Kimi K2.6 on QuickSilver Pro
Kimi K2.6 is Moonshot's general-purpose agentic model for long-horizon planning, coding, and multimodal work. On QuickSilver Pro it is $0.45 input / $1.95 output per million tokens, at parity with the OpenRouter endpoint selected by this route, with no markup or discount. There's no clean OpenAI analog — if your evals are picking Claude Opus or GPT-5 for agentic depth, K2.6 is the open-source comparable to A/B test.
At a glance
Long-horizon agentic / planning workloads where Opus-class depth matters.
Pricing comparison ($/1M tokens)
| Provider | Input | Output | vs QSP |

| OpenRouter (moonshotai/kimi-k2.6) | $0.45 | $1.95 | same |
When to use
Multi-step planning agents that need to coordinate tools across long horizons, research / analyst agents that synthesize across many documents, complex code-review or refactor agents that plan before acting, and any workload where DeepSeek V4 Pro's pure-math reasoning isn't the same as K2.6's agentic / long-context planning. The 256K context fits a substantial codebase or research corpus.
When to use something else
For routine chat, coding, or short-context tasks, K2.6 is overpriced — use V4 Flash. For pure mathematical reasoning, V4 Pro wins. For a native tool ecosystem, Claude or OpenAI — though we serve Claude too, and 38 of our 83 models take image input.

FAQ
On the evals Moonshot published with the April 2026 release, K2.6 lands within striking distance of Claude Opus 4 on agentic tool-use benchmarks (Tau-bench, SWE-bench Verified) and ahead on long-context retrieval. Match on your own evals before committing — Opus has been finetuned in production longer and may still win on subjective quality for some tasks. If your selection process picks Opus, K2.6 is the open-source alternative worth A/B testing.
$0.45 input / $1.95 output and $0.045 cache read per million tokens, matching the route-selected OpenRouter endpoint (chutes int4) with no markup or discount. The route uses its pinned provider order or the cheapest eligible endpoint under sort: price and its quantization filters; the /models headline can differ. More expensive fallback hosts do not change your price. Use base_url=https://api.quicksilverpro.io/v1 and model="kimi-k2.6".
Yes — K2.6 is an OpenAI-compatible chat completions endpoint on QuickSilver Pro. Set base_url=https://api.quicksilverpro.io/v1, paste your QSP key, use model="kimi-k2.6". Streaming, tool calling, json_schema strict mode, and usage.cost accounting all work. K2.6 thinks by default; pass `reasoning: { enabled: false }` for non-thinking output (though for the workloads K2.6 is built for, you usually want the thinking trace).
