Moonshot AI Kimi K2.6 API parameters

These are the API parameters modelparams.dev tracks for Moonshot AI Kimi K2.6 on Chat Completions with an API key — the settings you send in a request. Each row gives the type, default, valid range or values, and the conditions that gate it. It's the same data the JSON API serves.

After the parameter count instead — how many weights Kimi K2.6 has? That's a different number, and we don't track it. Here's the difference.

Length 2 params
Parameter Type Default Description Condition
Max completion tokens
max_completion_tokens 		integer (1…+∞) — Maximum number of tokens to generate in the chat completion. —
Stop sequence
stop 		string — Stops generation when this sequence is produced. Moonshot accepts up to 5 sequences of at most 32 bytes each. —
Reasoning 2 params
Parameter Type Default Description Condition
Thinking mode
thinking.type 		enum (enabled | disabled) "enabled" Controls whether Kimi reasons step by step before answering. Thinking is enabled by default; set disabled to respond directly. —
Keep prior reasoning
thinking.keep 		enum (all | ) null Set to all to carry reasoning content from earlier assistant turns into the request; leave null to send only the final answers. —
Tools 1 param
Parameter Type Default Description Condition
Tool choice
tool_choice 		enum (auto | none) "auto" Controls tool calling: auto lets the model decide and none blocks tool calls. Moonshot rejects required while thinking is enabled, which is the default on this model. —
Output 1 param
Parameter Type Default Description Condition
Response format
response_format.type 		enum (text | json_object) "text" Forces the response into plain text or a JSON object. —
Observability 2 params
Parameter Type Default Description Condition
Log probabilities
logprobs 		boolean false Controls whether the response includes log probabilities for the generated tokens. —
Top log probabilities
top_logprobs 		integer (0…20) — Number of most likely tokens to return a log probability for at each position.
Only when logprobs = true

How to use

modelparams.dev is an open, community-maintained catalog of model parameters. Each entry shows the knobs you can turn — type, default, range, and the conditions that gate it.

The same model accessed via an API key and via a subscription usually exposes a different set of parameters. We list both as separate entries so the data stays honest.

Catalog API

The full catalog is static JSON, CORS-enabled, served from the edge.

curl https://modelparams.dev/api/v1/models.json

Each entry is keyed by provider/model for API-key variants; subscription variants append -subscription.

If you only need the params for one model contract, use the providerless endpoint. Subscription contracts are model slugs with -subscription. 

curl https://modelparams.dev/api/v1/models/openai/gpt-5.5.json
curl https://modelparams.dev/api/v1/models/openai/gpt-5.5-subscription.json

Single model

curl https://modelparams.dev/api/v1/models/anthropic/claude-opus-4-7.json
curl https://modelparams.dev/api/v1/models/anthropic/claude-opus-4-7-subscription.json

JSON Schema

Every entry validates against a JSON Schema you can use in your editor or pipeline. 

curl https://modelparams.dev/api/v1/schema.json

Add this header to any YAML you author for autocomplete in VS Code: 

# yaml-language-server: $schema=https://modelparams.dev/api/v1/schema.json

Logos

Provider logos are available at /assets/logos/{provider}.svg where {provider} is the provider slug. They use currentColor so they inherit your text color. 

curl https://modelparams.dev/assets/logos/anthropic.svg

Logos are sourced from the models.dev repo (MIT) and used under nominative fair use.

Contribute

The data lives in YAML under models/{provider}/{model}-{auth}.yaml in the GitHub repo. Open a PR; CI validates against the schema and rebuilds.
