## What is IBM Granite Code 8B (Ollama) best for with Atlas?

IBM Granite Code 8B (Ollama) excels within Atlas for developers in 2026 who need a substantial 125K token context window and the assurance of enterprise licensing. This 4.6GB model, served locally, allows Atlas to perform deep code analysis and generate comprehensive plans without sending sensitive code to third-party servers.

When integrated with Atlas, IBM Granite Code 8B (Ollama) provides a powerful combination of local execution and extensive context. Atlas can leverage the 125K token context window to search code with Axis, the hybrid semantic and keyword code search, and build its code index using local Ollama embeddings. This keeps all code off third-party servers, a critical feature for enterprise environments. The model's enterprise licensing and provenance documentation also simplify procurement, making it a viable option where research releases might not be. Atlas's ability to draft a plan in a read-only plan agent and ask for approval before switching to a build agent, combined with the deep context of Granite Code 8B, ensures well-informed and permission-gated operations. Furthermore, Atlas computes a unified diff for every file edit and surfaces it for approval, enhancing control over changes proposed by the agent.

## What are the cost and context tradeoffs for IBM Granite Code 8B (Ollama)?

IBM Granite Code 8B (Ollama) offers a compelling value proposition in 2026, being Free (self-hosted) while providing a 125K token context window, a significant advantage over models typically capped at 8K or 16K tokens. However, users must specifically pull the 'instruct' tag to access this extended context.

The primary benefit of IBM Granite Code 8B (Ollama) is its cost-effectiveness and context depth. Being Free (self-hosted), it eliminates ongoing API costs, making it an attractive option for long-term use within Atlas. The 125K token context window on the instruct tag is a standout feature, allowing Atlas to handle large files and complex projects with a single model call. This is particularly useful for Atlas's capabilities like reading git branches, status, and diffs, or staging and creating commits. However, it is crucial to note that the base variants of this model, such as the 8b-base tag, offer much smaller windows, typically 4K tokens. To fully utilize the 125K context, developers must ensure they pull the `granite-code:8b-instruct` tag. While the download size is 4.6GB, serving the model requires roughly 7GB of RAM, meaning it can run on an 8GB GPU card, but the 125K KV cache will consume additional memory, requiring incremental growth of Ollama's `num_ctx` setting.

## When should I choose a different model over IBM Granite Code 8B (Ollama)?

While IBM Granite Code 8B (Ollama) provides an exceptional 125K token context window and enterprise provenance, its raw coding ability trails models like Qwen2.5-Coder 7B. Developers in 2026 prioritizing peak benchmark performance for code generation over context depth or self-hosting benefits might find other options more suitable for Atlas.

The core tradeoff with IBM Granite Code 8B (Ollama) is its performance in raw coding benchmarks. If your primary use case for Atlas involves generating highly optimized or complex code snippets where absolute coding ability is paramount, you might find that models like Qwen2.5-Coder 7B offer superior results. IBM Granite Code 8B (Ollama) is designed to provide extensive context and clear enterprise licensing, not necessarily to win every coding benchmark. Atlas allows you to switch the active model and provider on the fly with favorites and recents, so you can easily experiment. If your project demands the highest possible code quality and you are willing to compromise on context window size, self-hosting, or enterprise provenance, then exploring other models might be beneficial. This model is ideal when the ability to process a vast amount of code at once, coupled with the security and cost benefits of self-hosting, outweighs the need for bleeding-edge code generation performance.

## Setup

1. Pull the instruct tag specifically: `ollama pull granite-code:8b-instruct` (4.6GB).
2. Register `granite-code:8b-instruct` in the `atlas.json` Ollama models map with `limit.context 125000` and `limit.output 8192`.
3. Grow Ollama's `num_ctx` toward the full 125K token window incrementally; the 7GB figure covers weights, not a 125K KV cache.
4. Set the active model to `ollama/granite-code:8b-instruct` and verify with `atlas models ollama`.
5. Run the codebase index with Ollama embeddings so an enterprise-licensed model is fed by an entirely on-premise retrieval layer.
