Gemma 3 27B is Google's flagship open-weight Gemma 3 model, available at no cost via API. It supports vision input alongside text, with a 131K context window that handles longer documents comfortably. Intelligence benchmarks place it at 10.3 on the intelligence index, with MMLU-Pro at 0.669 and GPQA at 0.428, which is competent for a free model but far below commercial frontier options.

For businesses, the free pricing makes it attractive for content drafting, image-aware tasks, and general-purpose workflows where cost control is the priority. Coding and agentic scores are low (9.6 and 7.2 respectively), so it is not suited for software engineering or autonomous agent pipelines. Instruction-following (IFBench 0.318) and long-context reasoning (LCR 0.057) are also limited.

Teams looking to experiment with vision-capable open models at zero API cost will find Gemma 3 27B a reasonable starting point. For production workloads requiring reliable reasoning or coding, a paid model with stronger benchmarks is the better choice.
