But the actual numbers you need for a build decision — context window, benchmarks, and real token pricing — are scattered across launch posts and docs. I got tired of reconciling five tabs, so I put them side by side.</p> <h2> One table </h2> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th></th> <th>Kimi K3</th> <th>Kimi K2.6</th> <th>Fable 5</th> <th>GPT</th> </tr> </thead> <tbody> <tr> <td>Context</td> <td>1M tokens</td> <td>256K (262,144)</td> <td>see vendor</td> <td>see vendor</td> </tr> <tr> <td>API input</td> <td>$3.00 / 1M</td> <td>$0.95 / 1M</td> <td>premium</td> <td>premium</td> </tr> <tr> <td>API output</td> <td>$15.00 / 1M</td> <td>$4.00 / 1M</td> <td>premium</td> <td>premium</td> </tr> <tr> <td>Open weights</td> <td>✅</td> <td>✅</td> <td>❌</td> <td>❌</td> </tr> </tbody> </table></div> <p>One pricing detail worth flagging: K3's <strong>cache-hit input drops to $0.30 / 1M</strong>. If you run long system prompts or multi-turn agents, that's where the "cheap" reputation actually comes from — not the base rate.</p> <h2> A few things that stood out </h2> <ul> <li> <strong>Front-end/UI is its strongest suit.</strong> It hit #1 on the Frontend Code Arena (1679) on launch day, above Fable 5. That's the most consistent praise I've seen in the threads.</li> <li> <strong>It's a large sparse MoE.</strong> Active params are a fraction of total, which is a big part of why the per-token price is what it is — it's not "a smaller model," it's cheaper inference.</li> <li> <strong>Self-hosting isn't realistic for most people.</strong> The total parameter count is datacenter territory; the practical routes are quantized community builds or hosted inference (OpenRouter is a couple of bucks to just try it).</li> </ul> <h2> Caveats </h2> <p>Where I couldn't confirm an official number I left it blank instead of guessing. Pricing is per Moonshot's stated rates — <strong>verify against the official pages before you build on it.</strong> Benchmarks are one signal, not the whole story; for "does the output actually feel good," throw a couple of dollars at your own hardest task.</p> <p>Full table and more fields here (disclosure: I built the page): <a href="https://kimi3.online" rel="noopener noreferrer">https://kimi3.online</a></p> <p>If you've run K3 in anger, I'd love corrections — especially on backend/reasoning vs Sol 5.6.</p> ai api llm news
