About

Seed Diffusion Preview is a large-scale, code-focused language model that uses discrete-state diffusion to generate code non-sequentially, achieving dramatically faster inference without sacrificing quality by decoupling generation from the token-by-token bottleneck of autoregressive models. It combines a two-stage curriculum, mask-based corruption followed by edit-based augmentation, to robustly train a standard dense Transformer, striking a balance between speed and accuracy and avoiding shortcuts like carry-over unmasking to preserve principled density estimation. The model delivers an inference speed of 2,146 tokens/sec on H20 GPUs, outperforming contemporary diffusion baselines while matching or exceeding their accuracy on standard code benchmarks, including editing tasks, thereby establishing a new speed-quality Pareto frontier and demonstrating discrete diffusion’s practical viability for real-world code generation.

About

Mercury 3 is a hosted generative AI model from Inception for developers building interactive applications. It uses a diffusion-based approach to generate text in parallel and supports streaming responses, tool use, structured outputs, and multimodal input including text, images, and audio. Through the Inception API, teams can use it for conversational assistants, voice applications, search and browsing workflows, tutoring, and other agentic tasks that benefit from responsive generation. The model is available through Inception’s API and named inference partners, with OpenAI-compatible API access for existing applications. Developers can evaluate output quality and latency, then integrate the model into their software using the documented API and SDK ecosystem. Usage is token-metered, with a free allocation and paid input/output token rates; enterprise options include dedicated capacity and support.
