Opus 4.8, GPT‑5.5, Gemini 3.1 Pro — and more. Switch models mid‑conversation without losing context. Bring your own API keys or use ours. No credits, no limits.
The problem with AI today
Roughly $60 a month between ChatGPT Plus 23$, Claude Pro 15$ and Gemini AI Pro 22$ — and you still copy-paste between tabs to compare a single answer.
Five hundred credits. Are those messages? Tokens? It shifts with the model and the feature. You run out mid-project and never know why.
Your 'Pro' plan stops at 10 messages every three hours. A client brief halts mid-flight: ‘You’ve reached your limit.’ You’re paying monthly for the privilege.
One provider bills in tokens. Another in credits. A third in compute units. You can’t compare what you spend because no one uses the same currency.
You don't need three AI apps with three billing systems. You need one interface that gets out of your way.
How TalkFlux works
TalkFlux brings every frontier AI model into one place — and lets you decide how to pay for it. No lock-in. No confusion. No invented currencies.
Start with GPT-5.5 for speed. Switch to Claude for depth. Compare with Gemini for a second opinion. Same chat thread, full conversation history preserved.
Have your own OpenAI or Anthropic API keys? Plug them in — zero markup, no middleman. Don't have keys? Use ours with a transparent tiered markup (10–40% depending on request size). You can even mix: your keys for OpenAI, ours for Anthropic.
Every message shows its real cost in your currency. No tokens-to-credits conversion tables. A GPT-5.5 message costs $0.01? You see $0.01. We add a markup? You see that too.

Model usage activates only when you choose a paid plan. No timer, no card required, no 'upgrade to continue' walls.
TalkFlux uses a tiered markup based on the cost of each request. For small requests ($0.001–$0.01), the markup is 40%. For medium requests ($0.01–$0.05), it's 30%. For larger requests ($0.05–$0.20), it's 20%. And for the most expensive requests ($0.20+), it's just 10%. There's also a minimum charge of $0.001 per request. You always see the exact cost.
Yes, anytime. No penalties, no waiting periods. If you start with Flex and later get API keys, switch to Own Keys and stop paying markup instantly. If you switch mid-month, you only pay the prorated amount. You won't lose any conversations, projects, or settings.
Model usage pauses. That's it. No surprise charges, no overdraft, no 'we'll bill you the difference.' You get a notification and can top up your balance at any time. Your conversations and projects stay exactly where you left them.
If you only use one model, you probably should — TalkFlux adds the most value when you want access to multiple providers. Where we save you money and time: you don't need three $20/month subscriptions to try different models. You can compare outputs in the same chat. And with Own Keys, you pay the exact same API rate as going direct — with a better interface and all your models in one place.
Your API keys are encrypted at rest using AES-256-GCM — the same standard used by banks and cloud providers. We never log key values, and they're only decrypted in memory when sending a request to the provider on your behalf. Your conversations are stored securely and are never used to train any model. You can delete your data at any time.
We aim to add new frontier models within days of their public API release. GPT-5.5 was available on TalkFlux within 48 hours of OpenAI's API launch. We monitor all three providers and ship model updates as fast as we can test them.
