Keep your plan and add the others in Reason
Open Reason on the web or the Mac app
Sign in at reasonmachines.com, or download the Reason app for macOS from reasonmachines.com/download. Both open the same Sessions. Sending work to Reason needs a Pro or Max plan.
Connect the plans you already pay for
In Settings › Models, under Subscriptions, connect ChatGPT (Plus, Pro or Business), Claude (Pro or Max), Grok (SuperGrok or X Premium+) or GitHub Copilot, and add API keys if you have them. Work on those accounts is billed by their provider, not in Reason credits.
Pick the model per task
In the composer, choose the model for each Session: a smaller model for routine fixes, a larger one for hard changes. Each Session shows the model and account it ran on.
Keep going at a limit
When the account a turn runs on hits its limit, Reason moves the turn to your other connected accounts for that provider, then to Reason credits if your workspace can pay, and says so in the conversation.
Claude Max and the alternatives
| Plan | Price | Usage and limits, from its plan page |
|---|---|---|
| Claude Max | $100 a month | 5x Pro usage every five hours and every week, shared across Claude and Claude Code |
| Claude Ultra | $200 a month | Replaced Max 20x; 10x Pro's weekly usage; no five-hour limit once verified |
| ChatGPT Pro | $100, $200 or $500 a month | Codex everywhere; no five-hour limit today, weekly limits may apply; Ultrafast on Pro 500 only |
| GitHub Copilot Max | $100 a month | 20,000 AI credits a month; Claude Opus and Fable models included |
| Cursor Super / Ultra | $100 / $200 a month | A weekly usage pool shared across Cursor and Grok; other vendors' models billed separately |
| Devin Max | $200 a month | Allowance refreshes daily and weekly; extra usage at API pricing |
From each vendor's plan page, checked Nov 2, 2026. Max includes $100 a month in API credits for the Claude Platform, but Anthropic says they can't be used in Claude Code or the Claude apps.
Which alternative fits
Hitting Max's five-hour limit: Ultra removes it once verified, and ChatGPT Pro has no five-hour limit today. Want Claude models without a Claude plan: Copilot Max includes Opus and Fable in Copilot's own agents. Already on Cursor or Devin: their top tiers keep you in the same tool.
Or keep Max and add a second plan from another provider, so a limit on one doesn't stop the work.
Reason: all your AI subscriptions in one coding agent
Use the subscriptions you already pay for (ChatGPT Plus/Pro/Business, Claude Pro/Max, SuperGrok or X Premium+, GitHub Copilot) or your own API keys in one coding agent. Hit your limit? Reason keeps going on your other connected accounts or Reason credits.
Reason isn't the lowest-priced agent on this page: Pro is $50 a month with 1,250 credits a week, and Max is $200 with 5,000; a credit is $0.04. Work on your own connected subscriptions or API keys is billed by that provider, not in Reason credits, so you don't pay twice for a plan you already have.
On cost: in Reason's published benchmark on GPT-6 Astra at xhigh effort, with the same tasks and graders, Reason 1.1 scored 65.1 against Codex's 62.5 on Coding Agent Index v1.5, at 22% lower cost per solved task. That's Reason's benchmark of its own harness, with the runner published to reproduce it.

Questions
What is a good alternative to Claude Max?
At the same price, ChatGPT Pro (from $100, with Codex) and GitHub Copilot Max ($100, with Claude Opus models). Within Anthropic, Ultra at $200 replaced Max 20x and has no five-hour limit once verified.
Is there an alternative to the Claude Code Max plan?
Claude Code runs on Claude plans, so Anthropic's own alternative is Ultra. Outside Anthropic, Codex on ChatGPT Pro is the closest coding agent at the same price.
Is Claude Max worth it for Claude Code?
If you hit Pro's limits regularly, Max gives 5x Pro usage every five hours and every week for $100. It still has a five-hour and a weekly limit, shared with claude.ai.
Can I use Max's API credits in Claude Code?
No. Anthropic says the monthly API credits included with Max can't be used in Claude Code or the Claude apps.
What happens in Reason when my plan hits its limit?
Hit your limit? Reason keeps going on your other connected accounts or Reason credits. The turn moves to your other connected accounts for the same provider, then to Reason credits if your workspace can pay.
Is Reason affiliated with these vendors?
No. Reason is built by Reason Machines and is not affiliated with or endorsed by Anthropic, OpenAI, GitHub, Anysphere, Google, Cognition or xAI. Prices and limits come from their own pages, linked under Sources.
