# Evaluate Model: Claude Opus 4.6 & Sonnet 4.6: Enhanced Coding and 1M Token Context
## What This Is
Anthropic has released updated Claude models (Opus 4.6 and Sonnet 4.6) with significantly improved coding skills and a massive 1 million token context window. These models can also perform advanced security analysis, finding vulnerabilities better than many traditional tools, and work directly with applications like Excel.

## Before You Start
Scan my workspace and analyze:
- The project language, framework, and current AI integrations
- Existing AI provider config (check .env, .env.local, config files for API keys — OpenRouter, OpenAI, Anthropic, Google AI, etc.)
- Which AI models I currently use and for what purposes
Then ask me before proceeding:
1. Am I interested in evaluating this model for my project, or just want a summary of what it offers?
2. If I want to try it — which part of my current AI stack should it replace or complement?

## What to Implement
This is a **New AI Model** — a model release, update, or capability announcement.
- Analyze the best use cases for this model within my project and current AI stack
- Compare its strengths, pricing, and context window against whatever I currently use
- Give me a clear, convincing argument for why this model would (or would not) be a good fit for my project
- If I want to try it: update my API configuration (provider, model ID, any new parameters) to point to this model
- If it requires a new API key or provider signup, tell me exactly what to do
## Additional Context
- Analyze the enhanced coding, security analysis, and 1M token context window capabilities of the new Opus 4.6 and Sonnet 4.6 models to determine their suitability for the user's project.
- Benchmark the performance and cost of Opus 4.6 and Sonnet 4.6 against the user's currently configured AI model for typical coding and analysis tasks within the project.
- If the user confirms they wish to switch, modify the `CLAUDE.md` or the project's central AI configuration file to specify 'claude-opus-4.6' or 'claude-sonnet-4.6' as the primary model and verify the change is active.
## Guidelines
- Adapt everything to my existing project — do not assume a specific stack or directory layout
- Use whichever AI provider I already have configured; if I need a new one, tell me what to sign up for and I'll give you the key
- Check my .env files for existing API keys (OpenRouter, OpenAI, Anthropic, Google AI) before asking me to add one
- Review any fetched code for safety before installing or executing it
- After setup, run a quick verification and show me a summary of exactly what was installed, where, and how to use it
