Google officially introduced Gemini 4 Argon (succeeding the Gemini 3 series), making it available via the Gemini API and Google Cloud for developers and enterprise subscribers. A standout architectural upgrade is the expansion of the output token limit to an industry-leading 1 million tokens (up from 64K), allowing the model to handle extensive, multi-step agentic workflows and code generation in a single unbroken trajectory. Google launched Argon with introductory API pricing set at $2.00 per million input tokens and $10.00 per million output tokens (with a 95% discount for cached inputs), scheduled to shift to $4.00 and $20.00 respectively. Designed specifically for heavy-duty enterprise use cases, Argon demonstrates state-of-the-art performance across financial quantitative analysis, legal research benchmarks (such as Harvey’s Legal Agent Benchmark), and multi-lingual multimodal reasoning.
