If you’re looking for a ChatGPT Pro 200 alternative because of OpenAI’s October usage cut, Haimaker is an option for coding and API work that can move to a metered model. One key gives Codex CLI and other coding agents access to a choice of models. Haimaker does not include the ChatGPT interface or the new dots agents.
That distinction matters. Someone who spends most of the day in Codex can test a different billing model without changing the coding agent. Someone who relies on ChatGPT’s Pro features needs to compare those separately.
What changes for Pro 200 on October 30?
OpenAI’s email to Pro subscribers, reproduced by a recipient says the Pro 200 price stays the same while included ChatGPT Work and Codex usage falls on October 30, 2026. For affected subscribers, the allowance moves from 20 times to 10 times the ChatGPT Plus allowance. GPT-6 Pro messages in Chat drop from 200 to 100 per week. OpenAI’s updated plan guidance confirms that eligible subscribers keep the previous allowance through October 29.
| Affected Pro 200 subscribers | Through October 29 | Starting October 30 |
|---|---|---|
| ChatGPT Work and Codex | 20× Plus | 10× Plus |
| GPT-6 Pro messages in Chat | 200 per week | 100 per week |
| Subscription price | Unchanged | Unchanged |
OpenAI also says the five-hour limit will not return, so subscribers can use their weekly allowance when they need it. Existing subscribers are being offered a one-time grant of 62,500 usage credits, which OpenAI describes as a $2,500 value. The email says those credits expire on December 31, 2026. Check your own Settings > Usage page for eligibility and balance.
The same announcement adds Pro 500, with 25 times the Plus allowance and Ultrafast token generation advertised at up to eight times the usual speed. Pro subscriptions also include dots, OpenAI’s always-on agents; according to the email, work done directly by a dot does not consume the ChatGPT usage allowance. Those additions may matter if you use the whole Pro product, even if the Codex reduction is your reason for looking elsewhere.
Which alternative fits the work you actually do?
Compare the options against a week of your own work. Haimaker charges for API usage and lets you choose models for coding agents or applications. OpenAI’s Pro tiers bundle access to its tools behind usage allowances. A direct provider API also charges for usage, but gives you one provider’s catalog.
| Option | Best fit | How usage works | What to check |
|---|---|---|---|
| Haimaker | Coding agents and apps that can use an API key | Metered model usage through one account | Model availability, token spend, agent compatibility |
| OpenAI Pro 100 | Lighter use of OpenAI’s first-party tools | Subscription allowance below Pro 200 | Whether its lower limit is enough for your week |
| OpenAI Pro 200 | People who use ChatGPT, Codex, Work, and dots together | Subscription allowance; 10× Plus for Work and Codex from October 30 | Whether the new weekly limit covers your real workload |
| OpenAI Pro 500 | Heavy use of OpenAI’s first-party tools | Subscription allowance; 25× Plus, with Ultrafast | Whether the extra capacity and speed justify the higher tier |
| Direct model APIs | Teams committed to one provider | Metered API usage with that provider | Separate keys, billing, and integrations when you add providers |
Haimaker’s model API gives developers one OpenAI-compatible endpoint for more than 200 models. You can choose a lower-cost model for routine agent steps and reserve a premium model for tasks that need it. That lets you control which requests incur premium costs, though a heavy workload can still cost more under metered billing. Measure your own token use before making a price claim.
The fit depends on where you work. For a coding agent reading files, calling tools, and generating patches, the model endpoint is a large part of the workflow. If you spend your time in ChatGPT conversations, dots, and Work, an API gateway covers much less of what you’re paying for.
TEST A CODING AGENT WITH HAIMAKER
How to try Haimaker with Codex CLI
Keep the Codex CLI interface and send its model requests through Haimaker. The connect setup writes Codex’s native provider configuration and then exits; the agent calls Haimaker’s API directly. Begin with one real project and compare the result, latency, and usage cost with your current Pro workflow before moving everything.
- Set up a Haimaker account and obtain an API key.
- Place the key in your shell environment as
HAIMAKER_API_KEY. - Execute the Codex setup command:
npx -y @haimaker/connect --codex
The command can help you choose a model. Check the current model catalog for exact model IDs and availability; don’t assume a newly announced ChatGPT model is already offered through an API. Then run a familiar Codex task and review its spend in Haimaker. The full Codex configuration guide also shows the manual config.toml route.
OpenCode setup is another path for a coding agent built around switching providers. Either tool can use the same Haimaker key, so models can be compared without opening a separate account for each provider.
Check the credit grant before changing plans
Staying during the transition may still be useful because of the one-time Pro 200 credit grant. OpenAI’s credit documentation states that these credits extend eligible ChatGPT features after included usage runs out and are not API credits. They cannot be transferred to Haimaker. OpenAI’s email assigns the grant a December 31 expiration date, so its value depends on whether it will be used by then.
OpenAI’s current Pro tier help page says new Pro 200 subscriptions are available again, but subscribers who rejoin without grandfathering receive the lower allowance. If you want to preserve the previous allowance through October 29, check your eligibility and billing settings before canceling.
For a fair comparison, record one week’s Codex tasks and the models they require. Try those tasks through Haimaker while your current Pro allowance remains active through October 29. You’ll learn whether model choice and metered billing solve your actual limit problem, while keeping the rest of your Pro decision separate.
Frequently asked questions
Is Haimaker a replacement for ChatGPT Pro?
Haimaker can replace the model access behind API-based coding agents and applications. It does not include the ChatGPT interface, dots, or the subscription’s bundled usage, so it is most useful when your work already runs through an agent or API.
Can I use OpenAI’s Pro 200 grant with Haimaker?
No. OpenAI’s one-time usage grant applies to eligible features in its own products, and OpenAI says ChatGPT usage credits are separate from API credits. A Haimaker account has its own billing.
Can I keep using Codex CLI with Haimaker?
Yes. Codex CLI supports a custom model provider, and Haimaker’s connect command can write that configuration. Requests then use your Haimaker API key and are billed as API usage rather than drawing from your ChatGPT Pro allowance.
