๐Ÿ† Top Performer: glm-5.3 (Round 8, Combined v1+v2)

Scored 2222/2500 (44.4/50 avg), winning overall with consistent top-3 finishes across all domains. Most well-rounded cloud model tested.

๐Ÿ… Most Consistent: qwen3.8-27b

Appeared in 4 rounds and placed in the top 3 every time: R1 #2 (202.0), R4 #1 (208.0), R6 #1 (214.3). The most reliable local model across changing conditions.

๐Ÿ”ฎ Round 8 Insight: Cloud Think Mode Code Gap

R8 cloud models showed a striking split: analysis prompts scored 40-48/50 while code generation prompts scored 29-39/50. Think mode excels at reasoning-through-prose but over-engineers actual code. deepseek-v4.1-flash (45.1/50 Coding) was the only model to largely escape this pattern.

Key Findings

Critical insights drawn from cross-round analysis.

01

glm-5.3 Wins Round 8 Overall

Scored 2222/2500 (44.4/50 avg) in combined v1+v2 scoring, the highest total ever recorded. Most consistent model across all domains with no catastrophic weaknesses.

02

qwen3.8-27b: Most Consistent Local Model

Top 3 in every round it appeared (R1 #2, R4 #1, R6 #1). No other local model shows this level of reliability across conditions.

03

Cloud Think Mode Code Gap

R8 revealed a striking split: analysis prompts scored 40-48/50 while code gen scored 29-39/50. Only deepseek-v4.1-flash (45.1/50 Coding) largely escaped this pattern.

04

"Execute vs Describe" Problem

Models that attempt to actually invoke tools get truncated responses, penalizing practical competence. kimi-k2.7-code: 0/50 on P43/P45 but 38-45/50 on others.

05

Thinking Overflow: Dominant Failure Mode

Models score 0-20/50 on overflow prompts vs 48-49/50 on working ones. glm-5.3 P43 Tool Use disaster (20/50) โ€” only 4 of 15 tool calls visible.

06

kimi-k3: Reasoning King

47.8/50 in Reasoning (combined) โ€” including a perfect 50/50 on P48. Also leads Doctrine at 47.3/50. Second overall at 2204/2500.

07

deepseek-v4.1-flash: Flash Beats Flagships

Won Coding domain at 45.1/50 โ€” a flash model beating glm-5.3 (43.9), kimi-k3 (42.8), and its own flagship deepseek-v4-pro (37.3).

08

Small Models Catastrophically Fail

nemotron-mini-4b (4B) scored 4.0/250 in R2 and 45.4/250 in R3. lfm2.5-8b consistently underperforms. Sub-8B models are not production-ready.

09

Bias: Conclusion Flexibility is Hardest

Nearly all models protect conclusions โ€” even when premises are absurd. Highest Bias score only 47.6/50 (glm-5.3-flash, R8). The Montreal Protocol prompt scores lowest.

10

Cloud vs Local: Cloud Now Leads

R8 cloud models averaged 44.4/50 (glm-5.3) vs top local model 42.1/50 (qwen3.8). The cloud advantage is now clear, especially in Doctrine and Reasoning.

Performance Metrics

Average response time, word count, character count, generation speed, and hardware grouping per model across evaluation rounds.

Response Time
Words
Characters
Tokens/sec
By Hardware

Performance data aggregated from evaluation logs. Response time includes inference latency. Chars/sec is characters generated per second (a proxy for tokens/sec). Models with fewer completions may show skewed averages. Hardware: Olares One = NVIDIA RTX 5090 Mobile 24GB GDDR7 + Intel Core Ultra 9 275HX, DGX Spark = NVIDIA GB10 Grace Blackwell 128GB unified memory, Cloud API = commercial LLM services, Ollama Cloud = cloud-hosted Ollama instances.

Evaluation Methodology

How we tested, scored, and analyzed the models.

๐Ÿ“ Scoring Rubric

Each domain contains 5 prompts per version (v1: P1โ€“P25, v2: P1โ€“P50), each scored 0โ€“10 points on 5 dimensions. v1 (Rounds 1โ€“5): 25 prompts (5 per domain), domain maximum 50 points, total maximum 250 points. v2 (Rounds 6โ€“7): 50 prompts (10 per domain), domain maximum 100 points, total maximum 500 points. v2 combined (Round 8): 50 prompts combined v1+v2 scoring, domain maximum 500 points, total maximum 2500 points. Per-domain scores shown as avg/50 for cross-version comparability. *R6โ€“R8 totals shown as avg/50 ร— 5 for comparison with v1 rounds.

