Anthropic: Claude Haiku 5.5
Anthropic Claude Haiku 5.5 API pricing
Claude Haiku 5.5 costs $0.040 per million input tokens and $0.200 per million output tokens on Oxyy. These are the pay-as-you-go prices after the current 60% discount (Launch Promo; standard price $0.100 input and $0.500 output), and cached input tokens are billed at $0.004 per million. It accepts text and images and returns text, with a 1M-token context window and up to 128K output tokens per response. It is the lowest-priced Anthropic text model on Oxyy; for every model and rate, see Claude API pricing.
Anthropic's fastest model, for high-volume latency-sensitive work: classification, routing, extraction and subagent tasks. 1M context with adaptive thinking.
Providers
Where this model runs, and what each route costs. Requests are sent to a healthy provider automatically; if one errors, the gateway retries against another serving the same model.
| Provider | Input /M | Output /M | Cache read /M | Latency | Throughput |

A parameter not listed here may be removed before the request reaches the model. When it is, the request still succeeds and the response names it, with the reason, in provider_specific_fields.dropped_params.
Pricing
What this model costs on Oxyy, pay as you go. "Charged" is the rate a request is billed at; the standard price is shown beside it for reference.
| Rate | Standard price | Charged | Unit |
|---|---|---|---|
| Input | $0.100 | $0.040 | per 1M input tokens |
| Output | $0.500 | $0.200 | per 1M output tokens |
| Cached input | $0.010 | $0.004 | per 1M cached input tokens |
| Cache write (5 min) | $0.125 | $0.050 | per 1M cache-write tokens, 5-minute |
| Cache write (1 hour) | $0.200 | $0.080 | per 1M cache-write tokens, 1-hour |
Discount. Charged rates include the current "Launch Promo" discount of 60% on every rate.
Long-context pricing. Once the prompt is larger than the threshold, the whole request is billed at these charged rates per 1M tokens; rates not listed keep the price above.Above 100,000 tokens in the prompt: input $0.200 / output $1.00 / cache read $0.020 / cache write $0.250 / cache write (1h) $0.400.

Quickstart
Call claude-haiku-5-5 with a POST to /v1/chat/completions on https://api.oxyy.ai, using your Oxyy API key from the OXYY_API_KEY environment variable. The same key works for every model in the catalog.
import os
from openai import OpenAI
client = OpenAI(
base_url="https://api.oxyy.ai/v1",
api_key=os.environ["OXYY_API_KEY"],
)
response = client.chat.completions.create(
model="claude-haiku-5-5",
messages=[
{"role": "user", "content": "Explain unified AI APIs in one sentence."},
],
)
print(response.choices[0].message.content)Performance
Throughput is how fast the model writes (tokens per second — higher is better). Latency is total round-trip time (lower is better). TTFT is time-to-first-token — how long before you see anything appear (lower is better). Throughput and TTFT are measured on streaming requests, which are the only ones with a first-token moment to time.

Availability
The share of requests to this model that completed successfully over the last 30 days. Requests the caller cancelled, and requests still in flight, are not counted. When an upstream provider errors, the gateway retries against another provider serving the same model, so a single provider incident does not necessarily show up here.
Days are UTC days. Days with no completed requests are omitted rather than drawn at 100% — no traffic is not evidence of availability.
Activity
Token volume and request traffic to this model over time. Daily totals, UTC.
Prompt tokens measure input size. Reasoning tokens show internal thinking before a response. They are part of the output, so the completion bars show the rest of it and each day’s bar is its total.
