Baseten запустила доступ к Kimi K3 через API в день релиза

Kimi K3 launched with day-0 partners including Nebius, Baseten, Fireworks AI, DigitalOcean Serverless Inference, and Together AI, per Moonshot's launch-day announcements. Kimi K3 launched with Max reasoning effort only, then added Standard and High effort levels within roughly a week, per TestingCatalog. Kimi K3 scores 57 on the Artificial Analysis Intelligence Index, ranking fourth behind Claude Opus 5, Claude Fable 5, and GPT-5.6 Sol. Kimi K3 costs roughly $0.94 per Intelligence Index task versus GPT-5.6 Sol at $1.04 despite lower per-token pricing, driven by verbose output, per Artificial Analysis. [...] Kimi K3 is a 2.8T-parameter MoE with 16 of 896 experts active per token and ~2.5× better scaling efficiency than Kimi K2, per Moonshot's official blog. New architecture components: Kimi Delta Attention (KDA), Attention Residuals (AttnRes), and a Stable LatentMoE framework. Open weights shipped July 27, 2026 to Hugging Face — exactly on the date Moonshot committed to at launch.

Kimi K3 is Kimi’s most capable flagship model to date, with 2.8 trillion parameters. It is built on Kimi Delta Attention (KDA), a hybrid linear attention mechanism, and Attention Residuals, with native visual understanding and a 1M-token context window. It is the world’s first open-source model in the 3-trillion-parameter class, designed for frontier intelligence scenarios including long-horizon coding, knowledge work, and reasoning.For complete benchmarks and case studies, see the technical blog. Kimi is currently working closely with inference partners and open-source maintainers to align technical details and ensure the model launches reliably across the ecosystem. The full model weights will be released by July 27, 2026. More details on architecture, training, and evaluation will be [...] A 3-trillion-scale open-source model

## Fireworks AI# Fireworks exposes K3 as `accounts/fireworks/models/kimi-k3`. It supports serverless inference, on-demand dedicated GPUs, image input, function calling, and fine-tuning. The differentiator is operational control. Fireworks says its K3 serverless endpoint is US hosted with zero data retention and offers a path from shared inference into dedicated capacity and tuning. ## Baseten# Baseten's K3 Model API supports image input and the full 1M-token context through an OpenAI-compatible endpoint. Its day-0 article is the clearest infrastructure explanation in this provider set, including validation with the Kimi Vendor Verifier, vLLM, and SGLang.
