🚀 GigaChat 3.5 Reasoning — a new open-source LLM that thinks before it answers. It breaks problems into stages, builds a plan, checks intermediate results, and self-corrects. Built on GigaChat 3.5 Ultra, it explores multiple step-by-step reasoning paths for math & coding, using automated verification to reinforce correct answers. ⚡️ Proprietary linear attention makes it highly efficient on long contexts, retaining key points without re-matching from scratch. It’s also token-efficient: uses 37% fewer tokens than DeepSeek V4 Flash Preview on math problems! 📈 Benchmark gains over non-reasoning version: • IFBench: 44 → 77 • Natural Plan: 64 → 80 • LiveCodeBench v6: 56 → 85 📦 MIT license.

Open mentionGigaChat 3.5 Reasoning: Advanced step-by-step problem solving GigaChat 3.5 Reasoning is a new open-source LLM designed to reason, not just respond. Built on GigaChat 3.5 Ultra, it processes math and coding tasks by exploring multiple step-by-step reasoning paths, using automated verification to reinforce correct trajectories. This enables autonomous multi-step planning, external tool invocation, and self-correction. The model features a proprietary linear attention architecture, optimizing long-context efficiency by retaining key processed points rather than re-matching from scratch. It is highly token-efficient, consuming on average 37% fewer tokens than DeepSeek V4 Flash Preview on math problems. Benchmark gains over the non-reasoning version: • IFBench: 44 → 77 • Natural Plan: 64 → 80 • LiveCodeBench v6: 56 → 85 Open-sourced under the MIT license.
