Kimi-K2 CLI (CCR + Kimi-K2): I'm REALLY Impressed! I'm switching from Claude Code!

Key Concepts

• Kimmy K2: A new, large, open-weights, non-thinking AI model.
• Open Router: A platform for accessing various AI models through a unified API.
• Open Code: A tool for coding with AI models.
• Claude Code: A tool for coding with AI models, particularly Claude models.
• Claude Code Router (CCR): A tool to route Claude Code requests to other models.
• Ninja Tools: An AI platform offering access to multiple AI models and tools under one subscription.

Kimmy K2 Overview

• Kimmy K2 is highlighted as a significant open-weights model, surpassing Claude Sonnet's non-thinking variant in benchmarks.
• Initially available via the base Kimmy API, it's now also accessible through Open Router.
• Pricing:
  • Kimmy API: $0.60 and $2.50 per million tokens.
  • Open Router: $0.57 and $2.30 per million tokens (slightly cheaper).
• Supported by platforms like Nova and Parasale.
• Currently doesn't support caching on Open Router.
• Available in Klein, Rue, and Kilo (free with $20 credits, no Open Router markup).
• Considered the best open coding model, excelling in coding tasks and integration with Klein and Rode.

Using Kimmy K2 with Claude Code

• The video emphasizes the effectiveness of using Kimmy K2 with Claude Code via Claude Code Router.
• The presenter claims this setup is even better than using Klein, possibly due to system prompts and other factors.

Configuration Steps for Claude Code Router

1. Install Claude Code Router: Use the specified command (e.g., pip install claude-code-router).
2. Configure the Config File:
   • Locate the config file in the home directory.
   • Set up the configuration to use Kimmy K2 via Open Router (using the ki dev model).
3. Run Claude Code with CCR: Use the command CCR code to start Claude Code with Kimmy K2.

Example Usage

• The presenter demonstrates using Kimmy K2 with Claude Code by providing a code base and asking it to add an option to change the theme to light or dark.
• The model successfully creates a to-do list and utilizes tools effectively.
• The presenter finds the performance comparable to or slightly better than Claude Sonnet.

Open Code Integration

• Open Code can be configured to use Kimmy K2, but the Open Router variant of Kimmy K2 currently has issues.
• The official Kimmy API works seamlessly with Open Code.

Configuration Steps for Open Code

1. Install/Update Open Code: Use the specified commands (e.g., pip install opencode or pip install --upgrade opencode).
2. Login to Open Router: Run open code O login and select the Open Router option.
3. Enter API Key: Provide your Open Router API key.
4. Configure Kimmy Provider (Official API):
   • Open the Open Code config file.
   • Create and configure the ki provider.

Ninja Tools Advertisement

• Ninja Tools is presented as an AI platform that combines access to various AI models (Claude, GPT-4, Gemini, etc.) and AI tools (video, image, music generation, document chats) under one subscription.
• Claimed savings of over $600 per year compared to individual subscriptions.
• Pricing starts at $11 per month, including chat messages, image generation, and music generation.
• Coupon code "AI code king 20" provides an additional 20% discount.

Key Arguments and Perspectives

• Kimmy K2 is a highly capable and cost-effective open-weights model, comparable to or even surpassing Claude Sonnet and potentially rivaling GPT-4.
• The combination of Kimmy K2 with Claude Code via Claude Code Router is particularly effective for coding tasks.
• The presenter expresses excitement about the model's potential and its impact on the AI landscape.
• The presenter notes that the model is so good that OpenAI delayed their open model release.

Technical Terms and Concepts

• Open-weights model: An AI model whose weights (parameters) are publicly available.
• Non-thinking variant: A version of a model optimized for speed and cost-effectiveness, potentially sacrificing some reasoning capabilities.
• API (Application Programming Interface): A set of rules and specifications that software programs can follow to communicate with each other.
• Prompt catching: A technique to cache and reuse prompts to reduce API costs and latency.
• System prompt: Instructions given to an AI model to guide its behavior and responses.

Logical Connections

• The video starts by introducing Kimmy K2 and its capabilities.
• It then discusses the availability of Kimmy K2 on Open Router and its pricing.
• The focus shifts to integrating Kimmy K2 with Open Code and Claude Code, highlighting the advantages of the latter.
• The Ninja Tools advertisement is inserted as a relevant resource for accessing multiple AI models.
• The video concludes with a summary of the presenter's positive experiences with Kimmy K2 and a call to action for viewers to try it out.

Synthesis/Conclusion

The video promotes Kimmy K2 as a powerful and affordable open-weights AI model, particularly effective for coding tasks when used with Claude Code via Claude Code Router. It provides practical guidance on configuring these tools and emphasizes the model's potential to rival or even surpass proprietary models like Claude Sonnet and GPT-4. The presenter's enthusiasm and specific examples make a compelling case for exploring Kimmy K2 as a viable alternative for AI-powered coding.
