Bottom line: test selectively, do not treat all channels as equal
GPT-5.5 and Claude 4.7 are becoming high-demand models, but official subscriptions and direct API usage are still expensive for students, indie makers, and light users. A few “free GPT-5.5 / Claude 4.7 trial” channels are now circulating in Chinese AI communities, especially FreeModel, Kiro, and Code Relay.
They are not the same type of offer.
| Channel | Claimed value | Card required | Risk level | Recommendation |
| --- | ---: | ---: | ---: | --- |
| FreeModel | 1-month Pro / about $66 weekly GPT-5.5-equivalent credits | No | Medium | Low-friction test |
| Kiro | $20 first-month credit / Claude 4.7-class capability | Yes | Medium | Test only if you manage renewal risk |
| Code Relay | $10 base credits plus invite rewards | No | High | Tiny non-sensitive tests only |
Our recommendation: FreeModel and Kiro are worth testing as free trial channels. Code Relay should be treated as a high-risk relay case, not a channel to promote with multi-account or anti-abuse tactics.
FreeModel: lower-friction GPT-5.5 testing
FreeModel is reported to give new users a 1-month Pro trial with around $66/week of GPT-5.5-equivalent usage. Its biggest advantage is that it does not require a credit card, which makes it friendlier for students and light users.
Good use cases
- Trying GPT-5.5-style general chat
- Testing prompt workflows and agent tasks
- Non-sensitive summarization, writing, translation, or ideation
- Deciding whether a paid official subscription is worth it
- Sign in with Google or GitHub
- Use a low-balance secondary card or virtual card, not your primary card
- Cancel auto-renewal on the same day after activation
- Save a screenshot of the cancellation state
- Do not put company secrets, client data, or unreleased code into the service
- Company code or unreleased product code
- Contracts, finance documents, customer data
- Passwords, API keys, database credentials
- ID information, phone numbers, private chats
- Anything you would not hand to an unknown server operator
- FreeModel: worth testing, but verify model authenticity and quota behavior.
- Kiro: worth testing for Claude-style writing and coding, but use a secondary card and cancel renewal.
- Code Relay: document as a risk case; do not use it as a primary recommendation.
What to verify before relying on it
Do not rely only on social posts. After signup, verify the actual dashboard:
1. Does the model list really show GPT-5.5?
2. Does the weekly quota refresh as claimed?
3. Are there rate limits, context limits, or task limits?
4. Does the account downgrade after the trial instead of charging you?
5. Can you export important conversations?
Run a small 200-500 word task first, then check model output quality and quota deduction.
Kiro: useful Claude 4.7 trial, but manage billing risk
Kiro is reported to let new users select a $20 plan that is fully covered by a first-month credit. The value is access to Claude 4.7-class capabilities for long-form writing, coding assistance, deep analysis, and multi-step reasoning.
The important difference from FreeModel: Kiro requires a card.
Safer testing checklist
If you already know how to manage card trials, Kiro is worth testing. If you are not comfortable with renewal risk, skip it.
Code Relay: high-risk relay, not a primary recommendation
Code Relay is attractive because it may expose GPT-5.5 and Claude 4.7-style models behind one relay. The shared post mentions $10 base credits and invite rewards.
The risk is also clear: this is a third-party API relay / aggregator, not an official OpenAI, Anthropic, or model-provider endpoint. Your prompts, context, files, and API requests can pass through a third-party server.
Do not send these through a relay
yangmao.ai does not recommend multi-account abuse, device switching, network switching, or other tactics to bypass platform rules. If you test Code Relay at all, use it only for one-off, non-sensitive, low-value prompts.
Which one should you choose?
If you want GPT-5.5 without a card
Start with FreeModel. It has the lowest friction and is enough to decide whether the new model is useful for your workflow.
If you want Claude 4.7 for writing and coding
Try Kiro only if you can manage billing risk. Use a secondary card and cancel auto-renewal immediately.
If you want one API relay for multiple models
You can inspect Code Relay, but do not use it for production or sensitive data. For production, prefer official APIs, reputable cloud providers, or a self-hosted relay you control.
What are free trial channels actually good for?
They are useful for:
1. Tasting new models before paying.
2. Validating prompts and workflows with real tasks.
3. Reducing experimentation cost before a subscription or paid API commitment.
They are not good for:
1. Production workloads because rules and quotas change quickly.
2. Sensitive data because third-party security boundaries are unclear.
3. Long-term arbitrage because free rules can be changed or accounts can be limited.
Final recommendation
If you only want to try the new models, run 3-5 real but non-sensitive tasks. If AI is already part of your daily workflow, long-term stability is more important than one-time free credits.
