Composer 2.5 vs Gemini 3.5 Flash

The article discusses Cursor's release of the Composer 2.5 model, claiming it is currently the best coding model with excellent performance and cost-effectiveness.

The "smart, fast, cheap" trilemma limitation of AI models has been broken by Cursor's Composer 2.5, which can simultaneously achieve all three characteristics.

After the $10K Cursor credit expired, users reported that Agent Window mode almost completely replaced traditional IDEs; GPT-5.5 and Composer 2.5 performed well in different scenarios, especially Composer 2.5 Fast mode which is fast and good at generating flowcharts, but default output is not Markdown and cannot be copied directly as Markdown, affecting efficiency.

Cursor has released an SDK supporting Python and TypeScript for building custom AI agents using Composer 2.5, offering a 90% discount on Composer usage during a limited-time promotion.

The Cursor team achieved Composer 2.5 through reinforcement learning training rather than prompt engineering, with their large-scale RL program running inference on Fireworks, indicating that self-trained models will be the only way to maintain competitive moats after 2027.

Cursor released Composer 2.5, using Kimi as a base with 85% compute for self-training. It matches Claude Opus 4.7 performance at 1/10th the cost via targeted RL and 25x synthetic data.

The Cursor SDK now supports programmatic access to Composer 2.5's frontier intelligence features via Python and TypeScript, allowing developers to build their own AI agents with 90% discount during the long weekend.

Composer 2.5 is having a moment. Worth a look at how the team actually got here.

Google announced several AI updates at I/O 2026 including the faster and cheaper Gemini 3.5 Flash and the powerful multimodal model Gemini Omni, sparking community debate.

Google Antigravity 3.0 receives significant updates including Gemini 3.5 Flash, Teamwork Preview (now available to all paid users), a scientific workbench, and low thinking effort options, signaling its evolution from an AI editor to a full agent platform.

Gemini Spark simplifies daily workflows through Gemini 3.5 Flash technology, connecting with Google Workspace apps like Docs and Gmail to execute complex tasks.

Google introduces new AI search features including conversational mode, image/file uploads, and personal intelligence integration to enhance user experience.

Google claimed its AI agents built an OS for $916, but the article points out lack of transparency and verification details, limiting practical significance.

Claude Opus 4.8 is Anthropic’s rapid revision of the controversial 4.7 model, prioritizing improved ambiguity handling to restore the user-friendly ‘vibes’ of 4.6; though it outperforms GPT-4.5 on official benchmarks, real-world engineering benchmark DeepSWE shows GPT-4.5 currently leads—and 4.8 hasn’t been tested yet.

苹果正在使用一个1.2T参数的定制版Google模型来改进下一代Siri，这将显著提升其性能和速度。

At Google I/O, the company launched the Gemini 3.5 Flash model, emphasizing speed and enhanced free-tier access as key reasons to switch from ChatGPT or Claude.
