At Chat-O, we have a simple obsession: getting you access to the best and latest AI models the moment they drop. We’re talking same-day access, no waiting around. We’re always watching for the next big release from every major AI lab, and if a model is good and meets our strict privacy standards, we get it on the platform. Fast.
Since this post was published, we’ve expanded our lineup significantly with new Kimi models including the 2.8 trillion parameter Kimi K3, and the complete Z-AI GLM family.
We curate every model on Chat-O against two bars:
When a new model clears both bars, we jump on it. Sometimes the same day. Sometimes within hours.
Moonshot AI’s Kimi K2 Thinking is a 1 trillion parameter MoE reasoning powerhouse that tops benchmarks like Humanity’s Last Exam and BrowseComp, beating GPT-5 and Claude Sonnet 4.5. It chains hundreds of tool calls autonomously and handles 256K context windows.
Since K2 Thinking, Moonshot has released Kimi K2.6, Kimi K2.7 Code, and the flagship Kimi K3 with 2.8 trillion parameters.
Deepseek’s experimental model uses “DeepSeek Sparse Attention” (DSA) to cut costs in half while maintaining quality. It’s especially efficient with long documents and conversations. Available in Balanced tier for cost-effective daily coding and brainstorming.
Anthropic’s Haiku 4.5 scores 73.3% on SWE-bench, matching Sonnet 4 on coding tasks while being twice as fast and a third of the cost. It includes vision support for analyzing images, screenshots, and diagrams.
| Model | Parameters | Context | Tier | Best For |
|---|---|---|---|---|
| Kimi K2 Thinking | 1T MoE | 256K | Power | Reasoning, agents |
| DeepSeek V3.2 Exp | ~600B | 128K | Balanced | Cost-efficient daily work |
| Claude Haiku 4.5 | - | 200K | Power | Fast coding, vision |
Every model on our platform carries one non-negotiable requirement: your data must never be used for training. We only partner with providers who guarantee this in their terms. Your conversations generate responses—nothing more. Your code, ideas, and documents stay yours. We turn down popular models if they don’t meet our privacy bar. For more details, see Keeping Chat-O Safe.
The result? You get the latest tech without the bloat of outdated models.

Q: Which model should I choose? A: Use “Auto” model selection to let us pick the best model for each task. Otherwise: DeepSeek V3.2 for cost-effective everyday work, Kimi K2 for tough reasoning, Claude Haiku 4.5 for fast coding and vision.
Q: What does “high privacy” mean? A: Your conversations are never used to train AI models. Processed for responses only, never stored for training.
Q: How does Kimi K2 compare to GPT-5? A: It outperforms GPT-5 and Claude Sonnet 4.5 on advanced reasoning and browsing benchmarks.
Q: Can Claude Haiku 4.5 really match Sonnet? A: Yes—on coding and agentic tasks, it performs on par with Sonnet 4 at twice the speed and a third of the cost.
Q: How quickly do you add new models? A: Often same-day, sometimes within hours if the model meets our performance and privacy standards.
Q: What happens to old models? A: We proactively retire them as better options become available. Past conversations remain accessible.
Chat-O is your gateway to the cutting edge of AI, curated for quality and protected by a non-negotiable commitment to privacy. The latest models, added daily. Always private. Always the best.
