Model selection guide

Choose by task, not by hype

Start with Auto, or choose a fixed model when its strengths and tradeoffs match the work.

Auto

Best for: Most everyday tasks and first-time users
Why choose it: Routes each request to a suitable available model without making you compare every specification first.
Watch for: Routing can change by task and availability; select a fixed model when reproducibility matters.

DeepSeek V4 Flash 0731

Best for: Fast coding, reasoning, and long analysis
Why choose it: Balances a large context window with lower-cost responses for iterative work.
Watch for: Fast output still requires tests and source verification for consequential work.

DeepSeek V4 Pro 0813

Best for: Hard coding, math, and multi-step tool use
Why choose it: Prioritizes deeper reasoning and agentic execution over the fastest response.
Watch for: Longer reasoning can increase latency and usage.

Gemini 3.8 Flash

Best for: Images, documents, and quick multimodal synthesis
Why choose it: Combines fast reasoning with vision and document-oriented work.
Watch for: Exact extraction should be checked against the original file or image.

GLM 5.2

Best for: Coding, math, multilingual and multimodal analysis
Why choose it: A strong general reasoning option when the task crosses languages or modalities.
Watch for: Model confidence is not evidence; request sources for current or high-stakes claims.

Qwen3.7 Plus

Best for: Structured multilingual reasoning
Why choose it: Useful for constrained outputs, math, code, and cross-language work.
Watch for: Review locale-specific tone and terminology before publication.

Kimi K2.6

Best for: Long documents and large-context synthesis
Why choose it: Designed for document-heavy chat, coding, and evidence organization.
Watch for: Large context does not guarantee every detail is weighted correctly; ask for locations and quotations to audit coverage.

Known limits

What AI chat cannot guarantee

Answers can be wrong

Language models can fabricate facts, citations, calculations, and code behavior. Verify primary sources, run code, and use qualified review for medical, legal, financial, or safety decisions.

Capabilities vary by model

Vision, context length, tools, speed, and plan access come from the selected live model. A feature available on one model is not promised for every model.

Current information needs retrieval

A model’s built-in knowledge is not a live source. Enable source context or ask for web research when dates, prices, releases, people, or policies may have changed.

Sensitive input needs judgment

Do not submit secrets or data you are not authorized to process. Review GizAI privacy terms and your organization’s data policy before using confidential material.

Anonymous access is limited

No-sign-up use applies only to models with an Included allowance. Other models may require sign-in, a plan, or usage credit, as shown in the live picker.

Editorial transparency

How this page was reviewed

Written by GizAI Product Team · Reviewed by GizAI Model Operations · Updated 2026-07-16

GizAI publishes this AI chat page about its own product. Model names, inputs, controls, access, and plan requirements come from the live GizAI catalog; examples and editorial guidance explain practical use without promising flawless output.

Match the AI chat default, offered models, and example inputs to active GizAI model contracts.
Run the public form through model selection, example application, and the canonical Assistant handoff.
Check that examples state a concrete task, output contract, and verification requirement instead of promising flawless answers.
Verify one canonical URL, visible FAQs, structured data, internal links, desktop layout, and mobile layout.

Clear answers

AI chat questions, answered clearly

Can I use this AI chat without signing up?

Yes, when you select a model marked Included for anonymous use. Anonymous allowances are limited. Models that require an account, plan, or usage credit show that requirement in the picker before you send.

Which AI models can I chat with?

The page currently offers Auto routing plus active GizAI chat options including DeepSeek V4, GPT-5.6 Luna, Gemini 3.5 Flash, GLM 5.2, Qwen3.7, Grok 4.6, Kimi K2.6, and MiniMax M3. The live picker is authoritative for availability and access.

What does the Auto model do?

Auto routes the request to a suitable available chat model. Use it when you care about the result more than a specific provider. Choose a fixed model when you need repeatable model behavior or a particular capability.

Can AI chat analyze images and files?

Supported vision models can receive an image from this form. After the handoff, the full GizAI workspace can also use files and other context. Accepted inputs and limits depend on the selected model and are shown in its settings.

Can it search the live web and cite sources?

Yes, when source context and tools are enabled. Ask for primary sources and citations explicitly, then open and verify the linked material. A citation-shaped answer is not proof that the source supports the claim.

Which model should I choose for coding?

Start with Auto for routine work. DeepSeek Flash is suited to fast iterative coding, while DeepSeek Pro is intended for harder reasoning and multi-step work. Regardless of model, inspect the diff and run the relevant tests.

Does GizAI train models on my chat?

Data handling depends on GizAI and the providers involved in the selected service. Review the current privacy policy before sending sensitive information; do not rely on a generic AI-chat privacy assumption.

How current are AI chat answers?

Model memory has a cutoff and may be incomplete. For time-sensitive questions, use live source context, require dated citations, and verify the original source.

Are AI chat answers safe to publish or act on?

Not without review. Check facts, rights, privacy, calculations, and code behavior. High-stakes medical, legal, financial, or safety decisions need qualified human judgment and authoritative sources.
