Grab an API key in Google AI Studio, and get started with the Gemini API Cookbook.

Last December, we released Gemini 1.0 and made the Gemini API available in Google AI Studio and Vertex AI for enterprise customers. In February, we released Gemini 1.5 Pro, the first model with a 1 million token context window. Last month, we added capabilities for native audio understanding, system instructions, JSON mode and more.

In parallel, we launched Gemma, our family of lightweight open models built from the same research and technology used to create the Gemini models. Since February, the 2B and 7B models have been downloaded millions of times, and we added variants last month for developers and researchers, like CodeGemma and RecurrentGemma.

Now Gemini and Gemma are getting even better. Today, we’re updating Gemini 1.5 Pro, introducing 1.5 Flash, rolling out new developer features and adding two new Gemma models.

Here are details on all the updates.

Gemini 1.5 Pro improvements and a new 1.5 Flash model

• Gemini 1.5 Pro: We made a series of quality improvements across key use cases, such as translation, coding, reasoning and more. You’ll see these updates in the model starting today, which should help you tackle even broader and more complex tasks.
• Gemini 1.5 Flash: This smaller Gemini model is optimized for narrower or high-frequency tasks where the speed of the model’s response time matters the most.
• Availability: Both models are available today in more than 200 countries and territories in preview and will be generally available in June.
• Natively multimodal with long context: Both 1.5 Pro and 1.5 Flash come with our 1 million token context window and allow you to interleave text, images, audio and video as inputs. To get access to 1.5 Pro with a 2 million token context window, join the waitlist in Google AI Studio or in Vertex AI for Google Cloud customers.
