Bakgrund
Om Genmo
Grundat 2023 · San Francisco, USA
Genmo was founded in 2023 by Paras Jain (CEO) and Ajay Jain (CTO), both PhDs from UC Berkeley's BAIR lab, with a focus on open-source generative video. The company released the early Replay product and the smaller GEN-1 video model before launching Mochi 1 in October 2024 as a 10B-parameter open-weight text-to-video model under the Apache 2.0 licence -- at the time the largest open-source video model with a fully permissive licence. Genmo positions Mochi 1 as a research foundation for the community to fine-tune, extend and study, in deliberate contrast to closed competitors. The company has raised over $30M from investors including NEA and the Y Combinator network.
Asymmetric Diffusion Transformer (AsymmDiT) at 10B parameters with custom 3D VAE
Mochi 1 is a 10B-parameter Asymmetric Diffusion Transformer (AsymmDiT) operating on a high-compression 3D causal Variational Autoencoder. The 'asymmetric' design uses dramatically more parameters for the video stream than for the text stream while sharing self-attention, on the hypothesis that visual modeling is the bottleneck for video generation. Position information uses 3D RoPE; the model is trained with Rectified Flow Matching at full resolution and high motion intensity. Text conditioning uses a T5-XXL encoder. Mochi 1 generates 5-second clips at 480p / 30 fps natively (with a 720p HD variant in preview at launch). Training is done on a curated, filtered video corpus with dense captions produced by an in-house captioner. The team explicitly report ablations on resolution scheduling, motion intensity filtering and caption quality.

Vad kostar Mochi 1 på Railwail?
På Railwail kostar Mochi 1 ≈ 0,5041 US$ per körning. Du debiteras för det som varje begäran faktiskt använder. Användningen betalas från förbetald kredit; 1 kredit motsvarar 0,01 US$.
Vilka inställningar stöder Mochi 1?
Enligt sitt inmatningsschema känner Mochi 1 till dessa parametrar: prompt (upp till 2 000 tecken), fps (8 till 30), seed, aspect_ratio (16:9, 9:16 eller 1:1), duration_sec (1 till 6) och motion_strength (0 till 1).
Hur snabb är Mochi 1?
Det finns ännu inte tillräckligt många uppmätta körningar av Mochi 1 på Railwail för att ange en körningstid. Det beror på inmatningen, inställningarna och belastningen hos leverantören.
Är Mochi 1 bättre än Google Veo 3.1?
Det beror på uppgiften. Mochi 1 (Community) och Google Veo 3.1 (Google DeepMind) är båda modeller i kategorin Videogenerering. Jämförelsesidan visar deras priser och specifikationer sida vid sida.
