Gateway request limits

Input limit: 1M
Output limit: 384K

A missing Gateway limit is unpublished, not unlimited. Provider capabilities are not a route acceptance test.

Route acceptance record

2026-10-21

Short checks passed with default reasoning and max_tokens=512 plus max_completion_tokens=512. Streaming included final usage and [DONE]; the tool check included returning a tool result and a final answer. These checks do not validate a full coding agent or the complete 1M context.

Test date	Endpoint	Capability	Route test
2026-10-21	`POST /v1/chat/completions`	Text response	Passed
2026-10-21	`POST /v1/chat/completions`	Reasoning	Passed
2026-10-21	`POST /v1/chat/completions`	Streaming	Passed
2026-10-21	`POST /v1/chat/completions`	JSON mode (json_object)	Passed
2026-10-21	`POST /v1/chat/completions`	Tool calling	Passed
2026-10-21	`POST /v1/chat/completions`	Image input	Check failed

Small acceptance samples on the stated date. Full context and output limits are catalog declarations; long-context quality, complete coding workflows and sustained stability were not established by these checks.

Pricing

Prices in USD per 1M tokens.

Input$0.17

Cache Read$0.005

Cache Write—

Output$0.7

Example task: Extract fields from a document

Assume 12,000 aggregate input tokens and 1,000 billable output tokens across all calls. No cache hit.

12,000 × $0.17 / 1M + 1,000 × $0.7 / 1M = $0.002740

If usage actually reports 9,000 of those input tokens as cached, replace that portion at the cached-input rate ($0.005/1M): $0.001255. Cached tokens are part of total input, never added on top.

Illustrative calculation using the 2026-10-21 catalog snapshot. Include every agent call and retry, repeated history and billable reasoning output; settle against actual usage and current Console prices.

Estimate your monthly cost

Uses the 2026-10-21 catalog snapshot, independently of the live prices above. USD per 1M tokens; an estimate, not a bill.

Estimate includes standard text input, cache reads and text output only. Long-context premiums, service tiers, cache writes, image output and tool fees are excluded.

Model

Total input tokens / request

Billable output tokens / request

Cache-hit tokens / request

Requests / month

Cached share of input

Cache-hit share = cache-hit tokens ÷ total input. Changing total input keeps the current share; dragging the slider updates cache-hit tokens. Output includes billable reasoning. Count agent steps and retries as requests.

Calculation and billing basis

Monthly cost = requests × [input × (1 − cached share) × input rate + input × cached share × cache-read rate + output × output rate] / 1,000,000.

Cached tokens are part of total input, never added on top. Use actual cache-read hits from usage; repeating a prompt does not guarantee a hit. Missing rates are unconfirmed, not $0. Separate cache-write, storage and other additional fees are excluded. Settle against actual usage and current Console prices.

Enable JavaScript to use the calculator. The worked example above remains available.

Usage limits

Use the Gateway request limits above when configuring clients. Official context describes the model capacity, not an account entitlement.
Start with one representative task. Check correctness, actual usage and response time before increasing traffic.

API parameters

Parameter / protocol field	Usage
`model / messages`	Use the exact model ID and chat message list
`tools / tool_calls / tool messages`	Use tools to define functions and role=tool to return their results
`stream / stream_options.include_usage`	Use SSE streaming with final usage
`max_tokens`	Set an output budget within the model and account limits

Parameters vary by model. Keep model-specific controls separate from shared OpenAI-compatible fields.
