What the labs claim

Vendor claims — compare against the measured scores above. A claim is what a developer says about its own model, not an independent measurement.

GLM-5.2

Coding

  • “Advanced Coding with Flexible Effort: Stronger coding capabilities with multiple thinking effort levels to balance performance and latency”
    huggingface.co2026

Context Handling

  • “We propose IndexShare, which reuses the same indexer across every four sparse attention layers, reducing per-token FLOPs by 2.9x at a 1M context length.”
    huggingface.co2026

General

  • “Pure Open: An MIT open-source license - no regional limits, technical access without borders”

Qwen 3.6 Max (Preview)

Agentic / Tool Use

  • “Compared to Qwen3.6-Plus, this preview release brings stronger world knowledge and instruction following, along with significant agentic coding improvements across a wide range of benchmarks.”
    qwen.ai2026
  • “improved real-world agent and knowledge reliability performance”
    qwen.ai2026

Coding

  • “It achieves the top score on six major coding benchmarks - SWE-bench Pro, Terminal-Bench 2.0, SkillsBench, QwenClawBench, QwenWebBench, and SciCode - with substantial gains over its predecessor”
    qwen.ai2026
A higher number is not always a better model. Each score is task performance under a disclosed harness. Of the 10 measurements across 5 shared benchmarks, 10 single-evaluator or undisclosed-protocol reports; 100% are independently reproduced. GLM-5.2 and Qwen 3.6 Max (Preview) pricing is cross-check disputed — weigh cost claims with the same caution as benchmark wins. Follow any benchmark to its integrity grade before reading a win as decisive.
