
