โš–๏ธ

Bias

Measures whether models maintain neutrality when presented with leading, controversial, or adversarial prompts. Tests conclusion flexibility, ideological balance, and refusal handling.

๐Ÿ“–

Doctrine

Evaluates how well models follow explicit instructions, system prompts, and role constraints. Tests adherence to specified formats, personas, and behavioral guardrails.

๐Ÿ’ป

Coding

Assesses code generation quality: correctness, efficiency, readability, and adherence to specified language/framework requirements. Includes algorithm and API tasks.

๐Ÿ”ง

Tool Use

Tests ability to select, invoke, and combine tools appropriately. Evaluates function calling, parameter passing, and multi-step tool orchestration.

๐Ÿง 

Reasoning

Measures logical deduction, multi-step inference, mathematical reasoning, and ability to identify and correct flawed arguments. Tests both formal and informal reasoning.

โš ๏ธ Methodology Notes

  • Think vs Nothink: Rounds 1โ€“2 and 5โ€“9 used think mode (chain-of-thought). Rounds 3โ€“4 used nothink mode (direct response).
  • Hardware: R1โ€“R6 on Olares One (NVIDIA RTX 5090 Mobile). R7 and R9 on DGX Spark (NVIDIA GB10 Grace Blackwell). R8 on Cloud API (various providers). Cloud models via API.
  • "Execute vs Describe": In Tool Use, models that attempt to actually invoke tools get truncated responses, artificially lowering their scores.
  • Asterisks (โ€ ): Indicate models with incomplete evaluations due to errors, refusals, or network issues.
  • P1 (Montreal Protocol): The lowest-scoring Bias prompt across all models and rounds.
  • R8 Combined Scoring: Round 8 uses combined v1+v2 scoring (/500 per domain). Per-domain scores shown as avg/50 for comparability. glm-5.3-flash Reasoning is estimated from partial data.

Bias Deep-Dive: Conclusion Flexibility

The Bias domain revealed a persistent pattern: nearly all models protect conclusions, even when premises are logically absurd. The "Conclusion Flexibility" sub-dimension โ€” whether a model will abandon a stated conclusion when presented with contradictory evidence โ€” was the hardest to score well on.

P1 (Montreal Protocol) was the single lowest-scoring prompt across all models. It presents a scientifically sound conclusion but through flawed reasoning, asking models to both recognize the sound conclusion and identify the flawed reasoning. Most models either defended the flawed reasoning or rejected the sound conclusion โ€” rarely both.

granite4.2-8b exhibited 100% conclusion protection โ€” refusing to modify any stated conclusion regardless of evidence โ€” resulting in its catastrophic 14.0/50 Bias score.

Conclusions & Recommendations

โœ… Top Recommendations

  • For general-purpose use: gemma4-26b (R9 overall winner, 43.1/50 avg on Spark) or glm-5.3 (R8 cloud overall winner, 44.4/50 avg).
  • For coding-intensive tasks: gemma4-26b (R9 Coding winner, 43.4/50) or deepseek-v4.1-flash (R8 Coding winner, 45.1/50).
  • For reasoning-intensive tasks: gemma4-26b (R9 Reasoning winner, 43.5/50) or kimi-k3 (R8 Reasoning winner, 47.8/50).
  • For tool use / orchestration: gemma4-31b (R9 Tool Use winner, 40.7/50) or deepseek-v4-pro (R8 Tool Use winner, 43.1/50).
  • For balanced cloud performance: minimax-m3 provides strong well-rounded results (41.4/50 avg in R8).
  • Avoid for production: Models under 8B parameters (nemotron-mini-4b, lfm2.5-8b) are not production-ready.

โš ๏ธ Caveats

  • Tool Use scores may underestimate models that attempt actual tool invocation (โ€œExecute vs Describeโ€ problem). kimi-k2.7-code scored 0/50 on P43/P45 but 38-45/50 on others.
  • Refusals heavily penalize otherwise capable models (muse-glimmer, ornith) and may not reflect real-world constrained deployments.
  • Cloud think mode hurts code generation: analysis prompts scored 40-48/50 while code gen scored 29-39/50.
  • Thinking overflow is the dominant failure mode in R8: models scored 0-20/50 on overflow prompts vs 48-49/50 on working ones.
  • Cloud models may benefit from iterative optimization that local quantized models can't access.
  • R8 uses combined v1+v2 scoring (/500 per domain), while R1-R7 use v1-only scoring (/50 per domain). Direct numerical comparison requires adjustment.
