‘Arch-Function’ AI models are purpose-built for lightning fast agentic AI

Revolutionizing enterprise AI with Arch-Function LLMs: Katanemo’s open-source release of Arch-Function large language models (LLMs) promises to significantly accelerate agentic AI applications for complex enterprise workflows.

The big picture: Arch-Function LLMs, built on Qwen 2.5 with 3B and 7B parameters, offer ultra-fast speeds for function-calling tasks critical to agentic workflows, potentially outperforming industry leaders like OpenAI’s GPT-4 and Anthropic’s models.

• Katanemo claims Arch-Function models are nearly 12 times faster than GPT-4 while delivering significant cost savings.
• The open-source release aims to enable super-responsive agents capable of handling domain-specific use cases without excessive costs for businesses.
• Gartner predicts that by 2028, 33% of enterprise software tools will use agentic AI, up from less than 1% currently, enabling 15% of day-to-day work decisions to be made autonomously.

Key features and capabilities: Arch-Function LLMs are designed to excel at function calls, allowing them to interact with external tools and systems for performing digital tasks and accessing up-to-date information.

• The models can understand complex function signatures, identify required parameters, and produce accurate function call outputs.
• This capability enables the execution of various tasks, from API interactions to automated backend workflows, facilitating the development of agentic applications.
• Arch-Function analyzes prompts, extracts critical information, engages in lightweight conversations to gather missing parameters, and makes API calls, allowing developers to focus on writing business logic.

Performance and cost advantages: Katanemo’s Arch-Function LLMs demonstrate significant improvements in both speed and cost-effectiveness compared to leading models in the market.

• Arch-Function-3B reportedly delivers approximately 12x throughput improvement and 44x cost savings compared to GPT-4.
• Similar performance gains were observed against GPT-4o and Claude 3.5 Sonnet.
• These benchmarks were achieved using an L40S Nvidia GPU to host the 3B parameter model, which is a more cost-effective option compared to the standard V100 or A100 GPUs typically used for LLM benchmarking.

Potential applications and market impact: The high-throughput performance and low costs of Arch-Function LLMs make them suitable for real-time, production use cases in various industries.

• Potential applications include processing incoming data for campaign optimization and sending automated emails to clients.
• The global market for AI agents is expected to grow at a CAGR of nearly 45% to become a $47 billion opportunity by 2030, according to Markets and Markets.
• Enterprises can leverage these models to build fast, secure, and personalized generative AI applications at scale.

Broader context: Arch-Function is part of Katanemo’s larger ecosystem of AI infrastructure tools, building upon their previous release of the Arch intelligent prompt gateway.

• Arch, open-sourced a week prior, uses specialized sub-billion parameter LLMs to handle critical tasks related to prompt processing and management.
• The combination of Arch and Arch-Function aims to provide a comprehensive solution for developers looking to build efficient and secure AI-native applications.

Looking ahead: While Arch-Function LLMs show promise in benchmarks, real-world adoption and case studies will be crucial in determining their impact on the enterprise AI landscape.

• The open-source nature of these models may accelerate adoption and foster innovation in the agentic AI space.
• As enterprises increasingly seek to integrate AI into their workflows, solutions like Arch-Function could play a pivotal role in making advanced AI capabilities more accessible and cost-effective.
