GLM-5.3-Flash

by 0G Foundation

Zhipu AI GLM-5.3-Flash, a fast, cost-effective model for coding and agentic tasks; served via Tencent Cloud MaaS (TokenHub), which exposes both OpenAI and Anthropic faces. Text in / text out, 1M context, up to 128K output. Deep thinking is always on, controllable via reasoning_effort ("none" disables it); function calling (tool_choice limited to auto/none in thinking mode), JSON mode (response_format: json_object), and implicit prompt caching supported.

Additional Features

TEE Verification

Request on-chain signature verification with verify_tee. The response includes a tee_verified field in the trace.

{
  "model": "glm-5.3-flash",
  "messages": [{"role": "user", "content": "Hello!"}],
  "verify_tee": true
}

Provider Routing

Control which provider handles your request using the X-0G-Provider-* request headers.

X-0G-Provider-Address pins a provider; X-0G-Provider-Identity pins which of its upstreams to route through — both values come from the address and provider_identity fields of GET /v1/providers. Together they address one specific upstream of one provider. Send neither and the router picks by price and health, exactly as before.

curl "https://router-api.0g.ai/v1/chat/completions" \
  -H "Authorization: Bearer <YOUR_API_KEY>" \
  -H "Content-Type: application/json" \
  -H "X-0G-Provider-Address: <PROVIDER_ADDRESS>" \
  -H "X-0G-Provider-Identity: <UPSTREAM>" \
  -H "X-0G-Provider-Sort: latency" \
  -H "X-0G-Provider-Allow-Fallbacks: true" \
  -d '{
    "model": "glm-5.3-flash",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'
