	Izlo Agents	Yi (01.AI) Agents
Tagline	Prompt management platform with version control, collaboration, and an API for production deployment.	Foundation models from 01.AI — open-weight Yi family plus frontier Yi-Lightning and Yi-Large
Category	Agents	Agents
Pricing	Paid· Solo $20/mo; Pro $25/user/mo; Enterprise $39/user/mo	Freemium· Open-source Yi models free under permissive license; hosted API via platform.lingyiwanwu.com with pay-per-token pricing (Yi-Lightning positioned as a low-cost frontier tier; Yi-Large priced higher; exact per-token rates on the platform dashboard).

Pros	Git-style version history and activity log for every prompt change Remix sandbox isolates experiments from production prompts REST API lets you swap prompts without redeploying the app Built for multi-user team editing, not just solo developers	Yi-Lightning was the first Chinese LLM to surpass GPT-4o on LMSYS Chatbot Arena, at a fraction of the token cost Open-weight Yi-1.5 (6B/9B/34B) and Yi-VL models under a permissive commercial license make on-prem deployment realistic Yi-Coder covers 52 programming languages and punches above its weight for its parameter count OpenAI-compatible hosted API means minimal code changes to A/B-test against GPT/Claude endpoints Strong bilingual English-Chinese performance, unusual among Western-focused frontier models Full model spectrum (1.5B up to MoE frontier) lets teams pick the right cost/quality point for each task
Cons	No free tier; cheapest plan is $20/mo Stingy token allowance (5K/seat) for in-app testing Lighter on observability/analytics than Langfuse or Helicone Supported model providers not clearly listed on the site	Closed models (Yi-Large, Yi-Lightning) are hosted primarily on Chinese infrastructure; latency and compliance may be issues for Western enterprise buyers English-language docs, community tooling and ecosystem lag significantly behind OpenAI, Anthropic and Meta's Llama Benchmark leadership has been volatile — Chatbot Arena position keeps moving as competitors ship No native agent framework, evals suite, or fine-tuning UI comparable to OpenAI or Google Vertex; you assemble your own stack Data-residency and export-control questions around a China-headquartered vendor are unresolved for many regulated buyers Support and SLA quality for non-Chinese customers is inconsistent versus hyperscaler-backed alternatives
