Google has officially removed the Gemini 1.5 Flash and 1.5 Pro models from the Gemini app, following the stable release of Gemini 2.0 Flash. This change impacts users across web, Android, and iOS platforms.
Transition to 2.0 Flash
Nearly three weeks after the launch of Gemini 2.0 Flash, Google phased out its 1.5 models, aligning all free and paid users with the latest iteration. The previous models served specific functions:
- 1.5 Pro: Designed for tackling complex tasks
- 1.5 Flash: Focused on providing everyday assistance
The new 2.0 Flash model now replaces these versions, delivering enhanced everyday task performance with increased speed and accuracy. Meanwhile, Gemini Advanced subscribers gain access to additional premium features, including:
- 1 million token context window (handling up to 1,500 pages for file uploads)
- Custom Gems creation
- Saved Info & Recall features
- Deep Research, still utilizing 1.5 Pro
Unusual Timing of 1.5 Pro Removal
Google’s decision to remove 1.5 Pro before launching 2.0 Pro out of preview raises some intrigue. The experimental 2.0 Pro model currently lacks real-time information access and some Gemini features, such as file uploads. However, the developer API version supports a massive 2 million token context window, indicating Google’s direction towards more advanced capabilities.
Performance Gains with 2.0 Flash
Despite the absence of 2.0 Pro in its final form, 2.0 Flash officially outperforms 1.5 Pro across multiple benchmarks, including:
- Code generation
- Factual accuracy
- Mathematical reasoning
- Multi-step problem solving
- General speed and efficiency (running at twice the speed of its predecessor)
Gemini Advanced Model Picker
For Gemini Advanced subscribers, the updated model selection now includes:
- 2.0 Flash: Optimized for everyday tasks, with additional premium features
- 2.0 Flash Thinking Experimental: Designed for multi-step reasoning
- 2.0 Flash Thinking Experimental with Apps: Incorporates reasoning across YouTube, Maps, and Search
- 2.0 Pro Experimental: Ideal for handling complex tasks
- 1.5 Pro with Deep Research: Offers in-depth analysis and extended context window
Conclusion
The removal of Gemini 1.5 Flash and 1.5 Pro signifies Google’s commitment to refining its AI models with improved performance and efficiency. While 2.0 Flash has already surpassed 1.5 Pro, all eyes are now on 2.0 Pro, expected to bring even greater advancements in AI capabilities once it exits the experimental phase.
