Cloudflare Workers AI vs Boundless: key differences

Workers AI bills in Neurons with 10,000 free a day and runs 50+ open models on GPUs inside Cloudflare's network, called from a Worker or over OpenAI compatible REST. It prices DeepSeek V4 Pro at $1.32 in and $3.96 out per million tokens, GLM 5.3 at $1.40 and $4.40, and Kimi K3 at $3 and $15. Boundless lists all three for less, with DeepSeek V4 Pro at $1.04 and $2.08, GLM-5.3 at $1.12 and $3.52 and Kimi K3 at $2.30 and $11.40, each with 1M context. Its API works with OpenAI and Anthropic SDKs, keeps zero data retention and also resells GPT and Claude models.

Workers AI is the pick for agents built on Workers, where inference, code, storage and the Agents SDK share one platform, and for bring-your-own LoRA on smaller models. Its large models need the Workers Paid plan or prepaid AI Gateway credits, and synchronous requests can queue for capacity. Boundless fits teams that want lower prices on those same large models, or a reserved deployment that its engineers tune and run against uptime, throughput and latency targets in the contract.

What Cloudflare Workers AI and Boundless do

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 K3, K2.6 and K2.7 Code, GLM 5.2, 5.3 and 5.3 Flash, 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, and Kimi K3 now matches it.

Example models: DeepSeek V4 Pro, GLM 5.3

Boundless

Boundless launched in September 2026 as an inference partner for AI-native startups. It sells two things. The Model API serves pre-tuned models on shared capacity, billed per token from prepaid credits with a budget per API key. Tailored inference reserves capacity for one customer, and Boundless engineers pick the model on the customer’s own evals, tune precision, batching, caching, speculative decoding and parallelism, then run the deployment against uptime, throughput and latency targets written into the contract. A free two-week evaluation tests those targets on real traffic against the customer’s current provider first.

Example models: GLM-5.3, DeepSeek V4.1 Flash, Kimi K3
