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.
We’re shipping new models all the time. Here are a few recent additions that we’re excited about, but think of this as just a snapshot of our promise: to keep Chat-O on the cutting edge.
We don’t just add every model that comes along, we actually curate them. Every model on Chat-O has to clear two high bars:
When a new model launches that meets both criteria, we jump on it. Sometimes that’s the same day. Sometimes it’s within hours. Our goal is to close the gap between “model announced” and “model in your hands.”
Our goal is also to provide the best multi-modal chat experience, with advanced RAG, image editing, audio and more. We are just getting started.
Moonshot AI’s Kimi K2 Thinking is a reasoning powerhouse, and it’s here to tackle your most complex problems.

Deepseek’s latest experimental model is all about efficiency, thanks to a brand-new architecture that delivers high quality at a reasonable cost.
What makes it special:
Released in September 2025, V3.2 Experimental is a glimpse into the future of efficient AI, offering incredible value in our Balanced tier.
Anthropic’s newest model, Haiku 4.5, packs the power of its bigger sibling (Sonnet) into a lightning-fast package.
What makes it special:
Released in October 2025, Haiku 4.5 is perfect for when you need top-tier AI that moves as fast as you do.
In the race for the latest AI, privacy can feel like an afterthought. Not here.
Every single model on our platform comes with a non-negotiable requirement: your data must never be used for training. We only partner with providers who guarantee this in their terms of service. No exceptions.
This means:
All three models highlighted here meet these strict criteria—just like every model we will ever add to Chat-O.
We don’t like clutter. We believe in a lean, powerful, and up-to-date model lineup.
The result? You get the latest tech, fast, without the bloat of outdated models. Every model in our lineup has earned its place.
Kimi K2 Thinking, Deepseek V3.2 Experimental, and Claude Haiku 4.5 are just the latest examples of our promise in action. And we’re just getting started.

Q: Which model should I choose?
A: We recommend using our “Auto” model selection. In this mode, we automatically choose the best model for your task, and you can get perspectives from multiple models within the same chat.
However, if you prefer to select a model yourself, here are our recommendations:
Q: Can I use my own API keys with these models?
A: These models are available through Chat-O’s integrated access. We do support Bring Your Own Key (BYOK) for some providers like OpenAI if you prefer.
Q: What does “high privacy” actually mean?
A: It means your conversations are never used to train AI models. Your data is only processed to generate a response and is never stored for training by us or our AI partners.
Q: How does Kimi K2 compare to GPT-5 and Claude Sonnet 4.5?
A: It outperforms both on several key benchmarks, particularly those measuring advanced reasoning and the ability to browse and act on information online.
Q: Can Claude Haiku 4.5 really match Sonnet?
A: Yes, on coding and agentic tasks, it performs on par with Sonnet 4 and achieves 90% of Sonnet 4.5’s performance—while being twice as fast and a third of the cost.
Q: How quickly do you add new models?
A: Often the same day they’re announced, sometimes within hours. If a model is good and private, we integrate it immediately.
Q: Do you add every new model?
A: Nope. We only add models that meet our high standards for both performance and privacy.
Q: What happens to old models?
A: We proactively retire them as better options become available. This keeps our platform clean and powerful. Your past conversations using those models remain accessible.
Q: How can I stay updated on new models?
A: Follow our blog! We announce new models here as they’re added. They’ll also appear automatically in your model selector inside Chat-O.
Chat-O is more than just a chat interface, it’s 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.
