Google has released two stable versions of Gemini 1.5 API models for developers, promising greater performance and lower app production costs.

On Sept. 24, Google announced the launch of stable versions of Gemini 1.5 Pro (gemini-1.5-pro-002) and Gemini 1.5 Flash (gemini-1.5-flash-002). Compared to the previous 001 models, the new production-ready Gemini models have displayed significant improvements in code generation, math, reasoning and video analysis, among others.

According to Google’s release notes, both Gemini 1.5 models offer significant gains in factuality and reduce model hallucinations, instruction following, multilingual understanding in 102 languages, SQL generation and audio and document understanding.

Google reduced the summarization lengths for both models and advised chat-based product developers with options to increase the API’s conversational capabilities.

From Oct. 1, Gemini 1.5 Pro API prices on prompts less than 128,000 tokens will be reduced to 64% for input tokens, 52% for output tokens and 64% for incremental cached tokens. 

“To make it even easier for developers to build with Gemini, we are increasing the paid tier rate limits for 1.5 Flash to 2,000 RPM and increasing 1.5 Pro to 1,000 RPM, up from 1,000 and 360, respectively,” the announcement read.
