Create Chat Completion

POST /v1/chat/completions

Request Body

string

required

Model to use for completion (e.g., gpt-4o, gpt-5.1, claude-sonnet-4-6, deepseek-r1). Append :reasoning-exclude to disable reasoning output for a single request.

array

required

Array of message objects forming the conversation.

integer

Maximum number of tokens to generate. Reasoning tokens are billed as output tokens and counted against this limit.

number

Sampling temperature between 0 and 2.

boolean

Enable streaming responses (SSE).

string

Controls reasoning depth on supported models. One of none, minimal, low, medium, high, xhigh. Silently ignored for models that don’t support reasoning_effort.

object

Reasoning configuration object. Supports:

reasoning.effort — same enum as reasoning_effort.
reasoning.exclude (boolean) — strip reasoning from the response entirely.
reasoning.delta_field — "reasoning" or "reasoning_content"; overrides the streaming/non-streaming field name regardless of which endpoint variant was hit.

string

Shorthand for reasoning.delta_field. Accepts "reasoning" or "reasoning_content".

boolean

Shorthand: set to true to force the legacy reasoning_content field, equivalent to reasoning.delta_field = "reasoning_content".

Endpoint Variants (Reasoning Output)

Some models emit a separate reasoning / thinking stream in addition to the final answer. Three base paths control how that stream is surfaced — all of them accept the same request shape and model names.

Base path	Behavior	Use when
`POST /v1/chat/completions`	Reasoning and answer are returned as separate fields (`reasoning` + `content`). Default.	Most OpenAI-compatible clients.
`POST /v1legacy/chat/completions`	Same as `/v1/`, but reasoning uses the legacy field name `reasoning_content`.	Clients that only parse `reasoning_content` (e.g. older DeepSeek SDKs).
`POST /v1thinking/chat/completions`	Reasoning and answer are merged into the normal `content` stream, wrapped in `<think>...</think>` tags.	Clients that ignore reasoning fields but should still display thoughts inline.

Per-request overrides (reasoning.delta_field, reasoning_delta_field, reasoning_content_compat) take precedence over the endpoint default. If a model does not emit reasoning, these fields are simply absent from the response.

Streaming output shape

When reasoning is delivered as a separate field, deltas are interleaved — reasoning chunks come first, followed by content chunks:

data: {"id":"chatcmpl-...","choices":[{"index":0,"delta":{"reasoning":"Let me think..."},"finish_reason":null}], ...}

data: {"id":"chatcmpl-...","choices":[{"index":0,"delta":{"content":"The answer is 4."},"finish_reason":null}], ...}

data: [DONE]

Against /v1legacy/chat/completions the same deltas use delta.reasoning_content instead of delta.reasoning. Against /v1thinking/chat/completions everything appears in delta.content:

data: {"choices":[{"delta":{"content":"<think>Let me think...</think>The answer is 4."}}]}

Non-streaming output shape

{
  "id": "chatcmpl-abc123",
  "object": "chat.completion",
  "choices": [{
    "index": 0,
    "message": {
      "role": "assistant",
      "content": "The answer is 4.",
      "reasoning": "Let me think..."
    },
    "finish_reason": "stop"
  }],
  "usage": { "...": "..." }
}

reasoning becomes reasoning_content on /v1legacy/. On /v1thinking/, the reasoning stays embedded inside content ("<think>...</think>The answer...") and no separate field is emitted.

Disabling Reasoning Output

Reasoning can be hidden in three equivalent ways — the model still pays the cost for reasoning compute, but the tokens are stripped from the response:

Request body: { "reasoning": { "exclude": true } }
Model suffix: "model": "deepseek-r1:reasoning-exclude"
Request body: { "reasoning_effort": "none" } (only honored on OpenAI-shaped models — safely ignored elsewhere for API parity).

When excluded, neither the reasoning field nor <think> tags appear in the response, regardless of which endpoint variant was hit.

Example

import requests

# Default: reasoning + content in separate fields
response = requests.post(
    'https://api.electronhub.ai/v1/chat/completions',
    headers={
        'Authorization': 'Bearer YOUR_API_KEY',
        'Content-Type': 'application/json'

        'messages': [{'role': 'user', 'content': "What's 2 + 2?"}],
        'reasoning_effort': 'medium'
    }
)
data = response.json()
print(data['choices'][0]['message']['reasoning'])  # thinking text
print(data['choices'][0]['message']['content'])    # answer
