FAQ
Which AI Models Does Prompt Anything Pro Support?
Quick Answer
Prompt Anything Pro supports 30+ models across seven providers via BYOK: OpenAI, Anthropic, Google, xAI, and Groq on the cloud side, plus local models through Ollama or LM Studio and Chrome's built-in AI (Gemini Nano) on the device side. The current flagships are OpenAI's GPT-5.4, Anthropic's Claude Opus 4.6, Google's Gemini 3.1 Pro, and xAI's Grok 4.3, alongside faster low-cost tiers (GPT-5.4 Mini, Claude Haiku 4.5, Gemini 3.1 Flash), OpenAI's o3 and o4-mini reasoning models, and a set of earlier GPT-4.1, Claude, and Gemini releases kept available for compatibility. You configure each cloud provider's API key once — local and on-device models need no key at all — and switch models per-prompt with a one-click dropdown. New provider models become available within days of their API launch.
- OpenAI: GPT-5.4 (flagship), GPT-5.4 Mini (cheap/fast), o3 and o4-mini (reasoning), plus the GPT-4.1 family.
- Anthropic: Claude Opus 4.6 (flagship, strongest for writing + analysis), Claude Sonnet 4.6 (balanced daily driver), Claude Haiku 4.5 (fast/cheap).
- Google: Gemini 3.1 Pro (flagship, best for long documents), Gemini 3.1 Flash (fastest, cheapest tier), plus LearnLM 2.0 for explanation-heavy tasks.
- xAI: Grok 4.3 (flagship) and the rest of the Grok line. Groq: fast open-weight models when throughput matters more than frontier quality.
- Local and on-device: Ollama, LM Studio, and Chrome's built-in AI (Gemini Nano) — no API key, no per-token bill, nothing leaves your machine.
- 30+ models in total across 7 providers. Switch per-prompt with a single dropdown click. BYOK means new models from any provider work the same day they launch in the API.

OpenAI Models
OpenAI offers the broadest range of models, from powerful reasoning engines to fast, cost-effective options. Prompt Anything Pro supports the full range of OpenAI's chat completion models.
- GPT-5.4 — OpenAI's current flagship. Best all-around choice for complex reasoning, creative writing, code generation, and analysis.
- GPT-5.4 Mini — A smaller, faster, cheaper sibling of GPT-5.4. Great for high-volume work like summarization, rewriting, and quick Q&A.
- o3 and o4-mini — OpenAI's reasoning-optimized models. Worth reaching for on multi-step problems, maths, and tricky debugging where you want the model to think before answering.
- GPT-4.1, GPT-4.1 Mini, and GPT-4.1 Nano — The previous generation, still selectable if you have prompts or workflows tuned to them.
- Per-token rates differ for every model and change over time — check OpenAI's pricing page for the current numbers before you settle on a default.
Anthropic Models
Anthropic's Claude models are known for strong reasoning, nuanced writing, and reliable instruction-following. Many users prefer Claude for writing-heavy tasks and complex analysis.
- Claude Opus 4.6 — Anthropic's most capable model. Excels at nuanced writing, long-form analysis, coding, and tasks that need careful step-by-step reasoning.
- Claude Sonnet 4.6 — The balanced mid-tier. Close to Opus on most everyday work at a lower per-token rate, and the sensible default for daily writing and editing.
- Claude Haiku 4.5 — Optimized for speed and cost. Ideal for quick tasks where you want Claude's writing style without paying flagship rates.
- Claude Sonnet 3.5 — An earlier release, still selectable for workflows already tuned to it.
- Rates vary per model — see Anthropic's pricing page for the current per-token cost of each.
Google Models
Google's Gemini family offers competitive performance with aggressive pricing. They are especially strong at factual queries and tasks that benefit from Google's training data.
- Gemini 3.1 Pro — Google's current flagship. Strong on long-document work, codebases, and large datasets, and the Gemini model to reach for first.
- Gemini 3.1 Flash — The fast, lightweight tier. Built for speed and high-volume simple tasks at a fraction of Pro's cost.
- Gemini 2.5 Pro and Gemini 2.5 Flash — The previous Pro/Flash pair, still available for workflows already tuned to them.
