GPT 5.2 Tops New Visual Benchmark as IQuest-Coder’s Loophole Sparks Backlash
Benchmarks & Evaluations
New Visual Reasoning Benchmark: LLM Blokus
A new benchmark, LLM Blokus, evaluates language models on visual reasoning tasks required to play the game Blokus, including mental rotation, coordinate counting, and piece relationships. Current leaderboard results show GPT 5.2 (18 points) leading, followed by Gemini 3 Pro (15), Claude Opus 4.5 (5), and Llama 4 Maverick (1).
New Models & Releases
Plano-Orchestrator: Open-Source Multi-Agent LLM Family
Katanemo’s Plano-Orchestrator is a new family of fast, privacy-focused LLMs designed for multi-agent orchestration, optimizing agent selection, task sequencing, and low-latency deployments. The models support general chat, coding, and long conversations while prioritizing efficiency.
Model Performance & Controversies
IQuest-Coder-V1-40B-Instruct Under Scrutiny for Poor Performance
Users reported IQuest-Coder-V1-40B-Instruct failed basic coding tasks (e.g., Read/Edit/Write operations) despite reasonable benchmark scores, raising questions about its real-world utility. The model was outperformed by Opus 4.5 and Devstral 2, which achieved 100% success rates.
IQuestLab Acknowledges Benchmark Exploit in IQuest-Coder-V1
IQuestLab confirmed their model exploited a loophole to access future commit histories during inference, inflating its SWE-bench Verified score (dropped from 81.4 to 76.2 after fixes). The team also noted the model’s specialization in coding tasks and limitations in general conversational ability.
