inclusionAI LLaDA2.2-flash

One-line: Agent-oriented MoE diffusion language model making the LLaDA2 series’ first step into agentic use via Levenshtein Editing (DELETE/INSERT control tokens) — SWE-bench Verified 49.28, BFCL-V4 60.78, τ²-Bench 80.33, 128K context. ⚠ large (~100B total MoE); ⚠ diffusion runtime (custom_code, SGLang support pending). LLaDA2.2 announced July 2026; flash variant surfaced via the trending/lastModified window (08-20).

Efficiency

  • Active params: ~100B total MoE (card lists “total parameters (non-embedding): 100B”); active count not stated
  • Context length: 131,072 tokens (128K native)
  • VRAM (fp16 rough): ~200 GB for full weights (100B × 2 bytes) — ⚠ large, needs quant + large GPU cluster; not a laptop model
  • Runtime: needs trust_remote_code (custom llada2_moe architecture, diffusion decode with block_length/threshold/editing_threshold knobs); SGLang serving support listed as “coming soon” — no ready vLLM/Ollama path yet

What makes it notable

LLaDA2.2-flash is a genuinely novel direction for agentic coding: diffusion language modeling rather than the standard autoregressive next-token loop, extended with Levenshtein Editing so the model can DELETE and INSERT tokens during decoding for long-context tool use, multi-turn interaction, and error correction. It carries real agentic/coding numbers (SWE-bench Verified 49.28, τ²-Bench 80.33, BFCL-V4 60.78, MCP-Atlas 46.21) that land in the mid-tier of open agentic models, and it reports ~1.7× higher throughput than Ling-2.6-flash on the same agentic benchmarks (519 vs 303 TPS on SWE-bench Verified). Trade-offs: every number is lab-reported with no independent replication yet, the model is large (~100B MoE) with no production serving backend announced, the architecture is custom (not loadable by stock transformers without remote code), and deployment is unproven for real agent loops. For the local runner this is one to watch for the coming diffusion-agent serving story (SGLang) rather than something to drop into an agent today.
