What is the memory requirement for Qwen3 235B-A22B (local via Ollama) with Atlas?

Qwen3 235B-A22B (local via Ollama) requires approximately 140 GB of memory at 4-bit quantization. This means it needs a high-end machine such as a 192 GB Mac Studio or a multi-GPU server to run effectively with Atlas.

Is Qwen3 235B-A22B (local via Ollama) free to use with Atlas?

Yes, Qwen3 235B-A22B (local via Ollama) is Free because it is self-hosted. There are no per-token costs or subscription fees, though you must provide the necessary hardware.

What is the context window size for Qwen3 235B-A22B (local via Ollama)?

Qwen3 235B-A22B (local via Ollama) features a native context window of 128K tokens (131,072). Atlas users should cap `limit.context` to fit their specific memory budget.

How fast is Qwen3 235B-A22B (local via Ollama) for code generation in Atlas?

Qwen3 235B-A22B (local via Ollama) generates far faster than its 235B total parameters suggest, because only 22B parameters activate per token. Once the model weights are resident in memory, generation speed is closer to that of a 22B model.

Can I run Qwen3 235B-A22B (local via Ollama) on my laptop with Atlas?

No, Qwen3 235B-A22B (local via Ollama) is not a laptop model. Its memory floor is brutal, requiring roughly 140 GB of memory. Partial offload to system RAM will destroy throughput and make the experience with Atlas very slow.

Does Qwen3 235B-A22B (local via Ollama) keep my code private when used with Atlas?

Yes, a significant strength of Qwen3 235B-A22B (local via Ollama) is that it is self-hosted. This means no code leaves your network, ensuring complete data privacy for your Atlas-driven development.

What Atlas features benefit most from Qwen3 235B-A22B (local via Ollama)'s capabilities?

Atlas features like Axis, its hybrid semantic and keyword code search, and its ability to build code indexes with local Ollama embeddings benefit greatly. The model's frontier-class reasoning also enhances Atlas's planning agent and its ability to compute unified diffs for approval.

Atlas with Qwen3 235B-A22B (local via Ollama) in 2026

Qwen3 235B-A22B (local via Ollama) is an excellent choice for Atlas users in 2026 seeking frontier-class reasoning and fast generation speeds for coding tasks, all while keeping their code entirely within their network. This self-hosted model offers a substantial 128K token context window and is completely free to use, provided you have the significant hardware to run its 140 GB footprint.

What is Qwen3 235B-A22B (local via Ollama) best for with Atlas?

Qwen3 235B-A22B (local via Ollama) excels within Atlas for developers requiring frontier-class reasoning and rapid code generation without external data exposure. Its 22B active parameters out of 235B total enable speeds closer to a 22B model, making it a strong contender for complex coding tasks in 2026.

For Atlas users, Qwen3 235B-A22B (local via Ollama) offers a powerful combination of advanced reasoning and data privacy. Because it is self-hosted, all code and interactions remain within your network, a critical advantage for sensitive projects. Atlas can leverage Qwen3's capabilities for tasks like searching code with Axis, its hybrid semantic and keyword retrieval, or building its code index using local Ollama embeddings. The model's ability to generate far faster than its total parameter count suggests, due to only 22B parameters activating per token, means that once the 140 GB model weights are resident in memory, Atlas can execute complex plans and generate code efficiently. This makes it ideal for developers who prioritize both performance and strict data sovereignty in their AI coding agent.

What are the cost and context window tradeoffs for Qwen3 235B-A22B (local via Ollama)?

Qwen3 235B-A22B (local via Ollama) offers a compelling value proposition in 2026: it is entirely Free (self-hosted) and boasts a native 128K tokens (131,072) context window. However, this comes with a significant hardware cost, requiring roughly 140 GB of memory, which is not suitable for typical laptop setups.

The primary advantage of Qwen3 235B-A22B (local via Ollama) is its zero per-token cost, as it is self-hosted. This eliminates ongoing operational expenses associated with API-based models. Its 128K token context window is frontier-class, allowing Atlas to maintain a deep understanding of large codebases, read git branches, status, and diffs, and process extensive file changes. However, the tradeoff is a brutal memory floor. The model requires approximately 140 GB of memory at 4-bit quantization, necessitating a high-end machine like a 192 GB Mac Studio or a multi-GPU server. Attempting to run Qwen3 235B-A22B (local via Ollama) with insufficient memory, leading to partial offload to system RAM, will severely degrade throughput and make prompt processing on a large Atlas context slow, even if generation is fast. Developers must budget for substantial hardware to fully realize its benefits.

When should I choose a different model over Qwen3 235B-A22B (local via Ollama) for Atlas?

While Qwen3 235B-A22B (local via Ollama) offers frontier-class reasoning and privacy, it is not the right choice for every Atlas user in 2026. If your hardware budget does not include a machine with at least 192 GB of unified memory or VRAM, or if you require fast prompt processing for very large contexts, a different model might be more suitable.

Developers should consider alternative models if their environment cannot meet the demanding hardware requirements of Qwen3 235B-A22B (local via Ollama). The model's 140 GB memory footprint means it is explicitly not a laptop model; partial offload to system RAM will severely impact performance and user experience within Atlas. Furthermore, while generation speed is fast once weights are resident, prompt processing on a large Atlas context can still be slow. If your workflow frequently involves extremely large prompts that need rapid processing, or if you need a model that can run effectively on more modest hardware, a smaller, more efficient local model or a cloud-based API model might provide a better balance of cost, performance, and accessibility for your Atlas agent. Atlas lets you switch the active model and provider on the fly, making experimentation straightforward.

Setup

01Confirm memory headroom: Run `atlas device` first to confirm you have the unified memory or VRAM headroom required before pulling the model.
02Pull the model: Execute `ollama pull qwen3:235b-a22b` in your terminal. Expect this process to download roughly 140 GB of data at the default quantization.
03Configure Ollama provider: Add the following provider block to your `atlas.json` configuration file: ```json { "providers": { "ollama": { "api_base": "http://localhost:11434", "models": { "qwen3:235b-a22b": { "limit": { "context": 65536, "output": 16384 } } } } } } ```
04Set active model: Update your Atlas configuration to use this model by setting `"model": "ollama/qwen3:235b-a22b"`.
05Verify installation: Run `atlas models ollama` to confirm that Atlas recognizes and can access the Qwen3 235B-A22B (local via Ollama) model.
