Meta's Alexandr Wang tells staff the unreleased "Watermelon" model has caught up to GPT-5.5 (July 3, 2026)
At an internal town hall reported on July 3, Meta superintelligence chief Alexandr Wang told employees that the company's next flagship, codenamed Watermelon, has "caught up" to OpenAI's GPT-5.5 on closely watched benchmarks. The model is still training on roughly ten times the compute of Meta's April model, Muse Spark. Wang did not name the benchmarks, and neither Meta nor OpenAI confirmed the claim. OpenAI, meanwhile, has previewed GPT-5.6, with a rollout expected this week.
So what
The frontier is still a four-way race, and a credible Meta contender would give buyers more leverage on price and terms. But a town-hall benchmark claim is not an evaluation artifact, and re-architecting around an unreleased model is a trap. The action: keep at least two frontier models qualified in your stack, and wait for published model cards and independent evals before moving any production workload on the strength of a parity claim.
⚠ Hype check: This is a single-sourced internal claim from Meta's own AI lead, with no benchmarks named and the model still in training. Treat "caught up to GPT-5.5" as a marketing signal, not verified parity.
Confidence: Watch This — the town-hall remarks are widely reported, but the parity claim is unverified and the model is unreleased.
