AI infrastructure platform for LLMs and multimodal models.
SiliconFlow is an AI infrastructure platform that provides unified API access to open-source and commercial LLMs and multimodal models, with pricing starting at free tier access and usage-based rates as low as $0.10 per million tokens. It targets developers, AI engineers, and enterprises building production AI applications who need predictable costs and high-speed inference at scale.
The platform operates as a one-stop AI cloud, offering a single API endpoint that routes requests across dozens of text, image, and video generation models including DeepSeek-V3.2, GLM-5.1, Kimi-K2.5, MiniMax-M2.5, and Step-3.5-Flash. Context windows extend up to 262K tokens on models like Step-3.5-Flash and Kimi-K2.5, making it viable for long-document RAG, multi-step agent workflows, and code understanding tasks. Pricing is transparently published per model, with input costs ranging from $0.10/M tokens (Step-3.5-Flash) to $1.40/M tokens (GLM-5.1) and output costs from $0.30/M to $4.40/M tokens — significantly undercutting closed-model providers like OpenAI and Anthropic for equivalent capability tiers.
Based on our analysis of 870+ AI tools in the aitoolsatlas.ai directory, SiliconFlow sits in the inference aggregator niche alongside Together AI, Fireworks AI, Replicate, and OpenRouter. Its differentiation lies in early access to Chinese-origin frontier models (Z.ai's GLM family, DeepSeek, MiniMax, Moonshot AI's Kimi) that often ship weeks before appearing on Western platforms, combined with transparent per-model pricing rather than aggregated credit systems. Common use cases on the platform include agentic systems requiring multi-step reasoning and tool-use, RAG pipelines over long-context knowledge bases, code assistants needing autocomplete and structured edits, and content generation workflows spanning text, image, and video modalities. Compared to the other infrastructure tools in our directory, SiliconFlow is best suited to teams that prioritize model variety and cost transparency over managed fine-tuning or deep MLOps tooling.

A single REST endpoint abstracts over 20+ LLMs and multimodal models from labs including DeepSeek, Z.ai, MiniMax, Moonshot AI, and StepFun. Developers switch models by changing a single identifier in the request body, which simplifies A/B testing, fallback routing, and cost optimization across providers.
Several catalog models expose extended context windows — Step-3.5-Flash and Kimi-K2.5 both reach 262K tokens, while GLM-5.1 and GLM-5 offer 205K. This makes the platform viable for document-heavy RAG, long agent trajectories, and full-codebase reasoning tasks without manual chunking gymnastics.
Every model on the catalog publishes explicit input and output rates in dollars per million tokens, ranging from $0.10/M to $1.40/M on input. Unlike credit-based aggregators, this lets teams model costs precisely before deployment and reconcile usage line by line.
Beyond text chat, the platform hosts vision models (GLM-5V-Turbo, GLM-4.6V), image generation, and video generation endpoints. A single billing account and API key covers the full pipeline, removing the integration overhead of stitching together separate image, video, and text providers.
Models like GLM-5.1 (April 2026), GLM-5V-Turbo (March 2026), and MiniMax-M2.5 (February 2026) appear on SiliconFlow at or near their public release dates. For research teams and startups benchmarking frontier capability against cost, this provides a meaningful lead-time advantage over Western aggregators.
