Which open-source AI model should you pick?
DeepSeek V4, Qwen, GLM, and MiniMax occupy the cost-performance side of the model market. DeepSeek should lead this site's narrative because the official V4 rollout turns it into a more current flagship story, while Qwen, GLM, and MiniMax remain useful anchors for multilingual, agentic, and experience-led use cases.
Practical verdict
Default to DeepSeek V4 for coding and reasoning traffic. Pick Qwen 3.5 when multilingual breadth (119+ languages) is the priority, GLM 5 when you need open-weight agentic coding with Chinese-language strength, and MiniMax M2.7 when product interaction quality matters more than raw backend score. Confirm each model's current license on its official model card before you ship on self-hosted weights.

Use-case routing table
| Use case | DeepSeek fit | Alternative fit | Decision note |
|---|---|---|---|
| Coding and reasoning | Best headline fit | Qwen/GLM strong | DeepSeek remains the primary model for this site's SEO and CTA path, now with a more concrete official V4 story. |
| Chinese-language production | Strong | Qwen/GLM strong | Use native-language evals before making a final decision. |
| Agentic tool use | Best default | GLM/Qwen strong | Measure tool-call validity and cost per completed task. |
| Creative user experience | Good | MiniMax strong | Creative continuity and UX quality may matter more than raw code score. |
Open-weight status at a glance
"Open source" means different things per model, so check licenses before you self-host. DeepSeek V4: the V4 Preview was announced as open-sourced, and community GGUF builds of V4 Flash exist for local runs — but most developers still call the hosted API. Qwen 3.5: open-source-oriented, 397B MoE (17B active), 1M context, 119+ languages. GLM 5: Zhipu AI's open-weight flagship, 355B MoE, 200K context, strong agentic coding. MiniMax M2.7: strong for agentic and UX-heavy products, but confirm current weight availability on MiniMax's official model card rather than assuming open weights. Always verify the exact license terms on each provider's official page before shipping on self-hosted weights.
Fastest path: DeepSeek V4 first
For most developers the practical answer is to test DeepSeek V4 first — it has the most current official flagship story (Pro and Flash, 1M context, OpenAI-compatible API) and the lowest-friction hosted path. Reach for Qwen, GLM, or MiniMax only where the workload actually needs their specific strengths. This keeps evaluation cost down instead of benchmarking four self-hosted stacks at once.
Do not confuse comparison coverage with inventory
Open-source and open-weight-oriented models are useful comparison topics, but they do not automatically become purchasable products. Plan listings remain gated by actual resale inventory.
How to keep the comparison useful
Show each model's strengths, link into model detail pages, and avoid declaring a universal winner when the right answer depends on language, workload, latency, and cost. If you plan to run weights locally, pair this with the GGUF and local-deployment guides for hardware requirements.
