GLM-5.1 is Z.ai's (formerly Zhipu AI) open-weight model released April 7, 2026 under the MIT license. It's a 744-billion-parameter Mixture-of-Experts architecture with 40 billion active parameters per token, a 200K-token context window, and a 131K maximum output length — and it became the first open-source model ever to lead SWE-bench Pro, scoring 58.4% versus Claude Opus 4.6's 57.3%. The training story is almost as remarkable as the performance. GLM-5.1 was trained entirely on approximately 100,000 Huawei Ascend 910B chips using the MindSpore framework — no Nvidia hardware was used at any point. That makes it one of the first frontier-tier models to demonstrate that the CUDA monoculture isn't technically mandatory for training state-of-the-art models. Z.ai became the first publicly traded foundation model company via a Hong Kong IPO in January 2026 (~$558M raised). The model is free to download from HuggingFace and also available via API at $0.95 per million input tokens. In agentic demonstrations, it has run autonomously for eight hours straight — 655 planning and execution iterations — without human checkpoints.

Qwen3.6-Max-Preview
Alibaba's #1-ranked agentic coding model — tops SWE-bench Pro, Terminal-Bench, and more

Qwen3.6-Max-Preview is Alibaba's flagship closed-weight model and currently holds the top position on five major agentic coding benchmarks: SWE-bench Pro, Terminal-Bench 2.0, SkillsBench, QwenClawBench, and QwenWebBench. Released April 20 as a preview API, it represents Alibaba's most aggressive push yet at the frontier of agentic AI. Unlike the open-weight Qwen3.6-27B and Qwen3.6-35B-A3B variants released alongside it, the Max model is proprietary and available only through the Qwen API. It's designed for complex multi-step coding tasks, autonomous terminal operation, and web-based agent workflows — the kind of tasks that require sustained planning over dozens of steps without human intervention. For the developer community, the benchmarks are eye-catching: claiming the #1 spot on SWE-bench Pro means it's outperforming Claude Opus 4.7, GPT-5, and Gemini Ultra 2.0 on autonomous software engineering tasks. Whether those numbers hold in production is the real question, but at competitive API pricing, Qwen3.6-Max is worth serious evaluation by any team running coding agents at scale.
Reviewer scorecard
“MIT license, top SWE-bench Pro score, $0.95/M via API. If your use case is agentic coding and you're not evaluating GLM-5.1, you're leaving real performance on the table. The 8-hour autonomous run capability is compelling for long-horizon task pipelines.”
“The SWE-bench Pro numbers are hard to ignore — if this actually resolves real GitHub issues at the rate the benchmark suggests, it's the best coding agent on the market right now. Early access reports from the terminal-bench community are positive, and the API latency is reportedly competitive with Claude. Worth evaluating seriously before your next agent project.”
“SWE-bench Pro is one benchmark. The broader coding composite (Terminal-Bench 2.0 + NL2Repo) still has Claude Opus 4.6 ahead at 57.5 vs GLM-5.1's 54.9. Running 744B locally requires hardware most teams don't own, and the API's Chinese jurisdiction will trigger compliance blockers for many organizations.”
“Alibaba runs their own benchmarks (QwenClawBench, QwenWebBench) that nobody outside can verify, which is a big red flag. SWE-bench Pro results need independent reproduction before taking them at face value. The 'preview' label also means API reliability, rate limits, and pricing are all subject to change — risky to build a production pipeline on.”
“The Huawei chip training story matters more than the benchmark ranking. If GLM-5.1 proves you can train frontier models without Nvidia at scale, it fractures the GPU supply chain narrative that's been shaping geopolitics and AI policy discussions for years. This is a proof of concept with enormous implications.”
“The fact that a Chinese tech company is releasing frontier-level agentic models that credibly compete with OpenAI and Anthropic is the real story here. Competition at the frontier drives down prices and forces capability improvements across the board. Alibaba's aggressive release cadence suggests this is just the beginning of a sustained push.”
“For creative workflows, the 744B MoE overhead is overkill and local deployment requires datacenter-grade hardware that's nowhere near indie studio territory. The MIT license is great, but the gap between 'free to download' and 'free to actually run' is vast at this parameter count.”
“For creative technologists building with code, the agentic capabilities matter — a model that can autonomously navigate a codebase and implement multi-file changes opens up a new class of creative tools. If the benchmarks hold in practice, this unlocks more ambitious generative projects without a human in the loop for every step.”
