What is GPT-5.1 Pro? A professional explainer and status report

OpenAI’s GPT-5.1 Pro is the latest incremental release in the GPT-5 family: a production-grade model update that refines reasoning, latency/throughput tradeoffs, and developer-facing features (especially for code and long-horizon agent tasks). The improvements in GPT-5 Pro are significant for GPT-5, but how does the performance of GPT 5.1 Pro compare? This article will provide a […]

Google Antigravity vs Cursor 2.0: Which IDE should you choose in 2025?

In late 2025 the AI-assisted development landscape took another big step: Google launched Antigravity, an “agent-first” development platform built around Gemini 3 Pro, and Cursor shipped Cursor 2.0 with its Composer model and a new multi-agent interface. Both promise to change how software teams build software with AI — but they take different design decisions, […]

How to Use Flux.2 API? All You Need to Know

FLUX.2 is Black Forest Labs’ second-generation family of image-generation and image-editing models (released Nov 25, 2025). It offers production-grade photorealism, multi-reference editing up to 4MP, structured/JSON prompting, and a choice of managed endpoints (Pro, Flex) and open-weight options (Dev). The good news is that CometAPI has integrated the Flux.2 API. This guide explains what FLUX.2 […]

What is Flux.2 and Flux 2 is now available on CometAPI

FLUX.2 is a newly announced family of image-generation and editing models from Black Forest Labs that offer production-grade fidelity, multi-reference editing (up to 10 references), and deployable variants ranging from open-weight Dev to production Pro and a controllable Flex tier. What is FLUX.2? FLUX.2 is Black Forest Labs’ production-grade image generation + editing family that […]

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 […]

How to Use Claude Opus 4.5 API

Anthropic released Claude Opus 4.5 in late November 2025 as a more capable, more efficient Opus-class model targeted at professional software engineering, agentic workflows, and long-horizon tasks. It’s available through Anthropic’s developer platform and via CometAPI and it introduces new API controls (notably the effort parameter), improved computer-use tooling, extended thinking, and token efficiency improvements […]

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 […]
