Open Source LLMs Near Proprietary in Benchmarks
๐กOpen source 85% cheaper than GPT-5.1, just 4 QI behindโswitch for prod now.
โก 30-Second TL;DR
What Changed
Open source tops: GLM-4.7 at 68 QI, Kimi K2 at 67 QI
Why It Matters
Open source LLMs enable production use with near-parity quality at fraction of cost, pressuring proprietary pricing. AI builders can prioritize cost-effective inference for most reasoning tasks.
What To Do Next
Test DeepSeek V3.2 via deepinfra for $0.30/M inference in your production pipeline.

Web-grounded analysis with 7 cited sources.
๐ Enhanced Key Takeaways
- โขDeepSeek V3 achieved 88.5 on MMLU by December 2024, surpassing GPT-4o's 87.2 and marking the gap's collapse from 17.5 points in a year per Stanford AI Index 2025[2].
- โขGLM-4.7 excels with 94.2 HumanEval for code generation, 95.7 AIME 2025 math, and 85.7 GPQA Diamond science reasoning, topping open-source leaderboards[3].
- โขClosed models retain leads in competitive coding (e.g., +698 Elo on Codeforces) and SWE-bench Verified (+22.5 points), per early 2026 benchmarks[2].
- โขGLM-5 from Z AI leads February 2026 open-source rankings with 49.64 Quality Index and 203K context window under open license[4].
๐ Competitor Analysisโธ Show
| Feature | Open Source LLMs (e.g., GLM-4.7, DeepSeek V3.2) | Proprietary LLMs (e.g., Gemini 3 Pro, GPT-5.2) |
|---|---|---|
| Performance and accuracy | Rapidly improving, matching on MMLU/MATH-500, lead in some agentic/math tasks; lag in coding/reasoning[1][2][3] | Top-tier overall, leads in coding (Codeforces +698 Elo), SWE-bench (+22.5 pts), multimodal[1][2] |
| Cost and licensing | Free, permissive (MIT/Apache), infra-only costs ($0.30/M equiv.)[1][2][4] | Usage-based ($3.50/M), commercial licenses[1][2] |
| Customization | Full control, fine-tuning, self-hosting[1][4] | Limited tuning, no architecture access[1] |
๐ ๏ธ Technical Deep Dive
- โขDeepSeek V3.2: S-tier with 89.3 AIME 2025, 79.9 GPQA Diamond, 1421 Chatbot Arena; MIT License for commercial use[3].
- โขGLM-4.7: 94.2 HumanEval (best code gen), 95.7 AIME 2025, 85.7 GPQA Diamond, 84.9 LiveCodeBench[3].
- โขDeepSeek R1: 97.3 MATH-500, outperforms OpenAI o1 (~96.0)[2].
- โขGLM-5: 203K context window, leads open rankings at 49.64 QI[4].
๐ฎ Future ImplicationsAI analysis grounded in cited sources
Open-source LLMs will capture >50% enterprise inference volume by 2027
Proprietary edge narrows to <5% on coding benchmarks by end-2026
Hybrid open-proprietary stacks dominate enterprise AI
Open models enable customization/privacy while proprietary excel in multimodal/convenience, as in Sirion's hybrid CLM outperforming pure open[5].
