Google's latest thinking model. Excels at reasoning, coding, math, and science with massive context window.
OpenAI's newest flagship model. Improved reasoning, instruction following, and coding over GPT-4o.
OpenAI's most capable multimodal model. Excellent for complex reasoning, coding, and creative tasks.
OpenAI's current flagship chat model (released April 2026). Strongest general reasoning, coding and tool use in the GPT-5 line, with vision input and a large context window.
OpenAI's reasoning model optimized for STEM tasks, coding, and math. Uses chain-of-thought reasoning.
Efficiency-optimized variant of DeepSeek V4. 284B MoE / 13B active, 1M context, ultra-low pricing for high-throughput workloads.
DeepSeek's current Flash model (API name deepseek-flash, model version DeepSeek-V4.1-Flash): 1M-token context, up to 384K output tokens, JSON output, tool calls and vision input.
Small, fast, and affordable model for lightweight tasks. Great balance of speed and capability.
Smaller, faster, cheaper member of OpenAI's GPT-5 family. Tuned for high-throughput chat, classification and extraction where the full flagship is overkill.
OpenAI GPT-5.1 chat model (November 2025). An earlier GPT-5 point release kept available for compatibility. Good general-purpose reasoning and coding.
