GPT 5.6 Sol is the best "vision" model OpenAI ever released

OpenAI recently launched the GPT-5.6 lineup, including the Sol, Terra, and Luna models, with a strong focus on computer vision capabilities. While GPT-5.6 Sol demonstrated a 90.7% mean similarity score in OCR, slightly behind GPT-5.5's 91.2%, and 82.5% in text extraction compared to GPT-5.5's 87.6%, it signifies OpenAI's increased commitment to vision. Despite some flaws in cost, latency, and detection, this release significantly enhances OpenAI's offerings for agents, screen understanding, and visual reasoning.
