Base44 Adds GPT-5.6 Terra and Sol to AI Chat
Base44Base44 introduced two new GPT-5.6 variants, Terra and Sol, as selectable models in AI chat. Terra is positioned as a cost-efficient option for complex reasoning and multi-step planning, while Sol is the most capable tier for the hardest reasoning tasks and large, evolving projects. The addition rounds out Base44's model lineup with OpenAI's newest reasoning-focused family, alongside the Anthropic and in-house options added earlier in the same stretch.
OpenAI's GPT-5.6 Family Arrives in Base44
Base44 added GPT-5.6 Terra and GPT-5.6 Sol to its AI chat model picker, giving builders two new OpenAI reasoning-tier options alongside Anthropic's Sonnet 5, Base44's own Base 1, and other existing choices.
Terra: Balanced Cost and Capability
GPT-5.6 Terra sits between OpenAI's flagship Sol tier and its lighter-weight Luna tier. Inside Base44, Terra is framed as the cost-efficient choice for complex reasoning and multi-step planning, suited to everyday coding and agentic tasks where builders want strong capability without paying flagship-tier credit costs.
Sol: The Highest-Capability Option
GPT-5.6 Sol is positioned as Base44's most capable GPT-5.6 tier, reserved for the hardest reasoning problems and large, evolving projects that benefit from maximum model capability regardless of cost.
Why It Matters
With Terra and Sol added, Base44 builders gained meaningfully more control over the cost-versus-capability tradeoff when picking a model for a given task, rounding out a lineup that, within roughly two weeks, grew to include Base44's own Base 1, Anthropic's Sonnet 5, and OpenAI's GPT-5.6 Terra and Sol.
