| Embeddings | Multilingual embedding options are live for RAG |
| Pricing | Flat monthly self-serve plans with unlimited fair-use usage |

TL;DR
- Qwen competes on multilingual quality and open weights.
- Plugsky adds catalogue breadth, flat pricing and residency options.
- Multilingual quality must be tested per language, not assumed.
- Use multilingual embeddings for retrieval in non-English products.
- Hybrid routing works: Qwen where weights matter, Plugsky for general traffic.
How it works, step by step
- List the languages and scripts your product actually serves.
- Build an evaluation set per language with native-speaker review where possible.
- Test Plugsky chat and multilingual embeddings on that set.
- Compare retrieval quality with your existing embedding model before re-indexing.
- Move non-Qwen-specific traffic first, canary, then expand.
- Check residency requirements against available regions and private deployments.

What Qwen users value
Qwen earned adoption through capable multilingual models and open-weight releases, which make the family portable across platforms. The API is OpenAI-compatible, so integration is familiar and frameworks work without custom clients.
The constraints are familiar too: one family, one vendor's pricing curve and a set of regions that may not match every buyer's residency requirements. As products grow into new markets, those constraints become more visible.
Multilingual evaluation and embeddings
Language quality varies by model and task, even within a strong family. Build evaluation sets per language and script, including code-switching if your users mix languages, and score generation and retrieval separately.
- Use multilingual embeddings for retrieval in mixed-language corpora.
- Evaluate named-entity handling, numerals and date formats per locale.
- Check tokenisation effects on cost for non-Latin scripts.
- Keep native-speaker review in the loop for high-stakes content.
- Test transliteration and romanisation for search and retrieval.
- Verify safety and refusal behaviour per locale, not just in English.
Migration, residency and gaps
Plugsky is OpenAI-compatible, so client code moves with a base URL and model-name change. It does not serve Qwen weights by name; choose the closest tier in the 30+ model catalogue and validate per language. Deployment options include region selection, VPC, on-prem and air-gapped environments for residency-sensitive products.
Audio, images, moderation, files, batch, fine-tuning, assistants and responses are coming soon; chat, streaming, tools, embeddings, RAG and agents are live. Run the same evaluation again after any model change, because routing decisions age quickly. Start free, use the 14-day full-access trial for hard prompts, and see the live pricing page for current plans.

Frequently asked questions
Does Plugsky serve Qwen models?
No. Plugsky runs its own curated catalogue of 30+ models. Evaluate the closest tier on your languages and tasks rather than assuming weight-level parity.
Can I migrate without rewriting code?
If your client uses the OpenAI schema, changing the base URL and model names is usually enough. Qwen-specific SDK paths need an adapter.
Is there a free plan?
Yes. plugsky-micro and plugsky-lite are free with no credit card, and a 14-day full-access trial opens stronger models.
How is pricing structured?
Self-serve plans are flat monthly with unlimited fair-use usage and no per-token billing. See the live pricing page for current plans.
How should I evaluate multilingual quality?
Build per-language evaluation sets, include code-switching if users mix languages, and score generation and retrieval separately with native-speaker review where stakes are high.
Does Plugsky support multilingual embeddings?
Yes, multilingual embedding options are live and suitable for RAG over mixed-language corpora. Re-embed and compare before switching a production index.
