Timeline (last 90 days)
On October 6, 2026, Fireworks AI discovered unauthorized use of internal credentials; its security advisory states that a third party accessed environment variables used in evaluation tasks, involving a limited number of customer accounts.
Fireworks AI began notifying affected parties on October 7, rotated employee API keys on October 9, and revoked more user keys and rotated service account tokens on October 10.
The default models of multiple Providers have changed: Cortecs, CrossModel, Eden AI, Google Gemini, GitHub Copilot, Google Vertex AI, LLM Gateway, Ofox, OpenCode Go, and Prime Inference now default to Gemini 4 Argon; Fireworks AI, Nebius Token Factory, and Requesty switch to Muse Spark Open; CoreWeave, DigitalOcean, NanoGPT, and Nvidia adopt Nemotron 3.5 Super VL; Aixy and Neon use Claude Haiku 5.5; Agnes AI, Ambient, IteraCompute, Poe, Scaleway, and SenseNova also have their own adjustments.
Muse Spark Open can be called on the day of release through platforms such as Baseten, Fireworks AI, Groq, Modal, Nebius, OpenRouter and Together AI.
GPU rental costs rose in Q3: RunPod raised its Secure Cloud rate to $3.49 per hour for H100 SXM; Nebius announced an increase for the H100 from $3.85 to $4.50 per hour (effective October 1); Fireworks AI raised the U.S. region serverless premium from 10% to 50%.
Fireworks Forge is Fireworks AI's series of offline event brand targeting the developer community.
Fireworks AI was founded in 2022.
The security incident affected a limited subset of customers rather than all users.
The company officially characterized the incident as access to certain platform features, rather than describing it directly as a large-scale data breach.
Fireworks is an AI model inference and deployment platform for developers and enterprises, providing services such as large language model hosting and API calls.
