Deployment evidence
XHToken · 4B primary; 1.7B official variant total · 4B dense primary active · 1M tokens
Best-fit scenarios
Compact million-token multilingual model family for local agents, coding assistants and edge or desktop deployment.
Not recommended
- Assuming one-million-token context fits a small device because the weights do
- Treating more than 200 supported languages as equal quality in every language
Multilingual local agents
Vendor-statedThe official release advertises support for more than 200 languages and a one-million-token context across the 4B and 1.7B variants.
Capability sourceCoding and tool workflows
Vendor-statedThe vendor positions the family for coding, function calling and agent use across server and local runtimes.
Capability sourceDesktop and edge assistant
ChinaAPI inferenceThe small dense variants and official GGUF, MLX, Ollama and LM Studio paths make local evaluation practical.
Official launch / minimum
Evidence COfficial single device path no vram floor
Official SGLang and local-runtime paths run on one device, but the vendor only says that sufficient memory is required and publishes no absolute VRAM floor for one-million-token context. Primary recipe
200-person team
Evidence EBenchmark required
Benchmark a 4B server worker and the actual language mix; use the 1.7B variant only after task-quality acceptance.
Commercial API
Evidence COfficial framework paths
Official vLLM and SGLang paths exist; production still requires replicas, parser pinning and per-language evaluation. Primary recipe

Known limitations and open questions
- No ChinaAPI reproduction or official absolute hardware minimum
- The one-million-token setting has workload-dependent memory and latency
- Multilingual breadth is a vendor claim and needs target-language validation
