Astra, Sol, Terra, or Luna: Which GPT-6 Model You Actually Need
Find out which OpenAI model you can use for different types of tasks to make sure you get the depth or speed you need to carry out your work.
Sol balances capability and speed for day-to-day tasks
Use Sol for tasks like basic coding and business workflows as the model handles ambiguity with more depth than Luna, but works faster than Astra.
Astra brings maximum depth to consequential work
Work with Astra for advanced codebases and important decisions where missing a dependency could change the outcome.
Luna delivers the fastest outputs for repetitive work
Select the Luna model for tasks such as structured extraction and routine coding when volume matters more than depth.
Terra combines visual reasoning with efficient computer use
Select Terra for tasks like interpreting diagrams and filling out forms when you need capable automation at a lower cost than Sol or Astra.
What Makes GPT-6.1 Models Stand Out
GPT-6 models have key features designed to help you complete different types of tasks from bulk processing to the most difficult technical work.
| Capability | What you can use it for |
|---|---|
| Advanced coding | Trace a production failure across services, implement the fix, write the tests and provide rollback steps, with the tier chosen to match the risk and scope. |
| Whole projects at once | Work across repositories, document collections, logs and research material together so the result accounts for the dependencies between them. |
| Visual reasoning and computer use | Try Terra to analyze diagrams, extract invoice details, and complete forms and combine visual understanding with practical processes. |
| Work that runs through the steps | In a tool-enabled environment, plan a multistep job, act on the available tools, check progress and report what still needs a person’s decision. |
| Different versions for different workloads | Use Luna for routine volume, Terra for visual tasks and cost-efficient automation, Sol for the daily middle ground, and Astra for work where added depth earns the extra time. |

ChatGPT-6 Example Workflow: See How the OpenAI Model Family Delivers on Coding
See how GPT-6 can structure a large ticket batch while flagging cases that need human judgment.
Convert these 200 support tickets into valid JSON. For each ticket, include its ID, category, urgency, summary, recommended action and whether it needs human review. Use only the ticket content, flag missing information and check that every source ticket is represented.
- output/tickets.json — 200 structured records - scripts/validate-tickets.ts — schema and completeness checks - tests/validate-tickets.test.ts — regression coverage
Output:
1const TicketRecord = z.object({2 ticket_id: z.string(),3 category: z.enum(["billing", "permissions", "technical", "other"]),4 urgency: z.enum(["low", "medium", "high", "unknown"]),5 summary: z.string().min(1),6 recommended_action: z.string().min(1),7 needs_human_review: z.boolean()8});910const records = TicketRecord.array().parse(11 JSON.parse(await readFile("output/tickets.json", "utf8"))12);1314const sourceIds = new Set(sourceTickets.map(ticket => ticket.id));15const outputIds = new Set(records.map(record => record.ticket_id));1617assert.equal(records.length, sourceTickets.length);18assert.deepEqual(outputIds, sourceIds);Validation output: $ npm run validate: tickets Loaded source tickets: 200 Validated JSON records: 200 Unique ticket IDs: 200 Flagged for human review: 2 Missing or duplicate IDs: 0 Validation passed.

Lorka AI combines Astra, Sol, Terra, and Luna together with Claude Opus, Gemini, Grok and other frontier AI models so you can choose for the task instead of having to use separate chats.
Multiple models, one chat
Move from Sol to Astra for a hard dependency or to Luna for a repetitive batch without rebuilding the conversation.
Create supporting images
Turn a product concept or written draft into visuals with the AI image generator that features the latest versions of GPT Image, Nano Banana, and more.
Compare with the same materials
Run the same prompt and files through GPT-6, Claude Sonnet, DeepSeek, GLM, and more to test outputs and find out what works best.
Match capability to workload
Reserve the deepest tier for decisions and implementation work that justify it; use faster tiers for classification, extraction and routine iterations.
Save with a multi-model platform
Pay $29.99 a month for every included model in the same AI chat instead of paying for separate subscriptions.
