Cosine raises $2.5 million and unveils advanced AI developer genie

London-based startup Cosine has successfully raised $2.5 million in funding. The investment round was spearheaded by prominent US venture firms Uphonest, known for backing Sending Labs, and SOMA Capital.

They were joined by notable investors Lakestar, which has previously supported Isar Aerospace and Firenze, as well as Focal and other key players in the venture capital sphere.

Cosine, founded in 2022, has made waves with its innovative approach to artificial intelligence.

The company’s latest announcement is a groundbreaking leap in AI-assisted software development, introducing their artificial developer, Genie.

This development promises to redefine how software is created and maintained by mimicking the reasoning and problem-solving skills of human developers.

The brainchild of Cosine’s founders—Alistair Pullen, Sam Stenner, and Yang Li—the company emerged from their collective vision of harnessing large language models (LLMs) to handle complex coding tasks.

Their goal is ambitious: to build an AI that can tackle open-ended problems across various domains with resilience and adaptability.

Cosine’s headquarters in London positions it at the cutting edge of AI technology. The startup is a notable participant in Y Combinator’s accelerator program, and their flagship product, Genie, is designed to function as an advanced, autonomous software developer.

Genie can autonomously resolve bugs, build features, refactor code, and collaborate with human developers, all while handling queries and providing explanations in plain English.

In a notable achievement, Cosine recently reported that Genie scored a remarkable 30% on SWE-Bench, the industry’s leading benchmark for evaluating AI software engineering skills.

This score not only surpasses the previous best of 19% held by Factory but also represents a staggering 2,196% improvement over OpenAI’s GPT-4, which scored just 1.31%.

This impressive feat underscores Cosine’s significant advancement in the field, demonstrating their AI’s superior ability to understand, modify, and generate complex code.

“Our breakthrough in codifying human reasoning is allowing us to train AI models to operate far beyond the narrow tasks typically associated with software development,” remarked Alistair Pullen, Cosine’s CEO.

Pullen, who was notably a software entrepreneur from a young age, emphasized that Cosine’s technology offers a transformative approach to development, potentially outpacing competitors in both efficiency and cost-effectiveness.

Yang Li, the company’s COO, highlighted the implications of their advancements: “We’ve developed a product capable of surpassing established AI models in completing complex software tasks swiftly and economically. Our aim is to revolutionize how development and developers operate.”

Sam Stenner, Cosine’s CIO, added a crucial perspective on the company’s philosophy: “Our focus is on creating a colleague, not just a co-pilot.

By generating datasets that capture human reasoning, and working with OpenAI to fine-tune their largest context window LLMs, we are confident in our ability to consistently exceed our top scores.”

The enthusiasm surrounding Cosine’s progress is echoed by its investors.

Ellen Ma, a Partner at Uphonest Capital, praised the company’s innovative approach: “Cosine is not just improving AI; they’re fundamentally teaching it to reason, providing companies with a true AI colleague.”

Ben Tossell, Founder of Ben’s Bites, also lauded the company’s accomplishments: “Genie is proof that their vision, strategy, and team are perfectly aligned to bring us closer to achieving Artificial General Intelligence (AGI).”
