DeepSeek
- +Free consumer chat assistant and a notably low-cost API versus US frontier providers
- +Open-weight models under the MIT license, so they can be self-hosted, fine-tuned, and run by third parties
- +OpenAI- and Anthropic-compatible API makes it a near drop-in for existing apps and coding tools
- -It is an assistant, not an autonomous agent: it responds when asked and does not act end-to-end
- -China-hosted service raises data-residency and privacy concerns, and the app has faced government bans and scrutiny in several countries
Qwen
- +Strong open-weight models (many under Apache 2.0) that can be self-hosted, plus a free consumer chat
- +Broad multimodal coverage: text, code, image, video, audio, and an omnimodal model
- +Pay-per-token API via Alibaba Cloud Model Studio for the flagship and hosted models
- -Core Qwen Chat is an assistant, not an autonomous agent; only DeepResearch and Qwen Code are more agentic, under user oversight
- -Licensing is mixed (Apache 2.0, source-available Qwen License, non-commercial Qwen Research License), so terms vary by model
