# Claude Max vs API

Claude Max costs $100/month flat ($200 for the 5x plan). If you keep hitting the limit on Pro and wonder whether Max fixes it — or whether there's a cheaper way out — the answer comes down to how much you actually use. On RunAPI, $100 buys roughly 6.7 million Sonnet 4.6 output tokens with no usage cap.

## Claude Max vale a pena, ou a API é mais barata?

Claude Max wins for one heavy individual user who lives in Claude Code all day and consistently hits limits on the $20 plan. The API wins for teams, CI pipelines, multi-model setups, and anyone who wants to stop worrying about 5-hour windows and 50-session monthly caps. The break-even on Sonnet 4.6 through RunAPI sits near 6.7M output tokens per month.

- **Claude Max**: $100/mo flat for high Claude Code limits. $200/mo for the 5x plan. No API access, subject to 5-hour usage windows and a 50-session monthly cap.
- **API via RunAPI**: Pay per token. Sonnet 4.6 at $3/M input, $15/M output — 50% off official. No caps, no windows, no commitment.
- **Ponto de equilíbrio**: Around 6.7M Sonnet 4.6 output tokens/mo. Below that, the API costs less than $100 with no usage cap.
- **Controle de limite de saída**: Defina CLAUDE_CODE_MAX_OUTPUT_TOKENS para limitar o custo por resposta na rota de API.

## O que cada plano Claude inclui?

A Anthropic vende quatro camadas para consumidores. A tabela resume o preço, o acesso ao Claude Code e o teto de uso prático em cada uma.

| Plano | Preço | Acesso ao Claude Code | Teto de uso |
|---|---|---|---|
| Gratuito | $0 | Limitado / somente chat | Limite baixo de mensagens diárias |
| Pro | $20/mês | Sim, limites modestos | ~45 messages per 5-hour window |
| Max | $100/mês | Sim, limites altos | ~225 messages per 5-hour window, 50 sessions/mo |
| Max 5x | $200/mês | Sim, limites mais altos | ~900 messages per 5-hour window, 50 sessions/mo |

## Quando a API supera o Claude Max?

A decisão é aritmética. Converta $100 em tokens pelas tarifas do RunAPI e compare com seu uso mensal real. A saída do Sonnet 4.6 custa $15/M no RunAPI, então $100 cobre cerca de 6,7 milhões de tokens de saída.

### API vence abaixo de 6,7M tokens

Se você gerar menos de ~6,7M tokens de saída do Sonnet 4.6 por mês, a API por uso custa menos que o plano Max de $100.

### Max vence acima de 6,7M tokens

Usuários intensivos diários de Claude Code que consistentemente excedem esse volume pagam menos com a assinatura fixa de $100.

### Equipes preferem a API

Max é por pessoa. Uma equipe de 5 pessoas precisa de 5 assinaturas ($500/mês); um saldo compartilhado no RunAPI não tem taxa por usuário.

### CI e automação preferem a API

Assinaturas cobrem uso interativo, não pipelines headless. A cobrança por API é o único caminho para CI, cron jobs e agentes server-side.


## Quais são os limites de uso do Claude Max?

Max is not truly unlimited — not even the $200 plan. Anthropic enforces rolling 5-hour usage windows: hit the cap and you wait, with no way to pay more to continue. The $100 plan gives roughly 5× the usage of Pro per window; the $200 plan roughly 20×. On top of that, Max is capped at 50 sessions per month. Accidentally send a single message right after a session ends and you burn a new session. None of these constraints exist on the API.

### Rolling 5-hour windows

Usage resets on a rolling 5-hour schedule starting from your first message — the clock runs even when you're idle. Hit the cap and you wait for the window to reset.

### Limitação de Opus

Opus access is more restricted than Sonnet on Max. Sustained Opus use drains your allowance faster — you can hit the limit faster than you expect.

### Sem opção de excedente

When you hit the Max ceiling, there's no pay-more button — you wait. The $100 plan caps you at 50 sessions per month; if you chat throughout the day, those sessions burn faster than expected.

### Controle de tokens de saída

Na API, CLAUDE_CODE_MAX_OUTPUT_TOKENS limita o comprimento por resposta, dando controle direto sobre o custo e evitando gerações descontroladas.


## O que a API oferece que o Max não oferece?

Beyond price at low volume, the API removes the walls that stop you mid-task. No 5-hour windows, no session counting, no waiting 4 hours for a reset. These matter most for teams and automated workloads.

### Sem limites de uso

Pay-as-you-go means you never hit a wall mid-task. No 5-hour windows, no 50-session monthly cap — you pay for what you send and nothing stops you.

### Acesso a múltiplos modelos

Use Opus, Sonnet, and Haiku — plus GPT and Gemini — on one key. Max is Claude-only and Claude Code-only.

### Pronto para equipes e CI

Um único saldo cobre toda a equipe e cada pipeline automatizado, sem cálculos de assinatura por usuário.

### 50% de desconto nas tarifas oficiais

O RunAPI espelha os preços do Claude à metade da tarifa publicada, baixando ainda mais o ponto de equilíbrio em favor da API.

## Perguntas Frequentes sobre Claude Max vs API

### Claude Max vale a pena?

For one heavy user who runs Claude Code all day and consistently hits limits on the $20 plan, Max can be worth it. Below ~6.7M Sonnet output tokens a month, or for teams and automation, pay-per-token API access through RunAPI costs less and never cuts you off mid-task.

### Quais são os limites de uso do plano Claude Max?

Max enforces rolling 5-hour usage windows — the clock starts on your first message and runs even when you're idle. Hit the cap and you wait for the window to reset; there's no pay-more button. The API has no such wall.

### Quantos tokens $100 compra na API?

At RunAPI's Sonnet 4.6 rate of $15 per million output tokens, $100 buys roughly 6.7 million output tokens. That's your practical break-even: generate fewer output tokens in a month and the API costs less than the flat $100 Max plan, with no usage cap attached.

### Claude Max inclui acesso à API?

No. Claude Max covers interactive use in Claude Code and the chat app only. It does not provide API keys for server-side calls, CI pipelines, or third-party tools. For those, you need API access such as RunAPI.

### Why did I get cut off after paying $200/month?

Yes — even the $200 plan has limits. Max $100 gives roughly 5× the usage of Pro per 5-hour window; Max $200 gives roughly 20×. But the clock still runs, sessions still count, and you can still get cut off. The API is the only path with no ceiling.

### Is there a monthly session limit on Max?

Yes. On the $100 Max plan, Anthropic caps you at 50 sessions per month — each session is a 5-hour block. If you chat sporadically throughout the day (8am, 3pm, 9pm), that burns 3 sessions. Pro's unlimited sessions can actually be a better fit for casual daily use than Max.

### Uma equipe pode compartilhar um plano Claude Max?

No. Max is a per-person subscription tied to one individual account and cannot be shared across a team. A five-person team would need five separate plans at $500 a month total. One shared RunAPI balance carries no per-seat fee and covers every member plus any CI pipeline, which is why teams generally favor the API.
