Overview

  • The two companies launched the models on Tuesday, September 22, with Anthropic releasing Claude Opus 5.5 and OpenAI unveiling GPT-6 Sol plus GPT-6 Luna.
  • OpenAI set GPT-6 Sol at $2 per million input tokens and $10 per million output tokens and priced GPT-6 Luna at $0.10 and $0.50 respectively.
  • Anthropic listed Claude Opus 5.5 at $4 per million input tokens and $20 per million output tokens and says efficiency gains cut typical running costs by about 40 percent.
  • Both firms published vendor-run benchmarks and early tester anecdotes showing strong coding and agent performance, but independent validation of those claims is still needed.
  • Cloud partners including Snowflake, AWS, Google Cloud and Microsoft are offering the new models, shifting enterprise deployments and putting pressure on open-source self-hosted options and vendor margins.
