# Is Clover-35B-A3B-Preview SOTA?

Pending benchmarks. Announced Oct 28, 2026; no independent results yet.

As of Nov 3, 2026, Clover-35B-A3B-Preview is pending benchmarks on isitsota: announced Oct 28, 2026, with no independent results on the boards we track yet.

DiffuSpace's first model: a text-only diffusion language model that writes in blocks, filling masked positions in parallel instead of one token at a time. It is derived from Qwen3.6-35B-A3B (35B total, about 3B active, mixture of experts), supports a thinking mode and 128K context, and is published on Hugging Face and ModelScope under Apache-2.0.

## What would let us call it

Verdicts use only independent boards we already track. Two consecutive snapshots are required before any crown.

- [x] Publicly announced with a source
- [x] Usable by the public (API or weights)
- [ ] Listed on an independent board we track
- [ ] Enough results for a rank in a category
- [ ] Holds across two snapshots (crowns only)

## What the lab claims

Self-reported. Shown for context; not used in any verdict.

- Lab claim: 680 tokens/s overall on internal agent workloads on one NVIDIA GB300 (BF16, batch size 1), and 515 tokens/s on agent tasks on one H200, against 365 tokens/s for a DFlash2-accelerated Qwen setup.
- Lab claim: 73.6 on SWE-bench Verified, 51.7 on Terminal-Bench 2.1, 65.3 on τ³ Overall, 83.8 on GPQA Diamond and 84.8 on MMLU-Pro, ahead of LLaDA2.2 flash, Mercury 2.5, Qwen3.6-35B-A3B and Qwen3.5-35B-A3B on its agent benchmarks.
- Lab claim (DiffuSpace on X): the first open-weight production diffusion language model (dLLM).
