qwen3.6-27b-free retired: managing the daily quota on qwen3.8-27b-free
qwen/qwen3.6-27b-free was retired on 19 September 2026; this covers its successor qwen/qwen3.8-27b-free's daily usage quota and what happens once the quota is reached.
The old identifier no longer works
qwen/qwen3.6-27b-free was retired in the catalog on 19 September 2026 after being removed on the provider side; requests to this identifier now return a 410 model_retired error. Its successor, qwen/qwen3.8-27b-free, is also offered free and supports tool calling, JSON-mode output, and image input.
The one thing lost between the two identifiers is a reasoning trace the old row returned; the successor does not return that trace. If your code has logic reading a reasoning field from the old response, you need to remove that logic or write it defensively against the field arriving empty.
How the daily quota works on the free tier
qwen3.8-27b-free is offered free with a daily usage quota; once the quota is reached, requests are limited until the next day. That doesn't mean the quota runs out indefinitely — it renews every day — but the quota filling early on a busy day can cause requests to fail for the rest of that day.
In a production flow relying on this behavior, showing the user a clear message once the quota limit is approached, and defining a fallback path to a paid model where possible, prevents the flow from stopping entirely once the quota is reached.
- The quota renews every day; it's a daily ceiling, not unlimited.
- Surface the error clearly to the user once the quota is reached.
- Consider defining a paid fallback model for a critical flow.
The free tier shouldn't be the sole foundation of a critical production flow
The daily quota is, by the free tier's nature, a shared resource and can vary with usage intensity. Rather than depending solely on a free model in a critical flow that directly affects user experience, a plan for what kicks in once the quota is reached (a paid model, queueing, or a wait message to the user) should be designed upfront.
Frequently asked questions
What happens if I keep sending requests to qwen3.6-27b-free?
You'll get a 410 model_retired error. You need to update your code to the qwen/qwen3.8-27b-free identifier.
Can I use reasoning on the successor model?
This row does not return a reasoning trace; if you have a workflow relying on reasoning like the old row provided, don't expect that behavior here.
