The release of GLM-5.3-Flash sparked intense discussion — 918 upvotes and 455 comments on Hacker News within days. Developers are actively comparing it against established models like GPT-4o-mini and Claude-3.5-Haiku, but most conversations rely on anecdotal evidence or vendor-provided benchmarks. There's a clear gap for independent, reproducible data.
Existing solutions fall short: LMSYS Chatbot Arena offers community votes but lacks code-specific metrics and cost analysis. Artificial Analysis is comprehensive but updates slowly — new models wait 1-2 weeks for coverage. Official benchmarks from vendors are self-reported and often irreproducible. None provide a transparent, code-focused comparison with full test sets.
This is the perfect moment. GLM-5.3-Flash is at peak search and discussion velocity. A rigorous, independent benchmark published within 48 hours of release captures attention while interest is highest. With 20 carefully selected tasks from HumanEval and GSM8K, we provide actionable data for developers making model choices today.
We curated 20 coding and reasoning tasks — 10 from HumanEval and 10 from GSM8K — covering function synthesis, logic, and math. All prompts are versioned and published for full transparency.
Each model receives identical prompts via their official APIs. We measure accuracy, latency, and cost per 1K tokens. All calls run concurrently to minimize timing bias, with temperature set to 0 for reproducibility.
The final report includes a comparison table, representative outputs (good/medium/poor), and a one-click copy of the test set. Every number is traceable to a specific prompt and model response.
We have no affiliation with any model vendor. No sponsored results, no hidden preferences. The only agenda is accurate, reproducible data — we publish the exact prompts, responses, and scoring methodology.
GLM-5.3-Flash launched days ago. Our benchmark is already live — no waiting weeks for an update. You get fresh, relevant data while the model is still the talk of the developer community.
Every prompt, every response, every score is documented. The complete test set and API scripts are public. You can rerun the entire benchmark yourself and verify our results — no black boxes.
