Qwen3.6 35B A3B FP8

Multimodal agentic coding model with thinking preservation and 262K context

About model

Qwen3.6 35B A3B is the first open-weight release in Qwen's 3.6 series, a 35B parameter Mixture-of-Experts model that activates 3B parameters per token, served in FP8 on Together AI. It pairs a hybrid design combining Gated DeltaNet linear attention with gated attention layers, vision input, and 262K native context extensible up to 1M tokens, plus a new thinking preservation option that retains reasoning context from prior messages for iterative development. The release centers on agentic coding, reaching 73.4% on SWE-bench Verified, 80.4% on LiveCodeBench v6, and 51.5% on Terminal-Bench 2.0, with stronger frontend workflows and repository-level reasoning.
