What's new in GPT-6 Astra Pro 6.0

  • 1.05M token context, output up to 128K
  • Same weights as GPT-6 Astra, served with reasoning.mode = pro
  • More internal reasoning per step for higher quality on hard tasks
  • Text, image and file input, text output
  • Structured outputs, tool calling and seed for reproducibility
Strengths

What it's the best tool for

  • Same weights as GPT-6 Astra, served with reasoning.mode = pro
  • 1.05M token context, up to 128K tokens in a single reply
  • Text, images and files in one request
  • Tool calling in three modes: auto, required and a named function
  • Structured outputs against a JSON schema, plus seed and reasoning_effort
Limitations

When to reach for something else

  • Slower than base Astra: pro mode thinks longer at every step
  • Burns noticeably more reasoning tokens, so the same task costs more
  • On short, unambiguous prompts it gains little over base Astra
  • Text output only: the model does not generate images or video
  • No built-in web search in chat, fresh data has to come in the prompt
Sample output

How GPT-6 Astra Pro responds

Prompt
Here is a quarter of billing exports plus the contractor agreement. Find the charges that do not match the contract terms, explain which clause each one breaks, and tell me what extra data is needed to settle the disputed lines.
GPT-6 Astra Pro
Reconciled 412 charges against the contract; four look wrong. 1) Rows 87 and 214: hourly rate above Annex 2, clause 4.1 — 36 hours overbilled. 2) Row 190: weekend work billed with a multiplier that the contract never defines. 3) Row 301: duplicates row 298 — same ticket, same time interval. 4) Row 355: milestone billed before the acceptance date, clause 6.3 allows payment only after signing. To settle this you need the March acceptance acts and the contractor timesheets for tickets 4471 and 4488.
Where teams use it

Four scenarios where it pays for itself

01
Hard coding tasks
Reading a large repo and finding non-obvious bugs on 1M context
02
Agent pipelines
Multi-step scenarios with reliable tool calling
03
Document work
Long contracts, reports and screenshots in a single request
04
Analysis and math
Long derivations where every reasoning step matters

More about GPT-6 Astra Pro

GPT-6 Astra Pro Online — the Deeper Reasoning Mode of GPT-6 Astra

GPT-6 Astra Pro is the same OpenAI model as GPT-6 Astra, served with reasoning.mode = pro. There are no separate Pro weights: the whole difference is how long the model thinks before it answers. On NetRoom both versions live in the same chat, with no VPN and no foreign card required.

What pro mode buys you

Pro spends more internal reasoning on every step. On tasks where the answer depends on a dozen linked conditions — reading unfamiliar code, long calculation chains, auditing a document for contradictions — you see it in the number of details it does not drop. On short, unambiguous prompts the difference is marginal: base Astra returns the same answer sooner.

Specifications

  • 1.05M token context, up to 128,000 tokens in a single reply
  • Input: text, images and files. Output is text only
  • Tool calling: auto, required, and calling a named function
  • Structured outputs against a JSON schema plus response_format
  • seed and reasoning_effort parameters for reproducibility and depth control

When Pro is worth it and when base Astra is enough

Pro pays off when a mistake costs more than the wait: refactoring a large module, reconstructing an incident from logs, checking a contract against its annexes, running a multi-step agent that cannot go wrong halfway. For chat, drafts, summaries, simple scripts and routine support replies, take base Astra — it replies faster and burns fewer reasoning tokens. Pro does not add a surcharge for the mode itself: the bill grows because the model thinks longer and writes more.

Getting started

Pick GPT-6 Astra Pro from the model list on NetRoom and type your prompt. Attach files and images directly in the dialog; long documents fit into the context in one piece. Billing is in rubles, sign-up is by email, and no separate OpenAI account is needed. If the task turns out simpler than expected, switch to base Astra in the same chat and keep the conversation history.
