  • Should You Use RAG or Fine-Tune Your LLM?
    Fine-tuned models often excel in tasks that require strict adherence to structure or formal constraints. For example, Cosine, which is an AI software engineering assistant thatโ€™s able to autonomously resolve bugs and build features, was able to achieve a SOTA score of 43.8% on the SWE-benchโ  verified benchmark. - Source: dev.to / about 2 months ago
  • Get Notifications on Telegram Every Time Your Favorite X Account Tweets
    Cosine (and the Genie assistant) helped by scoping the problem, writing clean Python code, setting up the GitHub workflow, and documenting every step. That eliminated setup friction and prevented common pitfalls (e.g., token handling, chat ID discovery, state management). - Source: dev.to / 10 months ago
  • AI Fluency: Build Smarter Code
    Iโ€™ve used AI to brainstorm app features, like a real-time chat tool, and it suggested integrations I hadnโ€™t considered. In 2025, generative AI can draft wireframes or write unit tests, freeing you to focus on design (these days Iโ€™m building a Sudoku game with cosine.sh and the AI gave me some ideas I didnโ€™t think of!). Use the AI to push your limits and see where it takes you! - Source: dev.to / 11 months ago
