Claude vs ChatGPT: how the two AI assistants actually differ

[Scarlett]

Engadget put together a genuinely detailed comparison between Claude and ChatGPT, and while both platforms overlap heavily for everyday tasks like coding, answering quick questions and summarizing documents, the piece digs into where they actually diverge once you look past the surface similarities

On raw accuracy, the gap between flagship models is described as marginal, on the AA-Omniscience Accuracy benchmark, Claude Fable 5 scores 61 percent against ChatGPTs GPT 5.6 Sol at 59 percent, a difference small enough youd rarely notice day to day, but the gap widens once you look at the mid tier models most people actually use, Claude Sonnet 5 scores 38 percent versus ChatGPT 5.6 Terra at 46 percent, tipping the scales toward ChatGPT for typical everyday usage rather than flagship comparisons

Hallucination rate is where the piece finds the starkest difference, a lower score is better here, and Claude Fable 5 comes in at 55 percent compared to ChatGPT 5.6 Sols 89 percent, the gap is even wider at the mid tier, Claude Sonnet 5 at 37 percent versus ChatGPT 5.6 Terra at a notably high 85 percent, the article also flags something genuinely counterintuitive, newer ChatGPT models actually score worse on hallucination than older ones, GPT-4o reportedly had a 38 percent hallucination rate compared to GPT-5.6 Sols 89 percent, despite newer models scoring better on most other benchmarks

Usage patterns differ meaningfully too, citing Anthropics own Economic Index from March 2026, 42 percent of Claude conversations are personal use and 45 percent work related, while OpenAIs own data says 70 percent of ChatGPT usage is non work related, on features, Claude Cowork handles knowledge based tasks and file organization, Claude skills work across chat, Cowork and Claude Code, and Claude Artifacts can pull live data through connected apps and MCP connectors, ChatGPT counters with a more natural sounding voice mode that supports real time interruption and live video pointed at physical problems, plus photorealistic image generation that Claude cant match, since Claude is limited to diagrams and interactive visuals built with HTML and SVG

On pricing the two are largely similar, both offer 20, 100 and 200 dollar monthly tiers with increasing usage limits and flagship model access, though ChatGPT has an additional 8 dollar tier that still shows ads, notably OpenAI has started introducing ads into its free and cheaper paid tiers while Anthropic has instead been adding more features to Claudes free tier without ads, the piece also points to a notable user migration event back in February 2026, when Anthropics deal with the US Department of War fell through after the company refused to let its models be used for mass domestic surveillance or fully autonomous weapons, and OpenAI signed a similar deal in its place, a decision the piece says drove many users toward Claude specifically because Anthropic was perceived as the more ethical option
