Celeris-1 is the debut model of Celeris Labs (founded by Tom Hamer and Jesse Clark, previously Marqo), announced on July 22/27, 2026. Unlike conventional autoregressive LLMs, it uses a diffusion architecture that generates multiple tokens in parallel, delivering near-GPT-5-level intelligence with up to 15x faster response times according to the vendor. It is accessible via an OpenAI-compatible API, is proprietary (weights not open), has a combined prompt+completion context window of 131,072 tokens, and scores 75.9% on MMLU-Pro at a p50 latency of 158ms and roughly 1,600-2,000 output tokens per second.
