GPT-6.1 Sol is OpenAI's upgrade to GPT-6 Sol (1.05M-token context, $2/$10 per million input/output tokens), released September 29, 2026 at DevDay below the flagship GPT-6 Astra. OpenAI says it nearly matches Astra on agentic coding, computer use, and professional work at a fifth of the price, making it a strong default for coding agents and document-heavy workflows.
Claude Haiku 4.5 is Anthropic's fast, affordable small model in the Claude 4 generation, balancing strong instruction-following and coding ability with low latency. It is designed for high-throughput agentic and chat applications where speed and cost efficiency are priorities.
