# Atlas with IBM Granite 4.1 8B in 2026 > IBM Granite 4.1 8B costs $0.05/$0.10 per Mtok with a 131,072 token context where max output equals the full window, so a large file rewrite fits in one call. IBM Granite 4.1 8B is the step up from Micro: a dense 8B model at $0.05/$0.10 per Mtok with a 131,072 token context where max output equals the full window. Symmetric-ish pricing and full-window output make it a surprisingly practical worker model inside Atlas. OpenRouter and W&B Inference both list Granite 4.1 8B at $0.05/$0.10 per Mtok. Output is only 2x input, where most models charge 4x to 10x, so verbose generations do not spike the bill. The limit is scale: 8B dense is a worker, not an architect. ## Key takeaways - Granite 4.1 8B output is only 2x input, $0.05 to $0.10 per Mtok, where most models charge 4x to 10x. - Max output equals the full 131,072 token context, so Granite 4.1 8B can emit a very large file rewrite in a single call without truncation. - Apache 2.0 licensing plus IBM's published data-provenance documentation is why enterprises pick Granite over a comparable Qwen or Llama at the same size. - 8B dense is a worker, not an architect. Granite 4.1 8B will not hold the cross-file invariants that a 120B MoE handles on a real refactor. - Granite 4.1 8B is not carried by the big first-party inference providers, so you reach it through OpenRouter or W&B Inference. ## Why does IBM Granite 4.1 8B charge only 2x for output tokens? IBM Granite 4.1 8B prices output at only 2x input, $0.05 to $0.10 per Mtok, where most models charge 4x to 10x. For an agent like Atlas that generates code continuously, a 2x output multiplier means verbose generations do not spike the bill the way they do elsewhere. Output pricing is where most coding agent budgets go wrong. A model that charges 8x for output turns every long generation into a surprise. Granite 4.1 8B's $0.05/$0.10 per Mtok structure means the cost of writing code is roughly twice the cost of reading it, which is a ratio you can actually plan against. Inside Atlas that changes what you allow the model to do. Atlas computes a unified diff for every file edit and surfaces it for approval before writing, so a model that emits a large diff cheaply is one whose output you review rather than ration. Both OpenRouter and W&B Inference list Granite 4.1 8B at $0.05/$0.10 per Mtok, so the price is consistent across the two routes. ## Can IBM Granite 4.1 8B emit a full file rewrite in one call? Yes. IBM Granite 4.1 8B has max output equal to its full 131,072 token context, so it can emit a very large file rewrite in a single call without truncation. That property is rare, and it is the strongest technical argument for Granite 4.1 8B in a coding agent. Most models cap output far below their context, which forces an agent to chunk a rewrite across multiple turns and hope the pieces reconcile. Granite 4.1 8B does not have that problem: the 131,072 token context and the 131,072 token max output are the same number. Because output runs to the full 131,072 tokens, Atlas's unified-diff review is the safety net. Read the diff before accepting a large rewrite. Atlas snapshots file changes as git patches so edits can be diffed and rolled back, so a large single-shot rewrite that goes wrong is a `git` operation away from being undone, not a manual repair job. ## Why do enterprises choose Granite 4.1 8B over Qwen or Llama at the same size? IBM Granite 4.1 8B is Apache 2.0 licensed with IBM's published data-provenance documentation, which is the whole reason enterprises pick Granite over a comparable Qwen or Llama at the same size. At $0.05/$0.10 per Mtok the price is not the differentiator. Provenance is. An 8B open-weights model is a commodity in 2026. What is not commodity is a paper trail describing what trained it. IBM publishes that for Granite 4.1 8B alongside an Apache 2.0 license, and for teams whose legal function has an opinion about their coding assistant, that documentation is the deciding factor. Atlas complements the same posture from the infrastructure side. Atlas can build its code index with local Ollama embeddings, keeping code off third-party servers, and every Atlas tool call is permission-gated against allow, ask, and deny rules before it runs. Provenance on the model, containment on the agent. ## What are the limits of IBM Granite 4.1 8B in Atlas? IBM Granite 4.1 8B is a dense 8B model, and 8B dense is a worker, not an architect. Granite 4.1 8B will not hold the cross-file invariants that a 120B MoE handles on a real refactor, regardless of how large its 131,072 token output window is. Granite 4.1 8B's honest limits are two. First, capacity: a large output ceiling lets it write a lot, but writing a lot is not the same as holding a mental model of a codebase. A multi-file refactor with real invariants belongs on a larger model, and Atlas lets you switch the active model and provider on the fly with favorites and recents, so keeping Granite 4.1 8B as `"small_model"` under a frontier build model is a reasonable middle ground. Second, distribution: Granite 4.1 8B is not carried by the big first-party inference providers in the registry, so you reach it through an aggregator like OpenRouter or W&B Inference rather than direct. ## How do you set up Atlas with IBM Granite 4.1 8B? Setting up Atlas on IBM Granite 4.1 8B takes three steps: export OPENROUTER_API_KEY, run `atlas models openrouter`, and pin the `ibm-granite/granite-4.1-8b` row in atlas.json. The model resolves at $0.05/$0.10 per Mtok with a 131,072 token context. Because IBM Granite 4.1 8B is reached through an aggregator, the auth step is OpenRouter's, not IBM's. Export OPENROUTER_API_KEY, or run `atlas login` and pick OpenRouter, then run `atlas models openrouter` and find the `ibm-granite/granite-4.1-8b` row to confirm the model resolved. Pin `"model": "openrouter/ibm-granite/granite-4.1-8b"` in atlas.json, or use it as `"small_model"` under a frontier build model, depending on which role you want it in. W&B Inference carries the same listing at the same $0.05/$0.10 per Mtok if you prefer that route. ## Setup 1. Export OPENROUTER_API_KEY (or run `atlas login` and pick OpenRouter). 2. Run `atlas models openrouter` and find the `ibm-granite/granite-4.1-8b` row. 3. Pin `"model": "openrouter/ibm-granite/granite-4.1-8b"` in atlas.json, or use it as `"small_model"` under a frontier build model. 4. Because output runs to the full 131,072 tokens, Atlas's unified-diff review is the safety net. Read the diff before accepting a large rewrite. 5. W&B Inference lists Granite 4.1 8B at the same $0.05/$0.10 per Mtok if you prefer that route over OpenRouter. ## FAQ ### how much does ibm granite 4.1 8b cost per million tokens IBM Granite 4.1 8B is $0.05/$0.10 per Mtok on both OpenRouter and W&B Inference.
