This article covers two key changes to reasoning control in Claude Opus 4.7, along with complete usage instructions for both the AIHubmix native API and the Chat unified interface. See also: Anthropic official announcement and model change log.
1. New Reasoning Control Features
✦ New xhigh Reasoning Effort Level
The new xhigh level sits between high and max, designed specifically for coding and agentic tasks, striking a better balance between capability and efficiency.
low ── medium ── high ── xhigh ★NEW ── max
✦ Thinking Content Hidden by Default
In streaming responses, the thinking process is no longer shown by default. To receive a reasoning summary, explicitly pass the display field in your request:
| display value | Opus 4.7 | Opus 4.6 | Behavior |
|---|
| ”omitted” | Default | Non-default | Thinking block content is empty |
| ”summarized” | Must set manually | Default | Returns thinking summary text |
"reasoning": {
"effort": "xhigh",
"display": "summarized"
}

2. Claude Native API Reference
| effort value | Modelos Suportados | Description | Recommended Use Case |
|---|
| low | All supported models | Significant token savings with moderate capability trade-off | Simple tasks, high-concurrency requests, sub-agents |
| medium | All supported models | Balanced mode with moderate token savings | General agentic tasks |
| high | All supported models | Default; high capability performance | Complex reasoning, coding, agentic tasks |
| xhigh (new) | Opus 4.7 only | Extended capability between high and max; excels at long-horizon tasks | Recommended starting point for coding and agentic tasks |
| max | Opus series | Maximum capability | Frontier research problems |
AIHubmix Claude Native API — Opus 4.7 Example
from anthropic import Anthropic
client = Anthropic(
api_key="<AIHUBMIX_API_KEY>",
base_url="https://aihubmix.com"
)
response = client.messages.create(
model="claude-opus-4-7",
max_tokens=16000,
thinking={"type": "adaptive"},
output_config={"effort": "xhigh"}, # Options: low / medium / high / xhigh / max
messages=[
{
"role": "user",
"content": "A snail is at the bottom of a 10-meter well. Each day it climbs 3 meters, but each night it slides back 2 meters. How many days does it take to reach the top?"
}
]
)
print(response.content[-1].text)
3. Reasoning Effort Support no AIHubmix Chat Unified Interface
The AIHubMix Chat unified interface aligns com o OpenAI specification and controls reasoning intensity via reasoning.effort. Different Claude models are automatically mapped to the corresponding effort level:
reasoning_effort (Reasoning Intensity Control) for Claude Models
| effort value | Opus >=4.7 (new) | Opus 4.6 / 4.5 | Sonnet 4.6 |
|---|
| minimal | low | low | low |
| medium | medium | medium | medium |
| high | high | high | high |
| xhigh | xhigh | max | high |
| max | max | max | high |
xhigh is natively supported only on Opus 4.7. Other Opus models automatically fall back to max, and the Sonnet series falls back to high.
Chat Unified Interface — Opus 4.7 Example
from openai import OpenAI
client = OpenAI(
base_url="https://aihubmix.com/v1",
api_key="<AIHUBMIX_API_KEY>",
)
completion = client.chat.completions.create(
model="claude-opus-4-7",
# max_tokens=10000, # Default is 4096; enable for longer outputs
messages=[
{
"role": "user",
"content": "A snail is at the bottom of a 10-meter well. Each day it climbs 3 meters, but each night it slides back 2 meters. How many days does it take to reach the top?"
}
],
extra_body={
"reasoning": {"effort": "xhigh"}
}
)
print(completion.choices[0].message.content)
4. Controlling Thinking Content no Chat Unified Interface
Não OpenAI-compatible interface, reasoning suporta a display field to control whether thinking summaries are returned.
Claude Opus 4.7 does not return thinking content by default. Set "display": "summarized" to enable it.
| Field | Value | Description |
|---|
display | (omitted) | Thinking content not returned (default) |
display | "summarized" | Returns a thinking summary |
Opus 4.7 — Thinking Summary Example
from openai import OpenAI
client = OpenAI(
base_url="https://aihubmix.com/v1",
api_key="<AIHUBMIX_API_KEY>",
)
completion = client.chat.completions.create(
model="claude-opus-4-7",
messages=[
{
"role": "user",
"content": "A snail is at the bottom of a 10-meter well. Each day it climbs 3 meters, but each night it slides back 2 meters. How many days does it take to reach the top?"
}
],
extra_body={
"reasoning": {"effort": "xhigh", "display": "summarized"}
}
)
print(completion.choices[0].message.content)
