List of IBM Granite Models
Granite 4.2 8B
ibm-granite/granite-4.2-8b
Granite 4.2 8B is a dense, decoder-only language model from IBM, post-trained from Granite 4.1 8B Base with native reasoning added on top. It switches between three modes: full chain-of-thought thinking, a low-effort abbreviated reasoning mode for easy questions, and non-thinking for direct answers, so the reasoning budget can be tuned per request. It was trained with agentic reinforcement learning to call tools, edit and run code, drive a terminal, and search the web inside real environments, and it emits tool calls in the OpenAI function-calling format for direct use with existing agent frameworks. It supports a 128K-token context window and 12 languages including English, German, Spanish, French, Japanese, and Chinese. On benchmarks, it scores 47.67 on SWE-Bench Verified, 86.67 on AIME25, 74.04 on MMLU-Pro, and 65.19 on Arena-Hard-v2, and it posts an Artificial Analysis Intelligence Index score of 20, well above the median of 9 for open-weight models of similar size. Released under Apache 2.0, it's a solid pick for agentic coding, tool-calling workflows, and multilingual tasks at a dense 8B parameter count.
ChatGranite 4.1 8B
ibm-granite/granite-4.1-8b
IBM Granite 4.1 8B is a dense, decoder-only language model from IBM, built for enterprise workloads like tool calling, RAG, code generation, summarization, and classification. It supports a 131K-token context window and 12 languages including English, German, Spanish, French, Japanese, and Chinese. Despite its compact size, the 8B model matches or outperforms IBM's previous-generation 32B Mixture-of-Experts model across benchmarks — scoring 69.0 on ArenaHard, 68.3 on BFCL V3 (tool calling), and 92.5 on GSM8K. It implements OpenAI-compatible tool calling and supports fill-in-the-middle for code completion. Its dense architecture makes it straightforward to fine-tune for downstream tasks. Released under the Apache 2.0 license, it's a strong pick for developers who need reliable enterprise capabilities at an efficient parameter count.
ChatGranite 4.0 Micro
ibm-granite/granite-4.0-h-micro
Granite 4.0 Micro is a 3B-parameter dense language model from IBM, built on a conventional transformer architecture and optimized for low-latency, cost-efficient workloads. Despite its compact size, it significantly outperforms its predecessor Granite 3.3 8B across the board — a model more than twice its size. It scores 16 on the Artificial Analysis Intelligence Index, placing ahead of Gemma 3 4B (15). In RAG benchmarks, it outperforms much larger models including Llama 3.3 70B and Qwen3 8B. The model natively supports tool calling, function calling, multilingual generation, fill-in-the-middle code completion, RAG, and structured JSON output, with a 128K token context window. It's a strong fit for agentic sub-tasks, API orchestration, and scenarios where speed and cost matter more than peak reasoning power.
