## How they compare

On price, Particle is hard to beat for its niche. It lists GLM 5.3 Flash at $0.10 in and $0.40 out and DeepSeek V4 Flash 0731 at $0.14 in and $0.28 out, with cache reads at $0.03 per million and 1M context across all three models. DeepSeek V4.1 Flash runs about 157 tokens per second, though latency on that listing reaches 3.5 seconds. Workers AI's catalog is wider, with 50+ models including DeepSeek V4 Pro, GLM 5.3 and Kimi K2.7 Code, and also offers 1M context on DeepSeek V4, with prefix caching and session affinity.

Access and track record separate them further. Particle is an early startup still hiring its founding team, reached mainly through Vercel AI Gateway, which makes it easy to try without a new contract and a natural fallback route. Workers AI comes from a company founded in 2009, reached general availability in April 2024, and runs next to Workers, storage and its own AI Gateway. Neither offers fine-tuning for large models. For cheap high-volume Flash calls, Particle leads; for a full app platform, Cloudflare does.

## What each one does

### Cloudflare Workers AI

Workers AI is the serverless GPU inference service of Cloudflare, which was founded in 2009. It launched in September 2023 and reached general availability in April 2024. Models run on GPUs inside Cloudflare's own network and are called from a Worker through an AI binding or over REST, including OpenAI-compatible Chat Completions and Embeddings endpoints plus a Responses endpoint for gpt-oss. The catalog lists 50+ open models. Since Kimi K2.5 arrived in March 2026 it has carried frontier-scale LLMs: Kimi K2.6 and K2.7 Code, GLM 5.2 and 5.3, DeepSeek V4 Pro and Flash, gpt-oss 120B and 20B, Qwen 3.8 27B and Llama 4 Scout. DeepSeek V4, added August 14, 2026, was the first to offer the full 1,048,576 token context.

### Particle.AI

Particle AI is an early San Francisco infrastructure startup with a mission to make intelligence as cheap and abundant as electricity. The team works on post-training, inference optimization and distributed systems, all aimed at pushing down cost per unit of intelligence. It is still hiring its founding team and works fully in person. Public detail about funding and founders is thin as of this writing.
