Is OpenCode Zen’s Fledge Alpha Free
Fledge model? :distorted_face:
（I’ll add it to the AI site later—let’s see what it’s really made of）
Oh-oh
fledge verb. /fledʒ/
As an intransitive verb, it means “to grow feathers”; as a transitive verb, it includes “to raise a nestling until it can act independently” and “to feather an arrow,” among other meanings.

Fledge Alpha is an anonymous model that appeared on the OpenCode platform in early October 2026. Analysis indicates that it is not a single model, but rather a multi-model routing gateway.

Key Features

· Routing mechanism: Analysis of its response tokenizer patterns revealed that it routes requests to at least three different backends. Those identified include DeepSeek V4.1, Kimi (believed to be k3), and an unknown model.
· Technical fingerprint: It is based on the sglang gateway service. The API layer has no obvious censorship filters, suggesting that a Chinese organization is self-hosting open-source weights and providing them indirectly through a “secondary gateway.”
· Usage data: OpenCode’s weekly usage once reached 25B tokens, ranking 29th. Its input cache hit rate was as high as 92%, indicating highly efficient context reuse.

Specifications and Access

· Context window: 1,048,576 tokens (approximately 1 million), with a maximum output of 131,072 tokens.
· Access method: Available on OpenCode under the name Fledge Alpha Free; use requires a platform subscription plan.

Finally used the real ds4.1f（

I’ve been using it for the past few days and noticed that this model (router) seems to route to ds4.1f all the time. No matter how complex the task is on my end, it can finish it within 15 minutes. Overall, the backend is pretty good, but personally, I feel the frontend is a complete mess. It’s not even in the same league as Opus5.5… :ac01:
