Assessment. Moonshot's newest flagship, eight days old when read, for operators with a rack. Only llama.cpp has its model code in a release, with vLLM and SGLang support still on a release candidate and a branch. The licence is permissive below a revenue threshold, and Moonshot hasn't answered a discussion on the repository yet.

- Last release
From our research 11 facts checked against the vendor's pages
- Surface graded
- The open weights at huggingface.co/moonshotai/Kimi-K3.1-Pro, read from the model card, the files and their metadata, the licence, vLLM's recipe and SGLang's cookbook for the model, and the runtimes' own code at their latest releases on 10 November 2026. Nothing was downloaded or run. Moonshot's hosted API (platform.kimi.ai) isn't listed in the directory and isn't graded here
- Model
- A mixture of experts with 2.8T parameters and 104B active, 93 layers (69 Kimi Delta Attention and 24 gated DeepSeek Sparse Attention), 896 routed experts with 16 per token plus 2 shared, and a 401M-parameter MoonViT-V2 vision encoder. Text and images in. 2,780,110,363,392 parameters in the files per Hugging Face's metadata. The card says it was post-trained from Kimi K3
- Files
- 96 safetensors shards, MXFP4 expert weights (stored as U8) with BF16 and F32 for the rest, 1,561.3 GB stored. No pickle files. Hugging Face lists a SHA-256 for every shard. The repository also holds Python for the configuration, tokeniser, processor and prompt encoding, loaded with trust_remote_code
- Licence
- Kimi K3.1 Pro Licence, MIT-based, copyright Moonshot AI, for the code and the weights. A model-as-a-service business with more than $20 million in revenue over 12 months needs a separate agreement before commercial use, and products with over 100 million monthly users or $20 million a month in revenue must display "Kimi K3.1-Pro". Internal use and use through Moonshot's own products or certified inference partners are exempt. No acceptable use policy
- Runtimes
- llama.cpp b12242 has the kimi-k31 architecture and names this repository in its conversion code. vLLM 0.33.0 and SGLang 0.5.23 carry Kimi K3's model code only. vLLM's recipe needs 0.34.0, a release candidate on 10 November 2026, and SGLang's cookbook a branch or a development image. Transformers 5.22.2 has no kimi_k31 code and loads Moonshot's own from the repository. Ollama has a cloud entry only
- Prompt format
- No Jinja chat template in the repository and none in tokenizer_config.json. Prompts are rendered by encoding_k3.py, which Moonshot updated on 5 November 2026
- Tools and reasoning
- The card says tool calls and reasoning come back as tool_calls and reasoning_content and that the whole assistant message has to be passed back in later turns. vLLM's recipe and SGLang's cookbook parse both as kimi_k3. reasoning_effort is low, high or max per request, with max the default. The card links guides for structured output, partial mode, tool choice and dynamic tool loading on Moonshot's API
- Context
- 1,048,576 tokens, the context length on the card and max_position_embeddings in the text config
- Hardware
- The card states no memory needs. vLLM's recipe serves the MXFP4 checkpoint with tensor parallelism 8 on two GB300 trays, one B300 node or one MI355X node. The files are 1,561 GB and don't fit in 512 GB
- Training data
- One sentence on the card, large-scale joint reinforcement learning across hundreds of downstream domains on top of Kimi K3. No sources, sizes or knowledge cut-off
- Safety
- The card reports Moonshot's own cyber results, 74.7 on ExploitBench and 20.7 on ExploitGym. No independent evaluation of this model was found. The UK AI Security Institute's and CAISI's assessment of July 2026 was of Kimi K3
Facts verified 10 November 2026 from vendor docs, repositories and package registries. JSON · Markdown
Strengths
- Published weights for a model Moonshot calls its most capable, with a 1M-token context and images in
- Free commercial use under a modified MIT licence, ungated, with a hash on every file
- Moonshot's API and Together serve the same model for agents without the hardware
- reasoning_effort per request and several tool calls a turn
- vLLM and SGLang both publish serving recipes for it
Weaknesses
- 1,561 GB of files, so it needs a node of eight large accelerators at least
- Only llama.cpp has the model code in a release, and no GGUF is published
- No chat template, and prompts are built by code from the repository
- No limitations, safety guidance or security contact on the card, and no independent safety evaluation yet
- None of the newest discussions has a reply from Moonshot
Before you call it notes for agents
- Use Moonshot's API or Together unless you have a node of eight B300-class accelerators
- With vLLM use 0.34.0 or later and the recipe's flags,
--tool-call-parser kimi_k3 --reasoning-parser kimi_k3 - Pass the whole assistant message back in later turns, reasoning_content and tool_calls included, as the card requires
- Set
reasoning_effortto low, high or max per request. Max is the default and thinking can't be turned off - Kimi K3's model code doesn't load it, because the attention layers changed
- Validate JSON output yourself, since the card doesn't document structured output for the weights

