Pieces Rate Limits

The Pieces OS API is served on-device over the loopback interface (http://localhost:1000) and does not impose conventional per-account HTTP rate limits the way a hosted cloud API would. Throughput for local model inference is bounded by the host machine's CPU, GPU, and memory. Where Copilot requests are routed to cloud models, usage limits follow the account's plan tier (Free has limited cloud usage; Pro is unlimited), and the upstream cloud model provider's own limits apply. Specific numeric limits are not documented for the local API and are not reconciled here.

Pieces Rate Limits is the machine-readable rate-limit profile for Pieces on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring requests and tokens.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include AI, Developer Tools, On-Device, Local API, and Long-Term Memory.

Limits

Local API Requests device
requests
bounded by local hardware
No documented HTTP rate limit; throughput depends on the host machine.
Local Model Inference device
tokens
bounded by local CPU/GPU/memory
On-device LLM throughput is hardware-bound, not quota-bound.
Cloud Model Usage (Free) account
requests
limited (see plan)
Free tier includes limited usage of select cloud models.
Cloud Model Usage (Pro) account
requests
unlimited (per plan)
Pro tier provides unlimited premium cloud model usage; upstream provider limits may still apply.

Policies

On-Device Transport
The API binds to localhost; it is not exposed to the network, so limits are local rather than tenant-based.
Plan-Gated Cloud Usage
Cloud-routed Copilot usage is governed by the account plan (Free limited, Pro unlimited) rather than a documented rate-limit table.