- Gemini 2.0 Flash, Gemini 2.0 Flash-Lite, Gemini 1.5 Pro, and Gemini 1.5 Flash — Earlier releases retained for compatibility.
- LearnLM 2.0 — Google's model tuned for teaching and explanation. Useful when you want a concept broken down rather than a direct answer.
- Context limits and per-token rates differ across the family — Google's pricing page has the current figures.
xAI Models
xAI's Grok family is the newest addition to the cloud line-up. It is worth reaching for when you want a different reasoning style from the OpenAI/Anthropic/Google trio, or a second opinion on a hard problem.
- Grok 4.3 — xAI's current flagship, and the Grok model to start with.
- The rest of the Grok line is selectable from the same dropdown once your xAI key is configured.
- Per-token rates are published on xAI's API page — check there before setting Grok as a default.
Groq
Groq is an inference provider rather than a model lab: it serves open-weight models on custom hardware at very high token throughput. Use it when latency matters more than frontier reasoning quality — bulk summarizing, translation passes, or anything you run dozens of times an hour.
- Fast open-weight models served at a fraction of flagship latency.
- Same BYOK setup as every other cloud provider: paste a key once, then pick the model per prompt.
- Current model list and rates live on Groq's pricing page.
Local and On-Device Models (No Key Required)
Two of the seven providers never touch the network. If you run a model locally through Ollama or LM Studio, or use Chrome's built-in AI, the text you select never leaves your machine — there is no API key, no per-token bill, and no external privacy policy to trust. The trade-off is capability: a local model will not match GPT-5.4 or Claude Opus 4.6 on hard reasoning, so the practical pattern is on-device for anything sensitive and a cloud key for anything that needs frontier quality.
- Ollama — Point Prompt Anything Pro at your local Ollama server and use whichever models you have pulled.
- LM Studio — Same idea with LM Studio's local server, if that is your preferred runner.
- Chrome's built-in AI (Gemini Nano) — Runs inside the browser itself. Nothing to install, no key, no network round-trip.
- Zero marginal cost: local and on-device prompts do not appear on any provider invoice.
How to Switch Between Models
Prompt Anything Pro makes model switching effortless. In the extension settings, you configure API keys for each provider you want to use. When you trigger a prompt (by highlighting text and using the context menu or keyboard shortcut), you can select which model to use from a dropdown. You can also set a default model that is used automatically unless you override it. Switching models takes one click — there is no need to change settings pages or reconfigure anything.
Which Model Should You Use?
Different models have different strengths. Here is a practical guide for choosing the right model for common tasks.
- Complex analysis or reasoning — GPT-5.4 or Claude Opus 4.6. Both are top-tier; try both and see which style you prefer. For multi-step problems, o3 is worth a look too.
- Creative writing and editing — Claude Opus 4.6 and Claude Sonnet 4.6 tend to produce more natural, nuanced prose. GPT-5.4 is also excellent but can read as more formulaic.
- Code generation and debugging — GPT-5.4 and Claude Opus 4.6 are both strong. Run the same prompt through each on a task you already know the answer to, then keep whichever you trust more.
- Summarization and quick tasks — GPT-5.4 Mini, Claude Haiku 4.5, or Gemini 3.1 Flash. Fast and cheap, more than capable for straightforward work.
- Long document processing — Gemini 3.1 Pro. Context limits differ per model, so check the provider's model card before pasting something very large.
- Budget-conscious daily use — GPT-5.4 Mini or Gemini 3.1 Flash for most tasks, escalating to GPT-5.4 or Claude Opus 4.6 only for complex work.
Adding New Models as They Launch
The AI landscape moves fast, with new models launching regularly. Because Prompt Anything Pro uses the BYOK (Bring Your Own Key) approach, new models are typically available in the extension within days of their API launch. When any supported provider — OpenAI, Anthropic, Google, xAI, or Groq — releases a new model, we update the extension's model list to include it. Since you use your own API key, there is no vendor-side provisioning delay — as soon as the model is available in the provider's API, you can use it through Prompt Anything Pro.
