Weβve added three new frontier AI models to Chatling:
GPT-5.5: OpenAI's new flagship. Stronger reasoning and instruction-following than GPT-5.4, with noticeably fewer hallucinations on knowledge-base grounded answers. Best pick when you need the most accurate, reliable responses and action calling for complex support flows.
Claude Opus 4.8: Anthropic's most capable model yet. Excels at long-context understanding (great for large knowledge bases), nuanced tone, and following detailed brand/persona instructions. Choose this when conversation quality, safety, and handling of long or ambiguous queries matter most.
Gemini 3.5 Flash: The speed option. Near-instant responses, while improving on Gemini 3 Flash in reasoning and multilingual quality.
All three models are now available on Chatling paid plans.
