Pros and cons
GPT-6.1 Sol
Chatbots · paid
Pros
- ✓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
Cons
- ×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
Grok
Chatbots · freemium
Pros
- ✓Current flagship is documented as Grok 4.6 with published API prices
- ✓SuperGrok Plus fills the old $30-to-$300 gap with a published $100 mid-tier
- ✓X search is a first-party tool, not a third-party plugin
- ✓Grok Build and Grok Bot give two other official places to use the same lab
Cons
- ×Grok Bot and in-chat Build Mode are still Heavy (or top Cursor for Bot), not SuperGrok or SuperGrok Plus
- ×API realtime answers require search tools; the raw model cutoff is February 1, 2026
- ×Weekly usage is one shared pool across Chat, Imagine, Voice, and Build, so video or Build can spend the week quickly
- ×Chat, Build, and Bot are three products with three access rules
