Selecting the Right AI Model

magicdoor.ai lets you use multiple AI providers in one interface. The practical benefit is that you can choose the model that fits the task instead of forcing one provider to do everything.

magicdoor.ai also offers renewable-powered inference for GLM-5.3, GLM-5.3 Flash, Kimi K3, and DeepSeek V4.1 Flash. DeepSeek V4.1 Flash's default route remains pinned to Fireworks with zero data retention.

Strong starting point

Claude Sonnet 5.5 is a strong general-purpose starting point for writing, analysis, code, and most everyday work.

Current chat lineup

magicdoor.ai currently offers 14 chat models across six upstream providers:

• GPT-6.1 Sol: Default OpenAI option at $2/$10 per 1M input/output tokens
• GPT-6 Astra: Optional subscriber-only premium OpenAI option at $10/$50
• Claude Opus 5.5: Premium Claude option at $4/$20
• Mistral Large 4 (Le Chonk): Mistral via pinned Vercel AI Gateway, text and image input; current Gateway sale rates $0.68/$2.09 per 1M input/output tokens, subject to change. Read route limits and privacy details.
• Kimi K3: Together AI option at $3/$15
• GLM-5.3: Together AI coding and reasoning option at $1.40/$4.40
• GLM-5.3 Flash: Fast, lower-cost Together AI option at $0.15/$0.50
• Grok 4.7: xAI option at $2/$6 below 200K tokens
• DeepSeek V4.1 Flash: Fast multimodal Fireworks option at $0.22/$0.66 with ZDR routing
• GPT-6 Luna: Lower-cost OpenAI option at $0.10/$0.50
• Claude Sonnet 5.5: General Claude starting point at $2/$10
• Claude Haiku 5.5: Lower-cost Anthropic option at $0.10/$0.50 for up to 100K input tokens, or $0.50/$2.50 above 100K
• Qwen3.8 Max: Together AI option at $2.50/$6.25
• Claude Fable 5.1: Premium subscriber-only Claude option at $10/$50

Prices are per 1 million input/output tokens. GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna input, cached-input, and cache-write prices double above 272K input tokens for an individual request, while output becomes 1.5 times the base rate. Grok 4.7 input and output pricing doubles at 200K tokens or more. Claude Haiku 5.5 uses its higher input/output and cache tiers above 100K input tokens for a request. GPT-6 Astra and Claude Opus 5.5 are subscriber-only.

Simple selection guide

• Use Claude Sonnet 5.5 when you want a strong default.
• Use GPT-6.1 Sol as the default OpenAI option, or subscriber-only GPT-6 Astra for the hardest end-to-end work.
• Use GPT-6 Luna, Claude Haiku 5.5, or DeepSeek V4.1 Flash when cost matters.
• Try Mistral Large 4 (Le Chonk) for a text-and-image second opinion; the Gateway context ceiling is 524,288 tokens and PDFs are not supported on this route.
• Use Exa-backed web search when the task depends on current web information.
• Use Claude Opus 5.5 when the task justifies a premium model.
• Use GLM-5.3, GLM-5.3 Flash, Qwen3.8 Max, or Kimi K3 when you want to compare a Together AI model; use DeepSeek V4.1 Flash for the pinned Fireworks ZDR route.

Why switching models matters

One model is not best at everything. A common workflow is:

• research with Exa-backed web search
• synthesize with Claude Sonnet 5.5 or GPT-6.1 Sol
• drop to GPT-6 Luna, Claude Haiku 5.5, or DeepSeek V4.1 Flash for cheaper follow-up work

magicdoor.ai lets you switch models during a conversation so you can change tools without losing context.

Managing cost

The biggest cost drivers are:

• how long the conversation has become
• which model you are using
• whether the workflow includes image generation or web-connected research

Long chats cost more because the model has to process more prior context. Premium models also cost more than Luna, Claude Haiku 5.5, DeepSeek V4.1 Flash, or other lower-cost options. If you want concrete examples, see cost per model.

Tips

• start a new chat when you switch topics
• use lower-cost models for drafts and summaries
• save premium models for high-value work
• turn on Exa-backed web search only when you actually need live web results

Compare models without rebuilding the conversation

magicdoor.ai lets you switch models mid-conversation and shows live cost monitoring while you work. A practical flow is to start with Claude Sonnet 5.5, switch to a different provider for an independent critique, and move to a lower-cost model for routine revisions.

Basic is $6 per month with $2 usage balance in the first month and $1 on renewal; Plus is $12 with $7 monthly usage balance. Additional usage is metered; compare your own workload rather than assuming a typical total. This suits moderate, varied use; heavy users with predictable volume may be better served by a flat-rate provider plan.

What renewable inference changes

For GLM-5.3, GLM-5.3 Flash, Kimi K3, and DeepSeek V4.1 Flash, you can select Renewable beside the model or enable Prefer renewable inference in chat preferences. GreenPT attributes the supported route's EU infrastructure as 100% renewable-powered and provides per-response inference time, energy use, and CO2e estimates with methodology caveats. The estimate is stored only for the current browser session. DeepSeek V4.1 Flash's default route remains pinned to Fireworks with zero data retention. Large 4 has no GreenPT route.

This is an inference claim, not a training claim. It does not mean every magicdoor.ai model runs through GreenPT, and GreenPT's infrastructure and privacy claims do not extend to magicdoor.ai's wider account or chat-storage architecture.

FAQ

Which model should I start with on magicdoor.ai?

Start with Claude Sonnet 5.5 for most writing, analysis, and general work. Switch to a lower-cost model such as GPT-6 Luna, Claude Haiku 5.5, or DeepSeek V4.1 Flash when the task is routine.

Which magicdoor.ai model should I use for current web research?

Use Exa-backed web search with a supported chat model when the task needs current web information or citations, then continue with the selected model for synthesis.

Can I switch models during one conversation on magicdoor.ai?

Yes. magicdoor.ai supports switching models mid-conversation, so you can use one model for research, another for writing, and another for lower-cost follow-up work.

Which OpenAI models are available on magicdoor.ai?

The current magicdoor.ai lineup includes GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna for chat. Sol remains the default; Astra is an optional subscriber-only premium model. All three support code interpreter workflows on magicdoor.ai.

How should I choose image models on magicdoor.ai?

Pick image models by task: Seedream 5 Pro for multi-reference generation, Flux 2 Pro for targeted edits, GPT Image 2.5 Flare for the OpenAI image workflow, and Recraft Upscaler when you only need upscaling.
