From prompt engineering to machine learning security, we break down the vendors helping enterprises deploy large language models.
The launch of OpenAI’s ChatGPT sparked an unprecedented surge of corporate interest in large language models (LLMs).
Big tech companies and research institutes are democratizing access to LLMs, enabling enterprises to more easily take advantage of deep learning capabilities. As enterprises adopt these models, they are focused on improving their data infrastructure, fine-tuning models for specific use cases, and monitoring LLMs for hallucination and bias.
As a result, tech vendors supporting large language model operations (LLMOps) — the end-to-end workflow that organizations employ to build, fine-tune, and deploy LLMs into production — are gaining traction.
In the market map below, we identify 90+ companies across 12 different categories helping enterprises bring LLM projects from start to finish.
Note: Our map includes public, private, and recently exited companies in LLMOps. This market map is not exhaustive of the space.
