Cloudflare Workers AI vs StreamLake: key differences

For coding agents, both have a candidate. StreamLake's KAT-Coder-Pro V2.5 is a proprietary model trained with large-scale agentic reinforcement learning for repository-level work, and StreamLake offers a Claude-protocol proxy that drops into Claude Code or OpenClaw alongside OpenAI-protocol endpoints. Developers can pay per token or buy a KwaiKAT Coding Plan. Workers AI answers with open models such as Kimi K2.7 Code, GLM 5.3 and DeepSeek V4 Pro, published at per-token equivalents like $1.32 in and $3.96 out for DeepSeek V4 Pro, and 1M context on DeepSeek V4.

Procurement is likely the deciding factor. StreamLake's pricing and documentation lead with China and yuan, and data residency in China rules it out for many US and EU enterprise buyers, though it suits Chinese internet businesses that want domestic MaaS and bare metal. Workers AI bills in Neurons at $0.011 per 1,000 with a free daily tier, and sits in the same account as Workers, storage and AI Gateway. Neither supports fine-tuning a large model, and StreamLake publishes no context or speed figures for KAT-Coder.

What Cloudflare Workers AI and StreamLake 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 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.

Example models: DeepSeek V4 Pro, GLM 5.3
