7 Nano Banana Pro Prompts that You Should to Try!

Google’s Nano Banana Pro (the marketing name for the Gemini 3 Pro Image family) landed as a major step forward in image generation and editing tools. It’s designed to combine Gemini 3’s language and reasoning strengths with pixel-level image control, and it’s already being rolled into the Gemini app, Google Workspace products, Adobe Firefly/Photoshop integrations, […]

How to Prompt Nano banana Pro For Best

Google launched Nano Banana Pro (the Gemini 3 Pro Image model) on November 20, 2025. It’s a high-fidelity image-generation and editing model that improves on the original Nano Banana with much better text rendering, deeper world knowledge, and support for combining many reference images (up to 14). This article covers what it is, how it […]

How Much Does Claude Opus 4.5 Cost — and is it worth it?

Claude Opus 4.5 is Anthropic’s newest “Opus-class” model (released in late November 2025). It’s positioned as a top-tier model for professional software engineering, long-horizon agentic workflows, and high-stakes enterprise tasks, and Anthropic intentionally priced it to make high capability more accessible to production users. Below I unpack what the Claude Opus 4.5 API is, how […]

Claude Opus 4.5: what is it like — and how much will it cost?

Anthropic’s Claude family has been one of the fastest-moving threads in the 2025 frontier-model race. Over the past few weeks several leaks, social posts and investigative write-ups have pointed to an upcoming Claude Opus 4.5 (often shortened to “Opus 4.5”) — internally referenced by some sources as Neptune V6 — and to the model being […]

Gemini 3 Pro vs Claude 4.5 Sonnet for Coding: Which is Better in 2025

Both Gemini 3 Pro (Google/DeepMind) and Claude Sonnet 4.5 (Anthropic) are 2025-era flagship models optimized for agentic, long-horizon, tool-using workflows — and both place heavy emphasis on coding. Claimed strengths diverge: Google pitches Gemini 3 Pro as a general-purpose multimodal reasoner that also shines at agentic coding, while Anthropic positions Sonnet 4.5 as the best […]

Create a MCP Server for Claude Code — a practical, up-to-step guide

The Model Context Protocol (MCP) is an open standard that lets models like Anthropic’s Claude and developer tools like Claude Code call out to external tools, data sources and prompts in a safe, standard way. This guide will walk you through building your own MCP server from scratch, enabling Claude Code to access custom features […]

How to Remove “Hidden Code” from ChatGPT and other LLMs

approximately 800GB of files were deleted, including the entire CursorAI application itself — after executing code generated with assistance from Gemini 3 while working inside the CursorAI IDE. As developers increasingly rely on LLMs for code generation, the consequences of unreviewed or unsafe scripts grow more severe.

Therefore, it is quite important to know how to detect and remove dangerous codes generated by LLM.
