Anthropic vs Meta: key differences
Meta built its Model API to take traffic from labs like Anthropic. The endpoint speaks Anthropic Messages as well as OpenAI Chat Completions, so switching is mostly configuration. Muse Spark 1.3 targets agentic coding, tool use and computer use with a 1M context at $1.25 in and $4.25 out, near Haiku 4.5's $1 and $5 and far under Fable 5.1's $10 and $50. A Contributor tier drops prices to $0.10 in and $0.20 out if Meta may train on your prompts, with rate limits falling from 3,000 to 100 requests per minute.
Track record is Anthropic's advantage. Meta's API is still in public preview, while Claude has top results on SWE-bench Pro and wide adoption through Claude Code, plus distribution on every major cloud. Meta covers more modalities on one key, with Muse Image at $0.01 per image and transcription at $0.18 per audio hour, and it offers open-weight Muse Glimmer for self-hosting. Keep production coding and sensitive business traffic on Claude. Use Meta for cost-sensitive experiments and multimodal side tasks, and use the Contributor tier only where sharing data is acceptable.
What Anthropic and Meta do
Anthropic
Anthropic sells the Claude family of closed models through its own API, Amazon Bedrock, Google Vertex AI and Microsoft Foundry. The public lineup today runs from Claude Fable 5.1 at the top, released September 1, 2026, through the Opus and Sonnet tiers down to Haiku 4.5. List prices span a tenfold range, from $10 in and $50 out on Fable to $1 in and $5 out on Haiku. The top three tiers include a 1M token context window at standard pricing with no surcharge past 200K.
Example models: Claude Fable 5.1, Claude Haiku 4.5

Meta has moved from open Llama releases toward its own closed API. Meta Superintelligence Labs builds the Muse family, and in July 2026 Meta opened a public preview of the Meta Model API with Muse Spark 1.1, a multimodal reasoning model aimed at agentic coding, tool use and computer use. The current lineup runs through Muse Spark 1.3 with a 1M token context. Standard pricing is $1.25 in and $4.25 out per million tokens, with cached input at $0.15, and the endpoint speaks OpenAI Chat Completions, Anthropic Messages and a stateful agentic format.
Example models: Muse Spark 1.3, Muse Glimmer
