GPT-6.1 Sol
OpenAI's mid-tier GPT-6 model for agentic coding, computer use, and professional work at a fraction of Astra's price.
Updated 2026-10-06
No free tier is documented for GPT-6.1 Sol.
Listed pricing: $2/$10 per 1M tokens (input/output); cached input $0.10/1M; paid ChatGPT Work/Codex.
Overview
GPT-6.1 Sol is OpenAI's mid-tier GPT-6-class model for agentic coding, computer use, and professional tasks. It is the DevDay 2026 successor to GPT-6 Sol: not a separate consumer chatbot, but a model you reach through the API and paid ChatGPT Work and Codex seats.
The pitch is price-to-capability. OpenAI's September 29, 2026 launch, and TechCrunch's coverage of it, framed GPT-6.1 Sol as approaching flagship Astra performance at about one-fifth the price. API rates are $2 per million input tokens, $10 per million output tokens, and $0.10 per million cached input tokens — the cache rate matters if you run long agent loops that resend the same context.
I'd treat this as the default GPT-6 workhorse for coding agents and computer-use workflows, not as a ChatGPT replacement. Teams that need the absolute top of OpenAI's stack still want Astra. Casual chat users should stay on ChatGPT rather than shopping this SKU.

One plan carries no published number: ChatGPT Work / Codex, recorded as “Included with paid seats”. Nothing is estimated in its place. The vendor's own pricing page is the only source for those figures.

Worth it if
The strengths recorded against this entry.
- Launch positioning is near-Astra quality at roughly one-fifth the price
- Cached input at $0.10 per million tokens for repeated agent context
- Built for agentic coding and computer use, not only chat
- Reachable from the API and from paid ChatGPT Work/Codex without a extra product login
Not worth it if
Any one of these blocks your use case.
- Still the mid-tier GPT-6 SKU; Astra remains the flagship
- Not on free ChatGPT — Work, Codex, or API only
- Independent public eval tables are thinner than the launch narrative; treat 'near-Astra' as OpenAI's claim
- A poor fit if you only need a consumer chatbot and do not run agents or computer use
Key features
Agentic coding
Tuned for multi-step coding work in Codex and similar agent setups, rather than one-shot chatbot replies. That is the intended job, not general small talk.
Computer use
Supports computer-use style tasks where the model operates software, not just generates text. Useful when the workflow is clicking, filling, and navigating rather than answering a prompt.
Cached inputs
Cached input is priced at $0.10 per million tokens, which is the lever for agent runs that reuse a large prefix. Without a cache-heavy workload, you are just paying the standard $2/$10 rates.
Work and Codex
Paid ChatGPT Work and Codex users can select the model inside those products. There is no separate GPT-6.1 Sol app to sign up for.