Terms and privacy, as read
Terms of service none to read
TL;DR Nothing is hosted by the vendor, so there are no terms of service to read. The Kimi K3.1 Pro License (modified MIT) licence stands in and the check scores in full.
Privacy policy none to read
TL;DR Nothing is hosted by the vendor, so there is no privacy policy to read and the check isn't scored.
A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.
The .ai registry's RDAP server gave moonshot.ai a registration date of 15 December 2017, read 24 October 2026 for the Kimi K3 listing.
The licence names Moonshot AI. The Kimi Platform's terms name Moonshot AI PTE. LTD. as the party for its API, as the Kimi K3 listing records.
Nothing is hosted, so the Kimi K3.1 Pro Licence stands in for terms of service and no privacy policy is scored.
The changelog is the repository's commit history, two commits, the first on 2 November 2026 and an update to encoding_k3.py on 5 November.
No security.txt was found on moonshot.ai or kimi.com for the Kimi K3 listing on 24 October 2026. unchecked on 10 November.

Notable
- Published on Hugging Face on 2 November 2026. On 10 November it had 30,721 downloads and 1,834 likes, eight days after release source
- The card calls it Moonshot's most capable 3T-class model, post-trained from Kimi K3 with joint reinforcement learning across hundreds of domains, and the first model of the K3.1 series source
- Against Kimi K3, the 24 full-attention gated MLA layers are replaced with gated DeepSeek Sparse Attention layers for long contexts, so runtimes need new model code and K3's doesn't load it source
- Moonshot's table gives it 65.7 on Terminal-Bench 4.0 with the Claude Code harness and 79.6 on OSWorld V2.1 at max effort. These are Moonshot's numbers, not our measurement source
- vLLM's recipe asks for vLLM 0.34.0 or later, which had only a release candidate on 10 November 2026, and SGLang's cookbook installs from a kimi-k3.1-day-0 branch or a development image. llama.cpp b12242 has the kimi-k31 architecture and converts the repository source
- Ollama's library lists kimi-k3.1-pro as a cloud model only, and Hugging Face lists Together as a live inference provider source

Graded 48.6 D methodology v0.7
Fix list 16 items, the biggest gain first
Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Kimi K3.1 Pro. A fix counts at the next check, once it's public.
You're lucky. As part of the beta, your first month is free.
What we couldn't check
- Safety evaluation is 10 because the card's cyber benchmark results are read as the publisher's own safety results, the way the Kimi K3 listing reads its cyber evaluation. Read as capability results only, the line is 0 and Risk 40
- Trained tool calling is 20 on Kimi K3's tools channel and the card's multi-turn tool-call note. The K3.1 technical blog wasn't read
- File health is 10 with 13 discussions unanswered by Moonshot. If one of them reports a broken file, the line is 5
- Responsiveness read the 8 newest of 13 discussions. The other five weren't read
- Confidence is low by the checklist's rule, since no independent results were looked up on the day. The card cites Artificial Analysis and the APEX-Agents leaderboard for some rows, so Capability should be computable
- unchecked on 10 November: Moonshot's technical blog for K3.1 Pro, its API price, LM Studio's catalogue, the Kimi K3 card for a dated note, and security.txt on Moonshot's domains
- No sameModel set. Moonshot's API has no listing of its own
- Whether the Kimi K3 listing should set supersededBy to this one

Probe metrics
Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. The pollers record uptime for hosted endpoints as they run, and that doesn't change the score either.
Pricing & changes
Free Free Free to download and use, commercial use included, under the Kimi K3.1 Pro Licence. A company running a model-as-a-service business with more than $20 million in revenue over 12 months needs a separate agreement with Moonshot AI, at a price not published. Running it yourself costs the hardware, 1,561 GB of files (checked 2026-11-10).
What a task costs hosted estimated, per task

|---|---|---|---|
moonshotai/kimi-k3.1-proOpenRouter, $2 in and $10 out per 1M tokens | $2.98 | $1.06 | $0.23 |
Each figure is the same tokens priced at this model's rates, research report (134 fresh input, 207k cache writes, 10.5M cache reads and 46k output, the median of 156 runs), small website (48 fresh input, 106k cache writes, 2.2M cache reads and 40k output, the median of 4 runs) and bug fix (16 fresh input, 57k cache writes, 472k cache reads and 2k output, the median of 4 runs). We measured the tokens with Claude Opus 5.5 in Claude Code, so another model may use more or fewer tokens for the same job, and these compare prices, not how well or how efficiently each model works. Long-context surcharges, batch discounts and free allowances aren't counted. Prices are OpenRouter's for each model it serves from these weights. Run them yourself and the cost is your hardware and power. How we measured them.

Tell us where it is
We read it once now and again every week. If the link is missing two weeks in a row the listing says so, and a later check puts it back.
Agents send the same to POST /api/v1/verify as {"slug": "kimi-k3-1-pro", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.
