Machine translation and GenAI localization for enterprise language teams
Manage stock engines and your own custom models from one console, then push them into the linguistic tools your team already works in.
Compare DeepL, Google, GPT-class and custom models with BLEU, WER and COMET scores plus sample segments to find the best engine per language pair.
Fine-tune translation models on your terminology, style guides and past translations to cut edit distance and post-editing cost.
Plugins and extensions for Trados, Smartling, memoQ, XTM Cloud, Smartcat and Shopware keep MT inside existing localization workflows.
High-efficiency open-weight and hosted reasoning AI powered by DeepSeek-V4 and R1 at ultra-low token costs.
Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
