Strengths
Qwen 3.5 35B activates only 3 billion parameters per token, delivering very low latency for real-time and high-throughput use.
Despite 35 billion total parameters, just 3B are active per token, keeping compute and cost minimal while retaining useful capability.
At $0.23 per 1M input and $1.82 per 1M output tokens, it is the cheapest model in the Qwen 3.5 family.
A 262,144-token context window lets even this compact model ingest large documents and long conversations in one request.

Qwen 3.5 35B API: ultra-fast, ultra-cheap MoE inference
Qwen 3.5 35B is Alibaba's compact mixture-of-experts model, with 35 billion total parameters but only 3 billion active per token. That sparse design makes it the fastest and cheapest model in the Qwen 3.5 family, built for low-latency, high-volume work.
Through YepAPI you call Qwen 3.5 35B with one API key on the chat endpoint at $0.23 per 1M input and $1.82 per 1M output tokens, with a 262K context window and 65K output.
What is Qwen 3.5 35B?
Qwen 3.5 35B is the compact mixture-of-experts model in Alibaba's Qwen 3.5 family. It has 35 billion total parameters but activates only about 3 billion per token, so it runs extremely fast and cheap while still handling everyday text-to-text tasks: chat, code, summarization, and extraction. Even at this small active size it keeps a 262K-token context window and up to 65,536 tokens of output, so it can take in large documents and long conversations. It is the model to choose when latency and per-token cost are the dominant concerns and you need capability spread across very high request volumes.
Build with Qwen 3.5 35B via YepAPI
Send chat completion requests to Qwen 3.5 35B over a single YepAPI key on the /v1/ai/chat endpoint — no Alibaba Cloud setup. Pass your messages and stream responses, with MoE routing handled server-side. Its speed makes it ideal for high-concurrency traffic, and because one key spans the catalog, you can serve bulk requests on 35B and escalate harder prompts to larger Qwen models without re-authenticating. It slots cleanly into real-time chat, autocomplete, and large batch pipelines.
Qwen 3.5 35B API pricing — $0.23/1M input, $1.82/1M output
Qwen 3.5 35B costs $0.23 per 1M input tokens and $1.82 per 1M output tokens on YepAPI — the lowest pricing in the Qwen 3.5 lineup. With only 3B active parameters, it delivers fast responses cheaply, so high-volume jobs like classification, tagging, and routing stay inexpensive. You pay only for tokens used, with no minimums, and one balance covers it alongside every other model on the platform.
Qwen 3.5 35B for real-time, high-volume tasks
Qwen 3.5 35B is built for speed and scale: real-time chat assistants, autocomplete and inline suggestions, request routing, and massive batch jobs where throughput and cost dominate. Its 3B active parameters keep latency low, while the 262K context lets it still handle large inputs when needed. For workloads measured in millions of requests, it is the economical, low-latency default in the Qwen family.
