What it takes to serve Qwen2.5-Coder-7B (7.6B parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026.

SAVRN's Notes on Qwen2.5-Coder-7B

Pick the 7B when you want the Qwen2.5-Coder line without the 14B or 32B bill; it derives from Qwen2.5-7B, and Qwen trained the line on 5.5 trillion tokens of source code, text-code grounding and synthetic data. It needs 18.3 GB at 16-bit, 9.1 GB at 8-bit and 4.6 GB at 4-bit, so the cheapest option we list, one 192 GB MI300X at $1.85 an hour on demand, has room left for the 32,768-token context and for batching many requests on one card.

Apache 2.0 keeps deployment simple: commercial use, modification and redistribution allowed, you keep the license and NOTICE file, state significant changes, and you get an express patent grant from contributors. Two checks: the name carries no instruct tag, so verify that before wiring it to chat, and the config pairs a 131,072-token sliding window with the 32,768 context and cites the YaRN context-extension paper, so test long prompts.

Introduction

Qwen2.5-Coder is the latest series of Code-Specific Qwen large language models (formerly known as CodeQwen). As of now, Qwen2.5-Coder has covered six mainstream model sizes, 0.5, 1.5, 3, 7, 14, 32 billion parameters, to meet the needs of different developers. Qwen2.5-Coder brings the following improvements upon CodeQwen1.5:

  • Significantly improvements in code generation, code reasoning and code fixing. Base on the strong Qwen2.5, we scale up the training tokens into 5.5 trillion including source code, text-code grounding, Synthetic data, etc. Qwen2.5-Coder-32B has become the current state-of-the-art open-source codeLLM, with its coding abilities matching those of GPT-4o.
  • A more comprehensive foundation for real-world applications such as Code Agents. Not only enhancing coding capabilities but also maintaining its strengths in mathematics and general competencies.
  • Long-context Support up to 128K tokens.

Questions About Qwen2.5-Coder-7B

How much GPU memory does Qwen2.5-Coder-7B need?

About 18.3 GB at 16-bit and 4.6 GB at 4-bit: the weights (7.6B parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run Qwen2.5-Coder-7B on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

Can I use Qwen2.5-Coder-7B commercially?

Yes. Qwen2.5-Coder-7B is released under Apache License 2.0. The Apache License 2.0 is a permissive open-source license. It permits commercial use, modification and redistribution. It requires keeping the license and copyright notices and any NOTICE file, stating significant changes, and it includes an express patent grant from contributors.

What is Qwen2.5-Coder-7B's context length?

32,768 tokens, from the maximum position embeddings in its published configuration.
