GPT-5.4

GPT-5.4 (March 2026) is the value-flagship: near-top quality on coding, research and math at roughly half the price of GPT-5.5, with native computer-use and a ~1M-token context.

Best for

• The default for most apps: complex coding, analysis, spreadsheets, hard math
• Agentic / computer-use workflows
• Professional knowledge work needing reliable accuracy
• Near-flagship quality on a budget

How it compares — and the India angle

• About 95% of GPT-5.5's everyday quality at half the cost — for most Indian apps this should be the default, not 5.5.
• Accepts text + image input but isn't an image generator — pair it with a dedicated image model.
• Step down to GPT-5.4 mini for cheap bulk traffic; up to GPT-5.5 only for the hardest agentic coding.
