BIG LAB UPDATES · 27 OCTOBER 2026
Rumour roundup (none of it confirmed)
• Anthropic: @kimmonismus and @Mr_Salio expect a model called 'Fable 5.5' to be released soon; Anthropic hasn't announced anything: x.com and x.com
• Qwen 4: @Mr_Salio says it has been on the LMArena testing site for weeks under the codename 'Kalmia' and could arrive within a week or two: x.com
Why it mattersDon't switch providers on a rumour. If a decision can wait a week, wait for the official release notes and pricing.
