What is the largest context window available with Together AI (gateway) for Atlas?

Together AI (gateway) offers models with varying context windows for Atlas, with the largest being up to 1 million tokens on Qwen3.7 Max. This substantial capacity supports complex coding tasks in 2026, allowing Atlas to process extensive codebases and documentation.

How does Together AI (gateway) pricing compare to other providers for Atlas?

Together AI (gateway) offers competitive pricing for Atlas, such as Qwen3.7 Max at $1.25 per million input tokens and $3.75 per million output tokens, which is half the first-party rate from Alibaba. Kimi K2.7 Code is available for $0.95 / $4 per Mtok, providing cost-effective options for developers in 2026.

Can I use proprietary models like GPT-5 or Claude with Together AI (gateway) in Atlas?

No, Together AI (gateway) exclusively serves open-weights models. Proprietary models like GPT-5 or Claude are not available through this gateway for Atlas users in 2026. If these models are required, an alternative provider must be selected.

Why would I choose Together AI (gateway) over a model's direct API for Atlas?

Many teams choose Together AI (gateway) for Atlas because it provides US-hosted inference for models like DeepSeek, Qwen, and Kimi, whose first-party APIs are often based in China. It also offers competitive pricing, such as Qwen3.7 Max at $1.25 / $3.75 per Mtok, and a broad catalog under one key.

How do I configure Atlas to use a specific Together AI (gateway) model?

To configure Atlas, first export your `TOGETHER_API_KEY`. Then, run `atlas models togetherai` to view available model IDs. Finally, select your desired model from `/models` and pin it in your `atlas.json` configuration file, for example, `"model": "togetherai/Qwen/Qwen3-Coder-480B-A35B-Instruct-FP8"`.

Does Together AI (gateway) support the Qwen3-Coder line for Atlas?

Yes, Together AI (gateway) serves the full Qwen3-Coder line for Atlas, including the 480B variant. This is particularly useful as the 480B variant requires 250GB to run locally, which Together AI handles for you, making it accessible to Atlas users in 2026.

What kind of models are available through Together AI (gateway) for Atlas?

Together AI (gateway) provides a broad catalog of open-weights models for Atlas, including popular options like Qwen3.7 Max, DeepSeek V4 Pro, and Kimi K2.7 Code. It is the go-to platform when you want to leverage open models at scale without the overhead of running local hardware in 2026.

Atlas with Together AI (gateway) in 2026

Together AI (gateway) is ideal for Atlas users in 2026 seeking a wide selection of open-weights models, including Qwen3.7 Max and DeepSeek V4 Pro, without managing local hardware. It provides US-hosted inference for models often based in China, with pricing like Qwen3.7 Max at $1.25 / $3.75 per Mtok, making it a cost-effective choice for scaling open-source AI.

What is Together AI (gateway) best for with Atlas?

Together AI (gateway) excels at providing Atlas users in 2026 with a vast selection of open-weights models, including the powerful Qwen3.7 Max, which can handle up to 1 million tokens. This gateway is particularly strong for teams needing US-hosted inference for models like DeepSeek and Kimi, which often have first-party APIs in China.

Together AI (gateway) serves as a comprehensive hub for open-weights models, making it an excellent choice for Atlas, the terminal-native AI coding agent. Developers in 2026 can leverage its broad catalog to access models such as Qwen3.7 Max, DeepSeek V4 Pro, and Kimi K2.7 Code, all under a single API key. A key advantage is its provision of US-hosted inference for models whose first-party APIs are typically located in China, addressing potential latency or data residency concerns. For instance, the full Qwen3-Coder line, including the demanding 480B variant that requires 250GB to run locally, is readily available through Together AI (gateway). Atlas allows you to switch the active model and provider on the fly, making it simple to experiment with different open-weights models from Together AI (gateway) to find the best fit for specific coding tasks, from code search with Axis, the hybrid semantic and keyword retrieval system, to drafting plans in the read-only plan agent.

What are the cost and context window tradeoffs for Together AI (gateway)?

Together AI (gateway) presents a varied pricing structure for Atlas users in 2026, with Qwen3.7 Max costing $1.25 / $3.75 per Mtok, significantly less than Alibaba's first-party rate. Context windows also vary, reaching an impressive 1 million tokens on Qwen3.7 Max, offering substantial capacity for complex coding tasks.

When considering Together AI (gateway) for Atlas, developers in 2026 will find a range of pricing and context window options. For example, Qwen3.7 Max is priced at $1.25 per million input tokens and $3.75 per million output tokens, which is half of Alibaba's first-party rate of $2.50 / $7.50 for the same model. DeepSeek V4 Pro is available at $1.74 / $3.48 per Mtok, and Kimi K2.7 Code at $0.95 / $4 per Mtok. The context window varies by model, with Qwen3.7 Max offering an impressive capacity of up to 1 million tokens, which is highly beneficial for Atlas when indexing code by AST declarations using tree-sitter or processing large codebases. The primary tradeoff is that pricing can vary significantly by the specific model and its quantization tier, meaning the exact model ID selected can impact costs. This requires careful selection and understanding of the available options within the Together AI (gateway) catalog to optimize for both performance and budget.

When should I choose a different model provider for Atlas?

While Together AI (gateway) offers a robust selection of open-weights models for Atlas in 2026, it is not suitable if your project requires proprietary models like Claude, GPT-5, or Gemini. This gateway exclusively serves open-weights models, meaning these closed-source options are simply not available through its API.

Developers using Atlas in 2026 should consider alternative model providers if their workflow necessitates access to closed-source, proprietary large language models. Together AI (gateway) is explicitly an open-weights only platform, meaning it does not offer models such as Claude, GPT-5, or Gemini. If your team's requirements or existing integrations are built around these specific proprietary models, then Together AI (gateway) will not meet those needs. Atlas, the terminal-native AI coding agent, is designed to let you switch the active model and provider on the fly, making it straightforward to integrate and test other providers that do offer these closed-source alternatives. This flexibility ensures that you are not locked into a single provider and can always select the best tool for the job, whether it is an open-weights model from Together AI (gateway) or a proprietary model from another service.

Setup

011: Export your Together AI API key: `export TOGETHER_API_KEY=...`
022: Run `atlas models togetherai` in your terminal to view the exact, case-sensitive model IDs available through Together AI (gateway).
033: Select a desired model from the `/models` interface within Atlas.
044: Pin your chosen model in your `atlas.json` configuration file. For example: `"model": "togetherai/Qwen/Qwen3-Coder-480B-A35B-Instruct-FP8"`.
