## Zhipu BigModel Open Platform (bigmodel.cn)

- `inference/zhipu-bigmodel-open-platform` | qualifies-with-caveat | evidence documented | binding request-rate | category inference API, free models
- needs card no, phone yes, ID no, institution no | verified 2026-11-03T11:30:44.393Z (live) | stale on 2026-12-04
- url https://bigmodel.cn/pricing
- free tier: Two models are free on input, output and cache, with no token cap or expiry stated: the text model GLM-4.7-Flash (200K context) and the vision model GLM-4.6V-Flash. Concurrency per model is the only published constraint and the per-model figure sits behind a login | unit: unlimited | metered on: none | read on: 2026-10-28 | source: [1] | note: perpetual free models; the login page advertises a new-user experience pack of 20 million tokens (2000万); its model scope, expiry and any real-name condition are unverified: behind a…
- per-object cap: not applicable
- retention: not applicable
- egress: metered: no
- identity: any-phone | detail: registration accepts a non-mainland phone number: choose the country code and verify by SMS code. The FAQ states API calls do not require real-name authentication (it is recommended for account security, and is the route to an enterprise account); whether the API-key page asks for it is unverified: behind a sign-up
- interface: rest
- limits:
  - request-rate (binding): concurrency, the number of requests in flight at one moment, is capped per model and per user-rights tier (levels V0 to V3, raised by points that only cash-balance spending earns); the per-model figure for the free text model is on a login-gated page and is unverified [2]
- binding note: concurrency per model and per user-rights tier; platform-level throttling can apply at peak load
- tooling: not stated
- composes with: a free 200K-context text model and a free vision model are a zero-cost first pass in a two-stage pipeline; only the survivors go to a metered model
- reliability: not assessed: no request was sent to the endpoint
- notes: the international Z.ai site publishes its own free Flash models under a separate account system; this is the bigmodel.cn side
- evidence note: the free-model list is the pricing page's own FAQ answer and the authentication FAQ says API calls do not require real-name authentication; the per-model concurrency figure and the terms of the new-user pack are unverified: behind a sign-up

## Zhipu Z Managed Agents

- `compute/zhipu` | paid-only | evidence documented | binding retention-clamped | category container and VM sandbox
- identity a placeholder: card and phone unknown | verified 2026-10-22T04:48:26.000Z (live) | stale on 2026-11-22
- url https://docs.bigmodel.cn/cn/managed-agents/overview.md
- free tier: no free tier published: a managed-agent platform whose sessions emit an idle status when a round ends, with memory mountable across several sessions and cron creating new ones | unit: none | metered on: none | read on: 2026-10-22 | source: [1]
- per-object cap: not stated | source: [1]
- retention: not stated | source: [1] | note: not stated
- egress: not stated | metered: no | source: [1]
- identity: email
- interface: unknown
- limits:
  - retention-clamped (binding): a session emits status_idle when a round ends, so the platform knows when to stop; cron creates a new session on schedule [1]
  - per-object-cap: Memory mounts into several sessions and its changes are audited [1]
  - write-gated: no plan or price appears on the overview; billing is on a page this record does not cite [1]
- limits note: not stated
- tooling: the same as limits note
- composes with: the same as limits note
- reliability: no reliability event recorded
- evidence note: the managed-agents overview was read on 2026-10-22 (Chinese) and documents the session lifecycle and the shared memory, with no plan or price in it. The billing page is not cited by this record, so no figure is asserted
- extras:
  - keep_rate_basis: no field in the source
  - billing_model: unclassified
  - session_cap.restart_required: no
  - session_cap.note: the platform emits session.status_idle at the end of a round, which is the signal a client can bill or stop on
  - free_tier_kind: none
  - reclassified_from: dead
  - ps.price: not stated on the overview
  - ps.durability: Memory mountable across sessions with audited changes
  - ps.on_stop: yes
  - ps.on_destroy: no
  - ps.retention: while the memory is kept
- evidence:
  - [1] 2026-10-02: 
  - [1] 2026-10-22: '平台驱动循环；一轮结束后发出 session.status_idle' - the platform drives the loop and emits session.status_idle when a round ends - and 'Memory 可挂载到多个会话并审计变更；定时任务按 cron 自动创建新会话', quoted
