TaglineQwen's open-source GPU kernel library that squeezes 2–3× more speed out of linear attention on NVIDIA Hopper hardware — if you're lucky enough to own one.Autonomous AI agent that actually finishes tasks.AI search done right. Cited answers, not chat theater.The one that actually gets text in images right.

PricingFree (MIT License, open-source)Free tier + $39-$199/moFree + $20/mo ProFree + $8/mo + $20/mo + $60/mo
Best forML engineers and researchers running Qwen3.x linear-attention models on H100/H200 clusters who need to close the gap between theoretical GDN efficiency and actual hardware throughput.People who want to hand off tasks entirely — trip planning, research, spreadsheet building.Replacing Google for any question where you want a cited answer in seconds.Anything with text — posters, ads, album covers, slide decks.
Strengths
  • 2–3× forward-pass and ~2× backward-pass speedup over FLA Triton kernels on Hopper GPUs
  • Gate-driven automatic intra-card context parallelism boosts SM utilization in long-sequence, small-head-count regimes without manual config
  • Hardware-friendly algebraic reformulation reduces Tensor Core, CUDA Core, and SFU overhead with no numerical precision loss
  • MIT licensed and fully open-source — drop it straight into Qwen3.x training and inference pipelines
  • General-purpose agent — research, book, build, analyze
  • Parallel task execution
  • Web browsing + file creation + coding
  • Sources every claim
  • Fast, current answers
  • Pro Search runs multi-step research
  • Spaces for persistent context
  • Best text rendering in the game
  • Strong free tier
  • Good for logos, posters, thumbnails
Weaknesses
  • Extremely narrow hardware requirement: SM90+ only (H100/H200, DGX Spark) with CUDA 12.8+ and PyTorch 2.8+ — useless outside Hopper-class clusters
  • GDN/Qwen-specific: not a drop-in replacement for FlashAttention-style softmax kernels, and won't help you if you're not running linear-attention Qwen models
  • Very new, minimal community adoption or third-party validation yet
  • Still hit-or-miss on complex multi-hour tasks
  • Can burn credits fast
  • Not a general chatbot
  • Answers can be shallow on complex topics
  • Aesthetic ceiling below Midjourney
  • Less style variety
Kai's verdictA genuinely impressive, laser-focused kernel optimization from the Qwen team — real speedups on real hardware — but its utility is gated behind Hopper GPUs and Qwen's GDN architecture, making it a niche power tool rather than a broadly useful library. (Verdict pending Phi's full review.)S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for text-in-image. Use this for posters, Midjourney for art.
