Qwen3.8-2.4T-A95B: 2.4T total parameters, 95B active per token, 262K native context extensible to 1M via YaRN, qwen3.8-max license. Kimi K3: published by Moonshot AI with a 1M-token context window, Moonshot's published Kimi K3 license. Both route through OneInfer via OpenAI-compatible endpoints. Both ship open weights.

No published same-harness benchmark table

Neither Moonshot nor Alibaba publishes a shared benchmark table running Kimi K3 and A95B on the same harness. A95B scores 86.6 on Terminal Bench 2.1, 92.6 on GPQA Diamond, 67.7 on SWE-bench Pro, 73.5 on FrontierSWE — all on Qwen's published harnesses. Kimi K3's published scores are on Moonshot's own eval harness. State the absence before quoting any side-by-side number.

When to pick Kimi K3

You specifically want Moonshot's published Kimi K3 license terms over the qwen3.8-max license.
You have a workload that has been pre-tuned on Kimi K3 and a switch is more costly than the 3× output premium.
You are running inference on hardware or a serving stack that has been benchmarked against Kimi K3 already.

When to pick A95B

Per-token cost dominates the buying decision. Output-heavy workloads in particular.
You are running workloads where 262K native / 1M extended context is required and YaRN extension is acceptable.
You want the Qwen vendor benchmark record reproduced on Anthropic / OpenAI / Google frontier harnesses.

Caveats

Kimi K3's published license is Moonshot's Kimi K3 license, not Apache or MIT. Read the license tag on the official Hugging Face repository before self-hosting at scale.
Cache-read rates for Kimi K3 are not consistently published; the headline rates above are uncached.
A95B requires thinking mode on every call. Kimi K3 has not been documented as requiring thinking mode.
